The original version of the Todd-AO process used a frame rate of 26 frames per second, slightly faster than the 24 frames per second that was (and is) the customary standard. The difference does not seem great, but the sensitivity of the human eye to flickering declines steeply with frame rate and the small adjustment made the film appear noticeably less flickery, steadier, and smoother than standard processes.
Many epics and musicals of the 1950s and 1960s were shot in this format, including Oklahoma, South Pacific and Around the World in 80 Days. Films in the 1970s and 1980s like , Dune and Logan's Run used this process.
