WHy do you think DVD is suited of archiving?
Do you know how bad the image qualitty is compared to a film original negative?
Would you ever want to take your photo negatives,scan them and put them
on a computer disk in form of small 720 pixel wide compressed files?

If you want to capture all the image data from a motion picture negative negative
you have to scann it at at least 4500dpi resolution which would give you
files of some 4000x3000 pixels (anamorphic format) and they would have to be uncompressed
unless you want fake skin tones in your prints.
That given,on a single DVD medium you could store maybe 30 frames or so.
This is a bit more than a second of film.

And besides film is still the best way to archive something,you never have to vory
about file conversion,new equipment etc.

The best way you can archive color negative film images is to make color separations.
Print the negative to 3 separate black and white films using color filters to
extract basic RGB chanels.
This is what most hollywood studios do these days. I'd say that about 90% of films
have these color separations made for archiving.
the sicret is in the fact that black and white film doesn't fade like color film.
And those separation film stocks are made from a polyester base that does not
decompose that fast.

A film printed on black and white color separations can last up to
500 years if stored at recomended temperatures of about 7 degree celsious
and 25% humidity.

Lucas made color separations of Star Wars in 70's but they were made on
old film stocks that had acetate base (can deteriorate and shrink).
Shrinking is a nightmare for such aplication,you have 3 roles
of the same scenes,and if the films don't match you get color problems.
New polyester films do not shring like that.
If Lucas made new color separations today the films would be preserved
for 100's of years.


By the way. It is not celluite or whatever.
It celluloid .
And you make it sound as if celluloid film base has anything to do with fading.
No. Old emulsions from the 70's have fading problems.
SW was shot on an very early version of eastman 5247. If Lucas waited
just for one or two years he would have minimum fading problems because
a newer version was introduced then (Alien,Empire strikes back,Blade runner)
which did not fade that fast.

And by the way.What do you mean that is all he had??
This was the best choice. No other imaging format could give such
qualitty. Not even today. THere is nothing today that can match film qualitty
in motion picture world. Episode 2 was shot on HD video,and that is why
it ended up looking like crap cinematographically. The resolution was
good enough for film prints,but if you could get a hold of a direct
answer print of any of the films from the old trilogy (or a 70mm print)
you would see that the qualitty is much better than that of episode2.


First off, be careful who you attribute quotes to. It was the idiot who started this thread who made the cellulite error.
As for scanning @ 4500dpi, consider that most release prints only retain, @ best, resolution easily captured by a 2K scan. This is why most people cannot tell the difference between HD and film. Scnning @ 4500dpi is overkill and may, in fact expose certain elements (matte lines, wires) that were meant to be obscured by the reduction in resolution of a release print.
SW:ANH's biggest problem with film stock was that 5247 was a CRI (color reversal internegative) stock, which is extremely prone to fading. Not all the film was shot in 5247; it was only the effects shots that were handled this way, because it reduced the number of generations required in optical printing. As for shrinkage of the seps, Warner is using a new process (dubbed Ultra Resolution) that scans all the seps in, converts them to their appropriate colours, and uses computer technology to digitally correct shrinkage and prevent the fringing that results when shrunken seps are recombined. The first DVD released in this process was Singin' in the Rain:SE, and it has since been used for The Adventures of Robin Hood and will also be used for the upcoming release of Gone With the Wind. I don't see why LFL couldn't licence this to produce an all new answer print of ANH.
Finally, while 70mm is bigger, bigeer doesn't necessarily equal better. The 70mm prints were blow-ups and as such, bring a lot more grain into the image. The best way to see the OT is still in 35mm. Episode 2 may have looked less than stellar on the big screen, but it looked pretty amazing on DVD. That's because a digital-to-film conversion inevitably saps some of the colour and brightness from the image. If you'd seen AOTC in a DLP venue, you would have been blown away by the image.

I can see it now -

* Lucas limps into a press conference with a black eye, broken arm, broken leg, teeth missing, multiple scars, cuts, bruses and announces "After being "enlightened" by a most persistent Star Wars fan, I will release the O OT on DVD " *

LOL!


OK, I officially LOVE this idea.
