Description

Method, device and equipment for positioning video image frame and computer storage medium

Technical Field

The present application relates to the field of video image processing technologies, and in particular, to a method, an apparatus, and a device for positioning video image frames and a computer storage medium.

Background

With the development of the mobile internet, people also tend to watch online videos or download videos on electronic devices such as computers, mobile phones or tablet computers (PAD). For video in a network, for example, for video in a short video application, a user (i.e., a video provider) usually uploads the video to the network after performing a certain processing, where the processing of the video may generally include video cropping, music matching, and the like.

For video cropping, a user may typically crop an uploaded video through a video cropping tool provided in a short video application or other video editing-like software. However, with the current video cropping tools or video editing software, when the user positions the cropping point during the video cropping, the user usually needs to drag the progress bar repeatedly to find the desired cropping point, and for a video with a long duration, it is particularly difficult to position the cropping point quickly and conveniently because the duration of the video corresponding to the unit length of the progress bar is long.

Therefore, how to more conveniently locate the cropping point when performing video cropping is an urgent technical problem to be solved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. In the present application, the embodiments and features of the embodiments may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

For the convenience of understanding the technical solutions provided by the embodiments of the present application, some key terms used in the embodiments of the present application are explained first:

video progress: in terms of video playing, the video progress refers to a duration corresponding to a currently displayed video picture, and when a video clip is performed, the video progress may be used to indicate a position in a video, where the position may correspond to an image frame, which may be understood as a duration of the image frame from a first frame. After the user adjusts the video progress, the image frames are correspondingly adjusted.

Progress indication area: generally speaking, the progress indication area can indicate the video progress in a progress bar mode, and then the progress indication area is an area where the progress bar is located, and a user can adjust the video progress in a mode of dragging the progress bar or selecting a position on the progress bar; or the video progress can also be directly indicated in a progress value manner, then the region of the real progress value is a progress indication region, and the user can adjust the video progress in a manner of adjusting the progress value or directly inputting the progress value, and of course, the video progress can also be indicated in other possible manners, which is not limited in the embodiment of the present application.

Adjusting precision: refers to the minimum unit of adjustment to the video progress. For example, for a progress bar, the adjustment precision may refer to a video duration corresponding to a unit length on the progress bar, where the unit length refers to a minimum length that can be moved when the progress is dragged, for example, the unit length is 1 millimeter (mm), the video duration corresponding to the unit length is 10 seconds(s), and then the adjustment precision of the progress bar is 10s, that is, dragging the progress bar once will adjust the video progress by at least 10 s; or for the progress value, the adjustment precision may refer to a minimum change value of the progress value, which is adjusted once.

The progress interval: the time interval is an interval formed between one video progress and another video progress, and when the interval corresponds to the progress bar, one progress interval substantially corresponds to a part of the progress bar between one position and another position on the progress bar. For example, if one video schedule is 2 minutes and 6 seconds, and the other video schedule is 3 minutes and 6 seconds, then 2 minutes and 6 seconds to 3 minutes and 6 seconds form a schedule interval, and the schedule interval may correspond to the portion of the schedule bar between the corresponding position of 2 minutes and 6 seconds and the corresponding position of 3 minutes and 6 seconds on the schedule bar.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified. Furthermore, references to "first" or "second", etc. herein are only used to distinguish between similar items and not to describe a particular order or sequence.

Video cropping is a process of extracting a partial video segment from a video, and when the video is cropped, a user needs to select a cropping point, so that the video is divided at the cropping point, and the user can select a reserved part of the video to obtain a final partial video segment. The user can cut the video through a video cutting tool provided in the short video application or other video editing software, but it is difficult to quickly and conveniently locate the cutting point with the current video cutting tool or video editing software.

Fig. 1 is a schematic diagram illustrating a prior art method for locating a cropping point. After entering the video clipping interface, a selection frame can be displayed on the progress bar, two end points of the selection frame are used as a clipping starting point and a clipping end point, and a video segment between the clipping starting point and the clipping end point is a video segment obtained by final clipping. Taking the adjustment of the cropping start point as an example, the user may drag the start point of the selection box to adjust its position on the progress bar, as shown in fig. 1, dragging the cropping start point from position 1 to position 2.

For a specific electronic device, the length of the progress bar is limited, so that when the total duration of the video is short, the video duration corresponding to the unit length of the progress bar is short, and thus the user can also adjust the cropping start point well by repeatedly dragging the progress bar, but when the total duration of the video is long, the video duration corresponding to the unit length of the progress bar is long, for example, the video duration corresponding to the unit length is 10s, the user can adjust the video progress for 10s every time the user drags one unit length, if the cropping point desired by the user is between two progresses, for example, the video progress corresponding to one position on the progress bar is 2 min 06 s, the video progress corresponding to the next position is 2 min 16 s, and the video progress corresponding to the cropping point desired by the user is 2 min 10s, it is difficult for the user to repeatedly drag the progress bar to position the cropping point to 2 min 10s, besides the operation of repeatedly dragging the progress bar is troublesome, the precision of positioning the clipping point by the user is low, and the user experience is seriously influenced.

The applicant analyzes the prior art, and finds that in the prior art, a video clipping tool or video clipping software can only provide an adjustment precision at the same time, and cannot adapt to video clipping scenes with all time lengths for the limited length of a progress bar of electronic equipment, so that the problem that the positioning of a clipping point is difficult when the video time length is longer exists. Therefore, in order to solve the above problems, the limitation that the prior art can only provide a progress bar with one adjustment precision at the same time needs to be eliminated, so as to provide multiple adjustment precisions for users, and users can switch freely, so that the user can conveniently, quickly and accurately position the clipping point desired by the user no matter the video is short or long.

Based on the analysis and consideration, the embodiment of the application provides a method for positioning video image frames, the method displays video progress through a plurality of progress indication areas, adjustment accuracy of different progress indication areas is different, namely, a plurality of selectable adjustment accuracy are provided for a user, and when the user positions the image frames, the position of the image frames can be roughly positioned through the progress indication area with low adjustment accuracy, and then the position of the image frames can be accurately positioned through the progress indication area with high adjustment accuracy. Therefore, for the video with longer time, the probability that the video with longer time is difficult to select the desired image frame position due to the fact that the time length of the video corresponding to the unit length of the progress bar is larger can be reduced, and therefore, even for the video with longer time, a user can conveniently, quickly and accurately position the desired image frame position.

In addition, since a plurality of progress indication areas are simultaneously displayed, a user can quickly switch a progress indication area desired to be adjusted, thereby improving flexibility and speed of image frame positioning.

In the embodiment of the application, the display modes of various progress indication areas are provided for a user, one mode can adopt the mode of the progress bar to display the video progress, the other mode can also display the video progress in a progress value mode, no matter which display mode, a plurality of progress indication areas can be provided for the user, and the user can conveniently, quickly and accurately position the desired image frame position.

After introducing the design concept of the embodiment of the present application, some simple descriptions are provided below for application scenarios to which the technical solution of the embodiment of the present application can be applied, and it should be noted that the application scenarios described below are only used for describing the embodiment of the present application and are not limited. In a specific implementation process, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.

The positioning method of the video image frame in the embodiment of the application can be applied to a scene of video clipping, and can also be applied to application scenes such as video playing or video screenshot.

Referring to fig. 2, a scene diagram illustrating an example of a cropping scene for a video is shown, and the application scene may include a terminal device 201 and a server 202. The terminal device 201 is connected to the server 202 through a wireless or wired network, the terminal device 201 is an electronic device with a video clipping function, such as a smart phone, a tablet computer, an intelligent robot, a motion sensing game device, and a VR (Virtual Reality) device, and the server 202 is a server or a server cluster or a cloud computing center formed by a plurality of servers.

An application containing a video cropping function, which may be, for example, a video application, a short video application, or video cropping software, may be installed in the terminal device 201.

Taking the application as a video application or a short video application as an example, the server 202 may be a background server of the video application or the short video application. The user can publish own video through the video application or the short video application, and before the video is published, the user can clip the original video through a video clipping tool provided by the video application or the short video application. When a user uses a video cropping tool to crop, the cropping point can be located by using the method for locating a video image frame provided by the embodiment of the present application, so that an original video is segmented based on the cropping point, or the cropping point is used as a starting point or an end point of a video segment, the original video is cropped to obtain a video segment which needs to be finally distributed, and the video segment is uploaded to a server 202 for storage, or is distributed to an account in a video application or a short video application, and other users who can view the account video of the user can view the video distributed by the user.

Taking the application as video cropping software as an example, then the server 202 may be a background server for video applications or short video applications, or the server 202 may be a background server for web disk applications. The user can clip the original video through the video clipping software, wherein when the user clips with the video clipping tool, the clipping point can be located by using the positioning method of the video image frame provided by the embodiment of the application, so that the original video is divided based on the clipping point, or the clipping point is used as the starting point or the end point of the video segment, and the original video is clipped to obtain the final video segment. A user can publish a finally obtained video clip to a video application or a short video application corresponding to the server 202 through a video sharing or video publishing function provided by the video clipping software; alternatively, the information may be saved locally or in a network disk corresponding to the server 202.

The application scenario shown in fig. 2 may also be applied to a video playback scenario. The terminal device 201 may also have a video application or a short video application, and the server 202 may be a background server for the video application or the short video application.

Taking a video application as an example, a user may select a video that the user wants to play from the video application, and the video application may pull a video stream from the server 202 to play the video. In the process of playing the video, a user can adjust the video progress at any time, and when the user adjusts the video progress, the positioning method of the video image frame provided by the embodiment of the application can be used for positioning the target image frame which the user wants to adjust, and then the subsequent video is continuously played by taking the target image frame as a starting point. Meanwhile, when the video application acquires the target image frame selected by the user, the server 202 may also be notified of the target image frame, and the server 202 may provide the video application with a video stream starting from the target image frame.

The playing process of the short video application is similar to the process of the video application, and therefore, the detailed description thereof is omitted.

The application scenario illustrated in fig. 2 may also be applied to a video screenshot scenario. The terminal device 201 may also have a video application or a short video application, and the server 202 may be a background server for the video application or the short video application.

Taking a video application as an example, a user may select a video that the user wants to play from the video application, and the video application may pull a video stream from the server 202 to play the video. During the video playing process, when a user views a wonderful picture, the corresponding image frame can be intercepted from the video. Specifically, when image frame capture is performed, the target image frame to which the user wants to adjust can be located by using the video image frame locating method provided by the embodiment of the present application, and then the target image frame is captured.

For the video screenshot scene, the application scene may also be a scene schematic diagram as shown in fig. 3. Terminal device 301, server 302, server 303, and terminal device 304 may be included in this scenario. The server 302 may be, for example, a background server of a video application or a short video application, and the server 303 may be, for example, a background server of an instant messaging application or a background server of a content sharing application.

Taking a video application as an example, a user a may pull a video stream from the server 302 through the video application installed in the terminal device 301 to play a video, and in the process of watching, may position a target image frame that the user a wants to adjust to by using the positioning method of the video image frame provided in the embodiment of the present application, and further intercept the target image frame, and link to the instant messaging application installed in the terminal device 301 by using the sharing function of the video application or the short video application terminal, so as to send a screenshot sharing request to the server 303 through an account of the instant messaging application, so that the intercepted target image frame is shared to a friend in the instant messaging application through the server 303, for example, a user B, who may view the target image frame of the user a through the terminal device 304; or, the content sharing application installed in the terminal device 301 is linked to the sharing function of the video application or the short video application terminal, so that a screenshot issuing request is sent to the server 303 through the account of the content sharing application, and the intercepted target image frame is issued to the account of the content sharing application through the server 303.

It should be noted that the above description is given by taking an application as an example, such as a video application or a short video application, and the above process is also applicable to a web page in the implementation process.

The devices that need to communicate with each other may be communicatively connected through one or more networks, where the network may be a wired network, or may also be a WIreless network, for example, the WIreless network may be a mobile cellular network, or may be a WIreless-Fidelity (WIFI) network, and of course, other possible networks may also be used, which is not limited in this embodiment of the present application.

Of course, the application scene of the embodiment of the present application may also only include the terminal device, and then the user may perform positioning of the video image frame on the local video of the terminal device by using the positioning method of the video image frame provided in the embodiment of the present application, so as to continue subsequent functions of clipping, screenshot, playing, and the like.

Of course, the method provided in the embodiment of the present application is not limited to be used in the application scenario shown in fig. 2 or fig. 3, and may also be used in other possible application scenarios, and the embodiment of the present application is not limited. Functions that can be implemented by each device in the application scenario shown in fig. 2 or fig. 3 will be described together in the following method embodiment, and will not be described in detail herein.

Referring to fig. 4, a flowchart of a method for positioning video image frames according to an embodiment of the present application is shown, where the method may be performed by the terminal device shown in fig. 2 or fig. 3, and a flow of the method is described as follows.

Step 401: and responding to the display operation of the user on the target video, and displaying the video progress in the progress display area.

In the embodiment of the application, the progress display area may display the video progress in a plurality of ways, for example, the video progress may be displayed in a progress bar manner, or the video progress may be displayed directly in a progress value manner. Specifically, each progress display area may display the video progress in the same manner, for example, the first progress display area and the second progress display area both adopt a progress bar manner or a progress value manner, or each progress display area may also display the video progress in different manners, for example, the first progress display area adopts a progress bar manner and the second progress display area adopts a progress value manner.

When the progress of the video is displayed in a progress bar manner, the progress bar may adopt various styles. For example, a square bar-shaped progress bar pattern as shown in fig. 5A or fig. 5D may be adopted, or a cylindrical bar-shaped progress bar pattern as shown in fig. 5B or fig. 5E may be adopted, or a ring-shaped progress bar pattern as shown in fig. 5C or fig. 5F may also be adopted, of course, fig. 5A to fig. 5F only list some available progress bar patterns, and in practical applications, other possible progress bar patterns may also be adopted, which is not limited in this application.

In a specific implementation process, the progress indication manner may be adaptively selected for different application scenes, for example, for a video capture scene or a video cropping scene, a user may be more concerned about the position of an image frame where a cropping point is located, and thus the progress indication manner shown in fig. 5A to fig. C may be adopted; for the video playing scene, the user may want to more clearly distinguish the video segments that have finished playing from the video segments that have not finished playing, and thus the progress indication manner shown in fig. 5D to fig. F may be adopted.

When the video progress is displayed in a progress value mode, the progress can also be displayed in various modes.

As shown in fig. 6A, a schematic diagram of displaying the video progress in a progress value manner, where the progress value may display the current video progress in a numerical percentage manner, and of course, may display the current video progress in a manner of time in the video as the current video progress. As shown in fig. 6A, when the progress value is adjusted by the progress value adjustment button, "-" is used for the forward adjustment of the progress and "+" is used for the backward adjustment of the progress.

Fig. 6B is another schematic diagram showing video progress in a progress value manner. As shown in fig. 6B, the adjustment button may be dragged to adjust the progress value by selecting the video progress display area to pop up an adjustment progress bar including the adjustment button.

In the embodiment of the application, the display interface can comprise a plurality of progress display areas, namely a first progress display area and a second progress display area, wherein a user can adjust the video progress displayed by each progress display area, and the adjustment accuracy of the video progress of each progress display area is different. For example, the adjustment accuracy of the video progress of the second progress indication area may be greater than the adjustment accuracy of the video progress of the first progress indication area.

As shown in fig. 7, a schematic diagram of a progress display area is taken as an example of a progress bar. The first progress bar in the first progress display area may be a normal progress bar, that is, the first progress bar may show all the progress of the target video, and the second progress bar in the second progress display area may be a local enlargement progress bar, that is, the progress bar in the first progress display area may only show the video progress of a partial video clip of the target video, and corresponds to the first progress bar, and then the second progress bar may only correspond to a partial progress interval on the first progress bar. As shown in fig. 7, the second progress bar corresponds to the AB progress interval on the first progress bar, that is, the video segment corresponding to the second progress bar is the video segment corresponding to the AB progress interval in the target video. And the adjustment precision of the second progress bar is greater than that of the first progress bar, that is, for the same video, the video time length corresponding to the unit length of the second progress bar is less than that corresponding to the unit length of the first progress bar. As shown in fig. 7, when the duration of the target video is determined, the video may advance or retreat by 5s for each unit length movement on the first progress bar, and advance or retreat by 1s for each unit length movement on the second progress bar, so that the video image frames may be roughly positioned based on the first progress bar and precisely positioned based on the second progress bar.

Wherein, for convenience show unit length in fig. 7, therefore show in the progress bar and have carried out the enlarged show with scale mark and unit length, but when actually showing, can not show the scale mark, and unit length can set up according to actual conditions.

In practical applications, the number of the second progress bars displayed in the second progress display area may be 1 (specifically, this is taken as an example in fig. 7), or may be M, where M is a positive integer greater than 1. When the number of the second progress bars is M, the adjustment precision of the second progress bar may be in a certain gradient level, that is, the video duration corresponding to the unit length of the M-level second progress bar may be gradually decreased step by step.

As shown in fig. 8, a schematic diagram of an M-level second progress bar displayed for the second progress display area. Specifically, in fig. 8, the 3-level second progress bar is taken as an example, where, for the target video, the 1 st-level second progress bar corresponds to an AB progress interval on the first progress bar, the video duration corresponding to the unit length is 1s, the 2 nd-level second progress bar corresponds to a CD progress interval on the 1 st-level second progress bar, the video duration corresponding to the unit length is 0.5s, the 3 rd-level second progress bar corresponds to an EF progress interval on the 2 nd-level second progress bar, and the video duration corresponding to the unit length is 0.1s, that is, as the level increases, the video duration corresponding to the unit length of the second progress bar may gradually decrease, and the adjustment accuracy may be higher and higher.

As shown in fig. 9, a schematic diagram of a progress display area taking a progress value as an example. And the adjustment precision of the first progress display area is lower than that of the second progress display area. As shown in fig. 9, the adjustment accuracy of the first progress display area is 1%, that is, each adjustment can advance or retreat the video progress by 1%, and the adjustment accuracy of the second progress display area is 0.1% and 0.01%. Of course, fig. 9 is only an illustration, and in actual application, the adjustment accuracy and the number of numerical steps of the second progress display area may be specifically set according to actual conditions.

In the embodiment of the application, the video schedules displayed in the first progress display area and the second progress display area can be displayed simultaneously, or the video schedule of the first progress display area is only displayed, and the video schedule of the second progress display area is only displayed based on certain condition triggering. The progress bar is described as an example.

In one possible implementation manner, the user can perform a first display operation on the target video, and the terminal device displays the first progress bar and the second progress bar in response to the first display operation performed on the target video by the user.

Specifically, when the user clips the target video, the first display operation may be a clipping start operation performed after the user selects the target video. As shown in fig. 10, after the user selects video 1 in the video selection interface, the user may operate the start cropping button to jump to the video cropping interface, and the first progress bar and the second progress bar may be directly displayed on the jumped video cropping interface. Of course, in practical applications, after the user selects a video and uploads the selected video, a start cropping operation may be performed to jump to the video cropping interface.

On the initial video clipping interface, because a user does not select any frame of image frame, blank image frames can be displayed in a video image display area, or initial frames of a target video are displayed, or a video cover of the target video is displayed, for a first progress bar, according to the duration of the video and by combining the total length of the first progress bar, the video duration corresponding to each unit duration on the first progress bar can be calculated, and then the mapping relation between each position on the first progress bar and the video progress is established locally, and because each video progress corresponds to an image frame in the video, the mapping relation can be substantially understood as the mapping relation between each position on the first progress bar and each image frame in the video.

For a bar-shaped progress bar, the total length of the progress bar refers to the total width between the left end point and the right end point of the progress bar; while for a circular progress bar, the total length of the progress bar may refer to the circumference of the inner or outer ring.

Specifically, when the user captures the target video, the first display operation may be an operation performed by the user on a capture button on the video playing interface, after the user operates the capture button, the user may enter a capture interface for adjusting the image frame, and the first progress bar and the second progress bar may be directly displayed on the capture interface.

Specifically, when the user plays the target video, the first display operation may be a play operation performed on the target video by the user, that is, the first progress bar and the second progress bar may be directly displayed on the skipped video play interface; or, in the process of playing the video, in order to avoid blocking the video interface, the progress bar is not usually displayed, so the first display operation may also be a progress bar display operation performed in the process of playing the video, for example, the operation may be a click on the video interface, and after the terminal responds to the operation, the first progress bar and the second progress bar may be directly displayed on the video playing interface.

In a possible implementation manner, whether to display the second progress bar and the number of the second progress bars to be displayed can be intelligently determined according to the duration of the target video. Specifically, after the user performs the second display operation on the target video, the terminal device responds to the second display operation performed on the target video by the user, obtains the duration of the target video, and determines whether the second progress bar needs to be displayed according to the duration of the target video, for example, when the duration of the target video is short, the target image frame can be well positioned only through the first progress bar, so that only the first progress bar can be displayed; when the duration of the target video is longer, the video duration corresponding to the unit length on the first progress bar is very long, which is not beneficial to positioning the target image frame, so that the second progress bar can be displayed, the number of stages M of the second progress bar required to be displayed can be judged according to the specific duration of the video, and the greater the duration of the target video is, the greater M can be.

The second display operation may be the same as the first display operation, for example. For example, when the user clips the target video, the second display operation may be a clipping start operation performed after the user selects the target video, that is, after the user starts clipping, whether to display the second progress bar and the number of the second progress bars to be displayed may be determined according to the duration of the video to be clipped; or, when the user captures the target video, the second display operation may be an operation performed by the user on a capture button on the video playing interface; or, when the user plays the target video, the second display operation may be a playing operation performed on the target video by the user.

In a possible implementation manner, the display of the second progress bar may be triggered in response to the third display operation performed by the user when the third display operation satisfies a certain display condition. For example, the third display operation may be an operation performed by the user with respect to the displayed first progress bar, for example, if the user stays at a certain position on the first progress bar for more than a preset time period, the second progress bar is displayed based on the position.

Step 402: and responding to a first progress adjusting operation performed by a user aiming at the first progress indicating area, and adjusting the video progress displayed in the first progress indicating area to obtain the adjusted first video progress.

In the embodiment of the application, when the user performs image frame positioning, the user may first perform a first progress adjustment operation on the first progress indicating area to adjust the progress of the video displayed in the first progress indicating area to an approximately desired image frame position.

And the video progress corresponding to the position selected by the user can be obtained based on the mapping relation established for each progress bar.

Specifically, when the first progress indication area displays the video progress in a progress bar manner, the first progress adjustment operation may be an operation of dragging on the first progress bar, or an operation of directly clicking a certain position on the first progress bar. Based on the first progress adjustment operation, a first position can be selected from the first progress bar, based on the mapping relation established for the first progress bar, a first video progress corresponding to the first position can be obtained, and an image frame corresponding to the first video progress is displayed in the video image display area.

When the user drags on the first progress bar, the video image display area can display the image frame corresponding to the dragged position along with the dragging of the progress bar, and the user can judge whether the image frame reaches the image frame position required by the user according to the image frame displayed in the video image display area. Or, the playing progress duration corresponding to the current position may be calculated according to the position dragged by the user on the first progress bar, or the distance between the clicked position and the initial position of the first progress bar, so that the corresponding image frame is displayed in the video image display area.

Specifically, when the first progress indication area displays the video progress in a progress value manner, the first progress adjustment operation may be an operation of increasing or decreasing the progress value, as shown in fig. 6A, the first progress adjustment operation may be an operation performed on "-" or "+", and correspondingly, during or after the adjustment, the corresponding image frame may be displayed in the video image display area.

In the embodiment of the application, in order to further accelerate the speed of positioning the video image frames by the user, the summary image frames in the video clips corresponding to the progress intervals on the first progress bar and/or the second progress bar may also be obtained, where the summary image frames are used to represent main video content in the video clips, and the summary image frames of the corresponding video clips are displayed at the set positions of the progress intervals on the first progress bar and/or the second progress bar.

The summary image frames in the video clips corresponding to the progress intervals can be obtained through video content analysis, the summary image frames are the image frames which can most express the content of the video clips in the video clips corresponding to the progress intervals, the set positions can be specifically set according to actual conditions, and for example, for a strip-shaped progress bar, the summary image frames can be displayed above the progress intervals. As shown in fig. 11, in order to display the summary image frame above the second progress bar as an example, a summary image frame display diagram is shown, wherein the corresponding summary image frame above each progress interval expresses a summary of the content of the video segment corresponding to each progress interval, so as to assist the user to better identify the video image frame and the video segment that the user wants to locate.

Step 403: and updating the video progress displayed in the second progress indication area according to the first video progress.

In the embodiment of the application, after the user selects the first position in the first progress indication area, the second progress indication area is correspondingly updated.

When the video progress is displayed in a progress bar mode, the mapping relation between each position on the second progress bar and the video progress can be updated by taking the first video progress corresponding to the first position selected in the first progress bar by the first progress adjustment operation as a reference.

Specifically, since the second progress bar of the second progress indication area is substantially an enlarged version of a partial progress interval of the first progress bar of the first progress indication area, and the partial progress interval may be a progress interval expanded based on the first video progress selected by the user as a reference, when the mapping relationship between each position on the second progress bar and the video progress is updated, the start progress and the end progress of the second progress bar may be determined according to the first video progress, and then the video progress corresponding to each position on the second progress bar may be determined according to the duration of the video clip between the start progress and the end progress and the unit duration of the second progress bar, so as to establish the mapping relationship between each position in the second progress bar and the video progress.

In specific implementation, the first preset duration can be extended forward by taking the first video progress as a reference. If the duration between the first video progress and the initial progress of the target video is less than the first preset duration, the initial progress of the second progress bar may be the initial progress of the target video; when the duration between the first video progress and the initial progress of the target video is not less than the first preset duration, the initial progress of the second progress bar may be a third video progress which is before the first video progress and is away from the first video progress by the first preset duration.

In specific implementation, the second preset duration may also be extended backwards based on the first video progress. If the duration between the first video progress and the termination progress of the target video is less than a second preset duration, the termination progress of the second progress bar may be the termination progress of the target video; when the duration between the first video progress and the termination progress of the target video is not less than the second preset duration, the termination progress of the second progress bar may be a fourth video progress which is after the first video progress and is away from the first video progress by a second preset duration.

The values of the first preset time and the second preset time can be set according to specific conditions, and the values of the first preset time and the second preset time can be the same or different.

As shown in fig. 7, when the first video progress selected by the user is shown in the position in fig. 7, a progress interval corresponding to the second progress bar, that is, an AB progress interval, may be obtained by expanding a certain video progress left and right with reference to the first video progress. For example, the first preset time duration and the second preset time duration are both 30 seconds, when the selected first video progress is 2 minutes and 06 seconds, the AB progress interval may be 1 minute and 36 seconds to 2 minutes and 36 seconds, that is, the starting progress of the second progress bar is 1 minute and 36 seconds, and the ending progress of the second progress bar is 2 minutes and 36 seconds.

When the second progress indication area includes M-level second progress bars, after the first video progress is selected on the first progress bar, only the mapping relationship of the second progress bar with the maximum video duration corresponding to the unit length in the M-level second progress bars is updated by taking the first video progress as a reference, that is, only the mapping relationship of the 1 st-level second progress bar is updated. Or, the mapping relationship of a plurality of or all of the M-level second progress bars may be updated with the first video progress as a reference.

In this embodiment of the application, when the user performs a third progress adjustment operation on the ith-level second progress bar, the mapping relationship in the ith-level second progress bar is updated, based on a third video progress corresponding to a third position selected by the third progress adjustment operation in the ith-level second progress bar, where the video duration corresponding to the unit length is smaller than that of the ith-level second progress bar, in response to the third progress adjustment operation. For example, if the user performs a third progress adjustment operation on the level 1 second progress bar, the mapping relationship of the second progress bar located after the level 1 second progress bar, such as the mapping relationship of the level 2 second progress bar or the mapping relationship of the level 3 second progress bar, may be updated based on a third video progress corresponding to the third progress adjustment operation.

In a possible implementation manner, a user may select a position in the first progress bar, and then update the mapping relationship of the level 1 second progress bar with the video progress corresponding to the position, and the user may also select a position in the level 1 second progress bar, and then update the mapping relationship of the level 2 second progress bar with the video progress corresponding to the position, and the user may also select a position in the level 2 second progress bar, and then update the mapping relationship of the level 3 second progress bar with the video progress corresponding to the position, and so on.

When the progress of the video is displayed in a progress value manner, then the progress adjustment operation performed for each progress indication area is used to adjust the value size of the progress value.

Specifically, after the user performs the first progress adjustment operation on the first progress indication area, the video progress of the first progress indication area is adjusted to the first video progress, and correspondingly, the first video progress may be displayed in the second progress indication area in a manner of being adapted to the adjustment accuracy of the second progress indication area. As shown in fig. 9, when the video progress of the first progress indicating region is adjusted to 75%, 75.0% and 75.00% may be displayed in the second progress indicating region.

Step 404: and responding to a second progress adjusting operation of the user aiming at the second progress indicating area, and adjusting the video progress displayed in the second progress indicating area to obtain the adjusted second video progress.

In the embodiment of the application, after the user performs rough image frame positioning through the first progress indication area, a second progress adjustment operation may be performed on the second progress indication area to adjust a progress of a video displayed in the second progress indication area, so as to more accurately position a desired image frame position.

Specifically, when the video progress is displayed in a progress bar manner, the second progress adjustment operation may be an operation of dragging on the second progress bar, or an operation of directly clicking a certain position on the second progress bar. Based on the second progress adjustment operation, a second position can be selected from the second progress bar, based on the mapping relationship of the second progress bar obtained after the updating in the step 403, a second video progress corresponding to the second position can be obtained, and an image frame corresponding to the second video progress is displayed in the video image display area.

When the second progress indication area includes M-level second progress bars, the second progress adjustment operation may include a plurality of progress adjustment sub-operations, each of the progress adjustment sub-operations is used to select a second position on one of the second progress bars, and after each time the user performs the progress adjustment sub-operation, a second video progress corresponding to the second position selected by the progress adjustment sub-operation may be determined according to the progress adjustment sub-operation performed by the user and a mapping relationship of the second progress bar targeted by the operation, and an image frame corresponding to the determined second video progress is displayed in the video image display area. Of course, the video image display area may display a frame of image, and may also display multiple frames of images, so that a second video schedule may be obtained when the user performs a schedule adjustment sub-operation, and then image frames corresponding to each determined second video schedule may be simultaneously displayed in the video image display area, and then the user may select from the multiple image frames when determining the target image frame.

Specifically, when the video progress is displayed in a progress value manner, the second progress adjustment operation may be an operation of increasing or decreasing the progress value, and the progress value displayed in the second progress indication area is adjusted according to the adjustment accuracy of the second progress indication area in response to the second progress adjustment operation. Accordingly, during or after the adjustment, the corresponding image frame can be displayed in the video image display area.

Step 405: and in response to the confirmation operation of the user on the image frame corresponding to the second video progress, determining the image frame corresponding to the second video progress as the target image frame.

In the embodiment of the application, in the process that the user adjusts the video progress through the second progress indication area, the video image display area may preview and display the image frame corresponding to the currently adjusted second video progress, so that when the user previews the image frame that the user wants, a confirmation operation may be performed on the image frame, and the terminal device may determine the image frame corresponding to the second video progress as the target image frame. Of course, if the user finds a desired image frame only by adjusting the first progress indicating area, a confirmation operation may also be performed, so that the image frame corresponding to the first video progress after the first progress indicating area is adjusted is determined as the target image frame.

When the user clips the target video, the confirmation operation may be a confirmation clipping operation, and after the user confirms the clipping operation, the image frame corresponding to the second video progress may be determined as the target image frame, that is, the image frame displayed in the current video image display area is determined as the target image frame, and the target image frame is used as a start image frame or a stop image frame of the target video segment to be acquired to clip the target video.

When a user divides a target video, the video division is to divide the target video into two video segments, and is also a video clipping method in essence. Accordingly, the confirmation operation may be a confirmation dividing operation, and the image frame corresponding to the second video progress may be determined as the target image frame, that is, the image frame displayed in the current video image display area is determined as the target image frame, and the target video is divided into two video segments by using the target image frame as a dividing point. Based on the above process, the user can divide the target video into a plurality of video segments through multiple divisions, delete the video segment that is desired to be discarded, and further splice the remaining video segments together to form a new video.

When the user captures the target video, the confirmation operation may be a capture operation, and the image frame corresponding to the second video progress may be determined as the target image frame, that is, the image frame displayed in the current video image display area is determined as the target image frame, and the target image frame is captured from the target video.

When the user plays the target video, the confirmation operation may be a video playing operation, and the image frame corresponding to the second video progress may be determined as the target image frame, that is, the image frame displayed in the current video image display area is determined as the target image frame, and the target video is played with the target image frame as a playing starting point.

Fig. 12 is a flow chart illustrating a specific video cropping process.

Step 1201: the user selects the target video and confirms the start of cropping.

Step 1202: and jumping to a video clipping interface, and displaying two progress bars on the video clipping interface.

As shown in fig. 13, the two progress bars are a progress bar a and a progress bar B, respectively, where the progress bar a is a normal progress bar corresponding to a complete target video, and the progress bar B is a partially enlarged progress bar corresponding to a partial video clip of the target video.

When jumping to the video cropping interface, an image index can be established for each frame of the target video, the duration of the target video is read, and the video duration corresponding to each millimeter on the progress bar a is calculated by combining the total length of the progress bar a, so that each position on the progress bar a corresponds to one video progress duration, and thus corresponds to one image index.

Step 1203: and calculating the current playing progress duration t according to the position selected by the user aiming at the adjustment operation of the progress bar A, and displaying the index image corresponding to the current playing progress duration in the video image display area.

Step 1204: and judging whether the current playing progress time length t is less than 30s from the title.

Step 1205: and judging whether the current playing progress time length t is less than 30s from the end of the title.

In the embodiment of the application, the progress bar B corresponds to the video duration of 1 minute on the progress bar a, and the video duration of 30s is extended from front to back based on the play progress duration corresponding to the position selected by the adjustment operation as the center, so that when the progress bar B is updated, whether the current play progress duration t is less than 30s from the leader and the trailer or not needs to be judged.

Step 1204 and step 1205 may be executed simultaneously or sequentially.

Step 1206: if the determination result in the step 1204 is yes, it is determined that the progress bar B is set to 0: 00 is the starting time point.

Step 1207: if the determination result in the step 1204 is negative, it is determined that the progress bar B starts at the time point t-30 s.

Step 1208: if the determination result in the step 1205 is yes, it is determined that the end-of-segment time of the progress bar B is the termination time point.

Step 1209: if the determination result in the step 1205 is negative, it is determined that the progress bar B takes t +30s as the termination time point.

Step 1210: and updating the progress bar B according to the determined starting time point and the determined ending time point.

As shown in fig. 13, when the current playing progress time t is 2 minutes 36 seconds, the starting time point and the ending time point of the progress bar B are 2 minutes 06 seconds and 3 minutes 36 seconds, respectively, and the playing progress time corresponding to each position on the progress bar B also changes, so that updating the progress bar B may include updating the displayed starting time point and ending time point, and may also include updating the mapping relationship between each position on the progress bar B and the playing progress time.

In order to make the user more clearly know the progress interval in the progress bar a corresponding to the progress bar B, a certain mark may be adopted in the progress bar a, and the progress interval corresponding to the progress bar B is marked, for example, a solid frame or a color (shown in fig. 13) may be adopted for marking.

Step 1211: the operation behavior of the user is monitored.

Step 1212: if it is monitored that the user performs adjustment operation on the progress bar a, the process jumps to step 1203 for execution.

Step 1213: if it is monitored that the user performs the adjustment operation on the progress bar B, the process jumps to step 1214 to be executed.

Step 1214: and calculating the current playing progress duration t according to the position selected by the user aiming at the adjustment operation of the progress bar B, and displaying the index image corresponding to the current playing progress duration in the video image display area.

As shown in fig. 13, when the user drags to 02 minutes 36 seconds on the progress bar a, the range of 1 minute left and right is marked by a color mark, the leftmost side of the progress bar B is 02 minutes 06 seconds, the rightmost side is 03 minutes 06 seconds, the user can directly slide the finger on the progress bar B for adjustment, or the user can move the finger away first, and then slide the finger left and right on the progress bar B to select a finer time point.

The user's operation on the progress bar a may affect the starting time point and the ending time point of the progress bar B, but dragging on the progress bar B may not affect the selection range on the progress bar a, and when the user performs an adjustment operation on the progress bar B, the time progress mark on the progress bar a may be hidden.

Step 1215: if the user operation of the confirm crop button is detected, the process proceeds to step 1216.

Step 1216: and generating a cropping mark at the time length position of the current playing progress, and dividing the video into two segments based on the cropping mark.

To sum up, the video image frame positioning method provided by the embodiment of the application provides multiple adjustment precisions for a user by providing multiple progress indication areas for the user, and the user can selectively perform coarse positioning and fine positioning, thereby improving the convenience of positioning the video image frame of the user. For example, when a user cuts a video, the user can stop at any position on the progress bar, the video of a period of time around the currently selected progress can be enlarged by a locally enlarged progress bar, if the user wants to enter fine editing, the user can directly move fingers to the locally enlarged progress bar for editing, meanwhile, the user can return to the original progress bar at any time for editing, and the situation that the user cuts the video by enlarging and reducing the current progress back and forth is avoided, and as shown in the above fig. 13, the operation interface is clear and concise, the learning cost of the user is low, and the controllability is higher.
