I have a 30p footage that I would like to put on a 24p timeline and have it extend the original duration. When I try to do that in FCP 5, it tries to keep the original duration by skipping one frame every 5 or 6 frames. I just want to keep all the original frames and I don't care about audio going out of sync. Any ideas guys of how that could be done?

Thank you very much in advance.

cinema tools does that somehow...not quite sure, but there are threads on here that have instructions.

Cinema Tools is part of Studio, which you should have if you've got FCP5 :)

Bingo. That does the trick. Thank you Cole. The only problem that in my case I am working with AVI files and Cinema Tools only accepts MOV files. But once its MOV, the conforming process does not require re-encoding, which is good.

excellent! Glad that worked for you.
