The video pipeline for the video shorts section is different from the reviews section. The reviews section is an older video pipeline not optimized for today's video streaming needs. Whereas video shorts was purpose built with a much improved encoding pipeline alongside the video player. Unfortunately that team hasn't moved to using the new pipeline and re-encoded their videos. The older pipeline is basically in maintenance mode. (Source: Worked on the video shorts team)
