Hi,
I'm using Magic Lantern to do RAW HDR video, and basically the camera takes
the video in RAW format and you extract the individual frames as DNG files.
When I import them into DT (actually I just import one frame to edit and
then call darktable-cli to export everything), there is no option to use
the normal profiled noise reduction (e.g. 60D ISO 3200). Is there any way
to use normal profiled noise reduction on these DNG files? The DNG files do
not store EXIF information so there is no aperture, ISO and shutter speed
details.
I've tried creating presets from using normal RAW files (.CR2) for each ISO
setting, but when I apply them, the module just applies the standard
poissonian distribution NR, which somehow just smudges the entire image
(perhaps there's too much noise and hot pixels that the module just wants
to remove everything).
So, is there any way to remove noise from these DNG files efficiently? I
don't need to remove all the hot pixels since there are tools in video
editing software that does that better, but it would be nice if there was a
way to remove noise from the DNG files before I export them and bring them
into a video editing software.
