Works like a charm Dan. If you had any sticky karma, it’s just went up in smoke.
I’m gonna look this expression over and maybe ask some questions about how it works later today.
Big thanks!

[Dan Ebberts] The other possibility would be to just check the times of the first and last keyframes, and make the opacity 100 if the current time is between those two times. Will that work?”
Either one would work. Paste Mocha Mask creates only one contiguous set of keyframes for each mask, so the first and last approach makes sense.

Yes! and 0 when there are no keyframes on the path.
The functionality I need is to have the absence/presence/absence of Mask Path keyframes flip opacity of the mask from 0 to 100 to 0.

[Dan Ebberts] “The expression should give you 100% if the path has any keyframes. Is that what you wanted?”
opacity = 100 when there is a mask path keyframe and 0 when there is not, for every frame.
CS6 has issues with paste mocha mask which is why I’m working in CS 5.5 for now. I’ll try in 6.0…

Thanks Dan,
Started my quest on your site, small world! I pasted into the Mask Opacity expression but no go. Mask opacity stays at 100. Am I missing something?

5 years later… but I needed the answer and so here it is. Running CS5, my objective was to be able to make precise subpixel adjustments while staying at a reasonable zoom, 200% to 400%. There’s no keyboard shortcut for sub pixel at 100% zoom, only at greater magnification do the arrow keys become more precise – 200% = ,5 pixles, 400% = .2 pixles and so on. So the workaround is pretty simple. If your comp window is at 200% or whatever, open a new comp window, detach it and zoom it in to whatever suppixel increment is needed. When the new comp window is active, the arrow keys will make subpixel adjustments and both comp windows will update. I found it helpful to drag the new comp window small and move it away from my work area so it wouldn’t be distracting.
