An FFGL effect that runs your clip through a film projector's gate, shutter and print, modelling the machine and letting the look follow. The clip is held at the projector's rate and only changes when the claw pulls down, in the dark. The light the shutter blades let through is integrated over each frame your display shows, so the flicker beats at the difference between the two rates. Each frame lands in the gate with its own correlated weave, and every mark belongs to either the print or the gate: scratches that stay put while the picture moves under them, dust that rides the print, a hair caught at the aperture, splices, reel-change cue dots, and dyes fading towards magenta.
This demo runs the plugin's shaders in your browser, so it needs JavaScript and WebGL2. The plugin itself, its source and its downloads are on its repository.
