“To do this, import the file to Compressor, add an HD1080p preset, then under the Video tab at right, go to the bottom to Quality>Retiming Quality, and pick “Reverse Telecine”. Then export that file and it should produce a 23.98p result with the advanced pulldown removed, which you can then import to FCPX.
Joe,
I was able to this with HD1080p setting which is a compressed h.264 but in Apple ProRes, the Reverse Telecine setting was grayed out.
