To shoot and edit and create, digital is great, but as an end consumer
product, I have to say, I'm disappointed.
lately, as I wander through all the best Buy and Circuit City and Sears
stores and look at the 42" Plasma or LCD or DLP monitors, each pre-viewing
the latest hollywood blockbuster, I begin to cringe as I take a close look
at the images on these screens.
Compression artifacts, giant square pixels that dance around, strobe-like
shimmering static backgrounds, all makes me long for the days of analog.
Lets do the math...one hour of video at 720 X 480 in SD resolution is nearly
70 GB. DV does that 5.2:1 compression and shrinks it down to about 13.2 GB.
This is still good quality, but it wont fit on a DVD.
So we compress it down further to 4 GB as MPEG-2 DVD, resulting in a 17.5:1
compression of the original.
This results in those annoying artifacts enhanced by large screens.
granted, no one watches these screens 8" away, and when viewed from 10 feet,
it's hardly noticable, but the fact remains, they are there.
I suppose when holographic DVD's become mainsteam, each with a capacity of
100 GB, that will reduce the compression used, resulting in a cleaner
picture....NOT! Sorry, what was I thinking, that the industry will do
this....just like idiot after idiot abandoned their C-Band satellite dish to
go digital (better picture with digital, duh...) and my cable company now
offers "superior digital signal" (yeah right, with video on demand and
remote record now, play back later options, saturday night is artifact city
on my screen, thanks to overloaded bandwidth), people have this false belief
that digital is the way to go...any time there is fast motion on a digital
cable channel, it goes all pixellated and blurry.
You people are pro's, what do you make of all this overused digital hype?
