Abstract

The invention discloses a video timing correction method which comprises the steps of extracting audio data in a video to be corrected, and identifying voice text corresponding to human voice in the audio data; acquiring a text mouth shape waveform corresponding to a speech text from a pre-established text mouth shape database; recording a voice time section for playing the voice of a person, andgenerating a voice mouth waveform according to the voice time section and the text mouth waveform; extracting video data from a video to be corrected, and obtaining a picture mouth shape waveform corresponding to a portrait face in the video data; comparing the similarity of speech waveform and picture waveform, and correcting the timing of speech and picture according to the result of comparison.The invention also discloses a terminal, a computer-readable storage medium. The invention realizes the automatic detection of the consistency of audio and video playing when playing video, and automatically completes the timing correction of audio and video playing when inconsistency is detected, so as to improve the correction efficiency of audio and video synchronous playing.

Description

technical field [0001] The invention belongs to the technical field of audio and video processing, and in particular relates to a video timing correction method, a correction terminal and a computer-readable storage medium. Background technique [0002] When playing a video file, due to inconsistent audio and video timestamps, or the current video player is not compatible with the audio data and video data in the video file, etc., the audio may play faster or slower than the video, resulting in the playback of the video The sound does not match the video picture. The existing solution is to adjust the audio playback time by correcting the time stamp of the audio and video frame, or by manually setting the delay or playing the audio in advance during playback, but when the time stamp of the audio and video frame is incorrect, it will It cannot be corrected; the efficiency of manually adjusting the audio playback time by the user is low, and it is difficult to correct. [00...
