Hey, I want to set my own delays to a composite video signal, for use of live video feedback effects (for visuals / art purposes). I am no electrician, but this can't be hard to do right? After searching a few hours online, I haven't come up with any device that I can buy which will do this. Is there any such device / how can I make my own "delay signal" device? All I would want control of is having 1 knob for example control the delay timings of a signal in milleseconds, with 1 composite video in and 1 composite video out of course. Can anyone guide me in the right direction?
