Hello
Well the Mac finally turned up last week. I've got a week to test it before the college order a further 19.
It's a Mac Pro Intel Quad system running Final Cut Studio 2.
When editing using the in built Line out in to an amp and speakers I have noticed that the audio is out of sync with what is being shown on the external CRT monitor.
I have a Panasonic DV camera connected via firewire 400. The settings are set to show all frames. When I set the settings to single frames I get audio but no video on the external monitor. Then when I set it to all frames and direct the audio through the DV camera everything is fine.
So to summarise -
To get syncronised audio through you must set the audio out to the DV cam because it doesn't work through the in built line out. Is there any way of getting it to work?
Thanks

Yes, you should expect to take the video and audio through the same route out - i.e. both through the Firewire via DV camera, thence to both the video and audio monitors.
If your audio is taking a different route to the video, I'm not surprised there is a different (small) signal delay.
The audio line output is probably synchronised with the computer monitor canvas, though, I assume?
Latency!
Hi
"No matter what signal format you use for external monitoring, all digital video and audio interfaces (including FireWire) introduce inherent processing delays (known as latency) to signals sent out of the computer.
By changing the frame offset value in Final Cut Pro, you can compensate for the delay between your computer display and external video and audio outputs."

To reinforce what Mooblie has said, you should ALWAYS monitor audio and video from the same device. However by using Frame Offset to get the Canvas Video in sync with the FW output, then the internal audio may be tweaked to give less latency.
20 Macs in a row - that could be one hell of a rendering or encoding cluster for Compressor or Shake ;)
That was quick. So I'll try off setting the values like you state and see if that works.
I'll get back to you.
Thanks

Yes I have read about using a series of Macs as a render farm. I do believe that Final Cut can also be configured to use the processors of other Macs on the same network. I think you'd need to be going through an Editshare or Xsan of some sort though.
UNFORTUNATELY 20 Apples have completed spent the budget for this year so there will be no networking what so ever! Not even for internet updates. The Macs will be re-cloned bi-monthly with all the updates they require. Though I know I mustn't grubble!!!! We are very fortunate......or should I say our students are very fortunate.
