Thanks for the responses.
I almost purchased QT Pro but there seemed to be a higher-than-usual number of unhappy customers reporting in on the Apple site. Kind of made me gun shy. I do believe that these were mostly Windows users having issues.
Then I found out that it apparently won’t work as a plug-in in Vegas (or something) so I’d have to go through two steps instead of just rendering from the timeline. That’s not going to work.
I’ll see if I can send the client an AVI on hard drive.
Thanks again 🙂
