Give each action a clear focus.

The camera tracks clicks and the focus of each action, so viewers always see what you are doing. After recording, the camera framing, pointer size, and click effect are all still adjustable.

  • Automatically follows clicks and the focus of each action

  • Pointer size from 50% to 300%

  • Drag and resize the camera frame directly on the canvas
