MediaLooks Video Mixer is a DirectShow filter for real-time mixing of multiple video streams originating from different video sources – such as digital video cameras, webcams, TV tuner cards or video capture boards. (For audio mixing please see our Audio Mixer DirectShow filter).

MediaLooks Video Mixer is compatible with high-definition video and supports HDV camcorders as input sources.

If you are not working with DirectShow, we recommend that you use our Video Mixer Object - a DirectShow-independent development component compatible with almost any development environment such as C#, Visual Basic or Delphi.
