MakkE, that's still effective 24fps, since tripled frames are identical (no new motion is derived or interpolated). As it says on the page you linked to, it is to reduce the flicker:
And further down:
Afterimage = persistence of vision.
Just to clarify my point, max fps you see is limited by your display's refresh rate; am not debating the responsiveness of playing at higher fps.
Quote:You have a fluid film with 24 fps. The film roll has to roll thru the projector. To not see it rolling you have to make the picture black while the film rolls on. You would have to blacken the screen 24 times per second. But 24 black moments are too visible. Thus you have smooth motions but flicker. The solution is: Show each frame 3 times and make the screen black 3 times per frame
And further down:
Quote:The reasons for the results of Test 2 and Test 3 are afterimages. Bright light creates an afterimage in the eye. The same way you see light in your eye seconds AFTER the doctor shined a light into it. This afterlight makes it possible to see what was there seconds ago. The brightness of the afterimage of the cinema canvas produces such afterimages and thus helps the movie to be flickerfree.
