Is the blue screen functional in svn 4679? I can't get it to work.
I have one clip on top of another, with a composite transition between them.
I apply the blue screen effect to the top clip, select a color key in the top clip using the dropper tool.
What I see happening is that none of the top clip appears over the bottom clip when the blue screen effect is enabled. Playing with the variance in the blue screen effect makes no difference. If I disable the blue screen effect in the top clip then all of the top clip appears over the bottom clip as expected.
What am I doing wrong?
