Abstract: Disclosed is a video transcoding method which enhances the efficiency of segmentation transcoding, including: performing frame rate conversion analysis on a video to obtain result information of frame rate conversion and position information of an IDR frame, and dividing the video into first video clips according to the position information of the IDR frame; splicing all the first video clips to produce second video clips according to chronological order and preset rule; encoding all the second video clips to obtain statistical file of the video according to the result information of frame rate conversion; determining scene switching position of the video according to predetermined frame type of the statistical file; splicing all the first video clips to produce third video clips according to the scene switching position; encoding and splicing all the third video clips to produce a complete video file according to the result information of frame rate conversion.

Abstract: The embodiment of the present disclosure discloses a video transcoding method and a video transcoding device, used for solving the problems in the prior art that a user cannot clearly watch video content during watching and the user experience is reduced because the content of the sampled screen video is vague.
