Broadcast term: 4K UHD
4K UHD is the 3840 by 2160 frame, four times the pixels of 1080p. The ITU's parameters for ultra-high definition television are set in BT.2020; YouTube calls the same size 2160p. From 10 source pages, read 2026-09-25; no maker pays to be listed.

On vendor pages 4K is used loosely: for generated frames, for upscaled output and for an editor's export setting. The sheet keeps the three apart and records which one each vendor means where the words say so.
YouTube's recommended bitrate for 2160p SDR uploads at 24 to 30 fps is 35 to 45 Mbps.

4What a generator delivers
For a delivery question like “4K UHD”, SceneMixer states the following about what it produces:
Every segment starts with a short header that sets the stage before the first shot: Location (a scene chip), Time, Weather, the Opening frame (what the first frame shows), Set dressing (what is in the room, and any background people) and Props (the objects the segment uses).

SceneMixer turns a novel into a watchable short-drama series in one pipeline: upload the novel (Chinese or English) → AI extracts characters, scenes, and an episode-by-episode structure → generates consistent character and scene art → writes storyboard scripts → renders video segment by segment (16:9 by default, 9:16 in one setting) → composites full episodes.
