Resolution        Define the resolution of a captured video. The video frames can be scaled to any size in rendering, but choosing a larger resolution improves rendering quality with some cost in performance.                clSize         
Frame Rate        Define the framerate of video capturing, in frames per second                Int32         
Runtime Status
XAML Video Viewport        Returns a live XAML control that renders the captured video. The control can be used for data binding to the Content property of the XAML ContentControl element, e.g. . The ContentControl can be added to the status screen or to the GUI Layout element.                UIElem..

Webcam Element is capable of capturing output of computer video devices, e.g. web-cameras, at the background of a running experiment. The captured video can be then rendered on the stimulus or status screen, using a custom XAML control. On the majority of modern computers a work of the element should not cause an impact on timing accuracy in an experiment, however, you should check timing accuracy on your setup, when the Webcam element is used.
