View Full Version : Sync'ing up my preview monitor

My external preview monitor image slowly drifts out of sync over time. Adjustments in preferences don't help, it always drifts over time eventually.

After doing some research, I am assuming this is due to my sound card, a Creative Audigy II ZS, and that I need a capture card or breakout box of some kind, like those made by Canopus/Grass Valley to lock the audio to an external reference.

My question is, those of you who use a hardware solution to deal with this, what is your preference for hardware, keeping in mind that I am on a fairly limited budget? Sync'ing up that preview monitor is essential to me, mostly to keep people from breathing down my neck while I work.

Hey Kevin I'm anxiously waiting for answers to your question, as I just purchased a Black magic Sp card, and I'm wondering if I should use the outs from that for audio monitoring, or should I get a separate card?

I've never noticed much drift myself, but one quark I noticed, that I'll share with you, sometimes when using JKL a lot, I notice some drift. Just hit stop, and you'll see the video "catch up" after the audio stops. Now you're back in sync for a critical edit.

Yeah unfortunately I need to sit and screen assembled shows that are quite long so I can't afford any drift to happen. Anyone have any recommendations?

For that Blackmagic card why wouldn't you use it to monitor audio? Analog outs and SPDIF both on that I see. I suppose you would still be using your computer's sound card or mobo to monitor the PC's audio separately, through a mixing board, but that's just a guess...

Yeah I actually had a brainstorm the other day. I purchased a 4x4 Sierra router on E-bay. My plan was to make # 1 the Blackmagic card, and # 2 out my monitoring (Video to my plasma and audio through a mini mixer to a set of M-audio speakers) Then of course 3 & 4 can be tied into my dub decks. The nice thing about that is I can re route audio to monitor what's coming off the decks. Only probblem is I have to make up 16 or so XLR's and tie them into the router, so it'll be a bit before I get it up and running
