This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
gifify() { | |
if [[ -n "$1" ]]; then | |
if [[ $2 == '--good' ]]; then | |
ffmpeg -i $1 -r 10 -vcodec png out-static-%05d.png | |
time convert -verbose +dither -layers Optimize -resize 600x600\> out-static*.png GIF:- | gifsicle --colors 128 --delay=5 --loop --optimize=3 --multifile - > $1.gif | |
rm out-static*.png | |
else | |
ffmpeg -i $1 -s 600x400 -pix_fmt rgb24 -r 10 -f gif - | gifsicle --optimize=3 --delay=3 > $1.gif | |
