The AJA won't work...at the moment.

I didn't think MBox 1 was supported in PR8, that was my point. Guess I was wrong.

If the QTs in the VSLE behave the same way, than QTs inside PT session, all pros and cons (and differences from VVTR) should be the same. There was another topic here in DUC about VS LE (@ PT Tdm MacOS I believe). The system looks really nice and easy to setup, you do not need any midi interfaces, fast lock-up time, ability to loop, etc.
But, the problem comes, when you need to have really tight sync. This means, that BB generator and SYNC hardware is a must. Vvtr has a RESYNC feature, which allows the picture to follow incoming timecode, comapare it with QT's timecode and corrects it, if nescessary. If the QT with VS LE really behaves the same way, than in the "audio" PT's empty session, it is pretty easy to check it with Syncheck. Without BB and SYNC there is a start error. With VVTR there is no start error.
From my point of view, this is the most important difference.

regards,
Kuba

Right on ! I've asked this question many times but was never able to get a straight answer from Digi. VS LE sort of work ok on smaller set up where sync does not need to be super tight, but then again, who would want to bother setting up a dedicated machine for video to run small session, mind as well do it in you PT machine. So VVTR Resync feature is definitely a huge advantage, BB and Sync HD will set me back 4K, so for now, VVTR's still the best option, it also supports the AJA hardware, wich to me, is definitely a step up in quality and support compare to Decklink product.

If you've got a video card with VVTR, I think you'll need reference (BB or Tri-Level) into both PT (Sync) and that video card. Otherwise, I cannot see any way to avoid a start error through the card's video output.

I suppose there is a nice advantage to not needing a SyncIO (-HD) for VVTR, though.

Postman,

if there could be a start error, a Syncheck device should defenetly show and measure this issue. But I have right readings (0ms delay between audio and video) EVERY TIME I hit play (10/10).
If you press play in PT, you may notice, that on VVTR MMC green light brights for a moment, then RESYNC (also for a moment) and finally TC (25fps) in my case (PAL).

And I can say, that I do not know, how it works, but it works. And I did both long forms and short forms with this setup.

regards,
Kuba

You do know that a SYNC I/O or HD is NOT needed on the VSLE machine right?
It's only needed on the ProTools HD side.

Default Re: Video Satellite LE versus Virtual VTR?

I asked the question here in DUC about start error and got the answer from Bob Brown, that in order to have a tight sync and to not have a start error issue, there is a need to drive both audio and video from one clock source. So: you need to have a SYNC or SYNC HD hardware on PT side and you need a genlockable video card on VS LE side.
As for VVTR, I'm describing a setup, which works on their internal clocks, but somehow plays audio in a perfect sync to video and vice versa.

Kuba

That is truely amazing. I know you are very meticulous and I believe you. I just do not understand how it is possible unless the audio is somehow referenced to the video coming off of the video card. I also do not understand how my wife puts up with me. Sometimes life is better with mysteries.
