On a 16 GB M4 Mac mini, Jellyfin tone-mapped a 67.4 Mbps 4K HDR10 remux to 4K with subtitle burn-in at 61 fps (H.264, VideoToolbox) and 102 fps (HEVC). The same file to 1080p with burn-in was about 140 fps. A 41.5 Mbps 4K HDR Blu-ray to 4K HEVC was about 130 fps.

Jellyfin Transcode Benchmarks — RandomNamer (M4 Mac mini)Notes from the source
CPU-only H.264 on that clip was 58 fps, so the media engine was only a small step up for AVC. The author says the M4 was up to twice the N100's framerate at less than half the power, without giving a watt figure, and that 8 Mbps output looked poor (the media engine will emit 1440p at that preset). 1080p did not scale linearly with the 4K speedup.
