Editing to tape via HDCAM with a DVCPRO HD sequence?
Folks –
I’m most likely doing something VERY wrong here.
I have a show that is on HDCAM tape, being captured off a HDW-M2000 into a shiny new quad-core Mac Pro that is running Final Cut Pro 6.0.1 via SDI on a Kona LHe.
We’ve played around with different HD compression formats. Initially I would’ve preferred the ProRes HD codec provided by AJA, but the image drifts horribly out of sync on the client monitor (a consumer Toshiba plasma TV). We’ve had better luck with the DVCPRO HD format, which looks fine and plays back to the monitor with no issues.
We can Print to Video back to the deck just fine; however, we need to send the tapes off with the customary bars/black/slate pre-roll and then the program starting at 01:00:00;00. Using Edit to Tape, the program also goes out, but the control light on the deck goes to red instead of green. On playback from the tape, audio has been laid back, but the image has all these red and green and blue artifacts on it.
I didn’t hassle with it too much, figuring that I had the weekend to puzzle over it. Is this just a simple “Don’t lay back to a Sony deck using a Panasonic codec” issue?

Did you capture your HDCAM material to 720p or 1080? If you captured to 720 than you need to set up FCP and the Kona to do a cross convert back to 1080. This is why your deck is showing a red light. It’s also why you get no picture on tape. The deck is set to record 1080 and you’re sending it 720.
We master 720p shows out to 1080 all the time with our Kona3 and a HDW D2000.Michael Alberts

yeah, sorry, I should’ve been specific… it’s at 1080i60 at 29.97

Then you should have zero issues with picture going back to the deck. We’ve done this in the past, a DVCPro HD timeline to HDCAM is no big deal. It’s just an HD-SDI signal as far as the deck is concerned.
Do you have the same reference going to the FCP system as th deck?

What kind of scratch drives do you have?

Thank you, walter, I’ll check and see if it isn’t some sort of reference issue. Come to think of it, that might be what’s tripping it up. So you’re saying that you’ve laid back to tape this way using Edit to Tape?
Regarding the scratch disk, it’s set to an XSAN volume. There hasn’t been an issue with bandwidth so far.

Are you attempting to do this to a completely blank tape or have you blacked and coded the first ten seconds or so (as you should)? You can’t do an assemble or insert edit with a completely blank tape.
As the others have stated, there should be no issues using the DVCPRO HD codec edit to an HDCAM tape. It’s done all the time.

What is your capture setting? I’ve found that it has to match whatever tape format you’re trying to lay off to. In your case, it should be 8 bit or 10 bit UC, at 1080i 29.97.
