-delay 1x8 says that the animation should play a frame every 1/8 of a second. I have tons of Pages files lying around taking up precious space on my SSD.

-fuzz tells ImageMagick to treat pixels whose color values differ by less than 1% as the same color, giving the OptimizeTransparency action more pixels to chop away.

-f image2 selects the output format, a series of still images - make sure there are leading zeros in filename.Ĭonvert *.png -resize 70% newname%02d.png Convert mutliple filetype(s) into animated gifĬonvert -fuzz 1% -delay 1x8 *.png -coalesce -layers OptimizeTransparency animation.gif.

-s 480x270 tells FFmpeg to resize the video output to 480 by 270 pixels.
