If you uninstall QuickTime because of the recent security warning you will not be able to play or see ProRes files in Premiere Pro CC, also you will not be able to see XAVCS files in BM Resolve 12.5. My fix worked below worked for me.
This is what I did:
- Uninstalled QT
- Downloaded a new QT version form Apple’s site
- During install pick ‘Custom’
- I unpicked the ‘Player’ but kept the ‘Essentials’.
- Finished the install process.
- Opened up Resolve 12.5 and Premiere Pro CC and it played my files and rendered the just fine.
I am on Windows 10 if that makes any difference.
I am not a security expert, do this at your own risk, but it is my understanding talking with Adobe that the QT player (mostly in a browser) is your biggest security risk, the codecs are not the concern (at least at this moment).
When I was at NAB I also talked with Dave Helmly at Adobe and he said they are working on a solution very soon (that is all he could say). I hope it is a 64 bit solution!
If you have a better solution, let me know below.
