This page doesn't explain what FFglitch does, or how it's different to ffmpeg. For instance, what's Glitch? I'm guessing it's an architecture, but the post doesn't explain what it is or contextualize the term "architecture."

The clearly labeled "What?" button at the top of the page explains everything.

The what button doesn't explain much.
As far as I know, "glitching" is opening a jpeg file with a text editor then deleting random ranges of characters, saving it again and then letting image viewers try to open the file, resulting in artifacts being added to the image.
This project seems to do the same for video files, but generating a valid video at the end.

From what i understand "glitch art" is using compression artifacts and encoding errors as art.
Presumably ffglitch is ffmpeg with code to fudge the file checksums so that encoding errors are allowed to accumulate instead of triggering an error.

Not a lot of info on the page about the process, etc, but this is also called "datamoshing." If you're curious, there's a great talk from Demuxed '21 on some of the details: https://www.youtube.com/watch?v=Qtia43DGSrY

Glitch art, not glitch arch. The main page https://ffglitch.org/ is a slightly better introduction to the project.

You know, i was all ready to be dismissive of this, using encoder errors for art sounds silly.
But i watched the video and it really was cool and artistic.

Awesome! I remember seeing Datamosh 2 plugin for After Effects, but didn't know it used this open source project. Turns out there is a whole bunch of GUIs for ffglitch: https://ffglitch.org/frontends/
