I'm trying to make a scrolling credit box in Vegas Pro 16 for use in DVD A, but I want to have the DVD A background show through the Graphics box. That is, I want the rendered video to keep the Alpha channel transparency information.
I'm using the text credit scroll with transparent background in Vegas which works fine, it's transparent on the timeline. However, when I render it using uncompressed AVI with Alpha channel, it creates a scrolling text box with black instead of transparent for the background.
Any thoughts on how to do this?
