  • Interoperability in Digital Camera Capture

    The CinemaDNG Initiative

    April 12, 2011 NAB 2011, Las Vegas

  • Welcome

      Introductions

      Today’s program

      Background for the CinemaDNG Initiative

      Leading vendors supporting CinemaDNG

      Q & A


  • Lars Borg | Principal Scientist, Adobe [email protected]

    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


    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


    Cinematography Workflows with Multiple RAW Formats

    Vendor RAW


    Each application must read many file formats











  • Adding CinemaDNG to Cinematography Workflows

    Connect all products through one file format

    Capture in Vendor RAW or


    Ingest CinemaDNG


    Deliver in CinemaDNG


  • 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

      The only open alternative to proprietary RAW format


  • Example Workflow - Camera to Academy IIF

    Capture RAW data Ingest to IIF

    Deliver in CinemaDNG

    Edit in RGB

    Grade in CinemaDNG

  • The Promise of The CinemaDNG File Format


      An open, unified RAW image format for motion picture capture   Retains the user benefits found in proprietary RAW formats   Adds Interoperability, Metadata, Longevity

  • 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.
