Hmm, you need to see, side by side, obvious difference comparison.
Technical measurements: still useful, however. Note the 6 bars at the top, these are MHz markers. If colors under bar4, it means the frequency is 4MHz. The svideo stopped before bar4, while the C4All continued to the very edge, which is 6MHz. I'll make labels.
For the b/w pictures, it's the same thing, but showing the direct color plane (U/Cb,Pb). This is pure color info translated to b/w. It's a little easier to see.
How was it generated? Don't know, it's from a reference test disc, have faith
Smearing: not here. Example coming.
New tests coming.
My technical tests showed, 1) no freq. response difference btw svideo cables 2) svideo color response to 3.75MHz 3) C4All response off the scale, at least 6MHz.
