| 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.

| 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. <ContentControl Content='{Binding VideoOutput}'/>. The ContentControl can be added to the status screen or to the GUI Layout element.

'''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.<br><br>
