1. A method, comprising:
determining, for each frame of multiple frames of a video stream to transcode, a prediction bit cost based on information indicated within a pass log for the video stream and one or more other frames of the multiple frames, wherein the one or more other frames are based on whether the frame is inter-predicted or intra-predicted;
segmenting the video stream into chunks determined based on the prediction bit costs associated with pairs of frames of the multiple frames that meet one or more chunk size thresholds; and
transcoding the chunks to produce a transcoded video stream.
