Nikon has released the new firmware version 3.20 for its full-frame mirrorless cameras
Nikon Z6 and Z7, which gives the cameras the ability to record footage externally in BRAW (Blackmagic RAW) using a
Blackmagic Assist 12G HDR Recorder.

With the new firmware update, the Nikon Z6 and Z7 can now record 12-bit 4K UltraHD/FullHD in both
ProRes RAW (when used with the Atomos Ninja V recorder) and Blackmagic RAW (when used with the Blackmagic Assist 5" and 7" 12G HDR recorder) using an external recorder connected via HDMI. In addition to RAW video output, 10-bit video recording is also supported in combination with N-LOG.
The Blackmagic Video Assist 12G HDR Monitor/Recorder 5" and 7" feature a 2,500 nits bright touch display with Wide Color Gamut (WCG) and record to SD cards via 12G-SDI and HDMI
2.0 connectors in formats up to 2160p/60 (DCI 4K), with codec options for recording to Apple ProRes
, Avid DNx and Blackmagic RAW. Back in June, a firmware update already enabled the compact full-frame camera
Sigma fp to record 4K BRAW using the Assist Recorder.
The new firmware 3.20 (macOS/Windows) can be found for the Nikon Z7
here and for the Nikon Z6
here, it brings besides the external BRAW support also a bugfixes. Soon, the recording of BRAW via Blackmagic Assist 12G should also be enabled for the two new models Nikon Z6 II and Z7 II via firmware update.

It should be noted, however, that in addition to the firmware update, both cameras (as well as the new versions Nikon Z6 II and Z7 II) still require an approximately 200 euros expensive activation of the video RAW output by a
Service Point -- from our point of view, a somewhat cumbersome procedure.
