Hi:
Some video websites say that spatial aliasing causes jaggies, other say
it causes the Moire effect, still others say it causes pixelation. Who
is right? What does spatial aliasing look like?
Also, which video specs are measured in "Hz" -- regardless of whether
the video is analog or digital? I believe "frame rate" is one of them.
In digital video, what specs are measured in Hz?
What specs are measured in Hz in analog video?
Thanks,
Radium |

Radium,
Why do you persist in these ventures?
It would be difficult for one to research the subject as you did and not
answer their own question.
I removed Xposts

Well, I still haven't found the answers. |

I would like to know the artifact[s] spatial-aliasing causes. Does it
cause jaggies, Moire, or pixelation? Or all 3? |
