On: Vintage digicams are an artistic statement

Good questions. CD distortion include hard clipping from amplifying too much, whereas vacuum tubes and magnetic tape have soft saturation (still a distortion, just a different kind). Another distortion is that dynamic range compression is used, bringing up the volume of quiet parts of a song.

As for digital video jitter, I can think of MPEG compression artifacts, both spatial (e.g. DCT mosquito noise) and temporal (e.g. motion compensation errors, periodic keyframe refreshes).

That is bad mastering, not an inherent property of CDs.

It's not, but it's very, very common, basically the rule in fact, starting I think in the early 2000s.
