I am using Vegas 9. I just downloaded a 'Transparent Alpha Channel Loop' of a Scrolling Film.
When importing this QuickTime loop it shows as any other import. How do I get this clip to appear transparent to let another clip show thru - without applying the composite level which would effect the whole screen.
Could somebody please guide me thru step by step.
Thanks a lot.
