Abstract: Embodiments of the present disclosure relate to a method and an apparatus for determining a video bitrate, a computer device, and a storage medium, belonging to the field of video transcoding technologies. The method includes: selecting target video frames from video frames of a to-be-transcoded video according to a predefined interval; determining a pre-estimated video bitrate of the to-be-transcoded video according to bitrate feature information of the target video frames; obtaining a first relative relationship between the pre-estimated video bitrate and an actual video bitrate of the to-be-transcoded video; and determining a target video bitrate of the to-be-transcoded video according to the first relative relationship and bitrate requirement information of a target service platform, the target service platform being a service platform to which the to-be-transcoded video is applied after transcoded.

Abstract: A video transcoding method is described. A computer device obtains at least one initial quantization parameter used to encode at least one initial coding unit for generating an initial compressed video, and determines, according to the at least one initial quantization parameter, a current reference quantization parameter corresponding to a current coding unit in a current video frame that is generated by decoding the initial compressed video. The computer device determines an estimated quantization parameter for encoding the current coding unit, determines a first difference between the current reference quantization parameter and the estimated quantization parameter, and sets a target quantization parameter to be equal to or greater than the estimated quantization parameter according to the first difference. The computer device encodes the current coding unit according to the target quantization parameter.
