..specifically Jeremy Garchow's Compressor workflow:
"OK, ready? here you go:
Export a ref movie form FCP and open that up in Compressor.
Make s new QT setting and in the Encoder tab hit the video settings button.
Choose the codec of your dreams and the set the frame rate to 29.97, then click OK.
Back in the encoder tab, set the audio drop down menu to Pass Through.
GO the frame controls tab on turn on frame controls.
Resize, Deinterlace, and Rate Conversions should all be set to Fast, and then turn the Output Fields to Upper Field First. Duration should be 100%
Leave the filters tab alone unless you want to tweak something there.
In the Geometry tab set the frame size to 100% of source if your movie is full raster HD, if not choose the closest equivalent of full raster (1920 or 1280).
Hit Submit. Wait. Then you have a 29.97 Upper Field first movie with correct 3:2 pulldown. You can now dance the marimba.
You can also do this in After Effects as well if you have After Effects.
This takes quite a while whereas CinemaTools' REVERSE TELECINE seems so quick and high quality. I'm a bit worried that the workflow above is not only slow, but potentially more quality-invasive than necessary. ...so I was wondering if there's another way to preserve quality but quickly convert from 23.976p to 29.97i.
