I'm trying out Sony Vegas HD Platinum, and want to have an effect where in the middle of a video clip, I want to have a second video clip showing (in one corner, like a PiP effect). What I would like to is have the main video's audio fade out as the secondary video starts, then have it fade back in again when the secondary video ends. I know how to fade at the start and end of a video, but I can't see how to do it in the middle.
Anyone able to help? Thanks.
