Script to trim end point of layer when opacity is at 0%.
Hello all,
I’d like to create a script that looks a selected comp (or selected layers), and trims the end point of each layer when the opacity is at 0%.
The context is Power Point presentations. I have the slides on a time line, each with an expression that looks at a .csv file, turning the opacity to 0% when timeToCurrentFormat() reaches the specified time.
The expression:
f=footage(“TimeCode.csv”).dataValue([1,index-1]);
s=timeToCurrentFormat();
if (s<f)100; else 0;
<font face=”inherit”>The expression works great, the only issue is the render time. Some of these are 100+ layers, and I feel they would render much more quickly if the end points were trimmed so the expression on each layer wasn’t running the whole time it renders. Of course I could do it </font>manually<font face=”inherit”>, but that too takes a fair amount of time.</font>
<font face=”inherit”>Any ideas?</font>
Thanks in advance,
Kyle

Your question is very broad; that would definitely be something that you could script. Either to create the comp from scratch given the CSV, or to trim the ends based on the opacity. https://docs.aenhancers.com is the place to go for extendscript documentation.

I’ve written a script for this some time ago:
it checks if the first and/or last keyframe of opacity and/or scale == 0 and trims to those points.
Here it is:
Choinks – date modified is 2008, I’m getting really old 😉
Still works though!

Oops, but that does mean you’d have to create keyframes though.

Thanks Filip, I’ll check this out. I usually always gain some new knowledge from scripts, even if the scenario isn’t exactly right.
