Turn a clip into large pixels. The frame is divided into a grid of square blocks and each block is filled with the average color of what it covers. Small blocks give a low-resolution video game look; large ones reduce the picture to abstract color.
Pixel size
Pixel Size runs from 2 to 64, measured on a frame 800 pixels on its long edge and scaled to the real frame size. At 720p output a size of 8 gives 13 px blocks, about 100 across the width. Above 30 or so, detail is gone and only broad shapes and colors remain.
Retro palettes
Original Colors keeps each block’s true average. The palette options snap each block to the nearest color in a fixed set: Game Boy greens, CGA’s four colors, or the 16-color PICO-8, Commodore 64, and DB16 palettes. Combine a palette with a mid-sized block for a clip that looks like it came out of an 8-bit console.
Dithering spreads blocks between two palette colors where the source sits between them. It keeps gradients such as skies from turning into a single flat band, at the cost of more block flicker in motion.
Pixelating for privacy
A fully pixelated frame hides faces and text only if the blocks are large enough. Reconstruction from mild pixelation is possible when blocks are small relative to the feature, especially for text. For anything sensitive, use sizes of 30 and above so each face or line of text sits in a handful of blocks.
