QuickClip

QuickClip keeps a rolling buffer of your screen in memory and saves it as a clip when you press a hotkey, so you don’t need to record everything all the time.

Capture runs through a native C++ engine, so recording costs very little: frames come from DXGI Desktop Duplication or Windows Graphics Capture and are encoded on the GPU. Audio is captured per application, so game, voice chat, music and microphone land on separate tracks you can balance later.

Clips go into per-game folders, and the built-in editor (powered by libmpv) handles trimming, cropping, per-track volume and stitching clips into montages.
