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…

One of my favourite quotes too.

> "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…

Yes, they loved the compactness and convenience (well, I’m not sure anyone ever loved the rewinding/fastfowarding experience) But the quality/color was always a noticeable downgrade from broadcast quality video (and that was a noticeable downgrade from film). But the sacrifice was absolutely worth it. It is notable that LaserDisc only came out two years after VHS (and before it reached mass adoption), and it could pr…

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…

I wouldn't call it a voice break, more an intentional melodic variation by singing a perfect fourth higher than the expected note in falsetto. But I agree: it sounds marvelous.

I don’t it’s the imperfections that are being chased. Most people don’t pay attention to technical details like that. Instead it’s about chasing the era. For example, the 80s/90s seemed like a happier time, for both those who grew up in it and those who don’t, and imperfections like VHS artifacts put the viewer in that mindset.

Nostalgia plays a part for sure.

For those born after an era it can be easy to romanticize an era. And for those who lived through it, it can be easy to remember the good, and forget the bad.

Growing up in the 80s with no cell phones meant it was much harder to co-ordinate schedules, events, social events etc. No "I'm outside, where are you?"

Ultimately each era is different. Some good, some bad. But in 20 years expect your kids to be idolizing the "20s". "Such a simpler time than now..."

"You got to stay home for a year? What fun...."

I had written a NTSC emulator in C, based on some other equations I had found, although it expects command-line arguments to control many things (such as the phase), and expects a grey scale farbfeld picture as input and produces farbfeld as output, so it is with still pictures rather than videos.

I disagree with this, the lack of cellphones meant that once people agreed to a plan, they stuck to the plan. "Meet next Saturday at 17:00 at the main square", and everybody would be there.

Nowadays people keep arguing and changing plans until the very last minute, it's exhausting.

Could this be used for training AI to do the reverse, i.e., generate high-quality videos from older analog TV and VHS artifacts? Start from high quality videos, use this or a similar library to generate analog/VHS videos that now have the ground truth available, train AI from the data.

I'm gonna have to "yes, but" here. Yes, there's no doubt the limitations of a media are interpreted by most as desirable things to chase, like scanlines in a crt that's outputting a low resolution image.

But there are also certain qualities in analog audio or video that were lost or severely degraded in the technologies that came after. For example, you need an extremely high bitrate mp3 to get to the fidelity of a vinyl (CDs can achieve it without issues, though) and in crts image clarity in movement is still unmatched in modern displays, and will probably always be due to the sample and hold nature of modern displays.
