That is, the deletion and adjustment of text and the deletion and adjustment of video and audio need to be completed in three steps. As a result, when major programs are broadcast, video drafts and text drafts must correspond one-to-one due to the needs of review and release through different channels. The work will consume a lot of working time, and the work process is cumbersome and boring

Embodiment Construction
[0090]The present invention will be further described below in conjunction with examples.
[0091] A video clipping method and clipping system provided by the present invention are mainly applied to video clipping. General video file formats are mp4, mts. According to statistics, the use of mp4 format accounts for 60% of all interviews, the use of mts format is about 35%, and the remaining 5% are other video formats. For example, when a reporter goes out to sample, a video file will be formed in the camera, and the suffix may be .mp4, .mts, etc. The reporter will copy the video file to the editing computer, import the video file into the editing system, and perform background video audio analysis and voice Chinese translation and creation of synchronous time stamps, and then the establishment of synchronous editing windows for text, video and audio.
[0092] Such as figure 2 As shown, the present invention provides a kind of video editing method, comprises the steps:

The invention discloses a video editing method and a editing system. The video editing method comprises the following steps: sep 1, decoding a video file and performing audio and video separation to obtain picture frame data, audio frame data and a synchronization table of the picture frame and the audio frame; step 2, translating the audio data into text synchronously; step 3, obtaining the starting time, ending time, and bottom noise or mute areas of each syllable in the audio, and constructing a synchronous timestamp of the text and the syllables in the audio; step 4, editing the text or audio in the editing window, and editing the picture frame data and the audio frame data synchronously or editing the picture frame data and the text synchronously according to the synchronization tableof the picture frame and the audio frame and the synchronous timestamp; and step 5, encapsulating and exporting the picture frame data, audio frame data and text after editing. Through the video editing method, the video editing efficiency can be greatly improved.
Description
technical field [0001] The invention belongs to the technical field of video voice, audio editing, and Chinese text editing, and in particular relates to a video editing method and an editing system. Background technique [0002] The editing of voice audio content of traditional radio stations and TV stations is mainly realized by using general-purpose video editing software (such as Adobe Premiere Pro software, Final Cut Pro software), and such software itself does not have a synchronous text editing window, such as figure 1 As shown, it is necessary to rely entirely on the auditory control of the human ear for manual cutting and modification, and the efficiency and accuracy are not high. Among them, it is generally to monitor the accompanying sound in the video manuscript, manually understand the corresponding text manuscript, and then use the wps software and audition software to work continuously, edit the audio and video while modifying the text file, and modify the aud...
