Mazze Aderhold, member of the Colormeup! team found a very tricky way to make the new codec PRORES 4444 XQ easy available.
In his example he copies the new codec from Final Cut Pro – X and pastes it into the quicktime folder in the library.
From his Blog:
so.. the new Apple ProRes 4444 XQ is out and there’s quite a lot of people wanting to get hands on it with their favourite editing-, grading-, or encoding application. Now there’s a couple of tools, that already include the codec – but they install it in a way, that only those tools can make use out of it.
Tools, that rely on the standard Quicktime library (to be found in /Library/Quicktime), will not see the codec as an option, when encoding to Quicktime. Also, many people install Apple’s ProApps codec-pack and are wondering where their XQ-flavour is.
Reason for that is simply, that ProRes XQ is not included with ProApps.
So what we will do, is find an application that includes ProRes 4444 XQ, and extract the codec from there in order to copy it the the general Quicktime Library, hence making it available to all applications that use the general Quicktime Library – such as Adobe tools, Quicktime Pro, or Assimilate SCRATCH.
