VeeJay – realtime video sequencer and effects processor

Veejay is a visual instrument and realtime video sampler. It allows users to “play” the video like you would play a piano. While playing, you can record the resulting video directly to disk (video sampling).

Veejay can be operated live by using the keyboard (which is completely user definable) or remotely over TCP/IP.

Veejay can also be used to manipulate video in a realtime environment such as visual performances or for (automated) interactive video installations.
