Media Replacement used in multiple comps in a Mogrt

I would like to replace one still in a After Effects project that is used in multiple comps, to save as a Mogrt. I have set up a menu that uses one of 12 comps at a time. Some of the comps use the same still, but I need to be able to use Media Replacement for that still while in Premiere.

I cant figure out how to make the ONE media replacement change in ALL of the comps.

Can you place the image in a precomp and then use that precomp in all your other comps?

That didn't work Mathias, but thanks for the suggestion.

I can do what I'm trying to do with text, by using an expression to tie all the text layers together. When I add the source text to the Essential Graphics window (Which will eventually be editable in the Mogrt in Premiere) that works great.

The problem is, I can't figure out how to point a Still (graphic) and tie THEM together, so I can add a Media Replacement (for that still) to the Essential Graphics window (Which I want to be replaceable in the Mogrt in Premiere) So the still changes in Multiple Comps.

I hope I'm explaining this enough, because it sure is hard to write what I mean. (HA)

I tried that. When I exported it as a mogrt, and opened the mogrt in Premiere, and clicked on Media Replacement, it only changed the one that I dragged to the Essentials Graphics window in AE. Maybe I'm doing it wrong.

It works with text because I can use an expression to tie them together, but not with a graphic.

What Mathias suggested above works fine for me. If you are precomposing, make sure you precompose first, and only then drag the footage layer inside the precomp to the EG panel, so that Essential Graphics is referencing the correct layer. This means that everywhere you use the precomp as a layer in your template will point back to the one comp that has your media replacement layer in it.

If, on the other hand, you were to add the footage layer to EG and then precompose it, then the EG panel would now be referencing the nested precomp layer, not the footage that got precomposed inside it. This means that if you duplicate the layer or add the precomp as a layer elsewhere in your template, AE will only be referencing the original layer, and thus will only replace the media on that one layer. If I had to guess I'd bet this is what happened to you.

To check that you have the right media replacement property referenced in the EG panel, right click on that property in the EG panel and select "reveal in timeline". If it takes you to the footage layer inside the precomp, you should be good. However if this instead takes you to one of the nested precomp layers, then you need to remove that media replacement property from the EG panel and add it the right way by dragging in the footage layer from the precomp.

Select the still you want to use as the replacement inside the Project Panel. Hold Alt/Option Key and drag over the old still frame inside the project panel. All the instances of the old still will be replaced with the new image. Be sure that your new still matches size and resolution to avoid problems.

ANother way to do it is to select the old still and go to File > Replace Footage > File. Then select the new still and it will be replaced inside your project.

Jose, I'm in After Effects, trying to add the ability to add 1 still (graphic) to the Essential Graphics Window, so someone in Premiere (using this new Mogrt) could change 1 still, that's in multiple comps with 1 Media Replacement. I'm having trouble pointing all the still to each other.
