What's in a GIF (2024-02-07)

It is fairly easy to create a GIF from a QuickTime .mov file, which showcases some new product or a workflow you may have. Here is how do achieve that:

brew install ffmpeg gifsicle
ffmpeg -i input.mov output.gif
ffmpeg -i input.mov -vf "fps=10,scale=320:-1:flags=lanczos" -c:v gif intermediate.gif
gifsicle -O3 intermediate.gif -o optimized.gif

But this got me thinking, why GIF? What’s in a GIF?


Remember CompuServe? They invented GIF. GIF stands for Graphics Interchange Format and it is a bitmap image format. CompuServe led by American computer scientist Steve Wilhite and released on June 15, 1987.
