VCam is a virtual software camera, which simulates a webcam in your system and works just like a real one. You can use it to set images, animations, video clips, flash movies, DVD and even your desktop screen as the output of webcam. Already have a webcam? VCam can replace its background, perform face tracking, add video overlay, text overlay or cool special effects to it, and let it be able to be used by several applications at the same time.
