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.
