What is CinemaDNG?
CinemaDNG is a RAW digital cinematography format. It is an extension of DNG photography format, a RAW “digital negative” developed by Adobe.
Technically, CinemaDNG file format is based on TIFF containers.
In 2013, BlackMagic has launched a line of cinema cameras using CinemaDNG format.
Despite developing grading and editing tools for it, no other manufacturer showed interest, and CinemaDNG failed to become an industry standard.
A few years later, Blackmagic developed its own RAW cinema format. CinemaDNG was phased out.
Detection and Preview
Treasured (since version 3) can detect and preview CinemaDNG footage in corrupt files, in cards and hard disks.
Since CinemaDNG is a open standard still in development, Treasured may not support rare or new flavors of CinemaDNG. Flavors supported as of today are listed below:
Vendor: BlackMagic
Models: Pocket Cinema Camera1, Cinema Camera 2, Production Camera 3
Status: Treasured detects and previews
1BMPCC footage doesn't preview correctly due to a bug in OS X DNG renderer. Pending fix by Apple
2BMCC footage is called 2.5K by BlackMagic, but actual resolution is 2400x1350
3BMPC shipped in January 2014
Note that those cameras are also capable of recording in other video formats like ProRes and DNxHD.
Vendor: Magic Lantern RAW footage converted to CinemaDNG Models: Canon EOS 5D Mark II, 5D Mark III, 60D, 7D Status: Treasured detects and previews
Repairability
A CinemaDNG repair consists in scanning a card or disk, then detecting all the RAW frames present, and output them in folders.
Each frame corresponds to a .dng file. The collection of frames inside a folder corresponds to a clip.
Aero Quartet engineers develop a Repair Kit with the following features:
- Repaired footage has same quality as originally recorded
- Repaired footage is compatible with RAW workflows
- Metadata contained inside each frame is recovered as well
