Re: 24p to PAL conversion with Twixtor

23.976 is 24P and is correct: it's 29.97002997...(30P) multiplied by 4/5
PA - Progressive Advance is a way to store 24P in a 60i camera.
Essentially it copies 2 fields twice on a frame with the assumption that whatever loads it later will strip that out.

For the aspect ratio: I am not sure why the PAR (pixel aspect ratio) is 1.5? I have seen HDV is like 1440 but never 1280...

Finally to go from 24 to 25P (PAL Progressive) people usually recommand to duplicate a frame every 24, it's not like going from 24 to 30 or 30 to 24... Most film to PAL conversion just timestretch by 25/24 even if it makes the sound 4% different. Simply drop the footage in project bin, select it and Composition|Add to Render Queue and in Render Settings Use Frame Rate 25 instead of 24.
