Following this tutorial I managed to create high quality gifs in reasonable memory size.
Using piping, what I'm currently doing is this
# Generate palette
ffmpeg -y -i - -vf fps=15,scale=600:-1:flags=lanczos,palettegen some_dir/palette.png
# Generate gif using palette
ffmpeg -y -i - -i some_dir/palette.png -filter_complex fps=15,scale=600:-1:flags=lanczos[x];[x][1:v]paletteuse output.gif
This is working great, but I read in the tutorial above that it is possible to generate a different palette for EVERY frame, how can I do that ? (Generate and use different palette for every frame)

Did you mean out.gif? Because running this command with
out.gifresulted me in the following errorError initializing filter 'palettegen' with args 'stats_mode=single' Error initializing complex filters. Invalid argument– bluesummers – 2017-08-09T10:53:08.950Your ffmpeg is prahistoric. – Paul B. Mahol – 2017-08-10T11:36:31.827
ffmpeg version 2.8.11not good enough? – bluesummers – 2017-08-10T11:40:35.630This actually works in ffmpeg 3.3.3 - accepted. How would you run it on a series of pictures instead of a video? – bluesummers – 2017-08-10T12:07:59.510
1By using image2 muxer?
ffmpeg.exe -i Wildlife.wmv -lavfi palettegen=stats_mode=single[pal],[0:v][pal]paletteuse=new=1 out%04d.png? – Paul B. Mahol – 2017-08-10T15:32:12.757@PaulB.Mahol thanx for the solution! Is it possible to generate 1 palette per, let's say, 30 frames? Because it seems like the performance is terrible when generating palette for each frame. – Alexander Korzhykov – 2017-08-18T19:43:09.503
