[Jukebox-list] DLP-was-Movie Sound

[Ron Rich]

John,
  Now you got me--What is a "DLP chip", and how does it configure the movie so that a single bulb can "project" it ??

A digital projector works like a regular film projector it projects
from the booth has a 3000 to 7000 watt bulb. The movie is stored on
a hard drive and is processed through a DLP chip and out to the screen.
all the jitter and shake and dirt and scratches that you now see
are all gone. The Studios will save all the film costs and will
help fund the change over. I have found a lot of that title
movement is in the way the tittles are printed.

John, how will a "digital projector" work? Does it still actually
project, or will the screen be like a giant plasma tv? I assume there's
going to be some improvement in the picture? I notice that most movies
today still have a bit of jitter or slight shaking up and down (very
noticeable on stationary titles). What will replace the "film"?

Well,

Now the movie industry is going to digital projectors, 35mm film
equipment will be for sale every where in the next year. So it wont be
but a few years and we all can say we remember when they used film.
The sound will be digital to a converter which will make it analog so
the processor can send it to the amps and speakers.

Although production of films in Vitaphone pretty well ceased by 1930,
many films were distributed in the format into the late 30s because
cash-strapped small-town theater owners didn't want to shell out for the
sound-on-film equipment. Films were a nightmare to make in Vitaphone
because you couldn't have scene changes in mid-reel unless you blocked
the action like a live television show or stage play. Background music
and effects also had to be played in live like a radio play.
Towards the end, Warner Bros. had a method for mixing sound from
different sources that involved a lot of turntables, stop watches and
timing systems that raised and dropped tone arms based on the number of
revs of certain turntables.
Besides being a logistical nightmare to operate, the loss of several
generations in the process produced a final product that had noticably
degraded sound quality.
