You say it is art so precise reproduction of the original physical scene may not be the goal.
If the intent is to preserve the trashed signal aspects that a TBC would try fix or would cause a capture card to drop frames or otherwise hic-cup, but a generic TV set would coast through displaying what it may (because most TV sets were forgiving of sloppy signals) recording off screen might be the better bet. Use a TV with good color reproduction, and camcorder with variable shutter (e.g., clear scan) to avoid the scrolling retrace bars that results from the camcorder and display having slightly different speeds.

The community generally refers to the effects produced from circuit bent analog video devices as "glitch." I know, it's not a true glitch if you're forcing it - but that's what they call it.
You are totally correct about recording off screen. Most people in the community use rescanning, and there are loads of guides on shutter speeds, moiré fixes, etc. I'm just hoping for a capture solution, because I hope to pipe the captured video directly into other streams.

THIS is EXACTLY what I'm looking for!
Thank you so much!
Also, holy heck those things are expensive! Time to start saving I guess lol.
Do you know of any other similar devices? Do you think other, perhaps cheaper ED gear might work?
Thank you again!!

Nearly all capture cards will output nothing if the signal is too bad to varying degrees, so not sure how easy it would be to find one that doesn't.

Yep - I've actually got a couple mixers from lucky auctions. A large part of my current effects is a quad feedback loop between two mixers, with one of the weak chromakeys tuned to the other's feedback, then the other's chromakey tuned to the first chromakey. It's wild!
Anyway... you're totally right too that these help cut down on blue screens. (
I also built this small sync restoring circuit recently too.) But, I'm not so worried about the capture card not functioning - as I am about it not capturing a
faithful reproduction. It seems like most try to "correct" the image in different ways - and I'm trying to purposefully modify those signals.

Thank you again to everyone who replied - I definitely have a decent starting point with the Bright Eyes 75.
If anyone else knows of any capture devices that
create 100% faithful reproductions of what they're fed, please let me know!
