Looking for a glossary of Video noise / error types.

[dspplug]

Hello, I'd been knee deep in video editing some years ago; and though I remember the mechanisms and best practices, my terminology has fallen short. I was looking for the other word for murra, when darker areas become... in video. If possible could someone point me out to a good guide of such terminology, I've been looking here and online; but now google is fraught with every commercial and non denoiser product and various simplistic explanations of its inner working by "experts".

Damn, looked up my old post; the word is "shimmering". *kicks himself, lol
