This probably belongs on the Wish List. Having admitted that, let's see if anybody knows of a workaround for what Adobe refers to as Keyframing of effects. That is, suppose I want to add the Watercolor Effect to a clip using AVS? Can do, yes, but the outcome is all or nothing. There appears to be no way to get the time-line to do the work for me, gradually increasing the effect as the frames move along. Perhaps moving the effect within the frame? Among the audio effects there are, it's true, dummy-proof things like fade-in or -out. But nothing anywhere whose rate of outcome I could really tweak. Maybe this kind of feature set would boost size and cost of AVS programs, to prohibitive levels. But I can wish.
