Many thanks, assume it can be done in with the other stills project.
There are a few considerations:
PrPro has a max pixel dimension of ~4096 pixels in the largest dimension. A couple of these should not be an issue with a stout computer, but you do not want THAT many or the Project WILL bog down. Were I working with more than about 3, I'd do each one in a separate Project, and then just Export, for Import into my "master" Project. I'd also Crop the vertical in PS to just what was needed for the Project's/Sequence's vertical Frame dimension.
Make sure that Scale to Frame is turned OFF, or odd things will likely happen.
I would do it in AEFX then bring it back into PPRO
