I tried search subjects only for "nois*", and searched subjects and text for "how to tell if a souce is noisy". The first search returned only results about noise filters, the second returned too many results. Searching google for "examples of video compression noise" returned no useful results that I could see.

What I am looking for is an example, hopefully in pictures, of a noisy image resulting from compression. I.E. let's say I want to apply some light noise filtering in CCE to make a DVD9toDVD5 reencode look better. How would I know what kind of source to do this to, without knowing what noise looks like?

Watch an old vhs tape. U see the roughness in the picture? Nowhere close to the clean look of a dvd. This is noise in the signal.

I wish I could be more descriptive.
