One way Disney does this is to project live-action footage directly onto the animators' drawing boards.
The film also incorporated live-action footage and photographs.
Tied in to each story are other segments, told through live-action footage:
The animated characters explaining the subjects were super-imposed onto live-action footage of the subject matter.
The filming of live-action footage also helped contribute elements to the film's story.
The majority of the video is animated, with the only live-action footage being the guest celebrity appearances.
All live-action footage was scanned in high definition from its first-generation 35 mm film elements.
Much of the film used live-action footage which was then rotoscoped to produce an animated look.
Because the animation unit did not have access to location sound recording equipment, all of the live-action footage was shot silent.
This lesson is explained with live-action footage, some left over from Symbiosis.
