How 3D Works
   Left eye sees one view
   Right eye sees a slightly different view
   Our brain puts them together and creates the depth of field
   3D movies use this method – using two masters
      Left Eye image
      Right Eye image




                  Left Eye                       Right Eye
How 3D Works
   To make our brains think we’re seeing 3D,
      Our left eye must see the Left Eye image
      Our right eye must see the Right Eye image


   We don’t have to see these exactly at the same time because of a
    phenomenon called, “persistence of vision”
      When a human eye sees images, the eye retains an image for about
       1/30th to 1/32nd of second before it processes the next image that it sees
      The holdover from one eye mixes with the other eye and we can’t tell they
       are appearing at different times

   So the key to getting 3D to work is
        Make sure the left eye sees the left view
        Make sure the right eye sees the right view

        Sounds simple enough!
How Does 3D Work?

   Together, through the glasses, your brain makes the various objects
    appear to have different depth




                               +                            =

How Does 3D Work?
   Horizontal distance between
    the same object in left eye vs.
    right eye creates the depth
    effect
   Screen size is important – the
    smaller the screen the less
    pronounced 3D effects are
   Viewing distance plays a part –
    the further away from the
    screen you sit, the more “3D”
    the objects become

Making 3D Masters
   Masters are created specifically for viewing environment
   Digital Cinema Projectors are different than Home Video Televisions
   Home Video Masters are color-corrected specifically for this limited
    range of colors while still maintaining the proper “look” of the movie
   You can’t use a DCinema Master for the Home or Vice Versa



                                 Digital Cinema allows for a wide range of
                                 colors to be displayed

                                 In contrast, Home Video monitors can
                                 only display a fraction of those colors
Making 3D Masters
   Color-correcting for 3D has an extra step
   Should factor in how the glasses might affect the overall
    brightness or color
   Filmmakers may brighten up the image to compensate
    for the glasses
Making 3D Masters
   Filmmakers know 3D for “Big Screen”
       Digital Cinema systems exist for viewing
       Standards exist
       Theatrical 3D presentations well-understood


   3D for Home is Wild, Wild West
     3D BD Specification was only finalized in December
     Filmmakers are hesitant to output Home Video masters without seeing
      their movie on the actual display
     Our existing 3D masters were made “in the dark”
     Recent focus on 3D for Home has brought many questions and
      concerns from filmmakers – we are working through issues
Making 3D Masters
“How will my vision translate to a smaller screen
  where people sit closer to the screen?”
                                   - Feature Animation Team



“Will the 3D depth settings I used translate- Pixar Team
  properly to a smaller screen or do I need to re-
  adjust the depth?”
                                          - Bruckheimer’s Team
“How will the glasses and displays affect my
  image? Do I need to compensate for them by
  re-color-correcting my movie?”
   Up until now, just because we released it in Digital Cinema, doesn’t mean
    we have masters for the home
   Starting with A Christmas Carol, we will have 3D masters for the home as
    part of the mastering process
   Pixar has NOT determined what they will do for their 3D masters for the
    home
   Multiple Ways to Make 3D Masters
There’s more than one 3D format

   Transport Formats
     Anaglyph
     Frame Compatible
     Frame Sequential
     2D   + Depth Map

   Display & Glasses
     Active
     Passive
     Autostereoscopic
Transport Formats - Anaglyph
   “Color-Filtering”
   Existing infrastructure
   Poor quality and color reproduction
Note: the example below is oversimplified & exaggerated for teaching purposes!
Transport Formats – Frame Compatible

   “Split Resolution”

   Side-by-side / Above-Below

   Existing Infrastructure

   Although each format is technically half the resolution of full HD 3D,
    each eye has more pixels than a 720p image

   Several Competing Formats/IP
        Sensio, Dolby, RealD

   Inconsistent User Experience
        System Menus
      3D Blu-ray format - Basic Split Resolution
      Side-by-Side in a 1920x1080 frame                Above-and-Below in a 1920x1080 frame


                                                                           L

Proprietary Split Resolution formats such as Sensio and RealD are based upon the formats shown above
