BRAW not supported anymore in Premiere Pro?

You are using the new "gen 5" firmware in your camera from BlackMagic, which is a complete rewrite of the code of the files. So all the other vendors have to updgrade/rewrite their code that works with the gen 5 firmware cameras. I'm still on gen 4, so BRAW plugins work fine in the shipping version.

Adobe has done that and is testing the new code in their public beta version, prior to releasing it into the shipping version. As one would hope they would do, to ensure that it works and is stable within itself and in working with the rest of the program on all sorts of gear.

I would expect a dot-update in the next few weeks for the shipping version would include the new code. In the meantime, the public beta currently out seems pretty stable here and for many. Or you can revert your camera to the gen 4 firmware from BlackMagic for a few weeks.

As the new BlackMagic gen 5 firmware mangled peaking and focusing for many lenses, it's already been replaced by I think two dot updates by BlackMagic. However, a couple lenses I use are still on the list of lenses which the gen 5 firmware cripples autofocus. So I've not updated yet, and hope BM gets that fixed in a new update of their firmware.
