Comment (by SeinopSys):
Correction to the command: the output is actually a result of the
following scale options:
{{{
ffmpeg -i dot.gif -lavfi "[0:v] scale=w=50:h=50:flags=lanczos,split
[a][b]; [a] palettegen [p]; [b][p] paletteuse" scaled.gif
}}}
I ended up copying the output under the wrong run, but the version and all
other information besides the input/output size is correct.
