5d3 raw dng (black level issue?)

[cemanta]

Hello guys!  I'm having trouble with my RAW video. I'm using 5Diii 1.2.3 aug 7th build.

I have tried both MLRawViewer and RAWMagic Lite to get the DNGs, when the DNGs opened in Lightroom or Photoshop (or even AfterEffects) they could only see a bit of highlights.
Lightroom:

However, I can see the image without distortion in Preview (or Xee).

I've made some research in this site, but can't find anything related.
Appreciate if anyone can tell me what exactly this problem, and what is the best resolution.  Many thanks!

The black level is incorrect and needs to be set to 2048, e.g.:

Code: [Select]

exiftool -IFD0:BlackLevel=2048 *.dng
Some applications, like Preview, ignore the black level stored in the EXIF metadata and instead use a presumed value (which happens to be the correct value in this case).
