Vactrol based CV input to mix the two video signals. So you can use a LFO or another envelope to control the mix. (inspired from this project)
Added video signal attenuators for both inputs. (You can get more glitch effect before the crt monitor gets a black/blue screen if you turn one of the attenuators a bit down.)
Added a push button to each video signal to turn it 100% on even if its attenuator or on/off switch is turned down.

If you don't know what a dirty video mixer is, just search for it on YouTube. There are many videos showing what glitchy and distorted video signals you can create with it. I love to use it together with two RecurBoys as video inputs, an envelope generated from an audio signal (with an envelope follower module) to control the mix/distortion and some old CRT monitors as output.

Build

Order the PCBs from the PCB manufacturer of your choice.
Order the components from your favorite electronics supplier. I used this momentary-push-buttons , these vactrols and this RCA-Jacks but you can also find them somewhere else ;)
Solder the components to the PCB and mount the panel.

Description

implementation of Karl Klomp's Dirty Video Mixer in 6HP, but with a few modifications: Vactrol based CV input to mix the two video signals. So you can use a LFO or another envelope to control the mix. (inspired from this project) Added video signal attenuators for both inputs. (You can get more glitch effect before the crt monitor gets a black/blue screen if you turn one of the attenuators a bit down.) Added a push button to each video signal to turn it 100% on even if its attenuator or on/off switch is turned down.
