I'm familiar with the quote. Still don't like this nostalgia-esque recreation. As someone that spent many hours in edit bays dealing with these tape based artifacts, seeing them now is not nostalgic but brings out a Pavlovian response nearly PTSD like triggering. However, I do understand why others less in the trenches of trying to avoid these types of issues would want it.

I'm getting really tired of seeing dust and scratches applied to YouTube video. Especially when it's applied to zooms and pans over stills.

Absolutely this. Blind application of a technique, not understood by the one applying it, is jarring. IMHO it insults the era from which they were trying to mooch cool points.

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…

So in future we will have "retro" streaming platforms that buffer with the spinner a random times for nostalgia and have menus full of promotional material that are impossible to navigate to just find what you're looking for.

if these things ever went away? we would absolutely have nostalgic recreations.

now, i am not so optimistic we will get there, however.

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.

The trick is that the scratches need to recur at the right revolution rate, while the bandwidth needs to slowly decrease as the stylus nears the end of the groove. Hmm.

CD distortion? Did you mean vinyl record distortion?

We all want what we don't have. Back in the day we were desperate for a clearer picture and found these artifacts annoying. We longed for an alternate reality that was as crisp as our own. Nowadays folks that didn't experience the pre-digital era want aesthetics that embrace the imperfections that today's visual culture glosses over. They want reminders that life wasn't always this way.

Speak for yourself.

> CD distortion What?

Advent of digital mixing and therefore the loudness wars started roughly contemporaneously with the compact disc audio format becoming mainstream. Most complaints of AAD mixes of old vinyls converted to disc were poor, and DDD mastered stuff sounded harsh because of the novelty of compression (audio compressor, not filesize or redbook/Wav/CD-A compression.)

Maybe. I lived through the 90s as a cd purchaser and I tend to agree, CDs were real nice, but different. By the time I had a cd player, tapes had exotic coatings and EQ-trickery to mask the hiss and whatnot of tape media.

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

Finally decided to see why "raster" and it was the Germans, from latin for "rake" ; and it meant scanning-field.

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.

I actually posted ntsc-rs as it came up in my research - I'm also looking for something like what you're describing..! I was also looking into https://codeberg.org/fsphil/hacktv which generates a variety of different analog tv signals (meant to be broadcast using HackRF) - but yes, I want the opposite - an analog-receiver-emulator...? And one that would be "ok" with incorrect signals // fail like an analog TV would..…

Slow scan and fast scan television encoders and decoders exist, probably the algorithm is public domain, so you can just increase the bandwidth and speed until you get what you're looking for, then you can tamper with IQ .wav files to edit the "signal".

It can't be that hard for someone with skill and determination!

Probably quantization noise is meant:
