Capture everything that matters.

Camera movement that follows your flow.

Intelligent camera algorithms track clicks and points of interest automatically. After recording, every zoom level, virtual pointer style, and motion blur setting remains fully adjustable.

  • Auto Zoom follows clicks and the focus of each action

  • Virtual pointer with adjustable size and click effects

  • Drag the camera frame and refine every move after recording

  • Directional motion blur keeps camera movement natural
