You're welcome Adam. I had no problems playing it apart from the squashed aspect ratio of 1.5 and the audio out of sync. Try creating a clean Export preset out of Vegas in the aspect ratio and frame rate the video was shot in, that usually does the trick.

I think it turned out to be a strange combination of both aspect ration and frame rate. I tried running it through every compression app I have, and nothing worked. Finally, I ended up just bringing the files into Premiere one by one, adjusting fps and aspect, re-aligning the audio and video tracks (they somehow got disassociated) and then rendering out from there.
Incredible hassle. I'm not sure why Vegas did this, as I was pretty explicit in my compression settings I thought. But this definitely turned me off from that product. Back to Premiere, the devil I know. *Adam Quirk* / Wreck & Salvage <http://wreckandsalv <http://wreckandsalvage.com> age.com> / qu...@wreckandsalva <mailto:quirk%40wreckandsalvage.com> ge.com / +1 551.208.4644 (m) / imbullemhead (aim) On Tue, Jan 6, 2009 at 7:15 PM, Rambos Locker <rambos_locker@ <mailto:rambos_locker%40people.net.au> people.net.au>wrote: > I suspect it's the aspect ratio or frame rate causing the problem.
