For another example, the video shooting method of the present embodiment further includes: and respectively setting a second trigger event for adjusting the sequence of the corresponding video clips in the video clip sequence aiming at each video clip. Therefore, after the user finishes the operation of adjusting the sequence according to the definition of the second trigger event, the sequence of the operated video segments in the video segment sequence can be adjusted, and the sequence of other video segments in the video segment sequence can be further adaptively adjusted.
In this example, the trigger event for video editing of the video clip may be preset. The trigger event may be a default of software in the terminal device 1200 or may be user-defined.
In one example, the first trigger event may be set to be a click operation on a specific button. For example, a cross-selection control is provided on an icon of a video clip to set the first triggering event to be a click of the cross-selection control. For another example, the first trigger event may be set to perform a double-click operation on an icon of the video clip.
In one example, the second trigger event may be set to be a drag operation on an icon of the video segment, or the like.
In one embodiment, the video capture method of the present invention further includes the following step S2600:
step S2600, detecting the total duration of the current video segment sequence; and stopping the video shooting under the condition that the total time length reaches the preset time length.
In one example, there is a limit to the total duration of the video clip sequence, for example, the total duration does not exceed 30 seconds.
In one example, the terminal apparatus 1200 starts video shooting in response to a shooting start instruction until a shooting stop instruction is acquired. In the shooting process, whether the total duration of the current video clip sequence reaches a preset duration is detected. And under the condition that the total duration of the current video clip sequence reaches the preset duration, automatically stopping shooting of the current video clip without acquiring a shooting stop instruction.
In one embodiment, the video photographing method of the present invention further includes the following step S2700:
step S2700, before generating the video, providing a display window, wherein each video clip in the current video clip sequence is displayed in the display window; the triggering event comprises an operation on a display icon of the video clip in the presentation window.
In one example, the presentation window is provided in a region of the photographic interface.
In one example, the display window may be in the form of a pop-up window, or may be a floating window stacked on the shooting interface, or may directly use a certain area of the shooting interface as the display window.
In one example, the presentation window presents preview images, duration, etc. information for each video segment in the current sequence of video segments.
In one example, the ordering of the video segments in the sequence of video segments is represented by the position of their display icons in the presentation window. The ordering of the video segments is adjusted by adjusting the position of the displayed icons.
In one example, the step S2700 of providing the presentation window further includes the steps S2710-S2720 of:
in step S2710, an expansion entry is provided in the shooting interface where the video clip sequence is shot.
Step S2720, responding to a display operation triggered by the unfolding entrance, and providing a display window.
In one example, the expansion entrance is provided in the form of an expansion button arranged on the shooting interface, the user triggers the display operation by clicking the expansion button, and the terminal device provides the display window in response to the display operation. Therefore, the user can conveniently unfold the display window as required.
The step of providing the deployment entry in S2710 includes the following steps S2711 to S2712:
in step S2711, after the shooting of each video clip is completed, an expansion entry is provided.
In step S2712, the expansion entry is hidden during shooting of each video clip.
In one example, the end device 1200 starts video shooting in response to a shooting start instruction until a shooting stop instruction is acquired. During shooting of the video clip, namely in the case that a shooting start instruction is acquired and a shooting stop instruction is not acquired, the unfolding entrance is hidden so as not to interfere with shooting of a user. After the video is shot, namely under the condition that the shooting stop instruction is obtained, an expansion entrance is provided, so that a user can edit the video clip conveniently.

In one example, the stow entry is provided by way of a stow button provided at the capture interface. The user can trigger the retraction operation by clicking the retraction button, and the terminal equipment hides the display window in response to the retraction operation. Therefore, the user can conveniently hide the display window under the condition that the video is not required to be edited, and the interference of the display window to the shooting of the user is avoided.
The video shooting method in this example further includes the following steps S2750-S2760:
step S2750, in response to the display operation triggered via the expansion entry, further hiding a shooting control for triggering a shooting instruction;
step S2760, in response to a stow operation triggered via the stow entry, also provides a shooting control.
In one example, in response to a show operation triggered via the expand portal, a show window is provided while a capture control for triggering a capture instruction is also hidden. In response to a stow operation triggered via the stow entry, a capture control is also provided while hiding the presentation window.
Generally, the user's shooting of the video and editing of the video are not performed simultaneously. The shooting control and the display window are selected and provided according to the using state of the user, so that the shooting interface is simple and easy to use.
In one embodiment, the video capture method of the present invention further includes the following steps S2800-S2900:
step S2800, providing a progress bar showing a shooting progress of the video at a shooting interface where the sequence of video clips is shot, wherein the progress bar has a separation indication between adjacent video clips;
in step S2900, the progress bar is updated synchronously in response to the operation of updating the video clip sequence.
In one example, the progress of shooting of the video is represented by a progress bar. The progress bar is provided with separation prompts between adjacent video clips, so that the progress bar is divided into sub-progress bars corresponding to the video clips one by one, and the duration of the corresponding video clip is represented by the length of each sub-progress bar.
When the video segment sequence is updated, for example, a new video segment is shot, or the video segment sequence is edited, the progress bar is also updated synchronously.
In one example, there is a limit to the total duration of a sequence of video segments. In this case, the maximum length of the progress bar represents the maximum allowable total duration of the video clip sequence.
By providing the progress bar on the shooting interface, a user can conveniently know the shooting progress.
< example >
The following describes a process implemented by the video shooting method according to an embodiment of the present invention with a specific example.
The video shooting method in this example is implemented by the terminal apparatus 1200 shown in fig. 1.
Fig. 3 to 8 are schematic views of first to sixth states of a photographing interface during video photographing according to an embodiment of the present invention. The video shooting process in this example will be described below in conjunction with the state of the shooting interface.
Fig. 3 is a schematic diagram of a first state of the shooting interface. At this time, the user captures a sequence of video clips for generating a video through the terminal apparatus 1200. The lower part of the shooting interface is provided with a shooting control which can be a shooting button. The user can input a photographing instruction through the photographing button member.
In this example, the user takes a video clip by long-pressing the take button. When the user presses a shooting button, the terminal apparatus 1200 acquires a shooting start instruction and starts video shooting in response to the instruction. When the user keeps the pressed state of the shooting button, the video shooting is continuously performed. When the user releases the shooting button, the terminal apparatus 1200 acquires a shooting stop instruction and stops shooting in response to the instruction. Thus, the user inputs a set of corresponding shooting start instruction and shooting stop instruction to the terminal apparatus 1200 by a long-press operation of the shooting button once, so that a video clip can be shot.
In other examples, the user may input a set of shooting instructions by clicking the shooting button a first time to trigger a shooting start instruction and clicking the shooting button a second time to trigger a shooting stop instruction.
In this example, the terminal apparatus 1200 provides a progress bar on the upper part of the shooting interface. The progress bar is used to indicate the progress of video capture. For example, in the shooting state shown in fig. 3, the user is shooting the first video segment, and the progress bar at this time may reflect the duration of the currently shot video segment.
In this example, there is a limit to the total duration of the video clip sequence. The maximum length of the progress bar represents the maximum total length of time that the sequence of video segments is allowed to be shot.
Fig. 4 is a schematic diagram of a second state of the shooting interface. At this time, the user has shot a plurality of video clips by long-pressing the shooting button a plurality of times. Specifically, the video clip sequence at this time includes 4 video clips.
As shown in fig. 4, the progress bar above the shooting interface at this time is divided into 4 sub-progress bars according to the divided indication. The 4 sub-progress bars correspond to 4 video clips photographed successively in order from left to right. The length of each sub-progress bar represents the duration of the corresponding video clip.
As shown in fig. 4, when the terminal device 1200 is in a non-shooting state, an expansion button is provided as an expansion entry at the upper right portion of the shooting interface, and a user can trigger a presentation operation by clicking the expansion button, and the terminal device 1200 provides a presentation window to the user in response to the presentation operation.
Note that the terminal apparatus 1200 in fig. 3 is in a shooting state, and the expansion button is hidden.
After the user triggers the display operation, the shooting interface changes to the third state as shown in fig. 5.
As shown in fig. 5, a presentation window is now provided in the upper portion of the shooting interface. Display icons corresponding to the 4 video segments are included in the presentation window. Each display icon displays a preview (not shown) and a time length of a corresponding video clip, for example, the time lengths of the video clips corresponding to the 4 display icons from left to right in fig. 5 are 16 seconds, 4 seconds, 8 seconds, and 10 seconds in this order.
Further, the position of each display icon represents the ordering of the corresponding video segments in the sequence of video segments, e.g., the order of the display icons from left to right represents the front to back order of the corresponding video segments in the sequence.
By operating the display icon, a trigger event for video editing can be triggered, and further the update of the video clip sequence is realized.
For example, the top right corner of each display icon in FIG. 5 is provided with a cross-selection control. The user may trigger a first trigger event by clicking on the cross-selection control. The terminal device 1200 deletes the video segment corresponding to the display icon from the video segment sequence in response to the first trigger event.
For another example, as shown in FIG. 6, the user triggers a second trigger event by dragging the fourth displayed icon and swapping it with the third displayed icon. The terminal device 1200 switches the order of the video segments corresponding to the two display icons in the video segment sequence in response to the second trigger event. For example, the operation of the user to exchange the order of the third video clip and the fourth video clip is represented by hand symbols in fig. 6.
It should be noted that, after the user clicks the expansion button, the terminal device 1200 hides the shooting button while providing the display window. For example, in fig. 5 and 6, the shooting button below the shooting interface has been hidden. Because the shooting and editing of the video are usually not performed simultaneously, the number of buttons displayed in the shooting interface can be reduced, and the shooting interface is simpler.
It should be noted that, after the display operation is triggered by the expansion button, the expansion button itself is also hidden.
As shown in fig. 5 to 7, a stowing button as a stowing inlet is further provided below the display window. As shown in fig. 7, the user may trigger the stowing operation by clicking the stowing button, and the terminal device 1200 hides the display window in response to the stowing operation, and displays the hidden shooting button. At this time, the shooting interface changes to the state shown in fig. 8.
Note that, after the stow operation is triggered by the stow button, the stow button itself is also hidden.
In fig. 8, since the user exchanges the order of the third video clip and the fourth video clip, correspondingly, the positions of the third sub progress bar and the fourth sub progress bar are also exchanged, i.e., the terminal device 1200 synchronously updates the progress bars in response to the user's operation of updating the sequence of the video clips. Similarly, if a user deletes a certain video segment, the sub-progress bar corresponding to the video segment is also deleted.
Based on the state shown in fig. 8, the user can continue to take the video clip within the time limit. In this example, the maximum total duration of the sequence of video segments allowed to be captured is, for example, 60 seconds. Assuming that the user takes the 5 th video clip on the basis of the existing video clip sequence, when the video clip continues to be taken for the 22 nd second, since the total duration of the video clip sequence reaches 60 seconds at this time, even if the user does not trigger the shooting stop instruction, the terminal apparatus 1200 automatically stops shooting because the total duration reaches the limit condition.
In this example, as shown in fig. 4 and 8, in the case where a video clip sequence has been shot, the terminal apparatus 1200 is provided with a video generation button on the right side of the shooting button. The video generation button may be a save button. The user triggers a video generation instruction by clicking the save button, and the terminal apparatus 1200 generates a video from the latest video clip sequence in response to the video generation instruction and saves the generated video locally. For example, the terminal device 1200 splices the video segments in the latest video segment sequence together in the front-back order as represented by the display icon, resulting in the final video.
In this example, after the terminal apparatus 1200 provides the video generation button, the video generation button is displayed or hidden along with the video shooting button.
After the terminal device 1200 generates a video according to the video clip sequence and stores the video locally, the shooting interface thereof can return to the initial state again, which is convenient for the user to shoot the next video.
