New problem with 3:2 Pulldown added files (Kevin or Dave?)
I had the problem a couple of days ago with the mixed frame rates (60i in 24p) and decided to follow the advice of adding pulldown to the 24p footage and finishing in 60i.
A couple of years ago when we first began working on this project, my (incorrect) solution was just to drop all the 24p footage into a 60i timeline, because i was operating under the mistaken assumption that FCP would add the pulldown “on the fly” during export. Not sure where I got that notion. I could see when stepping through the timeline that every 4th or 5th frame was being repeated, but when we played back the sequence we both agreed that the repeated frames were visually imperceptible. It’s only now that I’m finishing the dvd, that I had begun to worry about the overall integrity of the project, and that a more professional solution to the issue was needed – hence my recent post.
So I did as recommended, bringing the original 24p files into AE, dropping them into the Render Queue, and rendering them out as Lower Field first with a WWSSW pulldown pattern. I chose that pulldown pattern based on a post I had read in the LA FCP user group on broadcast specs.
The resulting file looks like I expected it to in Quicktime Player, with visible interlacing. When I step through frame by frame, nothing is repeated. It’s the same in the FCP viewer. The problem is when I drop the file into a matching specs sequence, and when I re-import the file into AE (footage interpreted for lower field) and create a comp. Once again, every 4th or 5th frame is repeated, but visually imperceptible when played back.
So what did I gain through the process? Why the repeated frames again? Is this just how FCP and AE display pulldown added footage? Or did I do something wrong? Could I save myself the trouble of all of the conversion and just go with my original jerry-rigged solution? -

The original rate was 23.976, and was thus reflected in the Footage Panel. I bypassed creating a comp, hoping to avoid the CS4 gamma shift, which I did.
You’re right about the monitor, and I will test it with one.
