I'm working on video for music recitals. Programs are usually 1 hour long and I provide students with a DVD of their performance. I also make uploadable files of each song. I bracket each song on the timeline into a work area for exporting. One take for Quicktime and one for Flash and a third for audio alone. It takes forever. Is there a way to accomplish this in batch?
I've just run a test exporting off the PPro timeline into Canopus (now Grass Valley) ProCoder and it generated 3 different output formats automatically after the multiple targets had been set up before the first run.
The current version 3 is described at http://desktop.grassvalley.com/products/ProCoderSW/index.php
So it looks as if this might be a possible solution for you to investigate.
