If you want to turn your movies into GIFs for efficient viewing, I made/vibeslopped a little script: https://github.com/combatwombat/movie2gif
GitHub - combatwombat/movie2gif: Bash script / ffmpeg wrapper that converts long videos, like full movies, into GIFs.

@combatwombat very cool! It might make a nice addition to http://ffmpeg.app/ too.
FFmpeg.app

A website where you can search for and perform video and audio conversions, right on your browser.

@danielquinn Oh nice, browser based even. It supports only one command though, but movie2gif runs ffmpeg twice, with some temporary storage needed (extracting frames → creating GIF from them). But maybe it can be made into one step somehow.
