audio problem out of FCP via kona
on Oct 19, 2007 at 3:43:43 am

Hi guys,
I have posted this on the FCP forum too but we've got a curly question, we have a kona LHe running off FCP6 (new Mac Pro setup). Have just got to editing to tape (inserting to tape using the edit to tape function) and have found that more times than not the audio will not go out to tape but UV meters in FCP are showing levels (just no sound coming out of card). You can then do a restart of FCP and (sometimes) the audio will miraculously start working (no settings changed). It is frustrating to say the least. Does anyone have any suggestions (we have tried trashing the FCP prefs file).

Cheers,

andrew

what is the Kona Control Panel Say?

you have to choose to use embedded audio on the LHE models - the control panel defaults to AES audio out.

Thanks Gary, I'm pretty sure its set to embedded but will check on Monday. Just strange as it seems to output through all audio outputs when in timeline editing mode (i.e. just playing off timeline) but it is just when it flips into editing to tape that it mutes out. We managed to get it to output in the end.

We're still unsure of what the issue was, ...the only thing we can think of that was different in that project was that the editor had tried using the send to motion - send to FCP to round trip a motion graphic, even with rendering a new clip (and importing it as a stand alone animation) into that project (and replacing the motion project link) it still was weird.

The Solution: exported quicktime reference of timeline from dodgy project, created fresh new project, imported clip, dropped into new timeline, output to tape. That new project we did previews out with numerous times as well as a couple of test outputs to tape with, worked fine, no sign of the random sound muting issue, ...very strange, but at least that work around seems to work.

Cheers,

andrew
