Mogrt Timing Control in Premiere Pro?
Hi all,
I’m trying to build out a mogrt that’s essentially easily replicable animated powerpoint slides–the point being, I have a header and body copy. I’m trying to find a way to animate on the body text with a start point that’s able to be controlled by the end user, regardless of if they rate stretch the duration in Premiere. For example, if the narrator says a key word (the header), then four seconds later begins the actual definition, the user could input the number 4 and the animation would start 4 seconds after the composition begins.
I have it working if it isn’t rate stretched, but that isn’t very helpful in the end. I was hoping that if I programmed the animation start to be controlled by a slider value it would apply the linear() start time after the rate-stretching in Premiere, but it applies before so it’s the inputted value sped up or slowed down afterwards. And I can’t use protected regions, because I need the animation to potentially start and last for the entire duration of the clip
My main question is: is there a way to create a point like that in After Effects that shows up in Premiere and can be manipulated independently of the rate stretching?
I considered trying to use expressions tied to the position of markers–with the idea that the user could drag the marker position to where they want the animation to start–but in Pr 2025 the markers placed in Ae aren’t showing up in the Source Monitor in Premiere (for me), even though some Adobe support forum posts imply this has been something you’re able to see in the past.
At this point, I’m not sure if it’s actually not possible with the functions of the apps or if I’m just trying to go about it the wrong way and missing something obvious.
Thanks to anyone for advice on this.

I’ve never found time-stretched AeMoGRTs to work reliably in PPro. Instead of time-stretching in PPro, use cuts/edits in PPro on the AeMoGRT. Then ALT+Drag to create a duplicate and adjust accordingly. This will of course not work if you have elements within the AeMoGRT that animate continually.

Thanks! Somehow I didn’t think to do it that way–I was way overcomplicating it. Adding padding before the animation starts then placing a cut on it does mean I can endlessly stretch out the pre-animation part without having to use expressions. Awesome!

In PPro, its Frame Hold feature works well with AeMoGRTs. Pair that with edits on the AeMoGRTs at strategic points is far more productive and PPro Editors are accustomed to these tools – edit and Frame Hold tools.

Be aware that if you make a cut in mogrt, then you create N points to edit (if needed later), cause alt+drag creates a new instance of mogrt in a timeline. Plus, if there is any animation, it gets affected and no longer works as expected.
You can control this in Premiere, by adding a slider in AE, which defines animation start time (and ideally, duration how long it should last). Then, link your animation by interpolating from start time.
Things to keep in mind:
1. You need to make mogrt comp time in AE long enough to fit if user defines late start time.
2. You shall not use safety region (well, unless for intro), cause it does not work well with this approach. -
You’re right about protected regions getting in the way here. They lock the timing, so anything driven by a slider or time offset won’t behave the way you want once the clip is stretched.
For what it’s worth, I’ve been dealing with the same issue in my own MOGRTs, and I ended up creating a small script that builds the timing controls and expressions so the start point is fully driven by a slider in Premiere. It avoids linear() getting distorted by rate-stretching.
If you want to try it, you can test it for free and see if it helps with your setup.

Animate any property in After Effects without keyframes. Ideal for MOGRT creation and for those who are over the linear() function. It applies Penner easings and the right controls automatically..
