All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present invention, which is not described in detail herein.
Fig. 2 is a flowchart of a video cover generation method according to an embodiment of the present invention, where the method is applied to a terminal. Referring to fig. 2, the method includes:
step 201: and shooting a video, and displaying an editing page of the shot video when a shooting ending instruction is received, wherein a cover setting inlet is displayed on the editing page.
It should be noted that the shooting end instruction is used to instruct to end shooting, the shooting end instruction may be triggered by a user, and the user may trigger the shooting end instruction through operations such as a click operation, a slide operation, a voice operation, and a gesture operation, which is not limited in this embodiment of the present invention.
In addition, the edit page of the video is a page for setting the attribute of the video, which may include a cover page, a title, sound effects, lyrics, and the like of the video. In addition, in order to facilitate the user to watch the shot video in time, the video can be played on the editing page of the video, for example, the video can be played in the background of the editing page of the video.
Further, the cover setting entry is an entry for setting a cover of the video, and the cover setting entry may be used to jump to a cover setting page, which is a page for setting the cover of the video.
For example, fig. 3 shows an editing page of a captured video, on which various controls for setting the attributes of the video, such as controls for setting a cover page, a title input box, a sound effect setting button, a lyric switch option, and the like, are displayed, and the video is played in the background of the editing page.
Step 202: and when the preset operation on the cover setting entry is detected, determining that a cover setting instruction of the video is received.
It should be noted that the preset operation may be preset, for example, the preset operation may be preset click operation, slide operation, voice operation, gesture operation, and the like.
In addition, the video cover setting instruction is used for indicating to set the video cover, and after the video cover setting instruction is determined to be received, the user can jump to the cover setting page to set the video cover.
Step 203: when a cover setting instruction of the video is received, n key time points of the video are determined, a video frame of each key time point in the n key time points in the video is obtained as a key frame, and n is an integer greater than 1.
The operation of determining the n key time points of the video may be: randomly selecting n time points from the duration of the video, and taking each time point of the n time points as a key time point; or, equally dividing the duration of the video into n time segments, and taking the first time point of each time segment in the n time segments as a key time point.
It should be noted that, when a video frame at each key time point of the n key time points in the video is acquired as a key frame, for any key time point of the n key time points, if the video loses frames at the key time point, a video frame at a time point closest to the key time point in the video may be acquired as a key frame.
Step 204: and displaying the progress bar of the video, and displaying the acquired n key frames on the progress bar according to the n key time points.
It should be noted that, each position in the progress bar of the video is used to indicate each time point in the duration of the video, the progress bar has a sliding block thereon, and the sliding block on the progress bar can be dragged. The progress bar may be a line or a rectangular frame. When the progress bar is a line, the sliding block on the progress bar can be a point; when the progress bar is a rectangular frame, the slider on the progress bar may be a small rectangular frame.
It should be noted that, in the embodiment of the present invention, while the progress bar of the video is displayed, n key frames of the video may be displayed on the progress bar, and at this time, the user may quickly obtain the approximate content of the video through the n key frames, so that the user may conveniently and quickly and flexibly set the cover of the video in the following process.
The operation of displaying the acquired n key frames on the progress bar according to the n key time points may be: determining n positions on the progress bar for indicating the n key time points one by one; displaying the ith key frame in the n key frames in a display area corresponding to the ith position in the n positions, or displaying the ith key time point in the n key time points and the ith key frame in the n key frames in a display area corresponding to the ith position in the n positions, wherein i is an integer greater than 1 and less than or equal to n.
It should be noted that, the display area corresponding to the ith position in the n positions displays the ith key time point in the n key time points and the ith key frame in the n key frames, that is, the n key time points and the n key frames are displayed in a one-to-one correspondence manner.
In addition, the display area corresponding to the position in the progress bar may be preset, for example, when the progress bar is a line, the display area corresponding to the position in the progress bar may be located above or below the progress bar; when the progress bar is a rectangular frame, the display area corresponding to the position in the progress bar may be located in the progress bar.
It should be noted that, in the embodiment of the present invention, when the cover setting instruction of the video is received, not only the progress bar and the n key frames of the video may be displayed, but also at least one cover label may be displayed, and then, one cover label may be selected from the at least one cover label as the target label.
It should be noted that each cover label of the at least one cover label may be a dynamic image or a static image, and the target label is a cover label of a cover used to generate the video.
When a cover label is selected from the at least one cover label as a target label, a cover label may be randomly selected from the at least one cover label as the target label, or when a label selection instruction is received, the cover label selected from the at least one cover label as the target label by the label selection instruction may be selected.
It should be noted that the tag selection instruction is used to select the target tag from the at least one cover tag, the tag selection instruction may be triggered by a user, and the user may trigger the target tag through operations such as a click operation, a slide operation, a voice operation, and a gesture operation, which is not limited in this embodiment of the present invention.
After the progress bar and the n key frames of the video are displayed through the above step 204, the generation of the cover page of the video may be continued through the following step 205, or the generation of the cover page of the video may be continued through the following steps 206 to 208.
Step 205: when a cover page selection instruction is received, the key frame selected by the cover page selection instruction from the n key frames is determined as the cover page of the video.
It should be noted that the cover page selection instruction is used to select the cover page of the video from the n key frames, the cover page selection instruction may be triggered by a user, and the user may trigger the cover page selection instruction by operations such as a click operation, a slide operation, a voice operation, and a gesture operation, which is not limited in this embodiment of the present invention.
It is worth noting that in the embodiment of the present invention, n key frames of a video may be displayed, and at this time, a user may quickly obtain the approximate content of the video through the n key frames, and may quickly select a cover of the video from the n key frames, thereby not only improving the flexibility of setting a video cover, but also improving the representativeness of the set video cover, and further greatly improving the display effect of the video cover, so that the video may be better exposed to display, and a higher click amount may be obtained.
It is to be noted that, if the target tag is selected in the process of displaying the key frame selected by the cover selection instruction from the n key frames, the target tag may be displayed on the selected key frame, and the display parameter of the target tag on the selected key frame may be adjusted, and the display parameter may include at least one of size, position, and the like.
