I actually found a good answer on another cow thread. Using the 7D footage is time consuming, but it appears to work in a 60i timeline.
This is what I did:
1. Transfer original footage to computer. (You probably don’t need this step, but I like to keep my files separate.)
2. Use Compressor to transcode footage with Apple Pro Res 422.
3. Bring it into a 24p sequence, edit, or just export the entire timeline as a quicktime video using HDV 60i.
4. Import into Final Cut project again.
Don’t know if there is an easier way, but at least it seems to work!
