The goal wasn't to promote software freedom but to ensure that anyone could simply download the DLLs and use it in their software without needing to sign an NDA, beg for permission or deal with patent bullshit.
The reality is that there is millions of dollars of R&D in the source code for this (primarily through stuff like camera calibration data, but also the maths in n the background) that they don't want ripped off by competitors.
Like I said, I do like BM's stuff. I was a Free Software puritan for a long time but when I started doing video stuff Resolve was just too tempting.
I don't believe CinemaDNG is affected by Red patents because it's basically just a folder of numerically sequenced '.dng' still images and DNG is an Adobe standard. You see other companies using it.
Note: I am not a lawyer and Red may well have tried to sue somehow, but the basics of CinemaDNG compression go back to JPEG T-81 from the 1990's.
I'm not intimate with the patent but from what I understand you're right, CinemaDNG is just a sequence of stills in a tarball. In which case it seems nuts that the patent office granted and upheld a patent covering that.
This doesn't check out. The Linux kernel has billions of dollars in R&D, and where is the obfuscation?
The state of FOSS NLE's is laughable. OpenShot is a mess.
What contributions to FOSS NLEs are you working on?
