older version (2015) davinci resolve output files not readable in premiere pro CC v.22.0.0

What codec (compressor) are they?  In quicktime player, just load the file and hit command-i to get info...

Also, I know sometimes old video files do not have a file extension in their file name.  I've had issues where dv movs exported from an early version of fcp would not open in premiere, but if I added .mov to the file name, they would import...  probably a long shot, but I've learned sometime's it useful to just say it out loud.  

Hi Nohochman,

If it were me, I'd get those files up to a more current file format. For that, I'd first update Resolve (there is a security issue in older versions - we just heard about this), once it is current, open the project files in the new version - then attempt a migration to current Premiere Pro software.

Let us know if that works.

Thanks,
Kevin
