Abstract

The embodiment of the invention discloses a video processing method and device. One specific embodiment of the method comprises steps: a to-be-processed video is acquired, and the video is divided toat least one video clip according to a scene; as for the video clip in the at least one video clip, the features of the video clip are extracted; the features and a target video quality are inputted to a pre-trained coding parameter prediction model to obtain the coding parameter of the video clip, wherein the coding parameter prediction model is used for characterizing the corresponding relationship between the features of the video clip and the coding parameter under the target video quality; and according to the coding parameter corresponding to the video clip in the at least one video clip, the video is subjected to coding processing, and a video after coding is generated. The implementation mode realizes adaptive coding based on the scene content, the compression rate can be improved,and the video quality is enhanced.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technologies, and in particular to a method and device for processing video. Background technique [0002] Video transcoding (Video transcoding) refers to converting a compressed and encoded video stream into another video stream to adapt to different network bandwidths, different terminal processing capabilities, or different user requirements. [0003] Relevant content-adaptive coding technologies basically use multiple coding methods, that is, first use CRF (constant ratefactor, to ensure a certain quality and intelligently allocate code rate) coding to calculate the complexity factor of the entire video, and then adjust the entire video. The encoding parameters of the video, that is to say, the content adaptation is basically at the title level. [0004] However, for video content of different lengths, the scenes inside may be changeable, and different scenes mean a finer-g...
