Fantastic! Is there something like this also for the scratch and hiss of old LP vinyl records? And the various types of squeals, crackles and fuzz of old ham radio setups? Never found anything that can really simulate those well.

I used to play with the free iZotope Vinyl VST, it does a decent job at emulating pop/hiss, wow/flutter, and frequency response.

For ham radio-like sounds, maybe use SDR software like SDR++ and just pipe in a regular audio input, then mess with the decoding settings like LSB/USB.

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

These are both amazing projects, but why does NTSC-CRT feel more accurate to how I remember television looking than ntsc-rs?

From what I’m seeing ntsc rs “just” emulates VHS and NTSC artifacts, whereas ntsc crt also does all the fun that has to do with CRT rasterizing

I never heard of this quote, but "heard" something similar a while ago, must have been 2020. I was watching a live worship session on Youtube and it was beautiful, kept my mind at peace. Now mind you at the same time I was also a perfectionist, which means you tend to see imperfections in others. Now at a certain point the singer's voice broke as she was hitting a high note. But before I could mentally register the i…

Cracks in the voice are so visceral. One I love is in the Rolling Stone's Gimme Shelter, Merry Clayton is just about screaming and her voice cracks and they kept the band's cheering reaction to it on the record [1]. Truly a case of the subject matter trying to break out of the medium. Related is that a lot of cultures embrace intentional imperfections in art for spiritual reasons, as it conveys authenticity and humil…

At about 1:30, just after the "I was very nervous" line, Haley pushes her voice until it breaks. I found it a lovely little grace note, emphasizing the lyric.

> "Whatever you now find weird, ugly, uncomfortable and nasty about a new medium will surely become its signature [...] I bet the first viewers of VHS were busier with marveling at color, compactness and convenience instead of thinking of the new medium as something ugly and nasty. New technology that gets very popular usually starts as state of the art and impressive, and it's only in retrospect that people think of…

I've always disliked VHS. Broadcast TV was available for comparison at the time and it looked much better. DVD resolution seemed fine to me at the time - it does not seem fine anymore. Cassettes were not great, not terrible compared to CDs. That is still the case because stereo audio doesn't get much better than CDs. Conclusion: Whether something seems good at the time depends on availability of something similar but…

On DVD: DVD would still look fine (I think) if you were still playing it through the same screen you did back then.

Time to wheel out one of my favorite quotes about the signature of a medium: "Whatever you now find weird, ugly, uncomfortable and nasty about a new medium will surely become its signature. CD distortion, the jitteriness of digital video, the crap sound of 8-bit - all of these will be cherished and emulated as soon as they can be avoided. It’s the sound of failure: so much modern art is the sound of things going out…

I don't miss TV movies recorded on VHD one bit, with their unstable paused picture and muddiness. Also not the slow speed and unreliability of 3.5" disks.

I sincerely appreciate this fidelity to fidelity

Fidelity to infidelity?

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…

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?

The difference is that films had better performances than digital equivalents in some areas for a long time. It isn't/wasn't just nostalgia.

The imaging device used in electronic camcorders before the transition to CCD had visibly gray whites. They weren't so great by any standards. Hence very few chases it, with nostalgia being the sole reason to do it.
