Early on I saw 29.97fps in the project window and wondered what the heck! I made sure my comp was 23.976, (matching my fcp timeline), don't know what happened however or why the Project Panel said 29.97. I guess the RAW sequence was brought in at 29.97?
It's a moot point now. How do I save this? Trash the Proxy? And how do I make sure this doesn't happen again?
Select your proxy in the Project Panel. Go to interpret footage and set the frame rate to match your comp. All done.
