as of cs6, you can use all manner of marker, but they will be converted to cue markers on the layer. there are scripts that will copy and paste, export etc, but you cannot elevate them to comp markers. I’ve heard that they are attempting to build the accessor for the Comp marker in CC, but I’ve really never needed that. So long as I can import other assets as layers, I can copy a layer to any comp I want, and I can copy the layer markers, I can essentially do all I need for audio. Getting disc markers to copy… …thats a tough one. I’ve never tried it. Supposedly the workflow is:
copy paste from one to the other in AE, then send the new comp to premiere, then new sequence from comp. But… …this may as well just plant the comp as a clip, and use the markers as clip markers…
It is possible to drag a sequence from one to the other, and I’ve not yet tried this. If the sequence already has the markers dropped on it, will they carry over when I drag only the sequence back to premiere? If so, then the markers would be there, I might just have to change their type. It would be good to test.
