Youtube audio sync
 

So I've read that this can be an issue getting the audio and video perfectly synced for youtube.

I've got a render that works perfectly in Vegas studio 9 and in the quicktime player after render, but after uploading to youtube it's a bit out of sync.
Not a lot, just a tiny bit, probably 20 miliseconds or so....that may not sound like a big deal
but I'm a perfectionist.

So, is it just a crap shoot with youtube? I uploaded 5 videos where I slid the audio back and forth to try to sync it, but it really didn't make a difference.

If there is some method to this madness...what is it.

I edited a .avi file (created from neoscene) and rendered it as:

Sony AVC .mp4
Bitrate: 15,000
Size: 1280 x 720 (for Youtube HD)

Audio mp3 at 256 48 khz.

Maybe my settings are higher than they need to be for the audio and the bit rate thus
creating too much for youtube to process?
