1.33 or 4:3 = academy ratio. 1.43 = golden ratio. 1.5 or 3:2 = vistavision. 1.66 = European widescreen 1.85 or 1.9 = cinema flat 2:1 or 18:9 = univisium 2.20 = super panavision 2.39 = cinema scope 2.55 = cinerama 2.76 = ultra panavision

reference that moment before the screening staerts in whicvh the cinema projector adjusts its standard aspect ratio to the film's and you see projected black bars seamlessly shifting on the black-because-non-projected-on screen

I want to make a video piece consisting only in these variations of aspect ratio. continuosly adjusting aspect ratios - one morphing into another

make that moment/event the content of the film

talk to a projectionist, understand how that happens. it's an optical/mechanical adjustment of the projector right? i should then use a projector and make it constantly switch using different clips with different aspect ratios - dark room, all clips are black (but it's still light projected by the projector), white projection screen
