Mogrt in Premiere wont calculate Expression in Export

[Moritz Janknecht]

Hey everyone,

I just realised that when I export a project using my mogrt-lower third the elements wont scale properly, though they seem to be working perfectly in Premiere and the origin AE-Project.

Left: In Premiere
Right: After Export

Both After Effects and Premiere are up to date (23.0), and the error occurs on several Windows 10 based systems.

The yellow box scales according to the text size. This is the used expression for rectangle path size:

var s=thisComp.layer("Instagram_Text");
var w=s.sourceRectAtTime(s.outPoint).width;
var h=s.sourceRectAtTime(s.outPoint).height;

[w+thisComp.layer("Slider Control").effect("Padding y")("Slider"),85.6+thisComp.layer("Slider Control").effect("Padding X")("Slider")];

 The expression for the position works similar:

var s=thisComp.layer("Instagram_Text");
var w=s.sourceRectAtTime(s.outPoint).width/2;
var h=s.sourceRectAtTime(s.outPoint).height/2;
var l=s.sourceRectAtTime(s.outPoint).left;
var t=s.sourceRectAtTime(s.outPoint).top;

[w+l,-29.6];

Any idea how to fix this issue?

You are referencing the out point, which simply won't evaluate in your triple-nested scenario. This is even mentioned in the docs somewhere if I'm not mistaken. You need to use a different methodology like dialing in the value with a slider that is actually part of the graphics template or enforce a continuous evaluation on the values themselves with valueAtTime().

Thanks a lot, that seems to have done it.
I must have skimmed over that part of the documentation.
