[release2] “Why won’t the track matte animate like it’s supposed to?”
The short answer is it works much like that in version 2.0.
In 1.5 there is a convoluted recipe of importing Sequence 1 into a new sequence, duplicating tracks, reducing opacity of V2 so you could see V1 and it gave me a headache to animate the dam thing.
But it has been a year and the memory of the pain and the recipe has diminished. I hope someone can remember the sordid details.
