Veejay is a visual instrument and real-time video
sampler. It allows you 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 be used to
manipulate video in a realtime environment such as
visual performances or for (automated) interactive
video installations.
