25=25=25. simple. here it's 24=23.98=29.97.
Actually it's more like 24=25=25, which means us PAL watchers are used to watching almost every imported movie or filmed TV show at a higher pitch. Enterprise, for example - T'Pol sounds a lot lower on the downloads than she does on TV. But we do get a 1:1 ratio of film frames to video frames.
Recent showings of Stargate sound like they've tried to squeeze the audio rather than simply resampling it - it sounds the right pitch but has the occasional glitch. None of which helps you, CharlieX, but I think it's interesting
I could probably knock something up in C that could strip out repeated frames/fields (depending on how it was captured) but you'd have to feed it an image sequence (one Targa file per frame), and at 1mb per frame you'd need a lot of storage.
