In some embodiments, the mobile terminal 100 is configured to perform a video editing method 200 according to the present invention. Wherein the one or more programs 154 of the mobile terminal 100 include instructions for performing the video editing method 200 according to the present invention.
Fig. 2 shows a flow diagram of a video editing method 200 according to one embodiment of the invention. Referring to fig. 2, the method 200 begins in step S210, and in step S210, an audio editing interface is displayed based on a trigger to an audio operation interface in the video editing interface.
When a user needs to add an audio file (e.g., music) to a video file, the video file to which the audio file is to be added is first selected. It should be noted that, in the embodiment of the present invention, a typical video file is a short video, but is not limited to this, and may be any other type of video. The short video is an internet content transmission mode, and generally refers to video transmission content which is transmitted on a new internet medium within 5 minutes. As shown in fig. 3, a list of video files is presented in a display interface of the mobile terminal, and a user can select one or more video files in the list of video files. And if one video file is selected, the video file is the video file to which the audio file is to be added.
If a plurality of (6 selected in the figure) video files are selected, the video files can be spliced into one video file, and the spliced video file is the video file to which the audio file is to be added. Alternatively, instead of splicing temporarily, the video files to which the audio files are added may be spliced into one video file after the addition of the audio files is completed.
In this embodiment, one or more pieces of music may be added to one video file, or one or more pieces of music may be added to multiple video files, depending on the selection and operation of the user. A typical application scenario is to add music of different moods to each of a plurality of pieces of video.
And after the operation of selecting the video file is completed, presenting a video editing interface in a display interface of the mobile terminal according to the trigger of the user (for example, clicking a 'next' button). With continued reference to fig. 3, the video editing interface includes a video preview area in which the imported video may be played and a video editing toolbar located below the video preview area. The video editing toolbar includes a plurality of video editing icons or buttons, such as "filter", "music", "animation", "subtitle", and "MV", etc. The music button is the audio operation interface of the embodiment of the invention, and a user enters the audio editing interface by clicking the music button, so that music is added to the video file in the audio editing interface.
As shown in fig. 4, the audio editing interface has a video preview area (e.g., an area above the display interface), and the video preview area includes two tab pages, each of which is a floating display layer, e.g., a first floating layer corresponding to a "song library" tab page and a second floating layer corresponding to a "music editing" tab page. In the process of adding audio and editing audio, the video preview area can play the video to which the audio is added, so that a user can know the audio adding effect. And at the same time, only one of the two floating layers is displayed, namely the second floating layer is hidden when the first floating layer is displayed, and the first floating layer is hidden when the second floating layer is displayed. And displaying the audio file list in the first floating layer, and performing audio editing in the second floating layer.
After displaying the audio editing interface, the method 200 proceeds to step S220. In step S220, based on the selection operation of the audio file in the audio file list in the first floating layer (song library tab), the first floating layer is collapsed, and the second floating layer (music editing tab) is displayed.
When music is not added to the video file, a first floating layer, namely a song library tab, is displayed on an audio editing page by default. After one or more pieces of music have been added to the video file, the second floating layer is displayed by default on the audio editing interface. The user may also choose to display the first or second floating layer by clicking on it (e.g., clicking on the title "gallery" or "music edit" of the tab page), or, as described below, by clicking on the "+" button in the second floating layer (i.e., continuing the interface to add audio files).
With continued reference to FIG. 4, a list of audio files is displayed in the first floating layer, one audio file at a time being selectable by the user for addition to a video file. It should be noted that only 4 audio files are shown in the figure: song 1, song 2, song 3, and song 4, by performing a touch operation such as a slide-up operation in the audio file list display area, can also show other songs in the audio file list. After the user selects an audio file, such as song 1, the selected audio file may be audited and evoke both the "use" and "edit" buttons. Clicking the 'use' button, the audio file is directly added to the video file to be effective, and the video editing interface is returned. And clicking an 'edit' button, retracting the first floating layer and displaying the second floating layer.
After displaying the second float layer, the method 200 proceeds to step S230. In step S230, based on the first operation on the selected audio file in the second floating layer, a track file corresponding to the audio file is generated.
As shown in fig. 5, the second floating layer (music editing tab) includes a time-axis component and one or more bar components. The time axis component can also be a bar, which can present the time length of the video file and display the video thumbnails of the corresponding time points in time sequence. The plurality of horizontal bar-shaped components are sequentially arranged from top to bottom and used for displaying the selected one or more audio files. Specifically, each bar-shaped component is associated with a selected one of the audio files and is capable of displaying an audio name of the associated audio file. The left image has a bar element indicating that an audio file is added to the video file; the right diagram has three horizontal bars indicating that three audio files have been added to the video file.
And, the audio file associated with each horizontal bar corresponds to a track file, and the track file can be added to the video file according to the parameters of the track file (details on how to generate the track file and how to add the track file to the video file will be described later). Thus, each soundtrack file will correspond to a section of video (or a video clip of a video file) whose position in the timeline component (the section between the start time point and the end time point of the video clip), also referred to as the position of the soundtrack file in the timeline. For example, in the right drawing, a first bar corresponds to a first section of the time shaft component, a second bar corresponds to a second section of the time shaft component, and a third bar corresponds to a third section of the time shaft component.
The added audio file corresponds by default to the entire section of the video (shown in the left). When a selected audio file needs to be edited, an audio editing panel (alternatively referred to as a track editing drawer) is presented in the second floating layer. The audio editing panel comprises track parts for displaying tracks, where a track (soundtrack), i.e. a strip of parallel "tracks" seen in the sequencer software, each track defines the properties of the strip, such as the timbre of the track, the library of timbres, the number of channels, the input/output ports, the volume, etc., and each track corresponds to a track file.
The track unit has a first masking layer (the area between two sliders of the track unit in the right drawing) that covers the audio clip that is the audio source used to generate the track file. Correspondingly, the time axis component further has a second mask layer (black area of the time axis component in the right drawing), the video clip covered by the second mask layer is the video clip corresponding to the track file, and the position of the first mask layer corresponds to the position of the second mask layer. In the embodiment of the present invention, the position correspondence means that two display objects are aligned in the longitudinal direction of the display interface (have the same width and cover the same abscissa range).
As shown in fig. 6, in the present embodiment, two operation modes for the audio file are provided, i.e., the first operation may be a pinch and separate operation of a plurality of fingers in the first mask layer covered area of the track part (mode 1), or a drag operation in the first mask layer uncovered area of the track part (mode 2).
In the method 1, generating the audio track file corresponding to the audio file includes:
contracting or amplifying an audio clip of the audio file under the first mask layer based on the pinching and separating operations of the plurality of fingers;
recording the starting position of the audio segment in the audio file, the position of the audio segment in the time axis component corresponding to the starting position (namely the time stamp of the starting moment of the audio data in the video file corresponding to the time point) and the length of the audio segment as the audio track parameters;
and generating an audio track file corresponding to the audio file according to the audio track parameter.
It can be seen that in mode 1, the track selection can be gesture-contracted to intercept the duration. Along with the contraction of the audio track selection by the gesture of the user, the video thumbnail and the song title preview area (the bar-shaped component) are correspondingly contracted, so that the user can intuitively feel the connection mapping relation between the music and the video.
In the mode 2, generating the audio track file corresponding to the audio file includes:
moving the audio track based on the drag operation;
taking the starting position of the audio clip positioned under the first mask layer in the audio file, the position of the audio clip in the time axis component corresponding to the starting position (namely the time stamp of the starting moment of the audio data in the video file corresponding to the time point) and the length of the audio clip as the track parameters;
and generating an audio track file corresponding to the audio file according to the audio track parameter.
The application scenario of mode 2 is that the video segment to which music needs to be added is fixed in position, the starting position of music is selected by sliding the song track left and right, and the music selection section needs to be presented.
After the audio editing is completed (e.g., the user clicks the check icon in the figure), the method 200 proceeds to step S240. In step S240, the generated track file is added to the video file, and a new video file is generated. It should be noted that, each time an audio file is edited, an audio track file corresponding to the audio file is added to a video file; after the plurality of audio files are edited, the corresponding plurality of audio track files may be added to the video file. The video file may be one video file selected by the user, or may be a video file obtained by splicing a plurality of video files selected by the user.
As shown in fig. 7, the second floating layer may also include an interface (e.g., the "+" icon in the figure) for continuing to add audio files, which is triggered when the user clicks on the icon, the second floating layer collapses, and the first floating layer is displayed. In this way, the user can continue to select the audio file in the audio file list in the first floating layer, so as to add an audio file to the video file. The first diagram in fig. 7 is an audio editing interface with an audio file added (currently displaying a music editing tab and showing a bar), and after clicking the "+" icon, the user enters the gallery tab (the second diagram); selecting to add the next piece of music in the music library tab page, and entering a music editing tab page (a third picture); in the third diagram, two bar-shaped parts are displayed, which indicates that two audios are currently added, and the track part corresponding to the second bar-shaped part is displayed, so that the user can edit the second section of audio; the second section of audio editing is completed, and the audio track part (the fourth picture) is folded; continue clicking on the "+" icon to add and edit more audio; the fifth figure shows five horizontal bar elements indicating that five pieces of audio have been added to the video file and five track files have been generated. In addition, as can be seen from the fifth figure, the same music can be used by overlapping for a plurality of times, and the video clips corresponding to different track files can also have overlapping parts.
According to another embodiment, the audio editing panel in the second floating layer also has an audio setting interface for setting fade-in and fade-out effects, such as a "fade-in" button and a "fade-out" button in the figure. When editing an audio file, if the 'fade-in' or 'fade-out' effect is selected, when generating the audio track file corresponding to the audio file, the fade-in and fade-out parameters of the audio segment are also added to the audio track parameters, so that the music is excessively smoother in the connection process.
