CineformRAW as Intermediate, Interchange and Archive Format for RAW (CinemaDNG) from BMCC

Following on from 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…
