VMS 11 audio issue with .mov rendering

Is anyone rendering to .mov with good audio quality?

Using VMS 11 - I get the following results when running several tests:

1) My reference is when rendering to .wmv with the following audio details:
windows media audio 9.2
128kpbs, 44khz stereo CBR
The audio sounds great

2) However - if I render to .mov with the following selected:
qdesign music 2 at 48kbits/s or 24kbits/s
44.1KHz 16 bit depth stereo
The audio becomes thin and distorted when loud. The resulting file size is about the same at the wmv video (my reference above)

3) If I render to .mov with the following selected:
"IMA 4.1"... 44.1Khz 16bit depth stereo ...
The audio is very good ... but the resulting .mov file size is 40% larger than the 2 renderings mentioned above. I generate some long videos for web application and if the file is 40% larger - it is almost impossible to work with.

If I need a quality .mov render (video and audio) - is VMS the wrong product? I produce music teaching videos - and I use the .wmv format for my website ... and I would also like to generate .mov files for yet another website that uses Apple computers and final cut pro. The Final Cut Pro is having trouble working with my .wmv files that I submit.

thanks

You export in a way depending how you want to view the file. For example, you export differently for TV/DVD, differently for PC/web, and differently for sharing your video with another editor (you mentioned Final Cut editing).

So, if you just want to export in order to view the file on a PC, or upload to Youtube/vimeo, you export like this: http://eugenia.queru.com/2007/11/09/exporting-with-vegas-for-vimeo-hd/

If you want to share your video with other editor people for further editing, or archive your video, then you must export using an intermediate codec, and in that case you can use the freeware Avid DNxHD codec (freeware download, needs to be installed on both the PC and the Mac). Obviously, intermediate codecs don't lose any quality at all, but the filesizes are massive. But it's important to not lose quality when you archive or share between different editors who do different jobs in a project. So if you're trying to export a video from Vegas in order to incorporate it or edit it further on FCP, use DNxHD. Do expect massive sizes though.
