What I was stating was that typically in order to get a 24fps movie to reach 25fps speed, they run the film faster which causes the audio to change pitch.
It makes people sound like they are sucking helium.
Using 25->29.97 pulldown preserves that speed change. It's really only a useful method when the original source was PAL video and not film.
The correct way is to re-encode at 23.976/720x480 and then run the audio through a re-encoder (BeSweet has a simple template for this) set to 25->23.976. This corrects the pitch change.
Of course I could be talking out of my butt. Can anyone confirm that the PAL T3 has audio speedup?
