I suppose ffmpeg is the weapon of choice but I didn't find out how to reach my goal.

From here:

ffmpeg -i input.webm -pix_fmt rgb24 output.gif

    @BarafuAlbino Thanks buddy, but I got an error: "Unknown pixel format requested: rgb16." – brubaker Aug 4 '14 at 12:01

    @brubaker I think I got you beat: 120K .webm → 2.7G .gif. Yes, that's with a G. – wchargin Nov 1 '15 at 23:19

    rgb24 is not supported for gif, ffmpeg would use rgb8 instead automatically. – kxxoling Jan 22 '17 at 8:59

Barafu's answer is alright. But, I resulting gif may have color conversion issue as ffmpeg complains on Incompatible pixel format 'rgb24' for codec 'gif'. Here is what I find works:

First, create PNG Palette:

ffmpeg -y -i input.webm -vf palettegen palette.png

Then, use the palette to produce gif:

ffmpeg -y -i input.webm -i palette.png -filter_complex paletteuse -r 10 output.gif

  • produced a much better result in my case than the accepted answer – Eugene Jul 15 at 9:42
