OVERALL SUBJECTIVE CAVEAT-
I base this on OTA reception with a SIR T-165 into a HD LEEZA into a NEC 10 PG CRT.
RE: WKBW IMAGE QUALITY --
I think we all acknowledge that WKBW is still testing and will give them the benefit of the doubt -- for a WHILE -- in the spirit of promoting HD.
That said, it is also as good idea to acknowledge and keep in mind that WKBW has been dragging it's feet for years on HD . . . . and when you are last you are invaribly and appropriately compared to whoever was first . . .
AND, I think it is appropriate to hold WKBW to a high standard.
RE: CROSSING JORDAN
Yes, Friday night's broadcast was VERY dark -- I had to raise both the black and the white level to get what I would call a "normal" image AND boost the chroma.
Last Sunday's show was MUCH better quality -- at least picture-wise.
Unfortunately, with this boosting the up-converted SD commercials were WAY too hot.
Which leads me to believe that some thing is a miss at the network if the network is doing the upconverting on national commercials which I assume they are.
Long story short -- VIDEO LEVELS seem to be ALL OVER THE PLACE in HD
I assume these are the annoying growing pains of a new format and of integrating HD programs with up-converted SD commercials . . . .
AND, what a shocker, it would appear that the commercials are taking first priority
RE: quality control. I have NEVER seen a national TV spot on an HD feed that has had the kind of video level problems that the HD programs ROUTINELY have.
Again, I would assume that this is in part due to HD's greater resolution and latitude
AND most likely, just that the HD signal is different from the NTSC signal .. . .
AND because 99.9% of the bill-paying commercials are run from NTSC masters
it would seem the technical deck is slanted toward NTSC and not HD.
So, what does this all mean...
It will all get better as the HD growing pains get worked out.
However, in the short run it is helpful to let the broadcasters know when they are doing
badly and when they are doing well. Complaints and compliments will speed the process along.
I finally sorta confirmed this level issue with the waveform and vectorscope monitors
in Final Cut Pro.
The commercials scope pretty "normal" and the HD programs are all over the place.
NAVY NCIS = blacks severly crushed which increases the chroma level -- in NTSC. The hue/tint was swung toward the magenta.
On Friday 3/12/04
JOAN of ARCADIA = black levels high ie milky and white level low = milky
.....immediately followed by...
JAG = blacks somewhat crushed, chroma level very high.
.... immediately followed by . .
CROSSING JORDAN = black level a bit high, white level very low, chroma level low.
These are all taken RELATIVE to the commercials which ALL looked and scoped
Granted, these are software based monitors being fed an analog down-converted HD signal that is then digitized and re-digitized a BUNCH of times before it is displayed
so this is far, FAR from being any kind of a standardized test.
What it DOES show is that the program levels RELATIVE TO THE COMMERCIALS
are, in fact, all over the place.
If I can do this on a laptop one wonders for what reason the networks and locals
aren't doing the same thing . . . . and then doing something ABOUT it.
The results are NOT subtle or difficult to interpret.
