I have a client who want to include a slideshow with voice over, that he has made. And he want it to be his intro. Can I import Flash files into Vegas 4.0? How?
Don't waste a lot of time finding out that you CAN'T render to Quicktime.
What appears to be a render, is actually pointers, pointing back to the flash files in a Quicktime wrapper.
Render or export your Flash files as numbered still frames.
Vegas will import them as an animation. Try a test before you book a job, but it should work.
