MP4 to GIF

As my last post covered unshaking and stabilizing videos, this post now deals with converting those videos from mp4 to gif (to create stunning looped images).

first we need to run a command to export the frames from the mp4 file.

mkdir frames
ffmpeg -i vid.mp4 -vf scale=320:-1:flags=lanczos,fps=10 frames/ffout%06d.png

This will create a couple of files which we'll need in the next step to create the gif.

convert -loop 0 frames/ffout*.png out.gif

ImageMagick does the magic and we have our gif :) !

convert -layers Optimize out.gif out_opt.gif

Reduces the filesize a little and optimizes the gif.

To reduce file size adjust parameters when creating the gif. I got pretty good results with a setup like this

mkdir frames
ffmpeg -i vid.mp4 -vf scale=320:-1:flags=lanczos,fps=5 frames/ffout%03d.png
convert -delay 6 +dither -depth 8 -colors 128 -loop 0 frames/ffout*.png out.gif
convert -layers Optimize out.gif out_opt.gif
