gif-from-tweet

There are so many great GIFs out there and I want to have copies of them. Twitter makes that harder than it should be by converting them to MP4 and not providing access to the source material. To make it easier, I made a bash pipeline that takes a tweet URL and a filename, extracts the MP4 from that tweet and uses ffmpeg to convert back to GIF.

Dependencies

• ffmpeg
  • macOS: brew install ffmpeg
  • Ubuntu/Debian: apt install ffmpeg

// @ts-check

// I run this in a folder using `caddy file-server` with the two files below
// and an index.html that's more or less just including this file as a script,
// `<script src="/audio.js"></script>`

// prerequisite: two files representing a transition that should be gapless. I
// used the first two tracks off Meshuggah's "Catch Thirtythree" because I
// happen to know that album is intended to be gapless.
