.gifs to embed in documentation and my notes as I

The process is this:
ffmpegsplits the video into a directory of

gifand allow a stage to resize it and also change the color. The
giflossyplug-in also can apply lossy compression to the gif video during the optimization step.
Read on for the script.
To use my
make_gif.sh script you will need the following applications:
These should be installable from Ubuntu 16.04 or Fedora 25.
$ make_gif.sh -o my_new_image.gif input_file.mp4
You can get help information with:
$ make_gif.sh -h
gifs are a pretty useful format for adding video content to
documentation. I realize that the
.webm format might be a better alternative,
in the long run. With less effort, you can get higher compression rates and
smaller file sizes, all with better quality and the option for integrating
