am I breaking the rules or is this a bug?
Ok I have FCP 6.02 (latest) on a G5 Powerpc dual 2g and a Aja IO.
I have been using this system to do some extensive HDV editing and all is great.
So I had an urgent job that had to go out to HDCAM. I connected the firewire (separate card than what feeds the IO box) to a ‘HDV to HD-SDI box’ and then connected this box to my HDW1800 HDCAM deck. Then I connected the Aja IO RS422 deck control to the HDCAM deck. This is where I get adventurous…I have the project setup to play on ‘desktop’ in AV settings and unchecked ‘diff output for ETT’ in AV devices.
Then I drag the sequence to the source monitor and go ‘edit to tape’ and set an in edit point and click ‘insert’. Up comes an error box about desktop mode bla bla bla so I select cancel and leaving the edit to tape window up I go to AV settings then AV devices and select ‘diff output for ETT’ to HDV (checked).
Then I drag the required sequence from FCP’s browser over to the edit to tape window’s INSERT. It then shows ‘conforming HDV’ (first time only) and then says its ready and to click OK. So I do and the deck cues and edits, and the HDV material goes out to tape – excellent; BUT I can’t get the playback to go onto the tape at a consistent timecode. Each time I do it drops in late by various amounts arounnd +/- 12 frames.
I think “gee I have got it this far, surely it can go that little bit extra?”
I use this system with digibeta all the time and get accurate edit to tape so I am wondering if it is a HDV latency thing.
Anyone shed some light on this or is it that what I have described above should not have happened because I tricked the system?Baz
What would I do without the ‘UNDO’ button!!!!

HDV output via firewire is not really designed for anything but going to an HDV device. Even that is usually pretty dicey…it’s mostly treated as a one-way conduit in FCP…one way in.
I really doubt you’re going to get FCP to output in this fashion in any sort of consistent, repeatable manner.
I’d go find a Blackmagic or Kona card.

Not true you can go back to HDV tape, its a pain in the but but you can.
Happy Editing To You!!

It actually outputs fine to the HDCAM deck; its just the inaccurate drop in to the master that I am having trouble with.
FCP see’s the HDV to HD-SDI converter as a HDV device so there is no problem there. My only workaround was to edit out to HDCAM and then do a tape to tape edit to get it frame accurate. Double handling but it got the job done.
I have a blackmagic extreme but it is flat out and i was just trying to get the other work done on the SD/HDV system.Baz

And by pain in the but I only mean the conforming process.

Yes. I was aware. I used the word mostly.
Mastering back to HDV is given short thrift because it’s not really a professional delivery format.

Then it didn’t output in a consistent manner…which is what Nate was saying. What you are doing might work…and if you can deal with the manner in which you can achieve HDCAM with accurate TC, then go for it. But it is by no means the proper way of doing things. Best to get an HD card.
But, as I said, if you can live with this…then have at it.
