DV tape
Hi all.
I have a question re FCP, and printing to a DV tape.If I create an entirely graphical composition in after effects or combustion that uses the native tools within that app (i.e no video footage to import),and maybe make text and a background rendered at uncompressed 10bit, then bring into FCP UC10bit sequence and print to a DV/DVCAM tape on a Sony DSR deck via SDI, is the quality on that tape Uncompressed???? Surely the quality of that style of transfer bypasses lossy DV codec…

DV tape can only record DV signals. A DV signal is compressed with the DV codec. There’s no way around that; it’s the ONLY thing the deck knows how to do.
You’d need a different tape format to record better quality.

So the deck itself compresses 5:1, even over SDI?

Absolutely it does over SDI. Even Digital Betacam compresses your video onto tape over SDI. There’s practically no way to escape compression going to tape.

BTW I believe that digibeta compression is 1.6:1. Not much, but it compresses it.

Thanks guys.
Appreciate the feedbackJustin

I thought it worked out to about 2.3 : 1, but lets not split hairs. It’s visually lossless over multiple generations, and that’s what counts.

Actually, I think that’s not strictly true.
I recall this little utility that allowed you to make data backups on DV tapes. That was over FW, of course, not SDI, but it makes me think the deck really don’t care about the data it’s writting on the tape.
I haven’t tried it, not even remember it’s name, so please forgive me if I’m incorrect.Xandru
