It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The video editing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1, an embodiment of the present application provides a video editing method, which may include the following steps 101 to 105:

step 101:

a first input is received for a first thumbnail within a first region in a video editing page.

The video editing page may be a page corresponding to a video editing function in video editing software, or a page in a browser, and the like, which is not limited in the embodiment of the present application. The video editing page can be displayed on a display screen of the electronic device, wherein when the display screen cannot display all contents of the video editing page, all contents of the video editing page can be displayed in a sliding or page-turning manner, for example, a user can touch a blank of the video editing page on a touch display screen of a mobile phone, slide in the up, down, left and right directions and the like without lifting a finger, and display all contents of the video editing page in a sliding manner, or input and display the contents of the video editing page in a page-turning manner.

In an embodiment of the present application, a video editing page may include three regions: a first region for displaying a thumbnail of an original video material; a second area for displaying thumbnails of the divided video clips; and a third area for displaying thumbnails of the candidate video segments of the spliced video. That is, the contents displayed in the three areas are thumbnails of the corresponding videos/video clips.

For example, fig. 2 is an alternative interface interaction diagram of a video editing page. As shown in fig. 2, the video editing page includes a first area 201, a second area 202 and a third area 203, in some application scenarios, the contents of three regions of a video editing page may not be simultaneously displayed on the screen due to the limitations of the screen presentation area, and, then, the display can be performed by the above-mentioned sliding or page-turning manner, and an alternative example is that the display space of three areas in the video editing page is preset, is fixed, in the case where the content in any one area cannot be completely displayed in the preset display space, the area may be subjected to pagination display, for example, in the second area 202 shown in fig. 2, since there are too many thumbnails, they cannot be fully presented in the second area 202, pages may be paged and the user may select which thumbnail of page is currently displayed by entering the page flip input icon 205.

The first area is used for displaying at least one thumbnail corresponding to at least one video.

The thumbnail may be a dynamic image generated from a plurality of frame images extracted in a corresponding video (or video clip). For example, the dynamic graph may be a GIF Format (Graphics exchange Format, translatable to a Graphics exchange Format) dynamic graph. The dynamic image generated by the multi-frame image is used as the cover of the video, more information can be displayed than a static image, a user can conveniently and quickly preview more contents of the video, the user can conveniently determine the video according to the thumbnail, the video is represented in the form of the thumbnail, the thumbnail in the shape of a card can be conveniently clicked, dragged, sorted and the like, and the operation is convenient and quick.

Optionally, the number of extracted frames or the extraction time interval may be set in advance, and the specific setting mode may be user-defined or factory default setting.

For example, for a first video, 10 frames of images may be extracted to generate a dynamic image in advance, and when the first video needs to be added to the first area, 10 frames of images may be extracted at the same time interval for the first video, and then the 10 frames of images are synthesized into a dynamic image in the extraction order, and the dynamic image is used as a thumbnail of the first video, and the thumbnail is dynamically displayed in the first area.

The video displayed in the first area may be part or all of the video in the local video set, and optionally, the user may select part of the video in the local video set to be displayed in the first area. The videos in the local video collection may be locally generated (e.g., recorded or edited) or downloaded over a network to a local video.

For example, the thumbnails displayed in the first area may be displayed in a certain layout. In one example, when thumbnails are displayed in the first region, the display may be performed based on a preset layout manner in an order selected by a user.

For example, when a user browses videos on the internet, the user can download interested videos and store the videos to the local part of the mobile phone; for another example, a user can record a video segment through a mobile phone and store the video segment locally in the mobile phone; the user may then select to "open" the local video collection after opening the video editing software, select at least one video in the video list that may be needed to edit the video, and display a thumbnail of the selected video in the first area after the user determines the selection. Specifically, after the user determines to select at least one video, 15 frames of images are randomly extracted for each video, the extracted 15 frames of images are combined into dynamic thumbnails in the order in the video, and further, thumbnails of the videos selected by the user are additionally displayed behind the currently displayed thumbnails in the first area. If the requirement is met, the video in the local video set can be continuously selected to be added into the first area.

The first input is used for indicating that the video corresponding to the thumbnail image receiving the first input is subjected to video segmentation and is segmented into a plurality of video segments. The first input may be an operation input received through an interactive device such as a mouse, a keyboard, a touch screen, and the like, and a specific form of the operation input may be preset, for example, a user may press a thumbnail for a long time on the touch screen, or click the thumbnail through a left mouse button, and the like. After receiving the first input, step 102 is performed.

Step 102:

in response to a first input for a first thumbnail, a first video corresponding to the first thumbnail is divided into a plurality of video segments. Wherein each video clip is a clip in the first video, and different video clips are not overlapped in time, and a plurality of divided video clips can form the first video.

Optionally, the video segmentation method may be segmentation according to images or sounds of the video; alternatively, the video may be divided equally by time, for example, after the user selects "divide equally by time" in the menu option 204 shown in fig. 2, a new menu option may be popped up to provide options of 2 equally dividing, 3 equally dividing, 4 equally dividing, 5 equally dividing, and after the user selects an option, the video may be divided equally by time into the selected number of equally dividing according to the selected number of equally dividing; alternatively, the user may set several division times in the video, and further divide the video into a plurality of video segments according to the division times, for example, after the user selects "custom division" as shown in the menu option 204 of fig. 2, a time axis may be displayed below the corresponding thumbnail, one division time may be set at a position along the time axis, and optionally, when the user clicks any position on the time axis, an image frame corresponding to the time in the video may be displayed in the display area of the thumbnail, so that the user can preview the specific image content of the video at the time.

The method is an automatic segmentation method, and the user does not need to set the segmentation time, but segments the video according to the characteristics of the video, such as image, sound, time and the like, so that the operation of manually selecting the segmentation time can be avoided, the efficiency is improved, and when the video is segmented based on the characteristics of the video, such as image, sound, time and the like, video segments different in background, character, scene and music can be obtained by fully utilizing the video characteristics, the segmentation purpose of the user is better met, a more precise video segmentation result can be obtained, and the condition that the segmentation time is set wrongly due to insufficient precision in operation when the segmentation time is manually selected is avoided.

Illustratively, as shown in fig. 3, when the step 102 is executed to divide the first video corresponding to the first thumbnail into a plurality of video segments, the following steps may be executed:

step 1021:

in the first video, the moment when the change of the image picture and/or the sound intensity of the adjacent frame reaches the preset condition is determined, and the segmentation moment is obtained.

The change of the image picture of the adjacent frame refers to the change of the image pictures of the two adjacent frames. Alternatively, the change of the image picture may be determined according to the pixel value of the image, for example, the change of the image may be a difference value of the average values of the pixel values of two adjacent frames of images.

Or, the change of the image frame may be comparing the scene, the object, and the background in two adjacent image frames, respectively, to determine the degree of the change, for example, on the basis of person (object) identification, it is identified that the persons in the two adjacent image frames are not the same person, which indicates that the change reaches a preset condition, and on the basis of background identification, it is identified that the difference value of the average values of the background colors of the two adjacent image frames exceeds a preset threshold, which determines that the preset condition is reached.

For example, as shown in fig. 3, when determining a time when the change of the image reaches a preset condition in the first video in step 1021 is performed, and obtaining the segmentation time, the following steps 1211 to 1213 may be performed:

step 1211:

executing preset image recognition processing aiming at the first video, wherein the preset image recognition processing comprises at least one processing mode of the following steps: object recognition, scene recognition, background recognition.

The object recognition, the scene recognition, and the background recognition may be performed by using an existing image recognition method, for example, an object and a background are recognized in an image frame by using an image threshold segmentation method, extracting an image contour, and the like, and an image recognition model for recognizing a scene is obtained by deep learning and a large amount of image training, which is not specifically limited in this embodiment of the present application.

Step 1212:

and determining adjacent image frames with changes of objects and/or scenes and/or backgrounds according to the recognition result of the preset image recognition processing.

After at least one of an object, a scene, and a background is identified in the image of the first video, two adjacent image frames in which a change exists are determined. For example: different people appear in the next frame; or if the person in the previous frame disappears in the next frame, determining that the objects in the two adjacent frames of images are different, and determining that the two adjacent frames of images have changes; alternatively, if it is recognized that the scene of the previous frame is indoors and the scene of the next frame is outdoors, it may be determined that the scenes of the two adjacent frames are not the same scene, that is, there is a change in the images of the two adjacent frames.

An alternative embodiment is: firstly, extracting a plurality of frames of images in a first video at preset intervals, and then respectively identifying objects and/or scenes and/or backgrounds of the extracted images of each frame. Then, comparing whether the object and/or scene and/or background of two frames of images close to each other in time changes or not according to the extraction sequence. If there is a change, a plurality of frames of images may be further extracted between the two extracted frames of images, and after performing the preset image recognition process, a further iterative determination may be made as to whether there is a change based on the recognition result. And if there is no change, no further identification of the image frame between the two extracted images is required. Through the comparison mode similar to the binary search method, the times of executing the preset image identification processing can be reduced, and the operation time and the occupied operation memory can be reduced.

Step 1213:

the segmentation instants are set according to the instants of adjacent image frames at which there is a change.

If a change in adjacent image frames is found, a split time may be set between two image frames. After all the adjacent image frames with changes in the first video are found, corresponding division time is set between every two adjacent image frames with changes.

Next, after performing step 1021, perform step 1022:

the first video is divided into a plurality of video segments based on the division time.

After the division time is obtained, the first video is divided into a plurality of video segments according to the division time. For example, for a 15-second first video, a first division time of 2 seconds, a second division time of 5 seconds, a third division time of 8 seconds, and a fourth division time of 14 seconds are obtained, and then the first video may be divided into a first video segment of 0-2 seconds, a second video segment of 2-5 seconds, a third video segment of 5-8 seconds, a fourth video segment of 8-14 seconds, and a fifth video segment of 14-15 seconds.

Optionally, in addition to setting the video segmentation time according to the image change of the video, the video segmentation time may also be set according to the sound intensity change. For example, a percentage threshold of sound intensity change may be preset, a value with the strongest sound intensity and a value with the weakest sound intensity in the video are found, a value obtained after difference is obtained is used as a maximum sound intensity difference value, then, a percentage value of a difference between sound intensities of every two adjacent sound sampling points and the maximum sound intensity difference value is calculated, if the percentage value exceeds the percentage threshold, a division time is set between the two sound sampling points, and if the percentage value does not exceed the percentage threshold, the division time is not set.

In the embodiment of the application, a plurality of video segmentation modes can be provided for a user to select. In this case, when the first input for the first thumbnail is received, a selection of a plurality of division methods by the user may be received, and the video may be divided according to the division method selected by the user. Therefore, multiple segmentation modes can be provided for a user, the user can conveniently select one segmentation mode for segmentation, and the operation efficiency is improved.

Accordingly, in this example, step 101 receiving a first input for a first thumbnail within a first region in a video editing page may include steps 1011 to 1013 as follows:

step 1011, receiving a seventh input for the first thumbnail;

step 1012, responding to a seventh input, and popping up and displaying a plurality of options for representing a plurality of segmentation modes;

step 1013, a first input for a first option of the plurality of options is received.

The first input and the seventh input may be operation inputs received through an interactive device such as a mouse, a keyboard, a touch screen, and the like, and a specific form of the operation inputs may be preset. For example, the seventh input may be a long press of a thumbnail, and as shown in fig. 2, after the user long presses the thumbnail in the first area, the seventh input is received based on the long press operation of the user, and in response to the seventh input, an option menu 204 of a plurality of options pops up at the upper right of the thumbnail, and the plurality of options displayed in the option menu 204 are respectively used for representing different dividing manners. When a user clicks one of the options, a first input for the option is received, and therefore, the segmentation mode selected by the user is determined to be the segmentation mode represented by the option clicked by the user.

Step 103:

and displaying a plurality of thumbnails corresponding to the video clips in a one-to-one manner in a second area of the video editing page.

And a second area for displaying thumbnails of the divided video clips. After the division into the plurality of video segments, you can generate a corresponding thumbnail for each video segment. The detailed implementation of the thumbnail generation manner may be performed as described in step 101, and is not described herein again. After obtaining a plurality of thumbnails corresponding to the plurality of video segments one by one, adding and displaying a plurality of thumbnails in the second area, and optionally adding a plurality of thumbnails behind the existing thumbnails. Optionally, any thumbnail of the received first input may be kept to display a thumbnail corresponding to an un-divided video in the original area, except that the thumbnail of the divided video segment is displayed in the second area.

When a plurality of thumbnails corresponding to a plurality of video segments are displayed, an interesting display effect can be provided for a user through a dynamic special effect, wherein the dynamic special effect can be displayed after a first operation is received, so that a dynamic interactive display effect can be provided within the processing time of dividing videos and generating thumbnails, and the user experience is improved. For example, the dynamic special effect may be that some fragmented image elements may be displayed around the screen and then aggregated to the location of the newly added thumbnails, thereby forming the thumbnails. The foregoing description is by way of example only and is not intended as a limitation upon the embodiments of the present application.

As an alternative example, as shown in fig. 3, step 103 may include displaying, in a second area of the video editing page, a plurality of thumbnails corresponding to the plurality of video segments one to one, and performing step 1031 as follows:

and displaying that the first thumbnail explodes into a plurality of fragments, and scattering the fragments into the second area to form a dynamic special effect of the thumbnails.

Step 104:

a second input is received for a second thumbnail within a second region.

The second input is used for indicating that the video segment corresponding to the thumbnail of which the second input is received is added to the third area, namely, the area added to the thumbnail of the candidate video segment for displaying the spliced video. The second input may be an operation input received through an interactive device such as a mouse, a keyboard, a touch screen, and the like, and a specific form of the operation input may be preset, for example, the user may touch the second thumbnail and drag the second thumbnail to the third area without lifting a finger, or the user may click the second thumbnail by an email, select an option of "add as a candidate video clip" in a pop-up right-click menu, and the like, which is not limited in this embodiment of the present application.

Step 105:

in response to a second input for a second thumbnail within the second region, the second thumbnail is displayed within a third region in the video editing page.

And the third area is used for displaying thumbnails of the candidate video clips of the spliced video. After receiving a second input for a second thumbnail within the second region, the second thumbnail is displayed within the third region. The original thumbnail in the third area can be kept unchanged, and a second thumbnail is added and displayed behind the original thumbnail in the third area. And the second thumbnail in the second area receiving the second input may still be displayed in the second area. Optionally, after the thumbnail image arbitrarily receiving the second input is added to the third area for display, the display may be still maintained in the original area.

Optionally, the first input and the second input received above may be received for a plurality of thumbnails at the same time. For example, the user may first select a plurality of thumbnails in the first area and/or the second area, and then perform the first input, which may indicate that the video or video segment corresponding to the selected plurality of thumbnails is to be divided. For another example, the user may select a plurality of thumbnails in the first area and/or the second area and then perform a second input, which may indicate that the selected plurality of thumbnails is to be added for display within the third area.

As an alternative example, after displaying the second thumbnail in the third area in the video editing page, the method may further include:

step 106, receiving a third input;

and step 107, responding to a third input, splicing the candidate video clips corresponding to all the thumbnails displayed in the third area to obtain a target video.

And the third input is used for indicating that the candidate video segments corresponding to all the thumbnails in the third area are spliced. The candidate video segment displayed in the third region is selected from the first region and/or the second region, and may include the original non-segmented video in the first region, or may include the segmented video segment in the second region.

Optionally, when the video/video clips in the third area are spliced, the splicing may be performed according to the display order in the third area. Specifically, before the third input is received at step 106, a fourth input for sorting the thumbnails within the third area may also be received. For example, the user may press any one of the thumbnails in the three areas for a long time to make each thumbnail in a draggable state, then release the finger, and then touch the thumbnail to be moved again to drag the thumbnail to a position to be dragged. The thumbnail dragging method in the above example may be applied to sorting in any one of the three areas, and may also be applied to an operation of dragging a thumbnail in any one of the areas to another area.

Furthermore, in response to a fourth input, the display order of the thumbnails in the third area may be sorted according to an instruction of the fourth input, and accordingly, when step 107 is executed to splice the candidate video segments corresponding to all the thumbnails displayed in the third area to obtain the target video, the candidate video segments corresponding to all the thumbnails may be spliced into the target video according to the display order of the thumbnails in the third area. Optionally, after the target video is spliced, the target video may be saved to a designated location (such as a local or network address), and then, three areas in the video editing page may not be cleared, and the current video/video clip/candidate video clip is still retained, so that the user may enter into the next video splicing by using the current content.

In a specific embodiment, the video in the first area is added to the third area, before the third input is received in step 106, the following steps 108 and 109 are performed:

step 108, receiving a fifth input aiming at a third thumbnail in the first area;

the fifth input is for indicating that the video corresponding to the thumbnail image for which the second input was received is added to the third area. The fifth input is similar to the second input and will not be described in detail herein. Alternatively, the fifth input may operate the same as the second input.

And step 109, responding to a fifth input, and displaying a third thumbnail in the third area.

Step 109 may be similar to step 105, and reference may be made to the description of step 105, which is not repeated herein.

Further, the video or video segment corresponding to the thumbnail displayed in the second area or the third area can still be continuously divided. It should be noted that, if the video or the video segment corresponding to the thumbnail in the third area has already been split, even if the indication of splitting is received, the splitting may not be continued, and optionally, in an example, if a different splitting manner is selected, the video or the video segment that has been split in the third area may be re-split according to the different splitting manner, and the result is put into the second area.

As an alternative example, prior to receiving the second input for the second thumbnail within the second area, a sixth input for a third thumbnail may also be received. And the third thumbnail is one of the thumbnails displayed in the second area or the third area. Then, in response to a sixth input, the video or video segment corresponding to the third thumbnail is divided into a plurality of video segments. Then, in the second area, a plurality of thumbnails corresponding to the video corresponding to the third thumbnail or a plurality of video segments divided from the video segment are displayed.

In the embodiment of the application, the video editing page is divided into three areas, wherein the first area is used for displaying the thumbnail of the original video material, the second area is used for displaying the thumbnail of the divided video clip, and the third area is used for displaying the thumbnail of the candidate video clip of the spliced video, so that the input of the division and the splicing of the video can be integrated into the same video editing page for input.

When the user edits the video, the video segment obtained by dividing the original material in the first area can be added to the second area, and the video segment in the second area can be added to the third area. In some alternative examples, the original video material that was not segmented within the first region may be placed directly into the third region. In other alternative examples, the video segment in the second area or the video/video segment in the third area may be further segmented, and the segmentation result may be placed in the second area. In other examples, videos of candidate video segments in the third area that are not intended to be used as the stitched video may also be deleted, wherein if the thumbnails in the original area continue to remain after the thumbnails in the first area or the second area are added to the third area, the unneeded candidate video segments may be deleted directly in the third area; if the thumbnail in the first area or the second area is added to the third area, the thumbnail in the original area is not retained, that is, in the case that the thumbnail in the first area or the second area is moved to the third area, the thumbnail of the candidate video segment that is not needed in the third area can be moved back to the original area.

Like this, through the linkage operation to the thumbnail that contracts in the three region, the operation of cutting apart and splicing a plurality of videos that the user can be convenient, the operation mode is nimble, has simplified the input of video editing greatly, has solved the loaded down with trivial details problem of video editing input.

Optionally, the video editing method provided in this embodiment of the present application may control the electronic device to execute through application software installed in the electronic device, for example, APP (application program) in the mobile phone, an input system component in the mobile phone, application software in the computer, and the like.
