  … there was a discussion about how video cameras sampled an image (4:2:2 etc) and someone posted a link to a very informative video explanation; it was part of a regular webcast series and made by (what looked like) the AV dept of a university. I’ve tried searching the Cow and have come up dry.

  Thanks

  [Dave LaRonde] “In this particular episode, Pixel Corps founder Alex Lindsay describes AND demonstrates the color resolution differences between 4-4-4, 4-2-2 and 4-1-1.”

  And let’s not forget the ever present 4:2:0, which MPEG-2 and (by extension) HDV use.

  I always like to go to Wikipedia for more information on a subject (hey, I haven’t been burned yet):

  Thanks, MacBreak was the one. I had found the Studio1 stuff but it was the video I wanted.
