"In fact, Sleeping Beauty, was the second film in history to undergo this extensive computer restoration process." (The first being the 1994 release of Snow White.)

Maybe not entirely... but 'extensive' is a troubling word.

Edit: I think the point they are making is the restoration was DONE for the 1994 release, not started in 1994.

I found the press release from June 24, 1993 (20 years ago to the day!):

Disney Classic 'Snow White' Undergoes Complete Digital Restoration at Kodak Facility

Nearly 120,000 frames of 35 mm motion picture film were restored. Each frame contained approximately 40 megabytes of digital data, roughly the entire storage capacity of some desktop computers.

In the course of searching I also came across an article that said the scanner ran at 3 seconds per frame, so that would be 100 hours of ingest time alone.
