GRID Pro is a video performance application that gives unprecedented control to a powerful real time video mixing and effects processing environment. It features a large thumbnail interface giving you easy access to hundreds of your movies via mouse, keyboard or MIDI device. You can apply transition between movies [wipe, iris, slide, etc.] or manually control the mixer. From the mixer the video goes into the fx system where you can control the 50+ fx plugins. There is also a drag-and-drop step sequencer.
