<P> Every shot in the film passed through the hands of eight different teams . The art department gave each shot its color scheme and general lighting . Under Craig Good, the layout department then placed the models in the shot, framed it by setting the location of the virtual camera, and programmed any camera movement . To make the medium feel as familiar as possible, they sought to stay within the limits of what might be done in a live - action film with real cameras, dollies, tripods, and cranes . Headed by directing animators Rich Quade and Ash Brannon, each shot went to the animation department from the layout . Lasseter opted against Disney's approach of assigning an animator to work on a character throughout a film, but made certain exceptions in scenes where he thought acting was particularly critical . The animators used the Menv program to set each character in the desired pose . Once a sequence of hand - built poses (or "keyframes") was created, the software would build poses for the frames in - between . The animators studied videotapes of the actors for inspiration, and Lasseter rejected automatic lip - syncing . To sync the characters' mouths and facial expressions to the actors' recorded voices, animators spent a week per 8 seconds of animation . </P> <P> Afterward, the animators would compile the scenes, and develop a new storyboard with the computer - animated characters . They then added shading, lighting, visual effects, and finally used 300 computer processors to render the film to its final design . Under Tom Porter, the shading team used RenderMan's shader language to create shader programs for each of a model's surfaces . A few surfaces in Toy Story came from real objects: a shader for the curtain fabric in Andy's room used a scan of actual cloth . Under Galyn Susman and Sharon Calahan, the lighting team orchestrated the final lighting of the shot after animation and shading . Each completed shot then went into rendering on a "render farm" of 117 Sun Microsystems computers that ran 24 hours a day . Finished animation emerged in a steady drip of around three minutes a week . Depending on its complexity, each frame took from 45 minutes up to 30 hours to render . The film required 800,000 machine hours and 114,240 frames of animation in total . There are over 77 minutes of animation spread across 1,561 shots . A camera team, aided by David DiFrancesco, recorded the frames onto film stock . Toy Story was rendered at a mere 1,536 by 922 pixels, with each of them corresponding to roughly a quarter - inch of screen area on a typical cinema screen . During post-production, the film was sent to Skywalker Sound, where the sound effects were mixed with the music score . </P> <P> Disney was concerned with Lasseter's position on the use of music . Unlike other Disney films of the time, Lasseter did not want the film to be a musical, saying it was a buddy film featuring "real toys ." Joss Whedon agreed, saying, "It would have been a really bad musical, because it's a buddy movie . It's about people who won't admit what they want, much less sing about it...Buddy movies are about sublimating, punching an arm,' I hate you .' It's not about open emotion ." However, Disney favored the musical format, claiming "Musicals are our orientation . Characters breaking into song is a great shorthand . It takes some of the onus off what they're asking for ." Disney and Pixar reached a compromise: the characters in Toy Story would not break into song, but the film would use non-diegetic songs over the action, as in The Graduate, to convey and amplify the emotions that Buzz and Woody were feeling . Disney and Lasseter tapped Randy Newman to compose the film . The edited Toy Story was due to Newman and Gary Rydstrom in late September 1995 for their final work on the score and sound design, respectively . </P> <P> Lasseter said, "His songs are touching, witty, and satirical, and he would deliver the emotional underpinning for every scene ." Newman wrote three original songs for the film; developing the film's signature song "You've Got a Friend in Me" in one day . </P>
