Some that bubble up from the memory bank-
“Video Feedback” – point a camera at a monitor with that camera on screen, move, zoom around slowly.
Use the feedback video from the camera into a switcher to mix with other sources, or as a key signal.
Doing a slight mix with the feedback video to achieve a “recursive” look, smear, trails etc.
Vidicon, plumbicon cameras with lots of knobs on them allowed the video engineer to “beam starve,” which “soft clipped” highlights and often provided a streak or trail.
High contrast keys – used an external source- another camera, motion footage, artwork, whatever- as an “alpha” and inserted camera video or generated background colors.
Not sure that AE or other software solutions can easily duplicate the recussive smear, feedback or trail effects that were achieved with a switcher and hardware DVE, often done on the fly. Maybe there’s a school or cable studio that has some old gear you can get your hands on to play on and see what you come up with..
