Sleeping Beauty restoration

Disney Studios recently underwent an extensive restoration of the 1958 film Sleeping Beauty that was released last week on DVD and Blu-ray. The picture quality has been called "stellar" with "perfect contrast" and "awesome color levels."

video restoration details:
  • used original nitrate sequential Technicolor process negative
  • negative is 3 frames (RGB) of B&W film
  • separate RGB frames prevent longterm color fading
  • Technirama large format negative process was 35mm is size but called a 70mm format
  • used an anamorphic Delrama lens for a 2.55:1 aspect ratio
  • scanned with a 4K resolution
  • major frame damage and flaws were manually fixed
  • digital noise reduction (DNR) was used to remove grain and clean up image
  • 1080p MPEG-4 AVC encoding on a 50 GB Blu-ray with a bit rate that averages 35 Mbps

audio restoration details:
  • the 1958 original 3-track 35mm magnetic score recordings from UFA Studios in West Berlin
  • Peter Tchaikovsky's 1889 ballet score
  • the original soundtrack was 6-track
  • equalization and signal processing were used to remove noise, track hiss, and pops
  • surrounds are used for residual score and ambient effects
  • lossless DTS-HD Master Audio 7.1 on the Blu-ray

An incredible amount of care was put into the audio / visual restoration of Sleeping Beauty. The Blu-ray release also has an extensive amount of supplemental material. Let's hope Disney expends this amount of effort of all its future releases.
