One of the things that lets a gif down is obvious dithering. We can mitigate this by pre-processing the palette, then using it in the subsequent gif to find the best match rather than overplay our dither hand.

Take our [previous Python code](https://steemit.com/python/@makerhacks/how-to-create-animated-gifs-with-python) and tweak it thus:


```
# output the result
os.system('ffmpeg -framerate 24 -i frames/%03d.png -c:v ffv1 -r 24 -y out.avi')
os.system('ffmpeg -y -i out.avi -vf palettegen palette.png')
os.system('ffmpeg -y -i out.avi -i palette.png -lavfi paletteuse out.gif')
```

What we do here is take the AVI and extract a palette, which will look like this:

Then we use that palette to generate the gif.

You can see the difference here is subtle unless you zoom in:

But! you might find the higher quality *palette* version is smaller in file size!
