24 fps question

[Uptight]

Noob question since I don't understand about the technical stuff: if all movies are shot at 24 fps and the majority of discs present these contents at 23.976 fps, a "well defined robust standard" according to some, then why some random UHDs/Blu-rays are at 24 fps?????????

If we try to put any audio track in sync with the old media, it will be out of sync with the 24 fps.

Are these 24 fps discs exclusive to Europe and not from NTSC territory?

24fps is the cinema standard, 23.976fps is the broadcast standard held over from colour NTSC TV (I think black and white was 30 seconds).

Sound is separate (it's captured at a much higher rate), unless you're editing from different media, but adjusting to 99.9% or 100.1% brings everything into sync. As long as the work flow remains the same, there shouldn't be issues.

If a movie has been mastered by a European outfit there's no need for them to use the old legacy 23.98fps rate. StudioCanal master their stuff to 24fps exactly, have done for years. And because they do the encoding for their US distribution partner (Lionsgate) then even the American release of whatever movie will be 24fps exactly. But 23.98 and 24 have been part of the BD spec since day 1.

How do TVs handle 23.98 FPS? Does it just speed it up to 24 and do normal 3:2 pulldown or does it do something special?
