Ok, so ive imported my 24p footage into FCP, almost done editing, and i realized i must have imported in 60i or something since as it is said the third and fourth frame are the same.... but ive almost finished editing the movie and don't want to have to do it again...

I am a mediocre FCP editor and i realized i don't know what to do

You just need to remove pulldown.

There are numerous threads on here about how to do that.

You can do it after you've edited, though I'd recommend doing it first the next time.

The free way of removing pulldown is described here:
http://eugenia.gnomefiles.org/2007/07/13/canon-hv20-24p-pulldown/
Otherwise, there are 3 commercial utilities that will do it from $100 to $800.

You may be able to remove the pulldown at this point.

However when you edit at 60i - the 3:2 pulldown makes it is possible make a cut halfway through a 24p frame.
If you have done that, there's a chance that the cadence of interlacing will change across the cut.

As a general principle its probably better to convert all source footage to 24p first - and then edit it natively in 24p

I used the Compressor method with ProRes and it worked like a charm. Although, that was before editing...

But I feel your pain. I used the DVX's 24P advanced mode on a complicated project and about halfway through editing I saw that even though I used the pulldown removal preset in FCP, the footage still came out to 29.97 instead of 23.98. Oops! I still have yet to go back and remaster that. Very painful.

alright, i fixed it... well i ended up reimporting the footage from my cam, to edit it again...

at least i know how to this time

something I've done before is to reconnect your edited media to files that you have removed pulldown on. It will say they dont match, but tell it to try anyway. Another way is to do the full edit in 60i and then run the finished product through something like JES deinterlacer, it can get weird on cuts, but with some tweaking you can get a useable result without reimporting/transcoding/editing

The camera breaks the cadence with every clip, anyhow, so running a finished edit through JES is no harder. (You just have to make sure you have it set to watch for them.)

The camera breaks the cadence with every clip
Is this a fact?

Yes, it is definitely the case. You can verify this either by watching the frames or by letting JES try to process without detecting breaks, inc which case you get a mess.
