[Build-A-Bump]

The idea

I was making custom bumps in After Effects and despite how simple the format is, it was more friction than it should have been. Build-A-Bump is a browser tool that makes it as easy as it should be: black background, white text, a piece of music, done.

It was also a chance to build something with the Audius API that isn’t just another streaming client. Most Audius integrations are players or feeds. This is a creative tool that happens to pull music from Audius, which felt like a more interesting use case.

How it works

The format is deliberately constrained to match the Adult Swim bump format. Black background, white text, images, and up to 15 seconds of audio from any Audius track. No video footage, no complex compositing.

You add segments to a timeline, control when text and images appear, pick a track, choose an aspect ratio (16:9, 1:1, 9:16, or 3:4), and render an MP4 in the browser. Projects save to local storage automatically, and you can export .bump files to back things up or move them between devices.

The whole point is going from idea to export with as little friction as possible.
