I am not presented with a Dolby Digital "Save As Type" when rendering a project using Vegas Pro 9, 64-bit. Is this a limitation of running the trial version?
Vegas Pro v8.1 presents this "Save As Type" option.
well, normally there's no mpeg or ac3 rendering/opening possible. Also, normally, if you already have a license & install a demo, it IS available in the demo. maybe it has something to do with the 64-bit version?
Do you have DVD Architect installed? Once upon a time, it was the DVD Architect installation that added AC3 encoding. I don't know if that's still true, or if the fact that you're using a trial is relevant.
"I have the option on trial version Vegas 9 64 bit - just did a render to AC3Pro - not problems."
Most likely because you already had DVDa installed.
The AC3 licensing is held withing DVDa which is not downloadable on trial versions. On the trials you can create AC3 on the time line and play with it a little but you will not be able to save AC3.
SCS confirmed that this is a known (but not publicly documented) limitation of the Vegas Pro 9 Trial.
This concern I have is that installing the Pro 9 Trial can make Dolby Digital unavailable in Vegas Pro 8 (apparently a licensing-related issue as Dolby Digital's availability in Vegas is dependent on the DVD-A license, and this is probably why the licensed version of Pro 9 includes a new DVD-A license <as not to impact the ability of Pro 8 to use Dolby Digital>)
The solution for me was to uninstall the Vegas Pro 9 trial to get Dolby Digital again operational in Vegas 8.1
