Please add "paletteuse" filter, without it i can't make high quality gif animation.
You have "palettegen" filter, but not "paletteuse".
Or maybe you have some ideas how to make high quality gif animation without "grain" effect?
Examples:
1. Davinci default render (no "grain" effect)
2. VoukoderPro (with "grain") yuv444p - a little better, not enough
3. VoukoderPro (with "grain") yuv420p
