The CinemaDNG File Format
From sensor data to final image
“Digital Inverse” Bayer matrix
Final image Still or Video
When processed in camera: - Original is lost - JPEG or Video workflow
When processed in post: - Original is preserved - RAW workflow
Raw digital sensor data
(magnified 100x) Image processing
pipeline
Most steps are “lossy”!
The RAW image
… captures the digital camera’s sensor data with no processing in the camera
Opportunity for better final quality
Excellent for green-screen work
70 % of professional photographers shoot RAW
But…
Proprietary image formats come and go – now at 200+
➜ The DNG format for still photography, CinemaDNG for motion
How do you stay fully connected with proprietary
formats?
Cinematography Workflows with Multiple RAW Formats
Vendor RAW
Formats
Each application must read many file formats
avi
mov
dpx

CinemaDNG Objectives
Define a universal, high-quality RAW motion picture camera file format
Using an open, documented format for digital RAW image data
Leveraging existing standards (DNG, MXF)
Unrestricted use
No patents, no intellectual property rights encumbrances
No license fees
No non-disclosure agreements
Free source code, software kits, tools
64 companies participating, including 21 camera vendors

Avid
We Love CinemaDNG!
Avid Supports The CinemaDNG Initiative
Avid’s goal is to be file format agnostic and open
Offer flexible support for file formats and codecs based on customer demand
Offer open interfaces for integration
Support standardization
Reasons we like CinemaDNG
It’s an open standard
It’s based on other open standards
A common format allows us to support more capture devices and applications
We are exploring how to best support CinemaDNG in Media Composer
One possibility is via Avid Media Access

Blackmagic Design
We Love CinemaDNG!
Adding to the long list of supported native camera and file formats as of NAB 2011 DaVinci Resolve now decodes CinemaDNG files. Using a GPU debayer developed by Blackmagic Design, Cinema DNG images can be previewed, played and graded in real time on a MacPro or Linux single GPU system. Live demonstrations can be seen at the Blackmagic Design stand, SL220.
