Detailed Description

In the description of the embodiments of the present application, unless otherwise indicated, "at least one" means one or more, and "a plurality" means two or more. In addition, in order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", and the like are used to distinguish the same item or similar items having substantially the same function and effect. It will be appreciated by those of skill in the art that the terms first, second, etc. do not denote any limitation of quantity or order of execution, and that the terms first, second, etc. do not denote necessarily different. In addition, in the description of the embodiments of the present application, unless otherwise stated, the positions and the forms of the interface elements in the interface schematic diagrams are all schematic, and in actual implementation, the positions and the forms can be flexibly adjusted according to actual requirements.

The embodiment of the application provides a video processing method which can be applied to a scene of previewing a shot video in electronic equipment. For example, the electronic device in the embodiments of the present application may be a device such as a mobile phone, a tablet computer, a desktop, a laptop, a handheld computer, a notebook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook, a cellular phone, a personal digital assistant (personal digital assistant, PDA), an augmented reality (augmented reality, AR) \virtual reality (VR) device, and the specific form of the electronic device is not limited in the embodiments of the present application. In the following embodiments, the electronic device is mainly taken as an example of a mobile phone, to describe the solution of the present application.

In some embodiments, the mobile phone may capture a video to be previewed in a single-mirror video mode. The single-lens video recording mode is a common video recording mode in a conventional sense, and in the single-lens video recording mode, the mobile phone only adopts one camera to shoot video. For example, the interface 101 shown in fig. 1A (a) is a view interface before recording in a single-mirror recording mode. Only the image 102 captured by a single camera (e.g., front camera) is included in the interface 101.

In other embodiments, the mobile phone may capture a video to be previewed in a multi-mirror video mode. In the multi-lens video recording mode, the mobile phone can adopt two or more cameras to shoot videos at the same time. For example, the interface 103 shown in fig. 1A (b) is a view interface before recording in a multi-mirror recording mode. The interface 103 includes an image 104 and an image 105 acquired by two cameras (e.g., a rear main camera and a front camera). In the following embodiments, a multi-mirror video recording mode will be mainly used as an example to describe the present application.

It should be noted that in the multi-lens video recording mode, the mobile phone may also be triggered to switch to capturing video with a single camera by a switching operation, for example, clicking a switch button 106 in the interface 103. In order to distinguish from a single-mirror video mode, a scene of a video shot by a single camera in a multi-mirror video mode can be recorded as a multi-mirror mode.

In one scenario, the handset may take a video to be previewed with the effect template selected (which may be denoted as template 1). Each effect template corresponds to a group of video effects, and each group of video effects is formed by combining a plurality of effects of background music, a filter, special effects (such as flashing stars), transition, photo frames, stickers, tail pieces and the like. The template 1 is selected before the video shooting, and the mobile phone can shoot the video by adopting the template 1. For convenience of explanation, the template 1 may be referred to as a first template, and a set of video effects corresponding to the template 1 may be referred to as a first video effect.

Illustratively, control 1 is included in the viewfinder interface before the multi-view video mode video recording, for example, control 1 is a "micro movie" button 107 in interface 103 shown in fig. 1A (b). The control 1 is used for triggering the mobile phone to select an effect template. The mobile phone can receive clicking operation or long-press operation of the control 1 by a user. In response to a click operation or a long press operation of the control 1 by the user, a plurality of template options may be displayed. For example, in response to a user clicking on the "micro movie" button 107 (i.e., control 1) shown in fig. 1A (B), the cell phone may display the interface 111 shown in fig. 1B (a), where the interface 111 includes a plurality of template options (shown in the dashed box), such as "hello summer", "good time", "good mood", "light weekend", and the like. Wherein, a plurality of template options correspond to a plurality of effect templates one by one. The plurality of template options may be used to trigger a handset to select an effect template. The handset may receive a user selection of any template option (which may be referred to as option 1, also referred to as a first option). In response to the user selecting the option 1, the mobile phone may select an effect template (which may be referred to as a template 1) corresponding to the option 1. It should be appreciated that the handset may default to selecting the effect template corresponding to the first template option. For example, the default selected by the handset is the template corresponding to the "hello summer" option shown in (a) of fig. 1B. Also, a control 2 is included in an interface (which may be referred to as an interface 1, or may be referred to as a fourth interface) that displays a plurality of template options, and for example, the control 2 is a button 112 in an interface 111 shown in fig. 1B (a). The control 2 is used for triggering the mobile phone to shoot videos.

In some embodiments, after the template 1 is selected, the mobile phone may receive a click operation, a long press operation, or a sliding operation (may also be referred to as a fourth operation) of the control 2 by a user, which will be mainly described below in terms of the click operation. In response to a click operation of the control 2 by the user, the mobile phone may display a shooting preparation interface (may be denoted as interface 2, and may also be referred to as a first interface). In the process of displaying the interface 2, the user can finish the preparation work before shooting such as adjusting the shooting angle, turning on or off the background music of the template 1, and the like. For example, the interface 2 is an interface 113 shown in (B) of fig. 1B, and the interface 113 does not include a shooting timer, a control for ending shooting, suspending shooting, or the like, that is, it indicates that shooting has not been started. Also, a control 3 is included in the interface 2, such as a button 114 in the interface 113 shown in (B) in fig. 1B.

Further, after the interface 2 is displayed, the mobile phone may receive operations (may also be referred to as a first operation) such as a click operation, a long press operation, or a sliding operation of the control 3 by a user. The clicking operation will be mainly described hereinafter. In response to a click operation of the control 3 by the user, the mobile phone may start video capturing using the template 1 and display a view interface (which may be referred to as an interface 3 or may be referred to as a second interface) in capturing. For example, interface 3 is interface 115 shown in (c) of fig. 1B. The interface 115 includes interface elements such as a photographing time period 00:00, an end photographing button 116, a pause photographing button 117, and the like, which indicate that video photographing has started.

In other embodiments, the mobile phone may receive a click operation of the control 2 from the user after selecting the template 1. In response to a click operation of the control 2 by the user, the mobile phone can directly display the interface 3. That is, the interface 2 is not displayed, but the shooting is directly entered.

After starting the video capture, the handset may end the video capture in response to event 1.

In some embodiments, an end recording control is included in interface 3, such as end capture button 116 shown in fig. 1B (c), for triggering the cell phone to end video capture. Event 1 may be a click operation or a long press operation of the user on the end recording control, etc.

In other embodiments, the template 1 has a dailies in which the effect of sheeting that can be obtained after photographing using the template 1 is present. For example, filters, background music, etc. Further, in order to ensure that the sheeting formed after photographing using the template 1 can be kept highly consistent with the dailies, namely: the final sheeting results are seen by the user from the dailies. After the mobile phone selects the template 1, the mobile phone needs to control the duration of shooting the video, so that the duration of forming a slice by using the template 1 finally is the same as the duration of a sample slice of the template 1 (also can be called as a first duration). That is, the template 1 may indicate a video that is longest shot for a certain period of time (may be noted as a preset period of time).

In a specific implementation, the preset duration is the same as the sample duration. For example, if the template 1 is "hello summer" and the duration of the sample of "hello summer" is 15s, after the template of "hello summer" is selected and shooting is started, the longest shooting can be controlled to obtain a video of 15 s.

In another specific implementation manner, the video effect corresponding to the template 1 includes a tail (also referred to as a first tail), where the tail is a fixed content, such as an animation of a logo (logo) of a mobile phone manufacturer, and is irrelevant to the content photographed at this time. Accordingly, when a video effect is added to a photographed video using the template 1, a trailer is added at the end. In this case, the sum of the preset time period and the end-of-chip time period (which may also be referred to as the second time period) is equal to the sample time period, that is, the preset time period is equal to the difference between the sample time period and the end-of-chip time period. For example, if the template 1 is "hello summer", and the duration of the sample in the "hello summer" is 15s, and the corresponding video effect of the template 1 includes 1s tail, the predicted duration is (15-1) s=14s, and the interface 115 shown in (c) in fig. 1B includes 00:14, which is used for indicating that the preset duration is 14s.

It should be understood that the above manner of indicating the preset time period by the sample wafer of the template 1 is only an alternative manner, and is not limited to this in practical implementation. For example, the preset time period may also be indicated by the time period of the background music of the template 1, so that the formed piece cannot exceed the time period of the background music.

In this embodiment, the event 1 may be an event in which a shooting duration (may also be referred to as a recording duration) is equal to a preset duration. In the following embodiments, the present application will be mainly described by taking an example in which the shooting duration of event 1 is equal to the preset duration.

For example, taking the current shooting duration as the duration 00:14 on the left side of "/" in the dashed line box in the interface 121 shown in (a) in fig. 1C, the preset duration is the duration 00:14 on the right side of "/" in the dashed line box in the interface 121 shown in (a) in fig. 1C as an example, that is, the shooting duration is equal to the preset duration, and all the shooting durations are 14s, when event 1 is satisfied, the mobile phone may end shooting.

After the shooting is finished, the mobile phone can form a slice with the video effect indicated by the template 1. That is, after the template 1 is selected, the mobile phone can take the video with the template 1, so as to obtain a slice with the video effect indicated by the template 1. Wherein, adopt template 1 to shoot the video includes: in the process of shooting video, the mobile phone adds an effect to the acquired image in real time according to the video effect indicated by the template 1 and displays the effect in a view finding interface, for example, a filter, a sticker, background music and the like can be added in real time. And/or capturing video using template 1 includes: after the video shooting is finished, the mobile phone performs post-processing on the shot video according to the template 1, and a video effect is added. In a specific implementation manner, effects such as background music, a filter, a sticker, a photo frame and the like can be added in real time in the shooting process, and effects such as transition, tail and the like can be added after shooting is finished.

After forming the sheeting (which may also be referred to as a first sheeting), the handset may display a preview interface (which may also be referred to as a third interface) for the sheeting. In the preview interface, the effect of the sheeting can be previewed. For example, the preview interface is the interface 122 shown in (b) of fig. 1C, and the formed piece can be played in the interface 122. The flakes in interface 122 have the effect of a light grey filter, a decal of "summer feelings, most beautiful summer we together" and the like.

In addition, in the preview interface, the mobile phone can edit the film. That is, the preview interface can also be understood as a sheeted editing interface. After the preview interface is displayed, the mobile phone can receive a preset operation of a user, wherein the preset operation is used for triggering the mobile phone to edit and adjust the effect of the film. For example, edit the effects of background music, filters, special effects (e.g., blinking stars), transitions, photo frames, stickers, and footage, etc. that adjust to the film. The specific implementation of editing will be described in the following detailed examples, which will not be described in any great detail here.

In this embodiment of the present application, the mobile phone may display the preview interface in response to an event (such as event 1) for ending video capturing. Specifically, after ending the video capture, the camera application may invoke the video editing application to display the preview interface. That is, while the preview interface is displayed, the camera application is still running in the foreground.

In the video shooting and previewing scene, if the mobile phone exits from running the camera application in the foreground and exits from the main interface of the mobile phone in the process of displaying the previewing interface, the video processing method provided by the embodiment of the application exits from the previewing interface. Thereby interrupting video editing. Subsequently, the mobile phone may receive a click operation of the camera icon (may also be referred to as a first icon) in the main interface by the user, where the click operation is used to trigger the mobile phone to run the camera application in the foreground. Responding to clicking operation of a camera icon in a main interface by a user, and if a camera application still exists in the background of the mobile phone, namely: the camera application is not cleaned, and the mobile phone can resume displaying the preview interface again. So that editing of the video in the preview interface can continue.

In summary, by adopting the method of the embodiment of the present application, after exiting the preview interface, when the clicking operation of the application icon of the camera application by the user is detected again, the mobile phone can resume displaying the preview interface, so as to facilitate the continuous preview and editing of the video. Therefore, the loss of editing data can be avoided, and the man-machine interaction efficiency in the editing process is improved.

Referring to fig. 3, a partial software structure block diagram of a mobile phone is provided in an embodiment of the present application. The software system of the mobile phone can adopt a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture or a cloud architecture. In the embodiment of the application, a layered Android (Android) system is taken as an example, and a software structure of a mobile phone is illustrated. The layered architecture may divide the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the android system is divided into four layers, from top to bottom, an application layer (abbreviated as application layer), an application framework layer (abbreviated as framework layer), a hardware abstraction layer (hardware abstract layer, HAL) layer, and a Kernel layer (Kernel, also referred to as driver layer).

In the embodiments of the present application, an application layer and an application framework layer closely related to a method for implementing the embodiments of the present application are mainly described in more detail. As shown in fig. 3, an application layer 310 and an application framework layer 320 are included in the layered architecture.

Among other things, the application layer 310 includes a desktop application 311, a camera application 312, and a video editing application 313.

The desktop application 311 may be used to display icons of a plurality of applications in a mobile phone, such as application icons of applications in a camera application, gallery application, calendar application, conversation application, map application, music application, video application, short message application, and the like. Desktop application 311 may also be used to receive various user operations on the main interface. For example, the desktop application 311 may receive a user click, long press, etc. of an application icon. It should be appreciated that the main interface of the handset belongs to the desktop application 311.

The camera application 312 includes a plurality of photographing modules, such as a general photographing module, a portrait module, a general video module, a multi-mirror video module, and the like. The multi-mirror video module further comprises a micro-film module. Illustratively, the "micro-movie" button 107 in the interface 103 shown in (b) of FIG. 1A may trigger the invocation of the micro-movie module. After invoking the micro-movie module, an effect template may then be selected before capturing and then the video may be captured using the selected effect template. Still further, the micro-movie module may include a one-click module and a segmentation module (not shown). The one-key shooting module provides a one-key shooting function, and the mobile phone can shoot once to obtain a piece with a corresponding video effect after selecting the effect template by adopting the one-key shooting function. For example, the above examples of fig. 1B and 1C are one-click functions. The segmentation shooting module provides a segmentation shooting function, and the mobile phone can finally form a piece with a corresponding video effect by shooting multiple sections of video after selecting an effect template by adopting the segmentation shooting function. In the following embodiments, the embodiments of the present application will be mainly described by taking a one-click function as an example.

Video editing application 313 is a built-in application of the cell phone that can be used for video preview and editing. Different from the camera application, gallery application, etc., applications are: in the handset, there is no physical portal for the video editing application. For example, there is no application icon for the video editing application on the main interface. Video editing applications can typically only be invoked by camera applications, gallery applications, for video previews and editing. That is, the portals of the video editing applications are camera applications and gallery applications.

Video editing application 313 may be understood as the editing application described previously. Video editing 313 a film preview module is included in the video editing application 313. In some embodiments, after capturing the video using the one-click function is completed, the handset may invoke a tile preview module in video editing application 313 of video editing application 313 to display the preview. Illustratively, the preview interface in the foregoing, interface 122 as shown in (b) in fig. 1C, is displayed by camera application 312 after invoking the film preview module of video editing application 313 of video editing 313.

The video editing application 313 further includes a protocol confirmation module, where the protocol confirmation module is configured to confirm whether the user agrees with the relevant protocol of the video editing application 313 when the mobile phone invokes the video editing application 313 for the first time. That is, the protocol validation module is typically only used when the video editing application 313 is first invoked.

Also included in video editing application 313 in this embodiment are an onPause (onPause) interface and an onResume (onResume) interface. The page onPause interface may be invoked so that the interface exit is not destroyed after foreground display. Thereby facilitating the restoration of the display of the interface when the corresponding application is run again in the foreground. In some embodiments, as shown in FIG. 3, when returning from the preview interface to the main interface, the page onPause interface may be invoked to effect that the preview interface is not destroyed after exiting to display the preview interface in the foreground. Thereby facilitating quick resumption of the preview interface upon reentry of the camera application.

The page onResume interface may be invoked so that the interface that is not destroyed in the background may be displayed in the foreground again so that the user may interact again. In some embodiments, as shown in fig. 3, after the preview interface exits the foreground display, when the clicking operation of the camera icon by the user is detected again, the page onResume interface may be invoked, so as to implement that the preview interface may be quickly restored after the camera application is re-entered.

And, the application framework layer 320 includes an activity manager 321 and a view system 322.

The activity manager 321 may be used to manage the lifecycle of pages in the handset. In some embodiments, as shown in FIG. 3, the page onPause interface, the page onResume interface, and the tile preview module may all interact with the activity manager 321 to enable management of the lifecycle of the preview interface.

View system 322 may be used to build a display interface for an application. Each display interface may be composed of one or more controls. In general, controls may include interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets (widgets), and the like. In some embodiments, as shown in FIG. 3, the view system 322 may perform interface rendering, display, such as rendering and displaying a preview interface, according to the lifecycle of the page.

The video processing method of the embodiment of the application can be implemented in the mobile phone with the hardware structure and the software structure. Specifically, as shown in fig. 4, the method in the embodiment of the present application includes:

s401, the camera application 312 receives the start request.

Illustratively, when the camera application 312 receives a click operation of a camera icon in the main interface from a user, a start request is received. Alternatively, the camera application 312 may receive a user click on a camera task in the multi-task interface, or may receive a start request.

S402, the camera application 312 runs in the foreground, and then starts a one-touch function based on a user operation.

The camera application 312 may be launched and run in the foreground in response to the launch request. Then, after passing through (B) in fig. 1A, (a) in fig. 1B, (B) in fig. 1B, and (c) in fig. 1B in this order, a one-touch function may be activated.

S403, the camera application 312 ends the video capturing in response to event 1.

For event 1, reference may be made to the foregoing description, and the description is omitted here.

For example, taking the recording duration corresponding to the template 1, that is, the preset duration is 14s as an example, if the current shooting duration reaches 14s, the event 1 is satisfied and the current shooting duration is equal to the preset duration, at this time, the video shooting can be ended.

S404, the camera application 312 sends a call request to the video editing application 313.

In the present embodiment, the camera application 312 invokes the video editing application 313 to display a preview interface of the sheeting. For the preview interface, see also the description above, and the description is omitted here.

It should be noted that during use of the handset, the user is required to agree with the relevant user protocols of the video editing application 313 when the video editing application 313 is first invoked. Based on this, in some embodiments, video editing application 313 responds to the invocation request, and if it determines to invoke for the first time, video editing application 313 (e.g., protocol validation module) displays the user protocol and provides options for the user to choose whether to agree or not. The video editing application 313 may continue to execute S405 in response to the user agreeing to the user agreement. Otherwise, video editing application 313 returns to display interface 1 in response to the user disagreeing with the user agreement. I.e. an interface comprising a plurality of template options.

S405, the video editing application 313 displays a preview interface.

That is, in the embodiment of the present application, the video editing application 313 is invoked in the camera application 312 to display the preview interface. For example, the preview interface is interface 122 shown in (b) of fig. 1C.

In some embodiments, after displaying the preview interface, if the preset condition is met, the video editing application 313 may display a prompt 1 (may also be referred to as a first prompt) in the preview interface, such as a prompt 505 in the interface 501 shown in fig. 5, where the specific content of the prompt 505 is "click attempt different film styles". The prompt message 1 is used for prompting the effect of switching to the slice. Wherein, meeting the preset condition includes: the display duration of the preview interface reaches a first duration, e.g., 10s, and the video editing application 313 does not detect a preset operation by the user. Or, the preview interface may be played as a slice, and satisfying the preset condition includes: the clip playback ends, and the video editing application 313 does not detect a preset operation by the user. The preset operation is used for triggering the mobile phone to switch into the tablet effect.

The preview interface includes an effect switching control, which is used to trigger the mobile phone to switch to the effect of the film. For example, the effect switching control may include a style switching control, such as a "style" button 502 in the interface 501 shown in fig. 5, for triggering the mobile phone to switch into a style of a slice, where a style refers to an overall effect of the video effect of the template 1, such as an overall effect of multiple effects of a filter, a sticker, a photo frame, and the like, except for background music. For another example, the effect switch control may include a music switch control, such as a music button 503 in the interface 501 shown in fig. 5, for triggering the handset to switch to background music for a piece. For another example, the effect switch controls may include edit controls, such as edit buttons 504 in interface 501 shown in fig. 5, for triggering the cell phone to switch to various effects such as background music, filters, stickers, photo frames, volume, etc. The preset operation may be a click operation or a long press operation of the effect switching control by the user.

Further, the absence of detection of the preset operation by the user means that: starting from the first use of the mobile phone, in a scene of shooting a video by selecting an effect template, after shooting is completed and entering a preview interface, a user input preset operation is never detected. For example, in the process of using the mobile phone in history, after the video is shot by the user selecting the effect template, clicking the style switching control in the preview interface, and when the preview interface is displayed this time, displaying no prompt message 3 after the completion of the film playing. In this way, repeated prompts to the user who is well known for the function of effect switching can be avoided.

In some embodiments, after displaying the preview interface, the video editing application 313 may receive a preset operation of the user for switching to the effect of the tile. For the preset operation, reference may be made to the description in the foregoing embodiments, which is not repeated here. For example, the preset operation may be a click operation of the music button 602 in the interface 601 shown in (a) of fig. 6A by the user. In response to the preset operation, the video editing application 313 may display a plurality of effect options in the preview interface, such as 4 music options of "eased", "summer", "dynamic", "pleasant" in the pop-up window 603 shown in (b 1) in fig. 6A, one for each background music.

The specific implementation of the effect of switching to a slice will be described below mainly taking the switching of background music as an example.

In one particular implementation, multiple background music may be saved in video editing application 313, and each background music has two versions of duration, version 1 duration being the template duration of the effect template that the background music matches. The duration of version 2 is a fixed duration, such as 30s. And the fixed duration (e.g., 30 s) is longer than or equal to the longest template duration (e.g., 20 s). For example, the version of background music stored in the video editing application 313 and its matching effect templates are shown in table 1 below:

TABLE 1

In the present implementation, in response to a preset operation, the video editing application 313 may display a plurality of music options. The plurality of music options includes a first music option and a second music option. Wherein the first music option corresponds to background music (noted as music 1) of matching template 1 and the first music option corresponds to music 1 of version 1. The first music option is typically only one. The second music option corresponds to background music (noted as music 2) that matches other templates (templates other than template 1), and the second music option corresponds to music 2 of version 2. The second music option may typically be plural, such as at least 3. In this way, music sufficient to satisfy the duration of the pieces formed with the template 1 can be provided to the user selection quickly.

For example, table 1 above is an example, if the template 1 selected before shooting is "hello summer", the first music option may be a plurality of pieces of comfort music corresponding to 15s version, and the second music option may be a plurality of pieces of comfort music corresponding to 30s version, dynamic music corresponding to 30s version, pleasant music corresponding to 30s version, careless music corresponding to 30s version, winter music corresponding to 30s version, and the like. For example, the video editing application 313 may display a pop-up window 603 shown in (b 1) in fig. 6A, where the pop-up window 603 includes 15s of the option of soothing music (i.e., the first music option) and 30s of summer music, 30s of dynamic music, 30s of pleasant music (i.e., the second music option). The template duration of "hello summer" is the music duration of the soothing music of version 1, namely 15s, and correspondingly, the duration of the piece formed by "hello summer" is usually not more than 15s. Therefore, the length of music corresponding to the plurality of music options in the pop-up window 603 shown in (b 1) of fig. 6A can satisfy the entire piece.

In another specific implementation, a plurality of background music, each including version 1, is also stored in video editing application 313, see in particular table 1. In the present implementation, in response to a preset operation, the video editing application 313 may display a plurality of music options. The plurality of music options includes a first music option and a second music option. Wherein the first music option corresponds to background music (noted as music 1) of matching template 1 and the first music option corresponds to music 1 of version 1. The first music option is typically only one. The second music option corresponds to the background music (denoted as music 3) matching template 2, the template duration of template 2 being longer than or equal to the template duration of template 1. In the following embodiments, description will be mainly given by taking an example in which the template duration of the template 2 is equal to the template duration of the template 1. Since the music duration of the background music of the version 1 is the same as the template duration of the matched effect template, the template duration of the template 2 is equal to the template duration of the template 1 and can be also understood as: the music duration of music 3 of version 1 is equal to the music duration of music 1 of version 1. And the second music option corresponds to music 3 of version 1. The second music options may be one or more. In this way, the video editing application 313 can provide the user with music that most coincides with the clip duration of the clip, so that operations such as deletion of music at the time of switching and fade processing for the end can be reduced.

For example, still for example, table 1 above, if template 1 selected prior to shooting is "hello summer", then the first music option corresponds to 15s version (i.e., version 1) of soothing music. The second music option may correspond to one or more of 15s version of summer music, 15s version of dynamic music, 15s version of happy music. For example, video editing application 313 may display a pop-up window 604 shown in (b 2) of fig. 6A, where pop-up window 604 includes a 15s version of the option of soothing music (i.e., the first music option) and a 15s version of summer music, a 15s version of dynamic music, a 15s version of pleasant music (i.e., the second music option).

It should be understood that the above two specific implementations are only typical alternatives for determining music options, and are not limited to these implementations. For example, the two specific implementations may be combined, and the option corresponding to the music 3 of the version 1 is first determined to be the second option. If music 3 is not present, or the number of music 3 is insufficient, video editing application 313 may further append the second option with music 2 corresponding to version 2.

In the foregoing description of the music options, the covers and names of the music options are not associated with the corresponding effect templates in order to distinguish between the music and effect templates. In other embodiments, to reflect the association of music and effect templates, when multiple music options are displayed, the cover of the music option may be set to the template cover of the corresponding music-matched effect template, e.g., the cover of the first music option is set to the cover of template 1. Alternatively, the name of the music may be set to the template name of the corresponding music-matched effect template, for example, template 1 is "hello summer", and the name of the first music option may be set to "hello summer".

In some embodiments, after the plurality of music options are displayed, the first music option may be selected by default. For example, if the 15s soothing music option shown in (b 1) of fig. 6A is the first music option, the first option is bolded to indicate that the 15s version of soothing music is currently selected.

In some embodiments, after displaying the plurality of music options, video editing application 313 may receive a user selection operation of any of the music options (which may be denoted as music option 1). In response to the selection operation of music option 1, the mobile phone can replace the background music in the clip with the background music corresponding to option 1 and play the clip from the beginning. Illustratively, taking the example where music option 1 is option 611 shown in (a) in fig. 6B, video editing application 313, in response to a user's selection operation of option 611, may replace the background music in the clip with the music corresponding to option 611, and then play the clip from scratch. In this way, it is possible to facilitate previewing the effect of applying the selected music to the film. Further, if the music duration of the music corresponding to the music option 1 is longer than the slicing duration, the music piece with the same duration as the slicing duration may be cut from the beginning of the music corresponding to the option 1, and the end of the cut music piece may be subjected to the fade treatment.

Subsequently, the mobile phone may receive operation 1 of the user, where operation 1 is used to trigger the mobile phone to switch the background music. Wherein operation 1 may be a slide down operation from top to bottom from a pop-up window (which may be referred to as a music pop-up window) displaying a plurality of music options. Or, the music popup window comprises a confirmation control, and the operation 1 can be a click operation or a long-press operation of the confirmation control by a user. For example, the music pop-up window is a pop-up window 612 shown in (B) in fig. 6B, and a "v" button is included in the pop-up window 612. The ". V" button is a confirmation control. Operation 6 may be a click operation of a "v" button by a user. The form of operation 1 is not particularly limited in the embodiment of the present application. In response to operation 1, the handset may close the plurality of music options and resume displaying the preview interface that does not include the music options. For example, the interface 601 shown in (a) in fig. 6A may be displayed.

In the above-described embodiment, the video editing application 313 can switch to an effect of a film, such as switching background music, in response to a preset operation, so that a fixed combination of effects such as background music, a filter, a photo frame, a sticker, etc., in an effect template (e.g., template 1) selected before shooting can be broken. For example, after the background music is switched, the filter, photo frame, sticker, etc. of the template 1 may be combined with the switched background music. Thus, the diversity of the sheeting effect can be improved.

During the display of the preview interface, the user may enter an operation to return to the main interface, resulting in interruption of the preview. In this embodiment of the present application, in response to the operation of returning to the main interface, not only the main interface may be displayed, as described in detail in S406 below, but also the preview interface may be controlled to enter a pause state, as described in detail in S407-S408 below.

S406, the desktop application 311 responds to the operation of returning to the main interface and displays the main interface.

The operation of returning to the desktop may be a user sliding up operation from the bottom of the preview interface. Alternatively, the return to desktop operation may be a user click operation on a preset control (e.g., home key) hovering in the screen. In the following embodiments, a user's up-slide operation from the bottom of the preview interface will be mainly described as an example. For convenience of explanation, the operation of returning to the main interface may be referred to as a second operation.

Illustratively, the preview interface is an interface 701 shown in (a) of fig. 7, and the desktop application 311 may display an interface 702 shown in (b) of fig. 7 in response to a user's upward slide operation from the bottom of the interface 701. Interface 702 is the main interface of the handset.

S407, the video editing application 313 transmits a call request to the activity manager 321 in response to the operation of returning to the main interface.

Video editing application 313 (e.g., page onPause interface) sends a call request to campaign manager 321 to request that the preview interface not be destroyed after exiting the preview interface.

It should be noted here that video editing application 313 (e.g., the page onPause interface) simply provides a portal that can control the preview interface to enter a pause state. And video editing application 313 (e.g., the page onPause interface) needs to call activity manager 321 to implement state management after entering the background for the preview interface.

It should be noted that the foregoing S407 and S408 do not have absolute sequential timing. For example, S406 and S407 may be performed simultaneously. For another example, S407 may be performed first, and S406 may be performed later. The embodiment of the present application is not particularly limited thereto.

S408, the activity manager 321 controls the preview interface to enter a pause state and stores data of the preview interface.

The pause state (may also be referred to as a first state) is an onPause state. After the preview interface enters a pause state, the preview interface is not destroyed even if the preview interface is currently covered by the main interface, i.e. the preview interface is not displayed in the foreground.

And, the data of the preview interface includes content displayed in the interface. In some embodiments, the data of the preview interface also includes editing data generated at the preview interface, such as switched background music, style, etc. So that all the operations of the user on the sheeting can be recorded.

S409, the desktop application 311 receives a click operation of the camera icon by the user.

After returning to the main interface of the mobile phone, the user may click on the camera icon to trigger the mobile phone to run the camera application in the foreground again. For example, the user clicking on the camera icon 802 in the interface 801 shown in fig. 8 (a) may trigger the handset to run the camera application 312 again in the foreground.

S410, the desktop application 311 sends a start request to the camera application 312.

S411, the camera application 312 inquires whether the background process thereof is destroyed.

If the background process of the camera application 312 is not destroyed, it indicates that the camera application 312 is still in the background. Accordingly, the call relationship (also referred to as call stack) that camera application 312 calls video editing application 313 to display the preview interface also remains. For this case, the embodiment of the present application executes S412 to restore the preview interface.

If the background process of the camera application 312 has been destroyed, it indicates that the camera application 312 has been cleaned up from the background. Accordingly, the calling relationship of camera application 312 calling video editing application 313 to display the preview interface does not exist. In this case, the calling relationship cannot be obtained, and the camera application 312 is only initialized when started, and an interface initialized by the camera application 312, such as a view finding interface before photographing, is displayed. For example, in response to a clicking operation of the camera icon 802 in the interface 801 shown in fig. 8 (a), if it is queried that the camera application 312 has been destroyed, the camera application 312 may display the interface 803 shown in fig. 8 (b 1), where the interface 803 is a view interface before photographing, and is an interface initialized by the camera application 312. It should be noted that the word "camera application destroyed" in the interface 803 shown in (b 1) in fig. 8 is merely for illustration, and is not normally displayed on the interface in practice.

S412, the camera application 312 sends a call request to the video editing application 313 in response to the background process not being destroyed.

In this embodiment, the background process of the camera application 312 is not destroyed, and the camera application 312 may query the call relationship of the camera application 312 to call the video editing application 313, and then the camera application 312 may call the video editing application 313 (such as the page onResume interface) according to the call relationship to request to display the preview interface.

S413, the video editing application 313 transmits a call request to the activity manager 321.

The video editing application 313 (e.g., page onResume interface) further sends a call request to the activity manager 321 in response to the call request of the camera application 312 to request restoration of the preview interface.

S414, the activity manager 321 controls the preview interface to enter a recovery state from a pause state, and recovers the data of the preview interface.

The recovery state (may also be referred to as a second state) is an onResume state. And after the preview interface enters the recovery state, indicating that the preview interface is in a state of being displayed in the foreground.

It should be appreciated that the activity manager 321, when restoring the preview interface, needs to invoke the capabilities of the view system 322 to render and display.

S415, the activity manager 321 transmits the restored preview interface to the video editing application 313.

S416, the video editing application 313 resumes displaying the preview interface.

Illustratively, in response to a user clicking on the camera icon 802 in the interface 801 shown in fig. 8 (a), if it is queried that the camera application is not destroyed, the video editing application 313 may display the interface 804 shown in fig. 8 (b 2), which interface 804 is a preview interface of a clip. It should be noted that the word "camera application is not destroyed" in the interface 803 shown in (b 2) in fig. 8 is merely for illustration, and is not normally displayed on the interface in practice.

After resuming the display of the preview interface, the video editing application 313 may continue to switch to the effect of the tile in response to the preset operation by the user. For a specific implementation of the effect of switching to the slice, reference may be made to the description of the foregoing S405, and the description thereof will not be repeated here.

It can be seen that, in the above S403-S416, in the scenario where the camera application 312 invokes the video editing application 313 to display the preview interface after the video capturing is finished, if the camera application 312 exits to the background of the mobile phone, it is triggered to run in the foreground again through the camera icon in the main interface, and the video editing application 313 can resume displaying the preview interface.

Compared with the conventional technology, in the process of using the system applications such as the camera, the gallery, the setting, the contact person and the like in the mobile phone, the method returns to the main interface of the mobile phone, and after that, when the application icon on the main interface is triggered to run in the foreground, the application is initialized, and the scheme of the initialized interface of the application is displayed: by adopting the scheme, when the camera application is restarted after being exited, the display of the preview interface can be restored, rather than the direct display of the initialized interface. First, after restoring the preview interface, the preview and editing of the film may continue. And secondly, displaying a preview interface after the video shooting is finished, wherein the shot video or the formed film is not stored at the moment, and the preview interface is restored to be displayed, so that the data loss can be avoided.

In some embodiments, after restoring the preview interface, further comprising: s417, the video editing application 313 saves the edited clip in response to the user' S operation of saving the clip (may also be referred to as a third operation). Illustratively, control 4 is included in the preview interface. Such as button 902 in interface 901 shown in fig. 9 (a). The control 4 is used for triggering the mobile phone to store video. The operation of saving the sheeting may be a click operation or a long press operation of the control 4 by the user.

It should be noted that if the video effect of the clip is not edited in the process of displaying the preview interface, the clip after editing is the clip with the video effect corresponding to the template 1; if the video effect of the clip is edited during the process of displaying the preview interface, the edited clip is a clip (which may also be referred to as a second clip) after adjusting one or more video effects based on the clip having the video effect corresponding to the template 1.

Further, during saving a slice, video editing application 313 may display a save prompt in the preview interface. The save prompt is used to prompt that a slice is being saved. For example, the saving hint is a hint 903 shown in (b) in fig. 9, and the hint 903 hint saving progress is 45%. The video editing application 313 may send a notification of the completion of saving to the camera application 312 in response to the end of saving, i.e., after the save progress reaches 100%. The camera 313 may display the interface 1, i.e., an interface including a plurality of template options, in response to the notification of the save completion. Such as interface 904 shown in fig. 9 (c). Thereby facilitating continued selection of the effect template to capture the video.

Because the mobile phone may include the software structures of the desktop application 311, the camera application 312, the video editing application 313, the window manager 321, and the like, the video processing method in the embodiment of the present application may be completed by using the mobile phone as an execution body. The video processing method provided in the embodiment of the present application will be described below with the implementation subject being a mobile phone. Specifically, as shown in fig. 10, the method includes:

S1001, the mobile phone responds to the end of video shooting, and a preview interface is displayed.

In the process of displaying the preview interface, the mobile phone responds to the preset operation of the user and can edit the film. For example, background music, genre, etc. switched to a piece.

S1002, in the process of displaying the preview interface, the mobile phone responds to the operation of returning to the main interface, displays the main interface of the mobile phone, controls the preview interface to enter a pause state, and stores data of the preview interface.

In the embodiment of the application, after the preview interface enters the pause state, the preview interface is not destroyed even if the preview interface is not displayed in the foreground.

S1003, the mobile phone responds to clicking operation of a camera icon in a main interface by a user to inquire whether the camera application is destroyed.

S1004, the mobile phone responds to the destruction of the camera application, and displays a view finding interface before photographing by the camera application.

S1005, the mobile phone responds to the fact that the camera application is not destroyed, controls the preview interface to enter a recovery state, and resumes displaying the preview interface according to the stored data of the preview interface.

In this embodiment of the present application, after the preview interface enters the restored state, displaying the preview interface in the foreground may be restored.

Similarly, in the process of displaying the preview interface, the mobile phone responds to the preset operation of the user and can edit the film. For example, background music, genre, etc. switched to a piece.

S1006, the mobile phone responds to the save operation of the user to save the film.

In summary, by adopting the method of the embodiment of the present application, after exiting from the preview, the mobile phone may resume displaying the preview interface after running the camera application in the foreground again, so as to facilitate the preview and editing to continue. In addition, in the process of displaying the preview interface, the video shot by the template is not stored yet, and the video can be stored into slices by restoring to display the preview interface, so that the shooting result is prevented from being lost.
