Animate AE slider in Premiere

[Mongelt]

I created a .mogrt file in AE and it has a slider that regulates the position of the shade. I thought I could animate it with keyframes in Premiere later but Effects window doesn't allow me to set keyframes there and keyframes on the timeline don't work. Does anyone have a solution for that?

The Essential Graphics Panel in AE or PPro doesn't allow its ptoperties to be keyframed. The workaround is to write Expressions into the Slider Control in such a way that it re-animates the animated property/properties affected by the Slider Control. There are related posts in the AE Forum - this may help you to get started -
