Multichannel audio not working on Google video upload

[Steven1621]

This problem is driving me mad, so I really hope there is someone here that knows the answer.

I edited a short film in Final Cut Pro. A boom mic was used with a Sony VX-2000 to take the footage. There are several channel of audio comprised of background music and such. When I export to a quicktime file and upload to Google video, some of the sound is missing. I've exported it a dozen different ways and still can't get it. Does anyone have an idea what is wrong and what I need to do?

Does the QT file that you export from FCP also lack some of the audio, or is it only after it's been uploaded? Are you performing an "Audio Mixdown" in FCP prior to exporting?

That would be my first thing to try. In FCP, go to Sequence->Render Only->Audio Mixdown (Command Option r).
