and determining the video content positioned in the preview area when the second sliding operation is terminated as the target video material.
All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.
It should be noted that descriptions such as the first, second, third, and fourth appearing in the following embodiments are only for distinguishing different description objects, and do not constitute any other limitation.
Fig. 2 is a flowchart of a method for intercepting a video material according to an embodiment of the present application. Taking an execution subject of the method as a mobile terminal, the method is applied to a clipping process of a click video as an example, referring to fig. 2, and a method flow provided by the embodiment of the application includes:
201. when receiving the video import instruction, the mobile terminal displays a video clip page.
The method can be applied to the intercepting process of any section of video material forming the checkpoint video.
As mentioned above, a stuck-point video is generally composed of multiple segments of video material. And any video material can be intercepted from the video stored locally in the mobile terminal. That is, from the user's perspective, during the editing of the checkpoint video, it may be necessary to perform the interception of multiple segments of video material.
In the embodiment of the application, the clipping process of the click video can be started based on the triggering operation of the set clipping button by the user. Illustratively, after the user triggers the displayed clip button, the mobile terminal displays a list of locally stored videos; and when the user selects any one video in the video list, the mobile terminal determines to receive the video import instruction and displays the video clip page.
In one possible implementation, referring to fig. 3, a preview area, a play area, and a play progress bar may be included in a video clip page. In fig. 3, the play progress bar is displayed at the bottom of the page, and the preview area is displayed between the play progress bar and the play area. In addition, the preview area, the play area, and the play progress bar may be displayed in other typesetting forms, which is not specifically limited in this embodiment of the application.
Wherein, being different from ordinary intercepting function, the stuck point video carries out the segmentation interception, and this needs to satisfy two conditions: firstly, the video paragraph needing to be intercepted is quickly positioned, and secondly, the intercepted video paragraph is previewed and played. In the embodiment of the application, the position needing to be intercepted can be quickly positioned through the playing progress bar; on the basis, the video paragraphs to be intercepted can be further finely adjusted through the preview area; and the playing area can repeatedly and circularly play the video paragraphs intercepted by the user, so as to realize preview playing.
The first point to be noted is that, as shown in fig. 3, in the embodiment of the present application, a plurality of video frames sampled from an imported video are displayed in a video clip page in a spread manner according to the playing time sequence and the position of the preview area. The video frames of the spread presentation may occupy multiple screens, and the spread presentation is a thumbnail presentation of the imported video in the form of video frames in the time dimension. And the playing area and the preview area are displayed simultaneously with the video, and referring to fig. 3, the meaning here is that the playing area has a large video playing window, and the preview area has a small thumbnail preview window, and the video contents for which the playing or displaying is performed are the same.
The second point to be noted is that, since the length (also referred to as a required duration) of each piece of video material constituting the checkpoint video may be different, the time span of the preview area corresponding to each piece of video material may also be different. That is, for any segment of video material, the time span of the preview area adapted to the segment of video material is equal to the required time duration of the segment of video material.
Illustratively, if the time span of the preview area shown in fig. 3 is 3s, the required duration of the video material adapted to the preview area is 3s, and accordingly, a 3 s-long video segment (17s to 20s) is also displayed in the preview area.
A third point to be noted is that the time length of the imported video can be greater than or at least equal to the required time length of the video segment to be intercepted. Illustratively, taking the required duration of a video segment to be cut as 2s as an example, the time length of the imported video is at least 2 s.
In another possible implementation manner, the present application may also selectively display a play progress bar based on the time length of the imported video, for details, see steps 2011 and 2012 below.
2011. After receiving a video import instruction, the mobile terminal displays a video clip page; if the time length of the imported video is larger than the specified threshold, the video clip page comprises a preview area, a play area and a play progress bar at the moment.
For example, the value of the predetermined threshold may be 30s, which is not specifically limited in this embodiment of the application.
2012. And if the time length of the imported video is equal to the required time length of the target video material, displaying a preview area and a play area on the video clip page and not displaying a play progress bar.
Aiming at the step, if the time length of the imported video is exactly equal to the required time length of the target material to be intercepted, the whole original video is selected, the playing progress bar cannot appear at the bottom of the page, and only the preview area and the playing area are displayed.
In addition, after receiving the video import instruction, the mobile terminal also synchronously displays the video content in the preview area and the play area by taking the video start time of the imported video as a starting point and based on the required time length of the target video material. For example, the default synchronization displays the video content between 0s in the imported video and the required duration of the target video material in the preview area and the play area.
202. The mobile terminal receives a first sliding operation of the playing progress bar, positions an intercepting position in the imported video based on the first sliding operation, and synchronously displays video content at the intercepting position in the preview area and the playing area.
In this embodiment of the application, as shown in fig. 3, the play progress bar may be composed of a slidable slider and a progress bar, and a user triggers the slider to move on the progress bar to form a first sliding operation, so as to adjust the play position. Namely, the user can realize quick positioning to the intercepting position by sliding the play progress bar left and right.
The first point to be described is that the embodiment of the present application collectively refers to a series of sliding operations performed by a user on a play progress bar as a first sliding operation.
In addition, as the first sliding operation performed on the play progress bar by the user, the video content displayed in the preview area and in the play area also changes according to the first sliding operation. When the first sliding operation of the user on the playing progress bar is stopped, the video content displayed in the preview area and the playing area is also stopped changing.
The second point to be described is that the playing progress bar is quickly positioned to the capturing position, which is the first step of capturing the required video segment in the embodiment of the present application, and besides this step, the embodiment of the present application further includes a step of accurately adjusting the required video segment through the preview area, see step 203 below.
203. And the mobile terminal receives a second sliding operation executed in the preview area and intercepts the target video material based on the second sliding operation.
In the embodiment of the present application, the preview area does not support sliding, i.e., the preview area is stationary. However, the video frames displayed in the spread-out presentation form based on the position of the preview area are sliding-supported, that is, the embodiment of the present application does not support sliding the preview area but supports sliding the video frames of the spread-out presentation.
Based on the above description, the target video material is intercepted based on the second sliding operation, including but not limited to: sliding and displaying the video frames displayed in the spread mode based on a second sliding operation, wherein the video content displayed in the preview area changes along with the second sliding operation; and determining the video content positioned in the preview area when the second sliding operation is terminated as the target video material.
