Feedback
They say if you can remember the Sixties, you weren't there. In those days, we pointed a camera at a monitor which was showing the same camera. The result was Amy Stewart's "Knock on Wood" video clip. Everything old is new again, and video feedback is back in. But those party-pooper engineers at Thomson want to spoil all our fun - for no good reason - and prevent us doing it.
Some of us have a short video cable going from a Kalypso Output back into an Input. This allows us to creatively loop vision back into itself - in the Eighties they called it "Recursive Effects" and charged extra for it. But that's a hardware solution, and it may not be possible at your place. Here's a way to do it without 30 cents worth of cable and two BNC connectors.
- Create your effect (talent Chromakeyed over Black) on M/E1A.
- Key a Transform Engine under your Chromakey, and offset it a bit. (Zooming in and rotation will look good, too.)
- Put Still Store 8 into the key row feeding the TE (any SS will do).
- Select M/E1A to the input of the Still Store.
- In the "Still Store | Create/Edit" menu, delegate SS8 and press [Show Input].
- M/E1A is now entered recursively. Feedback!
Move the TE around and see all the groovy way-out effects you can create. Instead of a Chromakey, you could have a soft-edge modulated rotating wipe, and you've made an instant animated background.
There are more uses for this particular Recursive Effect in the Effects section.
