Abstract

The invention is suitable for the video file editing field, and provides a video editing method and a terminal. The method comprises the following steps: reading a video file, a pre-stored subtitle file and a pre-stored mapping table, wherein subtitle bars included by the subtitle file and video frames of the video file are synchronous, and the corresponding relation of the subtitle bars and the video frames is stored in the mapping table; receiving subtitle bar editing instructions, wherein the subtitle bar editing instructions comprise a subtitle bar removing instruction, a subtitle bar copying instruction and a subtitle bar reordering instruction; analyzing the subtitle bar editing instructions; and editing the read video file according to the analysis result and the mapping table. According to the method and terminal provided by the invention embodiment, the frames required for modifying can be quickly positioned, thereby greatly accelerating the video modification speed.

Description

technical field [0001] The invention belongs to the field of video file editing, and in particular relates to a video editing method and terminal. Background technique [0002] In order to make the video frame, audio frame, and subtitle bar correspond more accurately, it is usually necessary to edit the produced video file. [0003] In the prior art, when an editor edits a video file, he mainly determines how to edit it by watching the video file repeatedly. The editor can only understand how to edit the video file after watching the entire video file or certain video paragraphs. the video file. In this method, when editing a video file with a long length of time, since the editor cannot obtain all subtitle information in a short time and obtain information on whether a specific subtitle bar and a specific frame in the video correspond one-to-one, it cannot be modified by modifying the subtitle bar. Modifying the corresponding frames in the video file requires a lot of tim...
