Video transcoding method and device, storage medium and electronic equipment

The invention provides a video transcoding method and device, a storage medium and electronic equipment, which are applied to the technical field of image data processing, and the method comprises the steps: obtaining a first video clip, and determining a maximum code rate supported by the first video clip; performing CRF pre-transcoding on the first video clip to obtain a second video clip; determining a target video sub-clip in the second video clip; obtaining transcoding feature information based on a peak signal-to-noise ratio and a structural similarity index of a video frame; extracting code stream layer feature information; processing the transcoding feature information and the code stream layer feature information by using a prediction model to obtain a plurality of first average code rates; and selecting the transcoding parameter corresponding to the maximum to-be-selected average code rate to perform final transcoding on the first video, wherein the to-be-selected average code rate is the first aver
