Convert PPJ to PRPROJ

If any software can be used to convert or export .ppj files to .prproj, it is certainly Adobe Premiere Pro, the very same software from which both of these file types come from. Perhaps a simple resaving between the files is enough, but it might very well be possible that such conversion is actually not possible at all.

Everything points to the fact that ppj to prproj conversion pretty much describes importing of old Premiere projects (.ppj files) to one of the modern versions that features the latest project format (.prproj files).

If you have any issues with these file types or looking for a way how to convert ppj to prproj, it might best to contact Adobe support or some community forums related to Adobe Premiere Pro.
