Abstract
A video transcoding method comprises decoding a first bit stream encoded by a first video encoding format to obtain decoded video data and side information, converting the decoded video data and side information into a form suitable for a second video encoding format to obtain converted video data and converted side information, and encoding the converted video data using motion vectors contained in the side information to obtain a second bit stream of the second video encoding format.
