It also appears that the current Adobe Premiere cannot but the older Adobe Premiere could because these same files are referenced in projects that can no longer read them properly. I've tried El Cap and Sierra systems. Can't test Media Composer at the moment, though that would be logical.
Simply resaving with QT7 doesn't fix it, but "exporting" as new ProRes file does. One possible common trait is that the masters were made by Media Composer, but that's based on a limited sample set.
Is there a problem with older ProRes files not being compatible with the new ProRes codec? I did not think this 32-bit to 64-bit transition was a problem for ProRes files..
