Using the decay expression to slow down and stop the “screen roll” preset
Hi!
I am new to the forum, and only slightly experienced in AE. I am creating some text that uses the screen roll animation preset. What I want it to do is gradually slow down and stop, with the text landing in the center of the screen. The resulting effect (coupled with a scrolling film frame) looks like a roll of flickering film that slows to a stop. I have tried using “decay = 0.7;” and tried different values to adjust the speed of decay, which works, but not as I expected. It also never completely stops.
Is there a better way to do this?? Maybe a different way to keyframe the properties so it slows down? I have also tried keyframing the “frequency” and “multiplier” values with no luck.
I appreciate any advice you guys can give. I see from glancing through the forum that everyone is extremely knowledgeable, so please share some with me!
Thank you!

I don’t see a decay parameter in the screen roll preset expression. What’s the expression you’re looking at?

Hi, thanks for responding! I should have been more specific. In the expression window (not sure if that’s the right term) that you can change the code in – the “Animator-Y-position-2” property, I was trying to add in the code to slow it down.
Decay worked, but again, it only slowed down but didn’t stop. I’m probably trying to put it in the wrong place…?

Keyframe the multiplier to 0 to stop animation.
There is no decay variable, this may have appeared if you had applied another preset before settling on Screen Roll.

Wow, you were right. I had tried the effect a couple of times and not successfully cleared it from my text. I recreated it and applied the effect fresh, and keyframing the multiplier worked perfectly.
Thank you thank you thank you!
