How to get value from Source Text and assign to keyframes?

[Dan Ebberts]

The scale expression might be like this (for linear keyframes):

txt1 = comp("Control").layer("first keyframe").text.sourceText;
txt2 = comp("Control").layer("second keyframe").text.sourceText;
s1 = parseFloat(txt1);
s2 = parseFloat(txt2)
linear(time,key(1).time,key(2).time,[s1,s1],[s2,s2]);

The linear wipe expression could be similar, but it might be more complicated, depending on what kind of ease the keyframes have.

Thank you so much Dan

And how it would be applied in rotation, sorry .

I’m in my first steps in this.
