File Format Not Supported - on transferred project

Question

Hi,I've searched the web for solutions, and it looks like I can't find exactly the one I'm looking for including from the forum, but I may have missed it so please point me in the right direction.  I transferred a project backed up on Google Drive to my MacBook Air that was previously on another computer/hard drive (MacBook Pro).  I was able to link most of the missing files.  Except some are getting the error message "file format not supported."  The files do not appear in the media browser for supported files; only if I change/open up the funnel to All Files.  Some of the files are .avi and some are .mov.I tried renaming them or moving them to other folders.  But it seems like something is wrong with the file itself and how it was transferred or how it might be supported by the newer software?I am using the latest Adobe Premiere Pro CC version, but the original project could have been on a different version (made in 2016-2017).  Some answers online address missing presets.  Is that what it is?  How do I transfer those?  Please help.Thank you

Apple deprecated QuickTime back in 2013. Ideally, the day after they announced it we would have been converting all of our movie files to Apple ProRes or H264.

Do you have a Mac that’s still running macOS 10.12 Sierra and Premiere Pro CC2017? Hopefully so. If not, do you know how to install macOS on an external boot drive (an SSD drive inside a USB3 or USB-C enclosure works really well for this)? You can roll back your macOS relatively easily as long as your Mac isn’t so new that it can’t boot with Sierra. Installing CC2017 is going to be trickier in that I’m pretty sure that it won’t show up in Creative Cloud Desktop on a system with a clean install, but you may not need to. CC2018 may work for converting files with 2019 likely being your dead end.

Apple Compressor may help. The latest version includes Compatibility Detection (About incompatible media in Final Cut Pro X - Apple Support ). Even thought Apple’s documentation is all slanted toward making media compatible with Final Cut Pro X, the same holds true for making media compatible with Premiere Pro CC2018 and CC2019 under macOS High Sierra or newer.

That said, anything you open in QuickTime Player X under macOS 10.12 will show “Converting media” for anything that’s not compatible going forward. Let it convert and then save it (QuickTime Player will add “(converted)” to the filename.
