O.K – This is driving me crazy!
Just imported and successfully edited footage from my new JVC HD GZ-EX210 Camera into Final Cut Pro 7.
The finished, exported .mov file (using Export>Quicktime Movie) looks fine. However, whatever I do to try and successfully convert this.mov file into mpeg4 I either get sudden jerks (after a few seconds of the footage looking fine) or I get flickering and problems with jerkyness. Have tried using FCP, MPEG Streamclip and Compressor to no avail.
The original files before import via Log and Transfer were AVCHD 1920x1080p files (I believe the frame rate is 50 fps).
After FCP converted the files, movie inspector showed that the files are now:
Apple ProRes 422
Aspect Ratio Square
Frame Rate 29.97
Field Dominance: Upper (Odd)
After I dragged the files – now in my browser – into my sequence, FCP asked me if I wanted to set the sequence to the format of the clips I was editing, which I did.
Footage looks great in the sequence and no need to render it.
It may or may not be important to note regarding my problem that the camera is p (progresive scan). I don’t know if the FCP internal conversion of the camera files dealt with this. As I said – everything looks fine in the timeline.
The sequence settings show:
Frame size 1920×1080 - HDTV 1080i (16:9) > (NB: There is no setting in FCP for 1920×1080 50p – only 30p)
All other setings match what the movie inspector says.
