"Bad TV" effect

January 28, 2010 | 6:31 pm

Does anyone know of a jitter shader or quicktime effect that can achieve something similar to the "Bad TV" effect in Final Cut? I’m mainly looking for something that can degrade and shake up video like on an old beat up VHS tape. Ideas appreciated!

Jitter Recipe 27: Debris comes to mind.
as well as this old patch, the origins of which i have no idea. (nesa maybe?)

but really, this sounds like the perfect project to just get crazy experimenting!

thanks Rob this old patch worked like a charm! I was able to pass a quicktime movie into is and control the parameters like so. Definitely going to do more experimenting!

Something based on this idea might work…

Thanks Andrew. Definitely adds that bad tape wobble. This along with some simulated bad tracking in the patch above will get me closer. Thinking of ways to combine some static and throw off the color synch for ultimate effect.

For static you could use [jit.xfade] to mix your video with [jit.noise]. For messing with the colour have a look at [jit.hue] or [jit.traffic].

Have not had a look at the patches yet as not at Max machine, but this is a very common question on video editing sites. I would suggest checking out some video edit sites (FCP, AE, etc) for Bad TV tutorials and translate the general process into Jitter. Have a look at a few tutes, they often offer different approaches – some will use plugins, some multiple effects and others via scripting.
Hope that helps . . .

I’ve always liked this one.

Another thing you can do is get yourself an affordable analog video converter box and actually record onto a VHS tape, pull it out and mangle the tape, and then re-digitize. Sometimes, if you have the time, actually doing the real thing is more fun and a bit less predictable.

here’s one that uses gl.mesh, taken from our CellDNA video mixing program.

Hey Peter,
The patch you posted is missing "mdlist" and "banger" abstractions.

@vade Super clever one! Love it.

Whoa lots of great ideas here thanks for the updates!

I like grabbing old tape footage as source material for sure, although a card with analog pass through is definitely a must as my miniDV cam tends to blue out when the footage gets too crazy. And Final Cut is my go to for getting this done in the editor, but I’m interested in tweaking this effect live with a patch I’m gonna be using while DJing.

I’ll be incorporating as much of this stuff as I can by Friday where I’ll be trying it all out at a gig in Brooklyn. Any new york heads stop through I’d love to demo it for you. Shameless plug below:

And an appropriately saturated video promoting the 1800 number made with the beginnings of the patch I’ll be using (bad tv effect added in post though).

For some reason, I can’t stay away from this thread. Here is where I’d probably go with it.

Andrew, I think you win this thread. Thats awesome.


February 2, 2010 | 8:38 pm

Ja, sweetness!


February 2, 2010 | 9:51 pm

Thanks! You give up too easy vade.


February 2, 2010 | 10:00 pm

Ha, I could go the shader route, I’ve been meaning to add some more fun to my analog glitch shader (s) :P I just like your approach in that one. Very nice.


February 5, 2010 | 9:12 am

A combination of the above methods is definitely getting me where I wanna be thanks again guys.

Hey Vade just curious would your shader route be more efficient? This has significantly upped the cpu usage of my patch. Still runs okay just worries me.


February 5, 2010 | 2:00 pm

some really cool patches here! nice 1 for posting.


May 17, 2011 | 7:18 pm

do you know how to move image horizontally ? can you explain ?

Andrew that patch is beautiful. :)
