Recording

Automatic zooms

While you record, Lumen tracks your cursor and clicks, then glides the frame in on the action and back out again. You don’t set keyframes.

Tracking samples cursor position at 60 Hz and listens for mouse-button downs. Positions are normalized to the bounds of the captured display. The clock starts when the recorder starts.

Note

Windows get the same tracking as screens on macOS, Windows and Linux (Xorg). On Windows, Lumen records the area the window covered when you started, so keep it in place while recording. On Wayland, neither screens nor windows get cursor tracking.

Camera bubble

Add your webcam as a rounded bubble in the corner so people see who’s talking without losing the screen. Turn it on when you pick what to record.

What gets baked into the export

Exports include the zooms, the Lumen cursor overlay, and the camera bubble. On clean captures the system pointer is kept out of the frames so only the overlay is drawn.
