Installation

1. Make sure you have jq, base64, and ffmpeg installed and on your PATH. (The script has been tested with jq 1.6, base64 8.30, and ffmpeg 4.2.4.)
2. Download the script, put it somewhere on your PATH, and make it executable.

Usage

1. Record a web page performance profile using Chrome DevTools and save it.
2. Send the profile to the script's stdin, and redirect stdout to a new file with a .gif extension (the only output format currently supported).

Enjoy!
