Following on from http://blog.davidesp.com/archives/989 where basically I discovered that
- …you need not only GoPro Studio Premium (which gets you the CineformRAW codec) but also a little front-end utility (that you use instead of Studio Premium) called RAW4Pro. That utility gets you the correct colours and proper audio (‘Studio’ does not otherwise).
Using that solution, I obtained a 5.5 times reduction in file size, for a few-seconds test-clip where the color-chart was handheld against the landscape at the top of the hill. The file looked good in Resolve where I was able to grade it ok and of course could have used it to encode MOV-H264.
Equally the CineformRAW imported fine to Sony Vegas Pro 12, where I could grade it and export to MP4-H264 or whatever. Vegas did not recognize the original RAW (CinemaDNG) – I tried various ways, including Vegas’s Device Explorer, so CineformRAW is a useful workaround for this.
The CineformRAW generated by RAW4Pro in its [Fine] setting, according to its [?] button, produces 10-bit Log, which QuickTime player reports as as “Millions+”. I wonder, is there a way to get it to produce 12-bit?
I expect I will use CineformRAW to replace my existing RAW footage where I want to maintain full 2.5K resolution, gradeability but don’t have chromakey-level demands on resolution around edges etc. Not that I’ve yet tried such chromakeying, RAW or CineformRAW -based. As yet…
