I'm trying to make a short video with a transparent background (for my own overlays), all tutorials tell me to go into "options", and "enable Quicktime plugin", which I do... but then I never get the option to render as a Quicktime movie. The option doesn't come up in the "Render as..." screen.

What am I doing wrong? Anyone have an idea? Is it a different format now? (The tutorials I've been looking at aren't more than 5 months old)

I'm using Vegas Pro 18 (build 434)
