ExtendScript: Add Keyframe to Range Selector?

Posted by Breton Brander on January 21, 2023 at 4:23 am

Hi there!

I am trying to add a keyframe to this Range Selector using ExtendScript (see attached screenshot)

This seems simple, but I can’t find any documentation on it.

Any tips on how add or remove Range Selector keyframes in After Effects with ExtendScript?

Thank you very much!

Like this, I think:

var kfTime = 1;
var kfValue = 0;
var myLayer = app.project.activeItem.layer("My text");
myLayer.property("Text").property("Animators").property("Animator 1").property("Selectors").property("Range Selector 1").property("Start").setValueAtTime(kfTime,kfValue);

Thanks for the help Dan!

Your reply helped me figure out that my range selector was set to “Index” and that’s why I couldn’t access it with ExtendScript 🙂 (because the property was ‘hidden’)

Range Selector Percentage:

myLayer.property(“ADBE Text Properties”).property(“ADBE Text Animators”).property(“ADBE Text Animator”).property(“ADBE Text Selectors”).property(“ADBE Text Selector”).property(“ADBE Text Percent Start”)

Range Selector Index:

myLayer.property(“ADBE Text Properties”).property(“ADBE Text Animators”).property(“ADBE Text Animator”).property(“ADBE Text Selectors”).property(“ADBE Text Selector”).property(“ADBE Text Index Start”)
