MOGRT Media Repalcement Playback Issue

[Amozza]

I'm having an issue in Premiere (v22.6.3) with playback of a video clip that was replaced in a MOGRT that was created in AE (v22.6.). Here are the details.

• Main comp called "mogrt-comp" with various text layers and shapes. A number of properties from these layers are added to the Essential Graphics for this comp.
• Comp called "video-bg-15s" that just has one layer, a video clip that runs for about 16s. No effects or expressions added. This layer is added to the "mogrt-comp" EG as the Media Replacement.
• Comp called "video-bg-60s" contains four intances of the "video-bg-15s" comp staggered so they overlap. Instances 2, 3, and 4 have a 1s fade in at the beginning (image below for reference). This comp serves as a 60s loop of the single 15s video clip comp and is added to the main "mogrt-comp".
  

  

• All comps are 60s long.

In AE, when I add the "mogrt-comp" to a new comp and use its Essential Properties to replace the media , all works great. The new video background plays all the way from 0-60s.

In Premiere, when I add the MOGRT to the timeline and replace the media, only the first ~16s plays back (which I presume is the end of first instance of the video clip replacement). After ~16s , there is a still frame of the new video background. It's the correct video,  but a still frame from ~16-60s

Is this an error/bug or intended behavior/limitation of the MOGRT in Premiere?

[Mylenium · Accepted solution]

This is as it should be. Media replacement uses the properties of the original layer and if it isn't long enough it will simply stop at the end. Premiere has no way of looking deeper into the AE project structure. Nothing wrong here. So yes, it's a limitation.

Thanks for the info, Mylenium. Is there any way to use a loop expression to "trick" the clip into playing longer? 

[Mylenium]

There is no trick. Expressions can't do anything you cannot do with regular functions and using time-remap expressions or any of that would have it's own caveats. So no, it's not possible. You realyl have to design your templates differently with those limitations in mind.
