Hello there,
I hope somebody can help...
I am about to get a mac pro. I have 2 monitors and i would want to output my QT movie in DP to an LCD screen.
The problem is that there is no s-video out on the nu mac and both DVi ports are being used by the monitors.
So far i have that solution :
I just discovered u can now output video via firewire making any DV camecoder an available S-Video out port...
But I do get a lot of playback delay and find it hard to compensate it exactly.
What about EchoFire would that be an option ?
Any suggestions is more than welcome...
Big Thanks in advance-
Flo

Why? Is the delay not a constant offset?realflo wrote: But I do get a lot of playback delay and find it hard to compensate it exactly.
Do you have more than one device on your FW buss? If so, try putting your video on it's own separate buss from your drive and other FW devices. That may help.

DV does some weird things to sync, especially consumer cameras, and they all seem to behave a little differently. You might have better luck with a pro deck, you can find used Sony's around for pretty cheap. It's been a while since I had to deal with this issue, so I'm a bit foggy, but...
You should be able to adjust the video delay offset. Depending on the camera you're using, it's probably about 2 or 3 frames... just nudge the video track until it looks in sync. The offset SHOULD be constant. Just make a note of how much you're offsetting, because it will come up later when you conform sound and picture. (FCP has an internal setting for this, you tell it how many frames and it will compensate for the delay but I don't know whether DP has that facility).
It's been a few years since I used echofire, but as I recall it was very stable, although a little tricky to configure. I don't think it will solve your problem, as your delay is happening in the camera itself... but might be worth playing with a demo of echofire to find out.
Will DP let you output the audio to the camera? It would be worth trying as a test to see whether sound and picture are in sync coming out of the camera.
