iMovie export

[slipper]

OK so my last thread i was bitching about YouTube HD screwing up the sync of my audio and video. According to their help section, they prefer the use of MP3 audio files. How can i export using an MP3 audio file to satisfy YouTube? I was flipping thru all the different video formats, but no MP3. I usually export using MP4 and AAC

Are you using iMovie08 or 06? In 08, you should have the option to output to YouTube directly. I can't imagine that would create a file that wasn't compatible.

iMovie HD.

I usually export using 720p using Vimeos prefered settings. Never had any problems with YouTube until they switched to larger video players.

Can anyone help me here? How do you export using MP3 audio settings?
