Hi,
I'm using Vegas Pro 16. I have two video tracks with a video event in each. Using Pan/crop, I have them move from from one side of the screen to the other, end to end. What I'm trying to do is blur the hard line of the overlapping event as it moves along (see screenshot). Of course I can achieve that with a blurred border effect but I just want the left and right sides to blur and not the top and bottom. I tried with a mask but it doesn't work. Is there a way to do this? I can't seem to figure it out.
