The DV codec is not lossless. So theoretical yes.
But if it will be noticeable I don't think so.
(there is a good reason for this).
I'm curious what that might be, as you can create the QuickTime DV file right from PP.
I need to insert chapter markers into the timeline in Final Cut so DVD Studio Pro on the Mac can recognize them.
I then render on the Mac because DVD Studio Pro can handle my fonts better than Encore.
If you have CS3 Production Premium or Master Collection it comes with Adobe Encore for DVD burning. You can also create the chapter markers in Compressor before bringing them into DVD SP, or create them directly in DVD SP (provided they are on a GOP boundary).
Alternatively, my company makes an app called QT Edit that will quickly add chapters to a QuickTime file without needing transcode it and it can import marker lists from other apps too.
DVD Studio Pro can handle my fonts better than Encore.
Hmm. I'm curious about that, too. What fonts is Encore having trouble with?
