So this is a scary thing, Apple has killed Quicktime for Windows, and it currently has major security flaws in it, so if your computer is attached to the internet you should uninstall it.
The problem is that there are many video formats that require Quicktime to run. This includes all forms of ProRes, which has even become a major camera format, as well as Animation (a major format for After Effects) and DNxHD/HR.
Now Adobe says they are working on it, but will likely have to license components to get these to work, so if it ever does it will take a while.
Overall while this seems like a very Apple thing to do, it makes me once again worry about Apple and it’s future in Video. The thing is even if you are not going to release your software for Windows, you want the video to be able to run for cross compatibility, like AVID always released versions of it’s drivers for people who didn’t own AVID. And ProRES is such a great format that it has become a defacto standard across a lot of the Post Production industry, but with this action ProRES will slowly be relegated to a sidestory, In the future cameras are going to be less likely to support it, and eventually it will be a FCP only format (that is if Apple even keeps developing FCP X in the future). Other than the short term why would Adobe support it, if it is literally only able to work on a Mac, that is less than half it’s market, so why bother.
This just shows me how out of touch Apple really is.
