In the embodiment of the application, the electronic device can respond to the variable-speed trigger operation of the user on the target video, so as to enter the variable-speed adjustment interface. Specifically, referring to fig. 2, which shows a video playing speed adjustment interface diagram provided in an embodiment of the present application, fig. 2 shows an interface entered after a target video is selected and edited, including: a video preview area 10, a video track control 20, a primary navigation area 30. The video preview area 10 can perform preview playing on the target video.
In fig. 2, the primary navigation area 30 contains the buttons for the common editing functions of the target video, such as: a "shift" button; an "special effects" button; a "watermark" button; a "canvas" button, etc. In the embodiment of the present application, when a user has a demand for adjusting the playing speed of a target video, the user may trigger a "shift" button in the primary navigation area 30 to enter a shift adjustment interface as shown in fig. 3, where the shift adjustment interface shown in fig. 3 may include the video preview area 10, the video track control 20, and the shift roller control 40 is configured to select a corresponding shift value in response to an adjustment operation of the user.
Further, fig. 3 also includes a global gearshift control 51 and a free gearshift control 52, and the user can trigger the corresponding controls to enter the corresponding gearshift mode.
In this step, after the user triggers the free-shift control 52, the electronic device may enter a free-shift adjustment interface as shown in fig. 4 in response to the free-shift trigger operation on the target video. The free speed change means that a user can select any video clip in a target video and select a target speed change value corresponding to the video clip, and different video clips can have different speed change values.
Specifically, in fig. 3 and 4, the video track control 20 includes multiple video frames 21 of the target video, that is, the video track control 20 may display the target video in a frame sequential stream according to the playing time sequence of the target video, and two video frames 21 connected in the video track control 20 may be two adjacent video frames in the target video or two video frames separated by a certain time length in the target video. The user can slide the video track control 20 left and right, so as to conveniently view and select the contents of different positions of the target video.
The variable speed roller control 40 includes a scale roller capable of being slid left and right, and the scale roller has a plurality of variable speed values arranged at intervals, for example, a variable speed value of 2x indicates that a video is played at 2 times, and a variable speed value of 1/2x indicates that a video is played at 1/2 times.

In addition, if the user divides the target video into a plurality of video segments in advance, the shifting points 21 corresponding to the start times of the video segments can be automatically established in the length direction of the video track control 20 by using the start times of the video segments.
And 103, responding to the selection operation of the video track control, and selecting a target video clip from the plurality of video clips.
In the embodiment of the application, a user can slide the video track control left and right, so that the contents of different positions of the target video can be conveniently viewed and selected. Therefore, the electronic device can select the target video clip from the target video in response to the user's selection operation of the video track control.
For example, referring to fig. 4, the user selects a video clip corresponding to the interval region between the second and third shift points from the left as the target video clip by sliding the video track control 20 left and right.
And 104, responding to the adjustment operation of the variable speed roller control, and performing variable speed adjustment on the target video clip.
Specifically, referring to fig. 4, after selecting a target video segment, a user may slide a scale roller in the variable speed roller control 40 to select a target variable speed value for controlling the playing speed of the target video segment, wherein a center line 41 of the scale roller is disposed at a center position in the width direction of an area where the variable speed roller control 40 is located, and in a process of sliding the scale roller by the user, a variable speed value corresponding to a scale overlapped with the center line 41 is the target variable speed value. As in fig. 4, 4x is selected as the target shift value. The target video segment may then be 4x fast played based on the 4x fast play variable value.
In the embodiment of the application, electronic equipment can provide a user free variable speed adjusting interface after responding to the free variable speed triggering operation of a target video, so that the user can conveniently and quickly adjust the scale roller in the variable speed roller control, the target variable speed value can be quickly and visually selected in one interface, the target variable speed value is selected by adjusting the scale roller, a new interaction mode is realized, the interaction mode is more convenient and visual compared with a fragment variable speed mode in the related technology, and the user experience is improved.

Optionally, the variable speed adjustment mode for the target video includes a global variable speed mode and a free variable speed mode.
Further, the embodiment of the present application provides two speed changing modes: the method comprises global speed change and free speed change, wherein the global speed change refers to the speed change performed by selecting a target speed change value as the whole target video. Therefore, the embodiment of the present application may present the global shifting control 51 and the free shifting control 52 in the pop-up window 50, and the user may trigger the corresponding control to enter the corresponding shifting mode.

In practical application, one video clip may have a minimum time length limitation, so as to avoid an invaluable video clip with too short time, and in the video track control, different positions correspond to different picture frame playing times, and since an interval region between two shift points constitutes one video clip, a time interval between a time corresponding to one shift point and a time corresponding to another shift point needs to be smaller than the minimum time length that the video clip may have, preferably, the minimum time length that the video clip may have is 1.2 seconds.
In the embodiment of the present application, a function of deleting a speed change point is provided, and referring to fig. 6, an existing intermediate speed change point selected by a central axis 22 may be determined as a speed change point to be deleted, and specifically, how to determine that the central axis 22 selects the existing intermediate speed change point, in the embodiment of the present application, based on a setting that a minimum time length that a video clip may have is 1.2 seconds, a time interval between a time instant of the central axis in a video track control and a time instant of the existing intermediate speed change point in the video track control is less than or equal to a first time threshold of 0.6 seconds, and it is determined that the existing intermediate speed change point is selected for the central axis 22.

I.e., the central axis is within 0.6 seconds before and after a shift point, the central axis is considered to select the shift point, and the shift point is displayed in an enlarged and highlighted manner.
Optionally, the speed change point management control is displayed as a speed change point deletion control when a time interval between a corresponding time of the central axis in the video track control and a corresponding time of the existing intermediate speed change point in the video track control is less than or equal to a first time threshold.
In this embodiment of the application, in order to implement a management function (deletion function) on a shift point, referring to fig. 6, a shift point management control 53 may be further shown in the pop-up window 50, and when a time interval between a corresponding time of the central axis 22 in the video track control 20 and a corresponding time of an existing intermediate shift point in the video track control 20 is less than or equal to a first time threshold, it is considered that the central axis 22 selects the existing intermediate shift point, and at this time, a file in the shift point management control 53 may become a "delete shift point", and the electronic device may delete the existing intermediate shift point in the video track control 20 in response to a triggering operation of the shift point management control 53 by a user.

It should be noted that, in a case that the distance interval between the central axis and the existing intermediate speed change point is less than or equal to a preset distance threshold, the central axis is considered to be very close to the existing intermediate speed change point, and preferably, the preset distance threshold may be 30 pixel distance, that is, when the central axis is within a range of 30 pixel distance before and after one speed change point, the speed change point is absorbed to be overlapped with the central axis, and the speed change point is displayed in an enlarged manner.
Optionally, referring to fig. 7, a speed change point management control 53 is further displayed in the free speed change adjustment interface, and a central axis 22 is disposed in the center of the displayed area of the video track control 20; step 202 may specifically include:

In the embodiment of the present application, an adding function of the shift point is provided, and referring to fig. 7, the embodiment of the present application may determine that the central axis 22 is at the position where the variable speed can be added based on the setting that the minimum time length that the video clip may have is 1.2 seconds, where a time interval between the corresponding time of the central axis in the video track control and the corresponding time of the existing intermediate shift point in the video track control is greater than or equal to the second time threshold of 1.2 seconds. That is, when the central axis is out of the range of 1.2 seconds before and after one shifting point, it is considered that the shifting point can be added at the position of the central axis to ensure that the minimum time length of the video clip is not less than 1.2 seconds.
Optionally, the speed change point management control is displayed as a speed change point addition control when a time interval between a corresponding time of the central axis in the video track control and a corresponding time of the existing speed change point in the video track control is greater than or equal to a second time threshold.
In this embodiment of the application, in order to implement a management function (delete function) on a shift point, referring to fig. 7, a shift point management control 53 may be further shown in the pop-up window 50, and when a time interval between a corresponding time of the central axis 22 in the video track control 20 and a corresponding time of the existing shift point in the video track control 20 is greater than or equal to a second time threshold, it is determined that the central axis 22 is at a position where a variable speed can be added, at this time, a file in the shift point management control 53 may become "add a shift point", and the electronic device may add a new shift point at the position where the central axis 22 is located in response to a triggering operation of the shift point management control 53 by a user.
According to the embodiment of the application, only one speed change point management control is used, the adding/deleting management function of the speed change point can be realized in a quick and convenient interactive mode, and the complexity of a speed change adjusting interface and operation logic is reduced.
It should be noted that, the user may also perform a dragging operation on other shift points except for the shift point at the start position and the shift point at the end position of the video track control, so as to change the position of the dragged shift point in the video track control, thereby achieving the purpose of changing the division of the video segments.
The center of the displayed area of the video track control is provided with a central axis; in the video track control, an interval area formed between adjacent speed change points is used for reflecting a video clip.
Specifically, referring to fig. 4, selecting a target video clip may be implemented by using the video track control 20, and a user may slide the video track control 20 left and right along the length direction, so as to change a relative position relationship between a displayed region of the video track control 20 and the central axis 22, when the central axis 22 overlaps with one interval region, the video clip corresponding to the interval region is used as the target video clip, and in fig. 4, when the central axis 22 overlaps with the interval region between the second and third speed change points from the left, the video clip corresponding to the interval region may be used as the target video clip.
And step 204, highlighting the interval area overlapped with the central axis according to a preset mode.
Referring to fig. 4, in order to improve the user's perception of the selected target video segment, the embodiment of the present application may highlight the interval region corresponding to the target video segment according to a preset manner, for example, in fig. 4, the interval region overlapping with the central axis corresponds to the target video segment, and the interval region may be displayed in an enlarged manner, so as to improve the user's perception.
And step 206, adjusting the playing speed of the target video clip according to the target variable speed value.
In the embodiment of the present application, referring to fig. 4, while the target video segment is selected, the user may slide the scale roller in the variable speed roller control 40, so as to select a target variable speed value for controlling the playing speed of the target video segment, for example, in fig. 4, a variable speed value 4x is selected for a video segment corresponding to an interval region between the second and third variable speed points from the left. After the shift value of 4x is selected, the video clip can be played back at a speed that is 4x times faster.
Optionally, the method may further include:
and step 207, in the case that the shift point at the starting position and the shift point at the ending position in the video track control are in the displayed area of the video track control, displaying the shift point at the starting position and the shift point at the ending position in a color different from other shift points, and enabling the shift point at the starting position and the shift point at the ending position not to be processed.
Referring to fig. 8, when the shift points at the start position and the shift points at the end position in the video track control 20 are in the displayed area of the video track control 20, they may be displayed in a color different from the other shift points, for example, black shift points may be shown in the figure, since the shift points at the start position and the shift points at the end position are considered to be inoperable, that is, they cannot be deleted or dragged, the shift point management control 53 may be set in an inoperable state when the central axis 22 overlaps with the shift points at the start position or the shift points at the end position, and the shift point management control 53 may be grayed out to inform the user that the shift point management control 53 is in an inoperable state at this time and cannot process the shift points at the start position and the shift points at the end position when the central axis 22 selects the shift points at the start position and the shift points at the end position.
Optionally, referring to fig. 8, a speed change point management control is further displayed in the free speed change adjustment interface, and a central axis is disposed in the center of the displayed area of the video track control; the method may further comprise:
and 208, under the condition that the interval time between the corresponding time of the central axis in the video track control and the corresponding time of the variable speed point at the initial position or the variable speed point at the tail position in the video track control is less than or equal to a second time threshold, the variable speed point management control is in an inoperable state.
Alternatively, the second time threshold may be 1.2 seconds.
In this embodiment, referring to fig. 8, based on the setting that the minimum time length that a video clip may have is 1.2 seconds, when the corresponding time of the central axis in the video track control is less than or equal to the second time threshold, and when the interval time between the shift point at the start position and the shift point at the end position in the video track control and the corresponding time in the video track control is less than or equal to the second time threshold, in order to avoid that the minimum time length of the video clip at the beginning and the end of the video is less than 1.2 seconds, the shift point management control may be set to the inoperable state, and may be grayed out and displayed.
Step 209, under the condition that the interval time between the corresponding time of the central axis in the video track control and the corresponding time of the existing intermediate speed change point in the video track control is greater than a first time threshold and less than a second time threshold, the speed change point management control is in an inoperable state; the existing intermediate shift points include: and the other existing shifting points except for the shifting point at the starting position and the shifting point at the tail position of the video track control.
Alternatively, the first time threshold may be 0.6 seconds, and the second time threshold may be 1.2 seconds.
In the embodiment of the present application, regarding an existing intermediate speed change point other than a speed change point at a start position and a speed change point at an end position of a video track control, when a central axis is within 0.6 seconds before and after the existing intermediate speed change point, it is considered that the existing intermediate speed change point is selected by a central axis, the existing intermediate speed change point may be further deleted by a speed change point management control, and when the central axis is within 1.2 seconds after and 0.6 seconds before and after the existing intermediate speed change point, in order to avoid that a minimum time length of a video clip obtained by dividing the existing intermediate speed change point is less than 1.2 seconds, the speed change point management control should be set to an inoperable state, and the speed change point management control should be grayed out and displayed, so as to avoid performing an adding operation of the speed change point at a position outside 0.6 seconds before and after the existing intermediate speed change point and within 1.2 seconds.
Optionally, the method may further include:
and 210, responding to global variable speed trigger operation of the target video, and entering a global variable speed adjustment interface, wherein the global variable speed adjustment interface comprises a video track control and a variable speed roller control.
And step 211, responding to the adjustment operation of the variable-speed roller control, and performing variable-speed adjustment on the target video.
In an embodiment of the present application, the variable speed adjustment interface may include: the global variable speed adjustment interface of fig. 3 may perform a global variable speed operation after entering the global variable speed adjustment interface of fig. 3 in response to a global variable speed trigger operation on a target video, where the global variable speed refers to selecting a target variable speed value as a whole target video through a variable speed roller control to perform variable speed. As in fig. 3, a 2 × variable value can be selected to perform a 2 × fast playback of the target video.
And 212, adjusting the length of the video track control according to the target variable speed value.
In the embodiment of the application, since the length of the video track control reflects the length of the playing time of the target video, and the playing time of the target video can be changed by performing variable speed adjustment on the target video, for example, the playing time of the target video can be shortened by 1/2 by performing 2x variable speed fast playing on the target video; the target video is slowly played at a speed of 1/2x, so that the playing time of the target video can be increased by 2 times.
In order to enable a user to intuitively feel the influence of the speed change operation on the target video playing time, the length of the video track control can be correspondingly adjusted according to the target speed change value, for example, referring to fig. 3, when the target speed change value is 2x, the length of the video track control can be changed to 1/2 of the length of the video track control when the speed change value is 1x (normal playing speed), so that the user can intuitively perceive that the time length for putting down the target video at 2 times of speed is shortened by 1/2 through the change of the length of the video track control; referring to fig. 9, if the target variable speed value is adjusted from 2x to 4x, 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 2x, so that the purpose of dynamically adjusting the length of the video track control through the value of the target variable speed value is achieved.
Specifically, step 212 may specifically include:
and a substep 2121 of, when the target variable speed value is greater than 1, shortening the length of the video track control by taking the target variable speed value as a shortening factor.
In the embodiment of the present application, in the process of performing global speed change, when the target speed change value is greater than 1, it may be considered that a fast play operation is performed on a target video, so that a play duration of the target video is shortened, and in order to enable a user to intuitively feel an influence of the fast play operation on the play duration of the target video, the length of a video track control may be shortened by taking the target speed change value as a reduction multiple, for example, a 2x speed change fast play is performed on the target video, so that the play duration of the target video is shortened by 1/2, and the length of the video track control may be shortened by 1/2.
And a substep 2122 of extending the length of the video track control by taking the inverse of the target variable speed value as an extension multiple when the target variable speed value is greater than 0 and less than 1.
In the embodiment of the present application, in the process of performing global speed change, when the target speed change value is greater than 0 and less than 1, it may be considered that a slow play operation is performed on a target video, so that the play duration of the target video is lengthened, and in order to enable a user to intuitively feel an influence of the slow play operation on the play duration of the target video, in the embodiment of the present application, the length of a video track control may be extended by taking the reciprocal of the target speed change value as an extension multiple, for example, the target video is slowly played at a 1/2x speed change, so that the play duration of the target video is increased by 2 times, and the length of the video track control may be extended by 2 times.
Optionally, after step 206, the method may further include:
and step 213, under the condition that the target variable speed value is greater than 1, shortening the length of the area corresponding to the target video clip in the video track control by taking the target variable speed value as a shortening multiple.
In this embodiment, in the process of performing free speed change, when the target speed change value is greater than 1, it may be considered that a fast play operation is performed on the target video clip, so that the play duration of the target video clip is shortened, and in this embodiment, the length of the region corresponding to the target video clip in the video track control may be shortened by using the target speed change value as a reduction multiple, for example, in fig. 4, a 4x speed change fast play is performed on the target video clip (the video clip corresponding to the interval region overlapped with the central axis), so that the play duration of the target video clip is shortened by 1/4, and then the length of the region corresponding to the target video clip in the video track control 20 may be shortened to 1/4.
Further, referring to fig. 7, if the target video segment (the video segment corresponding to the interval region overlapping the central axis) is further adjusted from the 4x variable speed quick playback to the 2x variable speed quick playback, the length of the region corresponding to the target video segment in the video track control 20 is adjusted to be 2 times the length of the region corresponding to the target video segment in the video track control 20 during the 4x variable speed quick playback. The user can intuitively feel the influence of the variable speed operation on the playing time of the target video clip.
And 214, under the condition that the target variable speed value is greater than 0 and less than 1, extending the length of the region corresponding to the target video clip in the video track control by taking the reciprocal of the target variable speed value as an extension multiple.
In this embodiment of the present application, in the process of performing free speed change, when the target speed change value is greater than 0 and less than 1, it may be considered that a slow play operation is performed on the target video clip, so that the playing time of the target video clip is increased, and in order to enable a user to intuitively feel an influence of the slow play operation on the playing time of the target video clip, in the embodiment of the present application, the length of the region corresponding to the target video clip in the video track control may be extended by taking the reciprocal of the target speed change value as an extension multiple.
Optionally, in an implementation manner, step 205 may specifically include:
substep 2051, in response to an adjustment operation on a scale roller in the change roller control, determining a change value in the scale roller that overlaps with a center line of a display area of the change roller control as the target change value; the shift values that overlap the centerline have a highlighted background of a preset size and color.
And a substep 2052 of displaying the target gear change value at a preset position of a displayed area of the video track control.
Referring to fig. 10, in an implementation manner, in a process of selecting a target speed change value, a speed change value overlapping with a center line 41 of a display area of a speed change roller control 40 in a scale roller may be determined as the target speed change value, in order to improve a striking degree of the selected target speed change value, in an embodiment of the present application, a highlight display background 42 with a preset size and a preset color may be set for the target speed change value, and in addition, the target speed change value may be displayed at a preset position of the displayed area of a video track control, for example, in fig. 10, the target speed change value may be fixed at a lower left corner of the displayed area of the video track control to display the target speed change value. This approach may enable the critical information: the display of the target variable speed value is clearer and more stable.
Optionally, in another implementation manner, a central axis is arranged in the center of the displayed area of the video track control; step 205 may specifically include:
sub-step 2053, in response to an adjustment operation on a scale roller in the change roller control, determines a change value in the scale roller that overlaps with a center line of a display area of the change roller control as the target change value.
Substep 2054, displaying the target gear change value on one side of the central axis.
Referring to fig. 11, in another implementation manner, in the process of selecting the target speed change value, the speed change value overlapping with the center line 41 of the display area of the speed change roller control 40 in the scale roller may be determined as the target speed change value, and in order to improve the striking degree of the selected target speed change value, the target speed change value may be displayed on a fixed side of the central axis 22 in the embodiment of the present application, for example, the target speed change value may be displayed on a right side of the central axis 22 in fig. 11. This approach may enable the critical information: the display of the target shift value is visually more focused, reducing distraction.
