Print a clip on a till receipt. Every frame is reduced to pure black dots on paper-colored stock, with the rough stray dots of cheap thermal paper.
Dithering
Atkinson and Floyd–Steinberg represent gray as patterns of dots; Threshold cuts each pixel to black or white. Brightness and Contrast run before the dither and decide which midtones survive. If faces vanish into black, raise Brightness; if the frame washes out, raise Contrast.
Paper
Paper Tint picks the look of the stock: faded receipt paper, blue carbon, or stark black and white. Paper Noise adds stray ink before the dither, which turns into speckle across the frame.
1-bit video
A 1-bit frame is almost all edges, which is the hardest content for a video encoder. Expect more compression smearing at a given bitrate than on the source, and export at source size rather than scaling down.
