Because I'll forget how to do this...

Crop

crop=w:h:x:y

ffmpeg -i in.mp4 -filter:v "crop=900:700:0:50" out.mp4

Generate Palette

ffmpeg -y -i out.mp4 -vf fps=5,scale=600:-1:flags=lanczos,palettegen palette.png

Convert to gif

ffmpeg -i out.mp4 -i palette.png -filter_complex "fps=5,scale=600:-1:flags=lanczos[x];[x][1:v]paletteuse" out.gif
