HD Format Problems Inside FCP

Hello,
I'm working on a show that was shot in multiple ways. All of the HD footage was shot using the Canon XLH1. Almost all of the HD footage was shot 1080p24, except for one segment which was shot 1080i60. Now, as we are trying to construct the final build, we can't get the 1080i60 footage to play well with the other footage. The footage looks fine in its own project file, but when copied and pasted into the final sequence, the motion is very jittery like there are a number of dropped frames. We've got a looming deadline and are hoping to get this looking perfect in the next few days. How can I get this footage to play well with the other footage?
An Ammendment to My Original Question by Jason McCaffrey on Dec 2, 2006 at 10:47:29 pm
I think this is an editing timebase problem. The problematic sequence is 29.97 and everything else is 23.98. I tried dropping the sequence in question into the final timeline whole (nested) and it said "Operation Not Allowed. You can't nest sequences with different editing timbases". I tried converting the footage to match in Compressor, but the converted footage looks horrible. Is there a good way around this (other than shooting consistently in the first place, because we're unfortunately very far past that stage)?

Try exporting the HDV clip as uncompressed HD in compressor. Don't change the frame rate. Then import that file back into Compressor and change the frame rate, and at the same time transfer it back to HDV. I'm thinking that the optical flow technology will work better that way using an all "i" frame format instead of the HDV format... big maybe here, but it's worth a try.

If you are editing 24p then I assume you are not
editing in an HDV set-up?
Depending on sequence settings....
You will need to:
1.) De-interlace the 60i footage.
2.) Use Cinema tools to conform the 29.97 de-interlaced file
to 23.98.
Dedicated plug-ins like Magic Bullitt will do this
conversion better but for the sake of time try the
2 steps above.
