I am trying to convert a video to an animated gif, and I actually want it to have banding, so I'm trying to turn off dithering.

Here's what I've tried:

ffmpeg -ss 1:24 -t 2 -i *.mkv -filter_complex "[0:v] fps=15,scale=sws_dither=none:w=480:h=-1,split [a][b];[a] palettegen=max_colors=4:stats_mode=single [p];[b][p] paletteuse=new=1" avengers3.gif

Here's what the output from the above looks like:

It seems to me that definitely still has dithering, so how to turn it off?

It said in the docs that sws_dither is the flag to set to "none" to disable dithering - perhaps I'm passing that wrong?

https://ffmpeg.org/ffmpeg-scaler.html tells you the sws_dither is the dither algorithm whereas https://ffmpeg.org/ffmpeg-filters.html#paletteuse tells you to turn the dither off.

The answer to your question is to set

paletteuse=dither=none

BTW, http://blog.pkh.me/p/21-high-quality-gif-with-ffmpeg.html gives you the result of the paletteuse settings.

  • Thank you, that solved it. For future note, I needed to change paletteuse=new=1 to paletteuse=new=1:dither=none

  • Thanks for this; annoyingly the paletteuse docs don't list none as an option (confirmed they didn't on Nov 17 2020, either, just as a sanity check). 🤷‍♂️ It works though (in 4.3.2 at least).
