Just purchased a license and installed ProRes only on my Windows system. VC3 is the SMPTE name for DNxHD and using the term DNxHD needs to be licensed, but that is another matter. The same reason that it is called “Miraizon Pro Res” in the export settings.
But that being said, I exported several flavors of Miraizon ProRes as 422, 444, LT, etc. It may be my system as it was not the fastest encode, but all cores were active but never more than 40%.
Also, some applications can see it, and other not at this time. AS long as the application uses the MoviePlayer codec selection it is available. I tested with MPEG Streamclip, Redcine X Pro, QT Pro, and Media Composer, and was able to create the files. I was not able to export using DaVinci Resolve as it does not see the codec. That is something I will bring up with them.
All in all, naming aside, it’s a ProRes file and it’s nice being able to create such a file on Windows and worth the $49.
