MP4 to GIF

Making GIFs that do not look terrible — the palette pass is the whole trick

GIF is a 1987 format with two hard limits: 256 colors per frame and no audio. Naïve converters map every frame to a generic web-safe palette, which is why so many GIFs have banded skies and blotchy faces. The fix is a two-pass encode: scan the actual frames you are about to use, generate a palette optimized for those colors, then apply it. That is exactly what this tool does (ffmpeg’s palettegen → paletteuse), and it is the single biggest quality difference between a good GIF and a bad one. Dithering is the second lever: ordered (Bayer) dithering scatters the error in a regular pattern that hides banding in gradients and is usually what you want; turning it off gives flatter, cleaner results for screenshots and UI captures with large solid areas. Beyond that, two settings decide your file size more than anything else — duration and frame rate. Because every frame is stored, a 10-second clip at 24 fps holds 240 frames; dropping to 10 fps cuts both the size and the smoothness roughly in half. Keep GIFs to 3–6 seconds for reactions and short product demos; if you need longer or want sound, use a real video format instead.
