That is, when the central axis is outside the range of 1.2 seconds before and after a shifting point, it is considered that a shifting point can be added to the position of the central axis to ensure that the minimum time length of the video clip will not be less than 1.2 seconds.

In some embodiments, the time interval between the corresponding moment of the central axis in the video track control and the corresponding moment of the shifting point in the video track control is greater than or equal to a second time threshold In this case, the electronic device displays the shift point management control as an add shift point control.

In the embodiment of the present application, in order to realize the management function (add function) of shifting points, referring to FIG. 7 , a shifting point management control 53 may also be displayed in the pop-up window 50 , and the video track control 20 in the central axis 22 When the time interval between the corresponding moment of , and the corresponding moment of the shifting point in the video track control 20 is greater than or equal to the second time threshold, it is determined that the central axis 22 is at the position where the shifting point can be added, At this time, the text in the shift point management control 53 can be changed to “Add shift point”, and the electronic device can add a new shift point at the position of the central axis 22 in response to the user triggering the shift point management control 53 .

In the embodiment of the present application, only one shift point management control can be used, and the management function of adding/deleting shift points can be implemented in a fast interactive manner, thereby reducing the complexity of the shift adjustment interface and operation logic.

Since the shift point at the start position and the shift point at the end position are considered inoperable, that is, cannot be deleted and dragged, the shift point or end position between the central axis 22 and the start position is considered inoperable. In the case of overlapping shift points, the shift point management control 53 can be set to an inoperable state. In addition, when the central axis 22 selects the shift point at the start position and the shift point at the end position, the shift point management control 53 is grayed out to inform the user that the shift point management control 53 is in an inoperable state at this time, and the shift point at the start position and the shift point at the end position cannot be processed.

In some embodiments, adjusting the length of the video track control based on the target speed change value further comprises:

In response to the target speed change value being greater than 1, the length of the video track control is shortened by the shortening multiple of the target speed change value and displayed.

In response to the target speed change value being greater than 0 and less than 1, the length of the video track control is displayed after being stretched by taking the inverse of the target speed speed value as the stretch multiple.

In the embodiment of the present application, the variable speed adjustment interface may include: the global variable speed adjustment interface of FIG. 3 , after entering the global variable speed adjustment interface of FIG. 3 in response to the global variable speed trigger operation on the target video, a global variable speed operation can be performed, Speed change refers to selecting a target speed change value through the speed change wheel control to change the speed of the entire target video. As shown in Figure 3, a 2x speed change value can be selected to perform 2x fast playback on the target video.

In the embodiment of the present application, since the length of the video track control reflects the length of the target video playback duration, performing variable speed adjustment on the target video will change the playback duration of the target video. The playback duration of the target video is shortened by 1/2; the playback duration of the target video can be increased by 2 times by performing a 1/2x speed change and slow playback of the target video.

In order to let the user intuitively feel the impact of the variable speed operation on the playback duration of the target video, the embodiment of the present application may adjust the length of the video track control correspondingly according to the target variable speed value. For example, referring to FIG. 3 , when the target variable speed value is 2x In this case, the length of the video track control can be changed to 1/2 of the length of the video track control when the variable speed value is 1x (normal playback speed), so that the user can intuitively perceive the 2x speed through the change of the length of the video track control.

For example, in Figure 4, the target video clip (the video clip corresponding to the interval area overlapping the central axis) is subjected to 4x speed change Fast playback can shorten the playing time of the target video clip by 1/4, then the length of the area corresponding to the target video clip in the video track control 20 can be shortened to 1/4.

Further, referring to FIG. 7 , if the target video clip (the video clip corresponding to the interval area overlapping with the central axis) is further adjusted from 4× variable speed fast playback to 2× variable speed fast playback, then the corresponding area of the target video clip in the video track control 20 is adjusted. The length is adjusted to 2 times the length of the corresponding area of the target video clip in the video track control 20 during 4x variable speed fast playback. The user can intuitively feel the influence of the variable speed operation on the playback duration of the target video clip.

In the embodiment of the present application, in the process of performing the free speed change, when the target speed change value is greater than 0 and less than 1, it can be considered that performing the slow playback operation on the target video clip will increase the playback duration of the target video clip. The user can intuitively feel the impact of the slow playback operation on the playback duration of the target video clip.
