   \item I think the BRAW format is a video HDR format (e.g. takes each photo at multiple exposures).
   \item Natron can import BRAW, but requires propietary sdk bits.
+  \item Audio streaming via HDMI from camera works too.

   \item The 4k .mov works ok.
   \item Video .mov on device at 4k looks good played with mpv. But something is a bit off with colorspace, it is like looking thru an ND filter.
   \item Like Blackmagic RAW (.braw) doesn't work by default in debian, but the ProRes (.mov) does.
+  \item I can get HDMI out working. I can get 4K video recording to SD working with libre software.
+  \item Not working: 6K, due to it only recording to their proprietary format.
+  \item Not working: HDR (multi exposure per frame), due to it only recording to their proprietary format, afact.
+  \item Definitely not libre stuff.
+  \item But one of their formats is .mov, which ffmpeg, etc can read.
+  \item Their other format is .braw, their proprietary raw, which can't really be read libre.
+  \item One feature is interlacing of frames with different exposure levels.
+  \item So "in software"/postprocessing you can set exposure values with far more control.
+  \item And just better detail overall.
+  \item Canon has HDR still photo built into the camera.  Or on other cameras you can just do 3 (or whatever) then use software such as darkdable to make the final image.
+  \item The Blackmagic has HDR Still Image, .dng, that rawtherapee can read, but nothng else i tried can.(edited)
