Video conversion method and apparatus

A video conversion apparatus, comprising:

• at least one hardware processor;
• a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions instruct the at least one hardware processor to:
• receive a video source and to acquire compression distortion quality of the video source, wherein the compression distortion quality of the video source is based on one or more distortion parameters corresponding to a resolution of the video source, wherein the programming instructions instruct the at least one hardware processor to:
• obtain video code stream parameter values of the video source, wherein the video code stream parameter values comprise a bit rate of the video source, the resolution of the video source, and a frame rate of the video source;
• obtain, according to the resolution of the video source, the distortion parameters corresponding to the resolution of the video source, wherein the distortion parameters further comprise a highest quality of a video sequence of the video source, a bit rate point of a mean opinion score of the video sequence, a regulatory factor, and a complexity factor;
• and
• obtain the compression distortion quality of the video source according to the bit rate of the video source, the highest quality of the video sequence, the bit rate point of the mean opinion score of the video sequence, the regulatory factor, and the complexity factor;
• obtain, according to the compression distortion quality of the video source, a transcoding policy corresponding to the compression distortion quality of the video source, and to determine, according to the transcoding policy, whether the video source requires transcoding;
• generate transcoding parameters according to the transcoding policy if the video source requires transcoding, wherein the transcoding policy comprises target video quality, and the transcoding parameters comprise a target resolution, a target frame rate, and a target bit rate;
• and
• convert the video source according to the target resolution, the target frame rate, and the target bit rate, and to generate a transcoded video.
