Comment (by art1):

 You could find DNG files (for next 7days) found on https://upload.slub-

 The files were produced to test FFV1 codec and are raw 4k. To produce 16
 -bit-RGB, try ff. instructions:

 $> ufraw-batch --noexif --out-depth=16 --output-type=tiff $i
 --output=tiff4k/$(basename $i ".dng").tiff;

 This should produce 16-bit TIFFs

 Then test it with ffmpeg:

 $> ffmpeg -threads 2 -f image2 -i tiff4k/AWEBA000245_%07d.tif -c:v ffv1
 -level 3 -g 1 -coder 1 -context 1 -slices 16 -slicecrc 1 -y

 Hope, it helps…

 (PS.: It would be wonderful if anyone could code direct DNG support :) )
