It's impossible to have a pristine signal when talking about film and tv. Having to transmit over wires and having to go from analog to digital will introduce quantization noise. Additionally raw capture and playback isn't an option because of transmission bandwidth limitations. And displays aren't in 12bit color depth, the most obvious visual example of poor quantization is color banding. While less obvious, film grain does the same for increasing the perceived texture. The quantization errors observable in video are different than in audio and I was trying to make an analogy that feels intuitive. I think the street picture in this link is helpful. https://www.hdnumerique.com/dossiers/962-test-4k-ultra-hd-blu-ray-schindler.html https://www.hdnumerique.com/dossiers/962-test-4k-ultra-hd-bl...
