Press the key after it happens.

Clip Recorder runs in the background with no overlay and no capture button. It keeps the last two minutes of your screen and sound on a rolling buffer, and one hotkey writes that buffer to an MP4.

You never have to decide to record. You only have to decide to keep.

The buffer, running

Press it, or use the real keys — this page listens too.

What it does to your machine

Nothing is drawn over your game: No overlay, no watermark, no capture indicator composited into the frame. The only thing you see is a tray icon.
The GPU does the encoding: Frames come off the desktop through DXGI Desktop Duplication and go straight into NVENC, up to 240 frames per second.
Windows never learns it is there: No installer service, no registry keys, no administrator rights. Settings sit in a config.json next to the executable.
