Blockade: Video acquired by low fidelity devices like cellular phones and PDAs is becoming more commonplace. Blockade makes your clip look like it is highly compressed and being transmitted through a very bandwidth-limited pipe. Essential for simulating internet based micro cam display or personal video communication.
Artifact: Developed to create digital defects, Artifact simulates lost DCT blocks and frame dropping, most often seen when a digital video file suffers from corruption or a satellite feed is hampered by weather. Make sure you warn clients and your house engineer that it's only an effect...
Interference: If it's television you want, traditionally you'll need some sort of interlaced field scanning. Interference creates the look of interlaced video fields, even on progressive footage or still images, adding noise, colorization and offset separately for each field.
Skew: The never-ending quest to aim the rabbit ears so that the television show looks as good once you're in your chair as it did when your hands were attached to the antenna is fast fading into the lore of old... That valuable (if under-appreciated) look is preserved in Skew. Uniquely analog/broadcast image badness like noise, image shearing, ghosts... it's all there.
