Technical Field

The present disclosure relates to the field of network technologies, and in particular, to a video editing method and apparatus, an electronic device, and a storage medium.

Background

In the current network application, a user can make a game picture into a short video for sharing. Specifically, the corresponding game video materials need to be stored first, and then the game video materials are edited by a video editing tool to obtain the edited short video, and the short video is shared on the short video platform.

However, in the above solution, the user needs to install the video clip tool in the electronic device in advance and have the basic video clip capability. When the user's video editing capabilities are low, it is difficult to create a quality short video based on the original game video material clip. Therefore, for users without the basic video clipping capability, the short video uploaded to the short video platform is only a relatively original video (i.e., un-clipped video, no dubbing, no subtitles, etc.), and the short video is viewed poorly and of low quality, which may result in consumer users brushing on some low quality video.

For most users, the video editing tool needs to be downloaded and installed, and the user needs to have video editing capability, and for users without video editing capability, it is difficult to create a good quality short video based on the original game video. Therefore, a short video shared by many users on the short video platform is actually a relatively original video, i.e., a video without clips, dubbing and subtitles, and the quality of the video is low, which affects the creation enthusiasm of the users and causes the users to browse some low-quality videos.

In order to solve the above problem, an embodiment of the present disclosure provides a video clipping method, where an electronic device may determine a plurality of target frame images in a video to be clipped, and acquire at least one video segment corresponding to the plurality of target frame images from the video to be clipped according to the determined plurality of target frame images. Further, the video synthesis processing is carried out on the at least one video segment to obtain a synthesized video, and multimedia resources are added to the synthesized video to obtain a target video. By the implementation mode, when a video clipping request and a video to be clipped are received, the video to be clipped is automatically processed, and the highlight video segment is determined from the video to be clipped and the video is synthesized, so that the clipped target video corresponding to the video to be clipped is generated quickly and efficiently, the video clipping efficiency is improved, and the quality of the video obtained after clipping is improved.

As shown in fig. 2, a flow chart of a video clipping method is shown, according to an exemplary embodiment, for application to an electronic device. The video clipping method may include S201-S204.

S201, receiving a video clip request and a video to be clipped;

wherein the video clip request is used for requesting to clip the video to be clipped.

Optionally, the embodiments of the present disclosure may be applied to an electronic device, which may be a client or a server, and as to which device of the client or the server is specifically applied, the present disclosure is not specifically limited according to specific situations.

It should be noted that, in the case that the embodiment of the present disclosure is applied to a client, receiving a video clip request and a video to be clipped may be understood as: the client acquires the video to be clipped from the local according to the video clipping instruction (namely the video clipping request); in the case where the embodiments of the present disclosure are applied to a server, the server may receive a video clip request and a video to be clipped sent by a client.

That is, it can be understood that, in the case where the embodiments of the present disclosure are applied to a client, the video clip request described above may be a locally generated video clip instruction.

S202, determining a plurality of target frame images in the video to be clipped, and acquiring at least one video segment from the video to be clipped according to the plurality of target frame images.

The at least one video segment is a video segment corresponding to the plurality of target frame images, and one video segment comprises at least one target frame image.

It should be noted that the plurality of target frame images are frame images corresponding to highlight content in the video to be clipped, that is, the at least one video segment is a highlight video segment in the video to be clipped. For example, in the case where the video to be clipped is a saved game video, the plurality of target frame images are: frame images corresponding to opponent moments, frame images corresponding to game winning moments and the like are eliminated.

Optionally, after the video to be clipped is obtained, the electronic device may traverse each frame image in the video to be clipped, so as to screen out a plurality of target frame images that satisfy the condition, and correspondingly obtain at least one video segment corresponding to the plurality of target frame images.
