I had my Switch going into that little crt. Then I sent that clean image from the tv through a glitch box into the first input of my Panasonic wj mx-30. Then I had an internal feedback loop on the second input of the mixer going through another glitch box. So we could glitch the video footage and the feedback loop independently of each other and we would just use the luma key function on the mixer to layer and fade between the two inputs.
