Hi, I am new to using catalyst with audio. Got a show coming up in four weeks time and using catalyst to playback audio and video triggered from MagicQ PC.

I was advised to play the audio back on a new layer and ether use sync id or trigger both the layers at the same time.

In testing today i found that:
Triggering the layers together made the video out of sync with the audio by the time the clip completed (only about 12frames, but noticeable).
-
Syncing the layers by id kept the video and audio in sync but the layers hud had some funny jumping going on. I dont think this upset the video performance.

Finally!
Playing the video with audio mode 70 again kept both video and audio in sync. I did however loose the FPS reading on the layer window.


Please could you advise me on the best option to playback video and audio using catalyst.

Video files are 820x1024 AIC 25FPS. Audio: Linear PCM 48Hz, 16-Bit.
Edited in FCP and exported using QT.

Catalyst server:
OSX 10.6.6 / 4.40_m329 / DV dongle
MacPro 4,1 2.26 8 Core / 6GB / ATI HD 4870 / OCZ-Vertex SSD (playback)

Thank you for helping!!
