The visual effects module supports calculations and expressions for tracking, stabilizing, and rotoscoping. The keying/editing module features an Ultra keyer optimized for bluescreen and greenscreen shots, a Difference keyer that takes two images as inputs and generates a matte based on the difference between the two shots, and several additional tools. I/O batch capture video and SCSI tape I/O are available with the input/output module, and 3D depth tools (including depth of field) and distributed network rendering are available with the 3D tools and rendering modules respectively.
