When we edit to tape, the video lags audio.

Bernardo,

Did you do an audio mixdown before the ETT? If not, give that a try. Even if you’ve done nothing to the audio or video, it can solve some weird problems…hope it helps.

When you edit, are your speakers connected to the outputs on the Kona? IOW, how do you know that the edit was actually in sync?

Make sure you don’t have the system sound output set to the Kona card, that’s always caused us sync issues.

Well the clients are not on site to try some of these suggestions out. One thing they did tell me is that everything works fine with a previous system they have MacPro with a previous version of Final Cut (they did not take note of the version). So I am guessing it has something to do with FCP 6.0.2 or 10.4.11 which is required for FCP 6.0.2

thanks for the replies. Will keep everyone posted after we do some test next week.

Im having the exact same issue

In overall when playing a sequence in the timeline, using an external monitor, the first second is in sync, then the video starts to slow down a few frames and the audio gets heavily out of sync.

This is only happening in the external monitor. The video in the canvas or viewer is in sync.

I have already installed more than 20 Konas LHe and this is a first.

I already tried the following:

– Updating to Leopard
– Formating my Mac Pro
– Installing/Uninstalling Kona Drivers
– Running software update
– Using a different, cable, breakout box, monitor, DVCPRO Deck,

Thanks in advance for your support.
