Mystery Snafu Burning FCP Sequence to DVD
In burning a DVD for a client today, I discovered a heretofore undiscovered catastrophe: archive footage that was supplied by the client stuttered looked horrible when played on our commercial DVD player. It played fine on the computer.
Details: Sequence is DV-NTSC. Rendered at Apple ProRes 422; YUV material all rendered in high-precision YUV; Motion Filtering Quality BEST. Exported Quicktime Movie using Current Settings. Brought QT into Compressor using preset DVD: Best Quality 90 minutes. Brought video and audio into DVD Studio Pro standard settings. Built/Formatted. Everything looked good in Preview at every stage.
When I played the DVD on our commercial DVD player (older model), all the video looked fine except the archive video we got from the client. I am told this looks fine in a computer’s DVD drive.
So, where did I go wrong? Might it have been during the capture process (it came on a DV tape)? If so, why does it look OK on the computer? And why does everything look fine in Preview, but not in the final burned disk?
Thanks for any light you can shed.

“Anything is possible.”
In other words, I’m totally screwed and there’s nothing I can do.
Great.

If it plays back fine on computer monitors, which are not interlaced, and poorly on TVs or monitors, which are interlaced, that would indicate that the archival footage has some type of improper interlacing. You’ll need to trace it back to see what the source footage was and how it was captured. Anything is possible, including the fact that the original source was improperly captured.

“No, you will need to diagnose the problem, then it can most likely be fixed with either FCP’s filters or one of the commercially available fields filters, which are typically better and more capable.

Fallow David advice and try to find where is the mistake. This is a problem that you may find often and you need to learn how to deal with.

This problem is see is with this statement:
[Paul Spillenger] “Details: Sequence is DV-NTSC. Rendered at Apple ProRes 422”
This doesn’t make sense. Also, you are talking about two different pixel sizes 720×480 vs 720×486 which might screw up the field order on playback if not handled correctly.

If this is in fact a problem, then what would be the best quality compression it would be safe to use?
thanks.

ProRes is fine, you just have to make sure that your dv footage has a center value of 0,-1 to account for the frame size difference and field order.

I don’t see any problem in building a DV NTSC Sequence and changing the codec to Prores.
Proress should works in 720×480, 720×486 or any other size that respect the Macroblocks structure.

Just trying to keep it proper. When you capture ProRes, you don’t capture 720×480.

Would be great that you could capture from DV to Proress 720×480.
In PAL-land would be great to capture Proress Lower First.
Is just a matter of the capture cards makers.
The only problem when changing field-order is just to remember the correct one:-)
