VSE animated mask with scenes? Ok so in a nutshell, I want to make a video that has 2 pictures that overlap eachother, and the overlap is animated, like this:



The clips are in the VSE:  

And the blend file(with photos): https://www.dropbox.com/s/xiztxtvxtzmvm5n/Unicycle.zip?dl=0
But I want to add in a black line right where the 2 clips meet.
Help please?
There is no hard edge built in to the wipe effect. Only blur width. You could make a  black bar .PNG then use the Transform effect to rotate it at the same time. You could use this addon http://blenderartists.org/forum/showthread.php?280731-VSE-Transform-tool it makes interacting withe the VSE transforms much easier.
