Here is what I'm trying to do...
1. Find a scene in a long avi file, and hit 's' to split it.
2. Seperate the split apart form each other by dragging the later portions away.
3. Fade out to black on the tail end of the earlier piece, fade up from black at the start of the later piece.
4. I've been inserting a '1' second long solid black backdrop inbetween the two.
Sometimes when I butt up the solid black to the preceeding fade out, by video FX disappears from the video.
Usually when this happens, I undo up to and including the split, move it a little, and try again.
There doesn't seem to be any rhyme or reason to this. What is going on???
