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!

Good thing they fixed it in Always The Same Color.

To have true VHS effect, I think we should train AI for this, examples from digital videos to record on true VHS tape, on multiples VHS devices then digitalize and calculate difference between original and digitalized from VHS.

Then even we could have filter like: VHS Panasonic, VHS Sony...

This would be very interesting project.

Great, now I won't be able to trust that old videos aren't AI slop either.

I hope this leads to people being interested in more and larger public gatherings. Seeing things with our own eyes and having fun with other real people.

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 surp…

I've never been a smartphone user, and have moved from a Flip Camcorder, to various point-and-shoots in video mode (never liked very much), and just in the last 3 years, have discovered that Sony handicams are now pocket-sized, I never considered carrying around one before, but it's actually completely reasonable.

The model (HDRCX405) is wonderful, 30x optical zoom a real value-add over smartphones, but also I just love the ergonomics in general, very easy to pick it up, and start a video within a second.

That said, Sony discontinued the low-end handicam line last year (this model went from $200 new to $800 used), which is really unfortunately, right as I hope this niche might gain momentum.

In 2009, I recorded a video of the after effects of a torrential downpour in Toronto on a Sony HDV camera. I also called up a few news stations to see if I could sell it.

I ended up reaching CFTO (CTV Toronto), and took the footage over to Channel 9 Court. What happened next took me by complete surprise.

The flagship station of a national network had no deck in the building that would play HDV mini DV tapes. I hadn’t brought my camcorder or my MBP either, so I couldn't quickly convert it into a format that they could use.

I ended up going home, and exporting via FCP and burning onto a DVD. It worked, I got to see the inside of a news station and I got $135 for it. The news broadcast later that day showed about 10 seconds of my footage, which by extrapolation, was the highest-ever hourly rate I’ve ever earned: ~$48,600/hour.

The lesson here was that DV and DV-adjacent workflows were difficult in a pro context even when they were mainstream in the consumer market.

In my decades working in TV it was always "Never The Same Color."

I was immediately reminded of the fake VHS line artifacts for Stranger Things - A Bad Lip Reading[0], which I assume are sort of a bit about the fake film grain things during the opening titles in the Stranger Things show.

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.

This one does. You can configure the noise injected into the signal and when it gets too much, it loses sync and the picture starts rolling. It's actually a software NTSC modulator/demodulator, not just an effect to simulate it. https://github.com/LMP88959/NTSC-CRT

I sincerely appreciate this fidelity to fidelity

This will be the thing that does it. That sounds reasonable.
