CinemaDNG is an open standard. I am using a camera with CinemaDNG support. It came out around the time BM did the bait-and-switch. Another model came out a couple years later, also with CinemaDNG support. It shows that BM is using RED as an excuse to lock people in.
RED has a patent on compressed RAW. Apple tried to invalidate it but failed, so anyone who wants to use the concept of compressed RAW has to license it from RED.
CinemaDNG is not a compressed format. It is a directory with DNG files. DNG is an open raw photo format. Both DNG and CinemaDNG predate REDCODE.
My camera records 4K 12-bit CinemaDNG with no compression and is in the same price segment.
If BM, given options they had (which also include things like “pay RED” or “recall products”), chose to silently remove the support for CinemaDNG in cameras that they sold advertising CinemaDNG support, I doubt blaming RED is anything but a PR tactic.
