I'm editing a video that has a number of cuts from one video stream to another. This was created using Excalibur. Now I'm trying to go back and add some titles, etc., and want some transitions (crossfades) at some points. However, I couldn't get some of these transitions to work - the effect I see is a cut.
I expanded the video track to show the A/B roll. When I did that, I found that the places where it wouldn't work had the same video track on both the A and the B, with crosshatches (actually, I guess, diagonal lines) on one of the tracks. What are these? How do I fix it so I can do a crossfade?
Thanks.
