Detailed Description

In the description of the embodiments of the present application, "at least one" means one or more, "a plurality" means two or more, unless otherwise specified. In addition, in order to facilitate clear description of technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items having substantially the same functions and actions. Those skilled in the art will appreciate that the terms "first," "second," etc. do not necessarily denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance. In the description of the embodiments of the present application, unless otherwise stated, the positions and forms of the interface elements in the interface schematic diagram are schematic, and in actual implementation, the positions and forms may be flexibly adjusted according to actual requirements.

The embodiment of the application provides a video processing method which can be applied to a scene for previewing a shot video in electronic equipment. For example, the electronic device in the embodiment of the present application may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) \ Virtual Reality (VR) device, and the like, and the embodiment of the present application does not particularly limit the specific form of the electronic device. In the following embodiments, the electronic device is mainly taken as a mobile phone as an example to explain the scheme of the present application.

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

In other embodiments, the mobile phone may capture a video to be previewed in a multi-mirror video mode. Under the multi-lens video mode, the mobile phone can adopt two or more cameras to shoot videos simultaneously. For example, the interface 103 shown in fig. 1A (b) is a viewfinder interface before recording in the multi-lens recording mode. The interface 103 includes

images

104 and 105 captured by two cameras (e.g., a rear main camera and a front camera). In the following embodiments, the multi-mirror video recording mode is mainly taken as an example to illustrate the solution of the present application.

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

In one scenario, the handset may take a video to be previewed with the selected effect template (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 various effects of background music, filters, special effects (such as twinkling stars), transition, photo frames, stickers, tails and the like. Template 1 is selected before video shooting, and the mobile phone can shoot a video by adopting template 1. For convenience of description, the template 1 may be referred to as a first template, and a group 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-lens recording mode is performed, for example, control 1 is a "micro movie" button 107 in the interface 103 shown in (b) of fig. 1A. The control 1 is used for triggering the mobile phone to select the effect template. The mobile phone can receive the click operation or long-time press operation of the user on the control 1. In response to a user clicking or long-pressing on control 1, 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 an interface 111 shown in fig. 1B (a), which includes a plurality of template options (shown in the dashed box) in the interface 111, such as options of "nice summer", "nice time light", "good mood", "easy weekend", and the like. The plurality of template options correspond to the plurality of effect templates one to one. The template options can be used for triggering the effect template selected by the mobile phone. The mobile phone can receive the selection operation of the user on any template option (which can be marked as option 1 and also can be called as a first option). In response to the selection operation of the user on option 1, the mobile phone may select an effect template (which may be denoted as template 1) corresponding to 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 mobile phone is the template corresponding to the "hello summer" option shown in (a) of fig. 1B. Control 2 is included in an interface (which may be referred to as interface 1, and may also be referred to as a fourth interface) displaying a plurality of template options, for example, control 2 is a button 112 in an interface 111 shown in fig. 1B (a). And the control 2 is used for triggering the mobile phone to shoot the video.

In some embodiments, after selecting the template 1, the mobile phone may receive operations (which may also be referred to as a fourth operation) such as a click operation, a long-press operation, or a sliding operation of the user on the control 2, which will be mainly described below with the click operation. In response to the click operation of the user on the control 2, the mobile phone may display a shooting preparation interface (which may be referred to as interface 2 and may also be referred to as a first interface). In the process of displaying the interface 2, the user can complete preparation work before shooting, such as adjusting the shooting angle, turning on or off background music of the template 1, and the like. For example, the interface 2 is the interface 113 shown in (B) of fig. 1B, and the interface 113 does not include a shooting timer, nor controls for ending shooting, pausing shooting, and the like, i.e., indicates that shooting has not been started yet. Also, a control 3, such as a button 114 in the interface 113 shown in (B) in fig. 1B, is included in the interface 2.

Further, after the interface 2 is displayed, the mobile phone may receive operations (which may also be referred to as a first operation) such as a click operation, a long-press operation, or a sliding operation of the user on the control 3. The following will also be explained mainly in terms of click operations. In response to the click operation of the user on the control 3, the mobile phone can start video shooting by using the template 1 and display a view interface (which can be recorded as the interface 3 and can also be referred to as a second interface) in the shooting. For example, the interface 3 is the interface 115 shown in (c) in fig. 1B. The interface 115 includes interface elements such as a shooting duration 00, an end shooting button 116, and a pause shooting button 117, and indicates that video shooting has been started.

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

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

In some embodiments, an end recording control, such as an end capture button 116 shown in (c) of fig. 1B, is included in the interface 3, and is used to trigger the mobile phone to end video capture. The event 1 may be a click operation or a long-press operation of the user on the end recording control, and the like.

In other embodiments, the template 1 has a swatch that exhibits the sheeting effect that can be obtained after a photograph taken using the template 1. Such as filters, background music, etc. Further, in order to ensure that the formed piece after being photographed by using the template 1 can keep a high consistency with the sample piece, that is: the user is allowed to see from the swatch as the final piece. 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 the film finally formed by using the template 1 is the same as the duration of the sample film of the template 1 (which may also be referred to as a first duration). That is, the template 1 may indicate that a video of a certain duration (which may be recorded as a preset duration) is photographed at the longest.

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

In another specific implementation manner, the video effect corresponding to the template 1 includes a trailer (which may also be referred to as a first trailer), and the trailer is fixed content, such as an animation of a logo (logo) of a mobile phone manufacturer, and is unrelated to the content of the current shot. 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 duration and the end-of-slice duration (which may also be referred to as the second duration) is equal to the sample duration, that is, the preset duration is equal to the difference between the sample duration and the end-of-slice duration. Illustratively, if the template 1 is "your summer", "the duration of the sample of your summer" is 15s, and the video effect corresponding to the template 1 includes 1s of trailers, the predicted duration is (15-1) s =14s, as shown in (c) of fig. 1B, in the

interface

115, 00 is included, which is used to indicate that the preset duration is 14s.

It should be understood that the manner of indicating the preset time period by the sample of the template 1 is only an optional manner, and the actual implementation is not limited thereto. For example, the preset time length may also be indicated by the time length of the background music of the template 1 so that the formed piece cannot exceed the time length of the background music.

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

For example, taking the current shooting duration as the duration 00 on the left side of the "/" inside the dashed line frame in the interface 121 shown in (a) in fig. 1C.

After finishing the shot, the handset can form a film with the video effect indicated by template 1. That is, after selecting template 1, the mobile phone can capture a video using template 1, resulting in a film with the video effect indicated by template 1. Wherein, adopt template 1 to shoot the video and include: in the process of shooting the 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 viewing interface, for example, a filter, a sticker, background music and the like can be added in real time. And/or, the shooting of the video by adopting the template 1 comprises the following steps: after the video shooting is finished, the mobile phone performs post-processing on the shot video according to the template 1, and adds a video effect. In a specific implementation manner, effects such as background music, filters, stickers and photo frames can be added in real time in the shooting process, and effects such as transition and end of the line can be added only after the shooting is finished.

After forming a tile (also referred to as a first tile), the cell phone can display a preview interface of the tile (also referred to as a third interface). In the preview interface, the effects of the tiles 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 finished films in the interface 122 have the effects of a light gray filter, a sticker that makes people in summer sentiment and the most beautiful summer together, and the like.

In addition, in a preview interface, the mobile phone can edit the film. That is, the preview interface may also be understood as a fragmented editing interface. After the preview interface is displayed, the mobile phone can receive preset operation of a user, and the preset operation is used for triggering the effect of editing and adjusting the mobile phone into a piece. For example, editing effects such as background music, filters, special effects (e.g., flashing stars), transitions, photo frames, stickers, and trailers that adjust the tiles. The specific implementation of editing will be described in the following detailed embodiments, and will not be described in any way.

In the embodiment of the application, the mobile phone may display a preview interface in response to an event (such as event 1) that the video shooting is ended. In particular, after ending 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, by applying the video processing method provided by the embodiment of the application, in the process of displaying the preview interface, if the mobile phone exits from the front running camera application and returns to the main interface of the mobile phone, the preview interface exits at the moment. Thereby interrupting video editing. Subsequently, the mobile phone may receive a click operation of the user on a camera icon (which may also be referred to as a first icon) in the main interface, where the click operation is used to trigger the mobile phone to run a camera application in the front desk. Responding to the click operation of the user on the camera icon in the main interface, if the camera application still exists in the background of the mobile phone, namely: the camera application is not cleaned up, and the cell phone can resume displaying the preview interface again. So that the video can continue to be edited in the preview interface.

In summary, with the method of the embodiment of the present application, after exiting the preview interface, when the click operation of the user on the application icon of the camera application is detected again, the mobile phone may resume displaying the preview interface, so as to facilitate continuing to preview and edit the video. Therefore, the editing data can be prevented from being lost, and the human-computer interaction efficiency in the editing process is improved.

The electronic equipment can support 1 or N SIM card interfaces, and N is a positive integer greater than 1.

Referring to fig. 3, a block diagram of a part of a software structure of a mobile phone provided in the embodiment of the present application is shown. The software system of the mobile phone can adopt a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture or a cloud architecture. The embodiment of the application takes an Android (Android) system with a layered architecture as an example, and exemplifies a software structure of a mobile phone. The layered architecture can divide the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the android system is divided into four layers, which are an application layer (abbreviated as application layer), an application framework layer (abbreviated as framework layer), a Hardware Abstraction Layer (HAL) layer, and a Kernel layer (also called driver layer) from top to bottom.

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

Among them, 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 application programs in the mobile phone, such as application icons of application programs, such as a camera application, a gallery application, a calendar application, a call application, a map application, a music application, a video application, and a short message application. The desktop application 311 may also be used to receive various operations of the user on the main interface. Illustratively, the desktop application 311 may receive a user click, long press, or the like on an application icon. It should be understood that the main interface of the handset belongs to the desktop application 311.

The camera application 312 includes a plurality of shooting modules, such as a general shooting module, a portrait module, a general video module, a multi-mirror video module, and the like. Wherein, the multi-mirror video recording module further comprises a micro-video module. Illustratively, a "micro-movie" button 103 in the interface 103 shown in fig. 1A (b) may trigger the invocation of the micro-movie module. After the micro-shadow module is invoked, an effect template can be selected before shooting, and then the selected effect template is used to shoot the video. Further, the micro-cinema module may include a key-beat module and a segment-beat module (not shown). Wherein, a key claps the module and provides a key and claps the function, adopts a key to clap the function, and the cell-phone can be after selecting the effect template, once only shoots the piece that obtains having corresponding video effect. For example, the above examples of fig. 1B and 1C are functions of one-touch. The sectional shooting module provides a sectional shooting function, the sectional shooting function is adopted, and the mobile phone can finally form a film with a corresponding video effect by shooting multiple sections of videos after selecting an effect template. In the following embodiments, the present application will be mainly described by taking a one-touch function as an example.

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

The video editing application 313 may be understood as an editing application as described earlier. Video editing 313 a filmstrip preview module is included in the video editing application 313. In some embodiments, after the video is captured using the one-touch function, the cell phone may call a slice preview module in the video editing application 313 of the video editing application 313 to display a preview. Illustratively, the preview interface in the foregoing, such as the interface 122 shown in fig. 1C (b), is displayed by the camera application 312 after invoking the filmed preview module of the video editing application 313.

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

In this embodiment, the video editing application 313 further includes a page pause (onPause) interface and a page resume (onResume) interface. The page onPause interface can be called, so that the interface quit cannot be destroyed after being displayed in the foreground. So that the display of the interface can be resumed when the corresponding application is run again in the foreground. In some embodiments, as shown in fig. 3, when the main interface is returned from the preview interface, the page onPause interface may be called, so that the preview interface is not destroyed after exiting the preview interface displayed in the foreground. Thereby facilitating quick resumption of the preview interface upon re-entry into the camera application.

The page onResume interface can be called, so that the interface which is not destroyed in the background can be displayed in the foreground again, and therefore the user can interact with the interface again. In some embodiments, as shown in fig. 3, after the preview interface exits from being displayed in the foreground, when a click operation of the camera icon by the user is detected again, the page onResume interface may be called, so that after the camera application is entered again, the preview interface may be restored quickly.

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

The activity manager 321 can 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 sheet preview module may all interact with the activity manager 321 to enable management of the lifecycle of the preview interface.

The view system 322 can be used to build display interfaces for applications. Each display interface may be composed of one or more controls. Generally, a control may include an interface element such as an icon, button, menu, tab, text box, dialog box, status bar, navigation bar, widget, and the like. In some embodiments, as shown in FIG. 3, the view system 322 may render, display, such as render and display a preview interface, the interface according to the lifecycle of the page.

The video processing method of the embodiment of the application can be realized in a 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, the camera application 312 receives a user's click operation on a camera icon in the main interface, and then receives a launch request. Alternatively, the camera application 312 receives a user's click operation on a camera task in the multi-task interface, and may also receive a start request.

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

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

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

For event 1, refer to the description above, and the description is omitted here.

Illustratively, 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 and is equal to the preset duration, the event 1 is satisfied, and at this time, the video shooting may be ended.

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

In the embodiment of the present application, the camera application 312 calls the video editing application 313 to display a fragmented preview interface. For the preview interface, refer to the description in the foregoing, and the description is omitted here.

It should be noted that during use of the handset, the user is required to agree to the relevant user agreement of the video editing application 313 when the video editing application 313 is first invoked. Based on this, in some embodiments, the video editing application 313 responds to the invocation request, and if it is determined that the invocation is the first time, the video editing application 313 (e.g., a protocol confirmation module) displays the user's protocol and provides an option of agreeing or not for the user to select. The video editing application 313 may proceed to S405 in response to the user agreeing to the user agreement. Conversely, the video editing application 313 returns to display interface 1 in response to the user not agreeing 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 present embodiment, the video editing application 313 is invoked in the camera application 312 to display the preview interface. For example, the preview interface is the interface 122 shown in (b) in fig. 1C.

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

Illustratively, the preview interface includes an effect switching control, and the effect switching control is used for triggering the effect of switching the mobile phone into a piece. 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, the style switching control is used to trigger the mobile phone to switch to a piece style, and the style refers to an overall effect of the video effect of the template 1 except for background music, such as an overall effect of multiple effects, such as a filter, a sticker, a photo frame, and the like. As another example, the effect switching control may include a music switching control, such as music button 503 in interface 501 shown in fig. 5, for triggering the cell phone to switch to background music. As another example, the effect switching control may include an editing control, such as an editing button 504 in the interface 501 shown in fig. 5, for triggering the mobile phone to switch various effects such as background music, filter, sticker, photo frame, volume, and the like. The preset operation may be a click operation or a long-time press operation of the effect switching control by the user.

Further, the step of not detecting the preset operation of the user includes: starting from the first use of the mobile phone, in a scene of shooting a video by selecting an effect template, after shooting is finished and a preview interface is entered, a user input preset operation is never detected. For example, in the process of using a mobile phone historically, after selecting an effect template to shoot a video, the user clicks a style switching control in a preview interface, and when the preview interface is displayed at this time, the prompt information 3 is not displayed after the completion of playing a piece. In this way, repeated prompts by a user familiar with 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 by the user, the preset operation being for switching to a tiled effect. For the preset operation, reference may be made to the description in the foregoing embodiments, which are not repeated herein. For example, the preset operation may be a click operation of the user on the music button 602 in the interface 601 shown in (a) in fig. 6A. In response to the preset operation, the video editing application 313 may display a plurality of effect options in the preview interface, for example, the plurality of effect options are 4 music options of "relaxing", "summer", "animation", and "pleasure" in the pop-up window 603 shown in (b 1) in fig. 6A, and each music option corresponds to one background music.

The following mainly describes the specific implementation of the effect of switching to tiles by taking an example of switching background music.

In one specific implementation, a plurality of pieces of background music may be stored in the video editing application 313, and each piece of background music has a version with two durations, and the duration of the version 1 is the template duration of the effect template matched with the piece of background music. 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 and its matching effect template stored in the video editing application 313 are shown in table 1 below:

TABLE 1

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

Illustratively, taking table 1 above as an example, if the template 1 selected before shooting is "hello summer", the first music option may correspond to a release music of 15s version, and the second music option may correspond to a plurality of summer music of 30s version, a kinetic music of 30s version, a happy music of 30s version, a sad music of 30s version, a winter music of 30s version, and the like. For example, the video editing application 313 may display a popup 603 shown in (b 1) in fig. 6A, the popup 603 including 15s of a relaxing music option (i.e., a first music option) and 30s of summer music, 30s of kinetic music, 30s of cheering music (i.e., a second music option) therein. The template duration of "hello summer" is the music duration of the release music of version 1, i.e. 15s, and accordingly, the duration of the sequence formed in "hello summer" usually does not exceed 15s. Therefore, the length of music corresponding to the plurality of music options in the pop-up window 603 shown in (b 1) in fig. 6A can satisfy the entire piece.

In another specific implementation manner, the video editing application 313 also stores a plurality of pieces of background music, where each piece of background music includes version 1, which can be specifically seen from table 1. In the present implementation, the video editing application 313 may display a plurality of music options in response to a preset operation. The plurality of music selections includes a first music selection and a second music selection. The first music option corresponds to background music (denoted as music 1) matching the template 1, and the first music option corresponds to music 1 of version 1. The first music choice is usually only one. The second music option corresponds to the background music (denoted as music 3) matching the template 2, and the template duration of the template 2 is longer than or equal to the template duration of the template 1. In the following embodiments, the template duration of template 2 is mainly equal to the template duration of template 1. Since the music duration of the background music of version 1 is the same as the template duration of the effect template matched with the background music, the fact that the template duration of the template 2 is equal to the template duration of the template 1 can also be understood as: the music duration of the music 3 of version 1 is equal to the music duration of the music 1 of version 1. And the second music option corresponds to version 1 music 3. There may be one or more of the second music options. In this manner, the video editing application 313 can provide music that best matches the length of a filmed piece to the user, so that the operations such as deletion of music at the time of switching and fade-out processing of the ending can be reduced.

Illustratively, and also taking table 1 above as an example, if template 1 selected before shooting is "hello summer", then the first music option corresponds to a 15s version (i.e., version 1) of soothing music. The second music selection may correspond to one or more of a 15s version of summer music, a 15s version of kinetic music, and a 15s version of happy music. For example, the video editing application 313 may display a popup 604 shown in (b 2) in fig. 6A, the popup 604 including an option of a relaxing music of 15s version (i.e., a first music option) and summer music of 15s version, a kinetic music of 15s version, and a pleasant music of 15s version (i.e., a second music option).

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

In the foregoing description about the music selection, in order to distinguish between music and effect templates, the cover sheet and the name of the music selection are not associated with the corresponding effect template at all. In other embodiments, to reflect the association of music and effect templates, when displaying a plurality of music options, the cover page of the music option may be set as the template cover page of the corresponding music matching effect template, for example, the cover page of the first music option may be set as the cover page of template 1. Alternatively, the name of the music may be set to the template name of the corresponding music matching effect template, e.g., template 1 is "hello summer", and the name of the first music option may be set to "hello summer".

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

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

Subsequently, the mobile phone may receive an operation 1 of the user, where the operation 1 is used to trigger the mobile phone to switch the background music. Here, the operation 1 may be a slide-down operation from top to bottom of 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 includes a confirmation control, and operation 1 may be a click operation or a long-press operation of the user on the confirmation control. For example, the music popup is a popup 612 shown in (B) in fig. 6B, and a "√" button is included in the popup 612. The "√" button is a confirmation control. The operation 6 may be a click operation of the "√" button by the user. The embodiment of the present application does not specifically limit the form of operation 1. In response to operation 1, the cell phone may close the plurality of music selections and resume displaying the preview interface that does not include the music selections. For example, the interface 601 shown in (a) in fig. 6A may be displayed.

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

In displaying the preview interface, the user may input an operation to return to the main interface, causing the preview to be interrupted. In the embodiment of the present application, in response to the operation of returning to the main interface, not only the main interface may be displayed, which is described in detail in S406 below, but also the preview interface may be controlled to enter a pause state, which is described in S407-S408 below.

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

Wherein, the operation of returning to the desktop can be the user sliding upwards from the bottom of the preview interface. Or, the operation of returning to the desktop may be a user clicking a preset control (e.g., a home key) suspended in the screen. In the following embodiments, the user will mainly slide up from the bottom of the preview interface as an example. For convenience of explanation, the operation of returning to the home interface may be referred to as a second operation.

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

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

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

It should be noted that the video editing application 313 (e.g., a page onPause interface) merely provides an entry that can control the preview interface to enter a pause state. The video editing application 313 (e.g., a page onPause interface) needs to call the activity manager 321, so as to implement state management after the preview interface enters the background.

It should be noted that the foregoing S407 and S408 have no absolute sequential order. For example, S406 and S407 may be performed simultaneously. For another example, S407 may be executed first, and then S406 may be executed. The embodiment of the present application is not particularly limited to this.

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

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

And the data of the preview interface comprises the content displayed in the interface. In some embodiments, the data of the preview interface also includes edit data generated at the preview interface, such as switched background music, genre, etc. data. So that all user manipulations of the tiles 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 can click the camera icon to trigger the mobile phone to run the camera application again in the foreground. For example, a user clicking on the camera icon 802 in the interface 801 shown in fig. 8 (a) may trigger the cell phone 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 queries whether the background process is destroyed.

If the background process of the camera application 312 is not destroyed, it indicates that the camera application 312 is still present in the background. Accordingly, a call relationship (which may also be referred to as a call stack) in which the camera application 312 calls the video editing application 313 to display the preview interface still exists. In this embodiment of the present application, for this case, S412 is executed 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 call relationship in which the camera application 312 calls the video editing application 313 to display the preview interface does not exist. In this case, the call relationship cannot be acquired, and only initialization is performed when the camera application 312 is started, and an interface initialized by the camera application 312 is displayed, for example, a framing interface before photographing. Illustratively, in response to a user clicking the camera icon 802 in the interface 801 shown in (a) in fig. 8, if the camera application 312 is queried to be destroyed, the camera application 312 may display an interface 803 shown in (b 1) in fig. 8, where the interface 803 is a viewfinder interface before taking a picture and is an interface initialized by the camera application 312. Note that the text "camera application destroyed" in the interface 803 shown in (b 1) in fig. 8 is for illustration only, 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, the camera application 312 may query the call relationship of the camera application 312 calling the video editing application 313, and the camera application 312 may call the video editing application 313 (for example, a page onResume interface) according to the call relationship to request to display a preview interface.

S413, the video editing application 313 sends a call request to the window manager 321.

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

S414, the window manager 321 controls the preview interface to enter the resume state from the pause state, and resumes the data of the preview interface.

The recovery state (which 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 window manager 321 needs to invoke the capabilities of the view system 322 to render and display when restoring the preview interface.

S415, the window manager 321 sends 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 (a) in fig. 8, if it is queried that the camera application is not destroyed, the video editing application 313 may display an interface 804 shown in (b 2) in fig. 8, the interface 804 being a fragmented preview interface. Note that the word "camera application is not destroyed" in the interface 803 shown in (b 2) in fig. 8 is for illustration only, and is not usually displayed on the interface in practice.

After resuming to display the preview interface, the video editing application 313 may continue to switch to the tiled effect in response to the user's preset operation. For a specific implementation of the effect of switching to the tiles, reference may be made to the related description in S405, and details are not described here.

Therefore, through the foregoing S403 to S416, in a scene where the camera application 312 calls the video editing application 313 to display the preview interface after the video shooting is finished, if the camera application 312 exits from the background of the mobile phone and is triggered to run in the foreground again through the camera icon in the main interface, the video editing application 313 may resume displaying the preview interface.

Compared with the conventional technology, in the process of using system applications such as a camera, a gallery, settings, contacts and the like in the mobile phone, the method returns to the main interface of the mobile phone, and then initializes the application when the foreground runs by triggering the application icon on the main interface again, and displays the application initialization interface: by adopting the scheme, when the camera application is restarted after quitting, the preview interface can be restored to be displayed instead of the initialized interface which is directly displayed. First, after the preview interface is restored, the preview and editing of the tiles can continue. And secondly, displaying a preview interface after the video shooting is finished, wherein the shot video or the formed piece is not stored, and restoring to display the preview interface so as to avoid data loss.

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

Note that if the video effect of the slice is not edited in the process of displaying the preview interface, the edited slice is the slice with the video effect corresponding to the template 1; if the video effect is edited during the process of displaying the preview interface, the edited video effect is the video effect with one or more video effects adjusted based on the video effect corresponding to the template 1 (which may also be referred to as a second slice).

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