ManyCam is a freeware program that allows users to have the ability to use their webcam with multiple chat applications simultaneously, such as Skype, Omegle, Chatroulette, MSN, or YouTube. Users can also add live CGI graphics inside any webcam application, such as changing the appearance of their face, eyes, hair, background and more. ManyCam Pro is a paid upgrade, it provides users with a professional quality live video production studio.
There is also a simple module for creating effects included on the website, which mainly consists of adding image files, videos, and converts them to a ManyCam friendly format. Face effects and backgrounds can also be created. The ManyCam website has a database of more than 9,500 webcam video effects, most of which were contributed by users.
ManyCam uses a webcam or video camera as input for the software itself and then replicates itself as an alternative source of input. Because of this, ManyCam works well with nearly all chat software such as Windows Live Messenger that can use alternative video sources.
