You can't. Unfortunately this stuff isn't compatible with each other.
What?!? Mylenium is usually right, so I think he must have misunderstood the question.
You can totally bring markers from Premiere to After Effects!
And you don't even have to export anything.
In AE, go to File>Import>Import Premiere Pro Project
Pick your Premiere Project. (Choose all sequences or whatever - it shouldn't matter.)
If you've left markers on footage, audio, or really any assets on a track in Premiere, you will have markers on the respective layers in AE.
And, if you've got markers on your sequence in Premiere, they will show up as composition markers in AE.
Both of them work and work well.
Sorry, I said "import" too many times.
File>Import>Adobe Premiere Pro Project is the actual command.
I forgot to mention, if you have marker names, comments, and duration on your timeline markers in Premiere, ALL OF THAT comes through in the composition markers in AE too.
Thanks, @Szalam, but this is not what am looking for, this solution is good for a local work between two apps, but I was wanted a solution for a remote editing machine that can send me Premiere's Timeline markers, to use them via expressions in AE.
We are already using the method you mentioned, asking the editor to clear all the footage from the timeline and the project and to keep only one adjustment layer holding the markers on it, and then send us this project, but i was looking for an easier way to do this from marker panel, or File > Export > Markers.
Well, then Mylenium did understand your question after all!
