Yes, more times than you i am willing to make a guess, and possibly for far longer. And also measuring bars on Waveform monitors and vector scopes and through TBC's/proc amps and any other kind of widget you care to name. And not just old standard bars either, Grass valley bars on some broadcast level system i used to use as well as many other test patterns that broke down all of the parts of this crazy old system we use. (PAL as well, although they do not have tint... bonus points if you can tell us why!)
You said in that quoted reference about the silver goop something or other
I found that after I treated the component video cables, I had to readjust the color level (lowering it by 30% from a setting of 50 to a setting of 35), and tint levels on my $30k InFocus Screenplay 777 projector as the signal strength was quite a bit stronger and the color was too saturated.
And i said that if it increased the colour, then that is something that can be measured. I also said that Tint is not a voltage thing, it is a phasing thing. SO it would not be affected by voltage.
If you would like the basics, please read this article. It was written by somebody that Joe Kane regards as an expert in videohttp://www.extron.com/technology/archive.asp?id=ntscdb1
If you read all of the linked articles, you will understand why your tint comment makes no sense.
I will give you the colour one, but i stick by my comment that if the colour needed to be turned down, you had more voltage hitting the decoder and as such, it can be measured. THis is not a phantom thing. NTSC decoding is about as well understood as anything out there. Making claims to the contrary would be silly.
I did walk out, but as with many other nitwits in this place when i see outlandish claims made by obviously uninformed people, i try to contribute to the discussion in an intelligent manner.
Now lets look at this discourse shall we... On one side we have folks talking rationally about the physical universe and how it complies with most of our laws. As such, we want to talk about how to make "stuff' perform better, so we talk about many ways (fixing electrical systems, balanced power, better grounding, acoustics, measurements, screens, and a variety of other things that may or may not be regarded as tweaks) to fix and make systems better. On the other side we have folks coming in and making outlandish claims with not one single piece of evidence that these things work other than "trust me, if you cannot see/hear the difference then you are obviously a fool"
As i have stated from the beginning, if you think it makes things better then all power to you, just do not expect products that seem to defy the laws of physics to be accepted as gospel. Many of us naysayers have seen/listened to lots of these things and found nothing there. We have seen/been party to the tests of the devices that are supposed to be so good that they will make your system seem broken without it and heard nothing. And there was always some reason why we were unable to see the difference. (am i describing the Emperors new clothes?)
As one example, if this silver stuff was so good... Wouldn't Dr. Morbius (MIT nuclear physicist at Lawrence Livermore National Labs) be using it on his test equipment? After all, he is working on pretty darn precise stuff after all. (weapons or energy or some stuff that is vital to the future) But i am pretty sure he is not, as a matter of fact, if i was able to sneak a peek at his gear, i bet i would find plain old IEC cords plugged into plain old circuits (good ground though i bet
As a matter of fact, if it was as good as you say, they could set up a test with two side by each systems and run peple through and play clips off each system and everybody would easily hear/see the difference. But guess what, almost NONE of these tweaks have EVER been verified ANYWHERE in any type of test that follows any type of verifiable controls.
So, in response i expect more nonsense, more vitriol and not much else.
