BoinxTV is an application geared toward podcast production. It lets you combine the video signal coming from three different cameras and apply all sorts of special effects in real time. The resulting clip can be saved in a file or can be played live on a different screen.
It includes five templates that simplify the task of creating a project, and a system of layers that lets you overlap different graphic elements with the main image: marquees, clocks, logos, signs, credits, etc. Plus, you can add transitions when changing the video source.
BoinxTV supports chroma-key or alpha channel, which lets you make audiovisual presentations where the original background image is substituted by a different one stored on your computer. This is the same effect you see when you watch the weather forecast on TV.
