IMAX is projected at the same 24fps as 35mm. IMAX HD runs at 48fps but there were few programs photographed at this rate. Doug Trunbull's Showscan is 5 perf 70mm projected at 60fps. but this was mainly only seen in gimmicky ride-film motion seat venues and some pizza parlors in the 80's. Showscan is now bankrupt.
