hey all,
think I may have stumbled onto a “more accurate” way of getting DNGs from DJI drones into d-gamut/d-log. I’ve been doing more or less @finnjaeger 's method described above for many years in Resolve of just debayering it in P3 D60/linear, but it always seemed less than ideal to me since d-gamut should really be D65 according to the docs, and after having a hell of a time roundtripping this stuff with another vendor I finally did a deep google and had a bit of a eureka moment that I had to share with some fellow nerds.
basically, resolve can indeed debayer straight to d-gamut/d-log, but the camera model EXIF info that DJI is putting in the DNG headers is not what Resolve wants it to be, so it doesn’t detect it as DJI footage and you only get P3/Rec 709/sRGB options. If you just change that exif tag, Resolve can detect it as d-gamut/d-log on import.
On the inspire 3 all it takes is stripping the “DJI” from the UniqueCameraModel tag. For example, if I look up the Unique Camera Model for one of the DNGs in exiftool I get:
Unique Camera Model : DJI FC4280
If you set this to be FC4280 then when you pull it into resolve it will give you d-gamut and d-log options in camera raw. very easy with exiftool:
./exiftool -UniqueCameraModel=FC4280 -m /path/to/DNG/frames
Be careful since this will actually modify your source files, I did it to dupes, but lo and behold:
