Maybe she meant "block noise"?
Newbie question! ^_^; What *is* the difference between 'block noise' and pixelation made by the compression? And what do you mean, 'the codec doesn't cause pixelation' - are you just saying that it's the amount of compression done *using* that codec that causes it, or that the pixelation comes from something else? [Doesn't a lossy codec cause more pixelation than a lossless one? I'm confused as to how the codec is *not* to blame here.]

Yes, curious (and confused). ^_^;; Are you talking semantics or something about compression and the resulting pixelation/noise that is foreign to me?

www.megapixel.net wrote:Pixelization

The step-like appearance of a curved or angled line in digital imaging. The smaller the pixels, and the greater their number, the less apparent the "pixelization" of the image. Also known as the "jaggies."
I think the point he was trying to make is that you dont know what pixelation is, because video compression doesn't cause it :?


Pixelization would only be caused by downsizing the image then upsizing it again.

I just dont get what he's saying.

Pixelization:

Macroblocking:

My codecs do the latter. If yours do the former, I suggest glasses :|

Correction, RV9 doesn't macroblock or leave mosquito noise. It just leaves roxorallothercodecssuck artifacts.
My bad.
