Thanks for the replies.
Dave, thanks for the input on the AVI issue. I realized I had not checked that box and now it works. Thanks!
As far as the quicktime issue, I’ve been able to render those codecs (photojpeg and animation) just fine on other systems with the same free version of quicktime. In fact, I can render those in After Effects without problems on the same system. It’s just Vegas that has problems with it.
I’m going to try that alternate quicktime version posted and I’ll report back with the results.
