Hello Jim,
I did some 3:2 pulldown from 23.98fps to 29.97 with After Effects. The result is quite ok. The audio is not out of sync. But all the on screen text are flickering a bit.
I’m planing on trying with compressor 3. But I haven’t find any explications with the steps. May be on the Apple support website.
I did a reverse telecine with compressor 3 and the result was perfect. So I’m pretty sure that you can get a really good result on a 3:2 pulldown with compressor.
