Dan, assistance with your strobe dissolve expression
I found this post on “strobe dissolve” expression you wrote.

I love it. It’s just what I’m looking for.However
I’m trying to get it to work for me and I’m not understanding the expression well enough to change it.It’s the hold time I feel like I have no control over.
I want to time stretch to 150%, posterize time = 1, that makes the frame hold for about a second and a half.
and fade time to .5It doesn’t seem to be working.
timeStretch = 150; // layer time strech (percent)
fadeTime = .5; //fade time (seconds)holdTime = (1/effect(“Posterize Time”).param(“Frame Rate”))*timeStretch/100;
t = time % holdTime;
fadeStart = holdTime – fadeTime;
linear(t,fadeStart,holdTime,100,0)Is there something I’m doing wrong?

Possibly. 🙂
Did you duplicate the layer (after the time stretch and posterize time effect, but before the expression is applied), apply the expression to the top copy, move the time indicator to where the first frame starts to fade (1:01 on my footage – watch the opacity value), turn off the visibility of the top layer and move the bottom layer so that the 2nd frame just appears at the time marker and then turn the top layer back on?
It seems to work for me.
