identical in quality. The resolution of the footage available on the discs is 852x480 6000kbit/s at 29.97fps, which is well below the quality capable of IMAX film and Blu-ray media. The original IMAX film reel scanned in 2002 was massively cropped to about 20% of the original size. Several areas of the footage with important elements were cropped from view that would be seen during the ride. A 2D computer generated image of a DeLorean dashboard was also superimposed over the footage to reduce the viewing area to 60% of the 4:3 frame. The reel was also slightly damaged and has visible flicker during an end scene involving a volcano, as well as a frame jump during a scene with a prehistoric ice version of Hill Valley. It is currently unknown why the footage was cut down heavily from the original. Plot Following the events of Back to the Future Part III, Dr. Emmett "Doc" Brown moves to the present time in Hill Valley where, in 1991, he founded the Institute of Future Technology, a scientific institute specializing in his "futuristic" inventions. On May 2, 1991, he invites tourists into the facility as "volunteers" in order to test out his newest invention, the eight-passenger DeLorean time machine, by traveling one day into the future. Meanwhile, Doc travels to 2015 in the original DeLorean (a new time machine being built out of another DeLorean) to make sure the space time continuum is back to normal after the events of his previous time traveling adventures, while his other Institute scientists traveled to 1885 and 1955. However, in 1955, Biff Tannen stows away on the IFT scientists' time machine, hitching a ride back to the present-day Institute, which sets up the ride's main storyline. Queue Visitors to the Institute wait outside the facility. The queue video features clips from the Back to the Future trilogy, as well as new footage featuring Doc, diagrams for other innovations, ostensibly created by him, newsreel footage of him with Albert Einstein and other historical figures, and a "live" video feed from 2015 in which he explains the experiment. Pre-show Riders enter the ride as "volunteers" for the time travel experiment at the Institute of Future Technology. Doc explains that the plan was for them to travel one day into the future, but caution must be exercised as Biff, who graduated from Hill Valley High School in 1955,
