Also, remember that all less-than-full-bandwidth video schemes are engineered
to take advantage of the design of our eye-brain system. Humans are much better
equipped to percieve luminance and detail information than colors. Formats like
like u-matic, vhs, hi-8, beta, et. al., all strive to record wide luminance
bandwidth and fill between the outlines with fuzzy color. Still images might
look awful, but in motion everything looks right. CCIR-601 (D-1,YUV,4-2-2)
gives you the highest quality possible balanced against the limitations of
NTSC, which itself is designed to economize bandwidth based on our eye-brain
specs. 24-bit RGB (4-4-4) or RGBA (4-4-4-4) is only useful in the production
processes of rendering, painting, compositing, etc. . None of that extra data
can get through the transmitter or be displayed at home on a TV . . . YET.
