OK, after studying a few episodes of Most Haunted last night, I felt confident enough to hold a séance to contact DeathieMouse from "The Twilight Zone". Please excuse any spelling mistakes, you won't believe how long and laborious it is to write down his wisdom when you have to note down every single letter one at a time as the glass moves to it on the Ouija Board. And its not as if he moved that glass quickly. Oh no. On Most Haunted it goes flying over the board. Not with our Deathie. It was like a snail was pushing the thing. Not to mention the pesky interference from unwanted spirits! You're halfway through a transcription and then a book goes flying across the room, thrown by an evil spirit from your bookcase. It is rather off-putting and can ruin your train of thought.
The things I do for Ultimate Disney. Anyway, without further ado, here's what DeathieMouse said about my post on NTSC colours, and the new DVD transfer in general.
OK DVDs are encoded in some form of Yuv
RGB is separated into b/w (Y) and colour differences (uv) and the color is quartered (made 1/4th the size/resolution) (so a image that's 3GB becomes 1.5 with the b/w being 1 (untouched) and the colour being 0.5 (quartered)
NTSC has trouble with colours because:
Originally: 1 NTSC is the NTSC phosphorus gamma 2.2, black = 0 IRE
but phosphors on tvs weren't those!, gamma on a CRT s actually 2.25, and NTSC color set up is actually black = 7.5 ire
then, you have auto color and auto tint
AND! the reason for having a tint control was technically this: EVEN if you had everything above perfect, NTSC signals traveling though the airwaves and connectors over long distances changed chroma phase (tint)
PAL fixed that by using the "Phase Alternalte Line" system
Then on top, on NTSC the Yuv signal is further compressed into Yc
and the c is piggybacked onto the Y signal
so a TV has to separate those with a notch or comb filter
on broadcast and Laserdisc is that way (called composite). o VHS and S-VHS the signal is actually recorded as separate Y and c but if you dont get prerecorded tapes or your VCR dont have a S-video cable (actually a Y c cable) the YC merge piggyback is done on the way to your tv
(cus TV used to only accept NTSC composite remember?)
and all that was analog so it had frequency losses and noise
DVD is much better cus its Yuv COMPONENT DIGITAL
the only NTSC and PAL remaining is the 576 and 480 size. and interface
not even the aspect ratio is the same as i explained many times, 1.33 vs 1.37
so this is correct: "I believe DVD does not have these colour problems because they have a digital source, not encoded to NTSC on the disc"
this is correct but not exactly clear why,: "and digital cabling from player to monitor/TV".
its not the cabling per se, its that the signals are encoded separate (and of course the cabling keeps them separate in Yuv (the red green blue cablesc alled "component"
its just not RG
er RGB
its Y (b/w) u (red difference) v (blue difference)
(the green cable crries the Y)
now as to why colors are different
Cinderella was shot though a red 25 Green 58 and Blue 47 filters (or similar) (the RGB gel filters in some test discs )
into b/w film
thats a color record
then those b/w records were dyed with a set of yellow magenta and cyan dies that was manipulated to get the color you wanted (like playing with Photoshop colors! (a chemical photoshop!)
that was THE TECHNICOLOR IB PRINT AND THATS THE TRUE COLOR REFERENCE
the old videos were maybe made from Eastmancolor prints which look totally diferent
the new DVDs were made by scanning the b/w negatives into video RGB.
and referenced to the cels. not to the technicolor prints
so right there color is f**ked
a reflective cel can only have a contrast ratio of 100:1
(remember the maximum 2.5 dLog i mentioned the other day?
a technicolor print has a contrast ratio of 5000:1 or more
so the contrast brilliance and saturation can be 50 times better than the cel
2nd problem
only a $6000 not designed for motion/gaming NEC LCD has colors approaching NTSC Technicolor. sRGB/HDTV/PAL/SMPTE "C" monitors have half the color
(SMPTE "C" is the phosphour set that after 40 years of NTSC wildness manufacturers agrree to use for $$$$$$$ profesional broadcast monitors. its like 95% of PAL (EBU) phosphours
sRGB/HDTV red and blue = PAL
sRGB/HDTV green is the average of the PAL and SMPTe green
(something like PAL green x = 0.28 y = 0.60 SMPT green = x = 0.32 y = 60
then sRGB/HDTV chose x = 0.30 y = 0.60
"The lines on characters appear to be thinner as well,"
thats good. that means its higher resolution
"such as the whites of the stepmother's eyes often being blue and how whites were quite dulled and gray" thats two reasons: the new transfer has acryall highlight detail instead of being blown out ("duller whites) a white cloth on a DVD should be at around 86% RGB (if black is 0% and pure white is 100%
the blue highlights is cus Lowry is still using Lucas uncalibrated monitor!
all lowry transferes are too blue or yellow!
I hope that makes sense to somebody, or else it wasn't just a whole night of mine wasted, but I've also infested by flat with evil spirits for nothing.
Disclaimer: Kids, don't mess around with Ouija Boards. It may just be nonsense, but its better to be safe than sorry. I suggest you use instant messaging instead.
The PE DVD I have contains the old Walt Disney Pictures logo (except the restoration end credits) as well as the 1995 VHS release had the Buena Vista logo on it, both of them had blocked the RKO logo. Great find, the mystery was solved!
Good job Netty!
