pretty cool!

I do love that this is an area of such active development. But I'm curious to see what the artifact simulation crowd thinks of it. I most often encounter them as shaders for emulators and such, but of course this kind of structure degradation of a pristine video is also in high demand these days for video production. Producers want that 90s-camcorder look but crews can't actually use the clunky 90s-camcorder hardware and formats.

I'm actually surprised there isn't much of a scene for authentic camcorder footage - directors love to bust out real black and white film cameras for stuff?

Film is a fun, interesting, authentic, and useful medium for filmmakers, and there are established workflows for it. A camcorder writing interlaced video to miniDV may have its charms (I still have a great old Panasonic 3CCD one) but as a filmmaking tool it would be really inconvenient. Shooting in an ordinary digital workflow and adding the effect later is a no brainer production-wise.

That said, I would not be surprised to see camcorders, DV or VHS or whatever, rise up as a Polaroid-like alternative to smartphone cameras! Old digital point and shoots are already popular that way.

You're not getting the full experience of analogue telly artifacts until you emulate colour subcarrier phase shift and colour burst detection failure. (-:

And of course PAL and Hanover bars.

Which is why NTSC was often said to mean Never Twice the Same Color!

I once tried to fully analyze the amazing NTSC emulation used in OpenEmulator. I went down a rabbit hole that involved losing motivation several lessons in to a signal processing class on YouTube, but for those interested, I did at least pull quite a lot of it apart here: https://observablehq.com/@zellyn/apple-ii-ntsc-emulation-ope...

I also ported it to JavaScript (linked from above page)

It looks quite unusual, I will definitely try it.

Greg! I love this!!! Just last night I was trying to rewatch the x-files and was telling Luna that I would need to get a TV filter/shader/overlay thingy to see it the way it was meant to be seen.

You mind reader you

You need the 80s soundtrack for the full effect: https://www.youtube.com/watch?v=8oVfIFrpslI

Idle thought: I don't think I've ever seen one of these TV emulator things implement the situation where the vertical oscillator was slightly wrong and you get the picture slowly looping up the screen.
