The invention relates to a video processing method and device, a storage medium and an electronic equipment.The method comprises the steps that a target video is segmented into multiple video slices according to scenes, the target video comprises multiple scenes, and each video slice in the multiple video slices corresponds to one scene; a plurality of video features are obtained, the plurality of video features are in one-to-one correspondence with the plurality of video clips in the target slice, and the target slice belongs to the plurality of video slices; according to the plurality ofvideo features, a rate-distortion curve corresponding to the target video clip is determined from the plurality of video clips as a rate-distortion curve corresponding to a target slice, and the deviation degree between the first video feature and the second video feature is smaller than or equal to a first target threshold value; the first video feature is a video feature corresponding to the target video clip, and the second video feature is other video features except the first video feature in the plurality of video features.
Description
technical field [0001] The present application relates to the computer field, and in particular to a video processing method and device, a storage medium and an electronic device. Background technique [0002] The R-D (Rate-distortion, rate-distortion) curve is a very important "feature" in the video encoding process. Different videos have different R-D curves, and the R-D curve will also change after the encoder is changed. [0003] In related technologies, there are generally two estimation schemes for the R-D curve: [0004] 1) The first solution is to assume that there is a strong correlation between video frames and frames. During the encoding process, the R-D results of the previous frames are used to estimate the R-D curve of the future frame; [0005] 2) The second solution is to encode the same video or the most representative section of video selected from the video multiple times, and at the same time use different bit rate settings for each encoding. After encod...
