BMD provided the plugins for Braw to both avid and Premiere. But it’s not possible to make one for fcp without Apple’s permission. A BMD said some time ago.
Apart from this, I can only speculate that Apple’s arrangement giving atomos exclusivity is a hindrance because If BMD opens resolve to PPraw it will in fact give the external recorders market to atomos or at least a large portion that will also affect its camera division.
Don’t know if you know that atomos was founded by an ex bmd employee and after a failed lawsuit there is bad blood between both companies.
Why did Apple give atomos exclusivity? maybe because they could shoot two birds with one bullet. 1, make PPraw available to all . 2, Hold braw back. All without showing their teeth.
