You can use the famous Big Buck Bunny movie.
Simply pipe your ffmpeg into this:
ffmpeg -ss 23.5 -t 2.5 -i - -filter_complex "[0:v] fps=12,scale=300:-1,split [a][b];[a] palettegen [p];[b][p] paletteuse" artwork.gif
I used Pandela's awesome ffmpeg params:
ffmpeg -i "Big Buck Bunny (2008).mp4" \
-vf scale=1280x720:dst_format=rgb8 \
-c:v mjpeg -q:v 0 -f avi \
-c:a libmp3lame - | \
ffmpeg -i - -lavfi "[0:v]format=gbrp12le,scale=1280x721:dst_format=gbrp12be,scale=src_format=gbrp12le,scale=1280x720,setsar=1/1[out]" -map "[out]" -f avi -vcodec ffvhuff -q:v 0 - | \
ffmpeg -ss 23.5 -t 2.5 -i - -filter_complex "\
[0:v] fps=12,scale=300:-1,split [a][b];[a] palettegen [p];[b][p] paletteuse" artwork.gif
