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, so there are 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.
