butting 2 events with fades without losing my fades….

I think the idea is that video has defined “boundaries” (i.e. either you have a frame or you don’t – you can’t have a 1/2 frame). With the audio there is no such boundary (or it is a much finer gradation), so your video may be 120 frames (4 seconds at 29.97 frames per second) long, but your audio may be the equivalent of 4.05 seconds, which does NOT correspond with a frame boundary.
