{{short description|35 mm motion picture film formats}}

'''Maxivision 24''' and '''Maxivision 48''' are [35&nbsp;mm film](/source/35mm_movie_film) motion picture film formats. The system was designed by Dean Goodhill in 1999.<ref>{{Citation |last=Pannill |first=Shelley |date=Nov 27, 2000 |title=Film's Latest Picture Show |url=https://www.forbes.com/asap/2000/1127/153s1_print.html |work=Forbes Magazine }}.</ref> The system uses normal thirty-five millimetre motion picture film, capturing images on three perforations of film per frame. The format can run either at the standard twenty-four frames per second, or at forty-eight frames per second, which reduces [strobing](/source/Jerkiness) effects and increases apparent resolution when combined with a system for reducing film movement in the gate and eliminating scratching.

Because Maxivision uses only three [film perforations](/source/film_perforations) per frame, the twenty-four-frame-per-second format uses 25% less film than standard [four-perforation](/source/4_perf) formats, and the 48 frame-per-second format only requires a 50% increase in the amount of film to yield twice the frame rate. The image is exposed into the region ordinarily reserved for the analog [optical sound](/source/Sound-on-film) track which is rarely used now. This allows for a wider image on the same size film. This also reduces the need for cropping of the image and makes for a 30% larger total frame area than traditional projection even though less film is used.

The advancements of this system go beyond simply a larger image with less waste, however. The projector head is far more stable than traditional projection systems. It uses a sophisticated grid tracking [charge-coupled device](/source/charge-coupled_device) to automatically detect and compensate for any changes in the film type and position making projection of even traditional thirty-five millimeter prints sharper, more steady and with less chance of damage to the film.

Critic [Roger Ebert](/source/Roger_Ebert) repeatedly praised the system, saying that the picture quality is "four times as good" as traditional film projection, and "provides a picture of startling clarity."<ref>{{Citation |last=Ebert |first=Roger |date=May 27, 2009 |title=Roger Ebert's Journal: That's not the IMAX I grew up with |url=http://blogs.suntimes.com/ebert/2009/05/thats_not_the_imax_i_grew_up_w.html |archiveurl=https://web.archive.org/web/20110810092258/http://blogs.suntimes.com/ebert/2009/05/thats_not_the_imax_i_grew_up_w.html |archivedate=2011-08-10 |newspaper=Chicago Sun-Times }}.</ref><ref>{{Citation |last=Ebert |first=Roger |date=January 29, 2011 |title=Roger Ebert's Journal: After 3D, here is the future of film |url=http://blogs.suntimes.com/ebert/2011/01/more_than_ever_the_future_of_f.html |archiveurl=https://web.archive.org/web/20130406042108/http://blogs.suntimes.com/ebert/2011/01/more_than_ever_the_future_of_f.html |archivedate=2013-04-06 |newspaper=Chicago Sun-Times }}.</ref>

The format uses a custom-built projector head that can be switched between standard 35 millimeter formats and Maxivision. Furthermore, the new projector head is able to change from [anamorphic](/source/anamorphic) to Maxivision and standard matte prints on the fly. This reduces the chances of operator error and cuts the costs of having to order special trailers for different movie formats.
