OpenLogomotion

I kept seeing those fast-cutting logo videos — the ones where a logo snaps through a dozen backgrounds on the beat — and I genuinely love how they turn out. But every online tool that makes them does the same thing: you build the whole video, it looks great in the preview, and then a decent export sits behind a subscription. There's never a free option that gives you a quality file.

I was deep in exam prep and wanted a small side project to keep my hands busy, so I rebuilt the format myself and gave it away. OpenLogomotion is the result.

What it is

You upload a logo, arrange a few background frames, point it at some audio, and it exports a vertical match-cut video. The logo stays fixed in the center; the frames cut behind it on the beat; the whole thing loops to fill the export. Frames can be solid colors, palette bands, or your own images, and you can end the video on a held "end card" for a call to action.

Everything runs locally. Your audio is analyzed in the browser and embedded in the export — nothing is uploaded, there's no account, and there's no watermark.

How I think about it

• Free where it matters. The paywall on these tools is always the export. So the export is the thing I made sure was free and unrestricted.
• Preview is the export. The live preview and the rendered MP4 run the same Remotion composition, driven by the same data. What you see is exactly what you download — no surprises at render time.
• Local by default. Onset detection and rendering happen on your machine. The only network call is a one-time headless-Chromium download the first time you export.

The two articles below are about building it: why I rebuilt a paid format as a free local tool, and how the cuts actually land on the beat — including the part where I had to throw out my first beat detector because it didn't work.
