RT Extreme expanded effects preview and allowed an external monitor through FireWire or a breakout box. The package included LiveType for titles, Soundtrack for music, Compressor for transcoding and previously separate Cinema Tools for film work.

The consulted Apple specifications explicitly cover 4.0.1: a 350 MHz G4 with AGP graphics, 384 MB RAM, DVD drive, Mac OS X 10.2.5 or later and QuickTime 6.1 or later.
