ffmpeg + gifsicle + giflossy + ImageMagick = GIFs From Videos in Linux
simple setup and a readymade script for converting MP4s (or WEBMs) to animated GIFs, form Ubuntu 16.04 or Fedora 25:
I started making some .gifs to embed in documentation and my notes as I develop Rusty Nail. I always have to lookup how to convert the images to gifs. Everytime I am also concerned with how big the .gifs are so after doing some looking around I made a little script which uses ffmpeg, convert, and gifsicle (with giflossy) to take an input mp4, webm, or any video that ffmpeg can decode.
The process is this:
ffmpeg splits the video into a directory of gifs
convert those images and stitches them together into one gif.
gifsicle optimizes the gif and allow a stage to resize it and also change the color. The giflossy plug-in also can apply lossy compression to the gif video during the optimization step.
