PR PRO MOGRT video freeze issue

I'm working with a customizable MOGRT created from an After Effects. The project contains multiple precomposed media placeholders (e.g., "media 01", "media 02", etc.), each precomp includes a solid layer with time remapping enabled. Each placeholder is designed to be replaced by a video in Premiere Pro.

Here’s what I’ve done so far:

  • I precomposed each solid individually and enabled time remapping for all media placeholders.

  • I made sure that each placeholder is exactly 50 seconds long to match the main “Render” composition duration.

  • I exported the MOGRT and imported it into Premiere Pro.

  • I replaced each placeholder with a new video (1 minute or more) using the Essential Graphics panel.

Issues:

Only the first 5–6 videos play properly, the rest freeze and display only the first or last frame.

All media placeholders start playing from the beginning of the timeline, instead of starting from their respective position (e.g., "media 15" should start playing at 30 seconds, but instead it plays from frame Videos seem to freeze after playing even if the timeline has moved on.  Opacity-based or time remapping expressions didn’t solve the issue. I suspect the issue is that Premiere plays all media from the beginning regardless of time remapping, causing them to finish early and get stuck on their final frame.

What I need:

A working MOGRT setup or expression that ensures:

  • Each media only starts playing at its actual position in the timeline.

  • Each video plays from its own start (frame 0) when the timeline reaches the placeholder's position.

  • Once the placeholder duration ends, the video should not freeze, repeat, or display its final frame statically.

If there’s a specific expression or workaround that solves this properly (like linking time remap to comp time with offset), please help me recreate the correct setup.

Hi @Ali Hakimov, 

 

A couple of things that may be messing with your intended results... Media Replacement controls do not support Time Remapping, Time-based effects, and Trimming. They cannot be translated over to Premiere Pro. You should have seen this warning when you exported the Mogrt from After Effects. 



When you create a Media Replacement Control in AE, you are basically creating a container for new media to fill it in-- like an ice cube tray. The Dimensions, Duration, and Frame Rate for this container are defined by the media or comp you used to create the control. They are set and that's all that Premiere "sees" about this control once you are in Premiere. 
The caveat to this is that you can create Protected Regions on the Primary Comp which will enable Responsive Design Time. This will allow you to stretch or shrink your Mogrt in Premiere and will essentially make the duration of that media container longer or shorter. It will not speed up or slow down the footage though. 

As I mentioned above, Trimmed Layers are not seen in Premiere, but In Points are. So if you stagger the In-Point of the media you are using to make a Media Replacement Control in After Effects, this will be respected in Premiere Pro. 

 

So in this example above... I will make all of these Media Replacement Controls in AE.

Layer 1 control will start at 0:00 
Layer 2 control will start at 3:00
Layer 3 control will start at 4:09


Those In-Points will be respected in Premiere Pro.

Another trick: 
Double-click on the Media Replacement control in Premiere Pro to open up the secret timeline for that replaced clip. (I know! why is it secret?!?) 

Here you can do all kinds of things, like add effects, do speed ramp changes, even add multiple clips. It's another timeline. 

 

The part of the timeline without the danger stripes shows you how much time you have to fill with your new clip and also shows you when the clip's In-Point is -- in this case it is 10 seconds into the Mogrt and not at 0:00 because the In-Point in After Effects is 10:00 

 

You will see the last frame freeze if the clip is too short to fill the duration of the Media Replacement Control. Open the hidden timeline and move the clip into the active region / non-danger-striped area. 

 

 

Hope this helps give some more context and tools to help you understand and work within the design limitations of the feature. 

 

Cheers,

    The AfterEffects forum might actually have better help on this, as this is primarily a question of how to create the comp in Ae, so that the mogrt saved from it behaves as expected in Premiere.

     

    And hopefully a couple of the others here may pop in, that have more experience than I in Ae created mogrts. I do some on occasion, but can normally get by with what I can do in Premiere.
