Dear Brian,
Sorry for the confusion. Yes, I’m down scaling the original footage from 1080i to 720i. FCP 7 lets you set up a sequence that includes interlaced video, either upper or lower, when setting up a 720 project. I’ve set it up with square pixels, 29.97 fps, Apple ProRes 422.
There is no 720i option in FCP X. So I’ve had to go back to FCP 7 to finish a sequence where the 720i footage is involved.
I know 720i is non-standard, but I don’t want to loose any picture information in a transcode from the interlaced original footage to a 720p transcode. I suppose I could try to “blend” the two fields in a transcode, but I haven’t had a lot of success with that in the past. My main tool has been Compressor for all of my scaling, transcoding, etc.
Does this clarify my problem?
Thanks,
Michael
