How does it compare to ffmpeg gif encoder ? Can it be used to compress well gif too ? How can it support thousands of colors, I thought GIF was limited to a 25

  >How can it support thousands of colors Temporal dithering. Also called FRC - frame rate control. You might not notice it, but if you are on a TN monitor right now (almost all non-professional monitors) this technique is being used to emulate 24 bit color. Most TN panels can only display 6 bits per channel.

    How cool ! That's why the GIF are so heavy it must be something like 100 FPS

  The quality is much higher than ffmpeg. Encoding is slower. GIF works like a canvas that can be painted on with 256 colors at a time. This encoder takes care to reuse existing colors on the canvas as efficiently as possible. Also most encoders generate ugly palettes (e.g. for a start throwing out 3 of 8 bits of precision) and use naive dithering. This one spends so much effort on getting optimial palettes, that if I were to get VC funding for it, I'd say it does machine learning.
