Hey Ray/John/Barry, (I'll email too)

Turns out it is invite only. (Which Ray already guessed)

Brett is a bit (well a LOT) annoyed I mentioned it at all, 'on the internet'

He also said that Rich is there only to answer Q&A's, and has nothing to do with the projection side of it.

My reply was to say that, well I'm kind of proud that they are using our place to do do the demo. (But at the same time, like I keep saying video projection in cinemas scares the hell out of me)

There will be like about 700 industry people there, so I going to butt out, and leave it to those people.
I originally thought (assumed) it would be a few hundred and just a rock up if you want thing, clearly I've got it totally wrong yet again.

Ray, Brett thought you would have been invited anyway, he's not sure. Did you get anything?

This means my question list for the Q&A is dead.

Yet a again I make a fool of myself on the forum.

Bill.

Hi Bill

Thanks for letting me know.

Michael, I guess they just wanted to make sure they put it in a cinema NOT using Filmguard so the comparison (Bill, they ARE doing a comparison, right?) would look more extreme...or maybe they've just heard about Brett's legendary film handling techniques. [Wink]

I can't remember what the nights schedule is, but I'm sure it was to compare scenes of a 'certain' movie
projected in digital video to the same scenes projected in 35mm.
I'll try to get more info, but as as said before, I just prefer to butt out now.

Regarding us not using filmguard, don't know if the demo ppl would let us, even if we were (using it),
perhaps like you said they don't (prefer) want to make the film look too good. (Unlike others we AT least use PTR's)

But, wouldn't this be a good time to go ok...
Here's the Film Demo, Video Demo, NOW watch the FilmGuard Demo. Which looked BEST ??!!!!
(Better make sure the lens and port are clean, and the Xebex cranked up nice and high, 160amps)

But now I'm wondering about the sound. In previous video projection, we just hook up the sound to
the A/V input of the Panastereo. Clearly this would not involve any kind of 'digital' format sound.
The DA-20 and DTS-6D are out of the loop in that case, Just Matrix 4 Channel analogue?

As for film handling techniques, I know your tongue'n'cheek there, but hey, it's GM who makes us
move prints from screen to screen to screen and with all those stairs... God I hate that,
When an usher and I are moving 10 of 'em on a Sunday night for a Monday Day,
I can tell you some of them are not handled too well!! [Smile]

In general film handling we use all ideas presented here, with one major exception, in that we
use PTR's not FilmGuard. But it's my job to change that, and Brett wants it done.

Have you or anybody ever had feedback from Atlab, film companies or disibiutors about them getting
their film back coated with FilmGuard? (Think I might have already asked this one - because I thought
H**** had an issue with FG when it turned out to be someone hitting the film with WD-40)

(I'll edit this when I wake to myself)

Bill.

I did not know that my film handling was that well known to all and sundry. how are you John? long time no see [Roll Eyes]

I have taken note of all that has been said in this forum and will do my best to get some feedback on the day in question but I might be just a little busy what with all those film movements and all those stairs that Bill was talking about.

All joking aside it will be interesting to see the comparison. I am not concerned at all about digital projection as it will not happen at the Orpheum , they will never replace the Century's jeee they just bought two new ones only 2 years ago.
I think we could get at least another 50 years out of them before we can seriously think about digital stuff, Im just getting the hang of this DTS SRD stuff.

I should make smaller replies then i might get to be Jedi Filmhandler one day.

Hi Brett!

Nice to have you aboard Film-Tech. At some point, go ahead and download the video called, 'Interlocking 101', because I've always wanted to interlock all 6 screens at the Orpheum, and I think we can find a way to achieve this.

Also, imagine playing a film in one theatre but taking up on the platter in the cinema of your choice. You'd never have to move a film ever again! Simply take up on the platter in the theatre where the film plays next, and you're done. [Smile]

Seriously, I guess I won't be able to make it on Sunday by the sounds of things, but by all means please post your findings here. We need a full, detailed breakdown of the event with pictures if possible. [Big Grin]

Bill, don't worry about getting another digital format through your Panastereo's, there are more 6 track inputs than you can poke your (walking) stick at. And I will be at the demo on Sunday (thanks Brett) provided I can get my sea kayak out of beautiful Sydney Harbour in time to get there by 9am.

Michael haven't they now got some Panalogic CA2000 automations in the newer cinemas at the Orpheum? Just replace the (shonky [Wink]

)Pennywise stuff in the older cinemas and all 6 cinemas CAN be interlocked (with some tricky roller arrangements) exactly as you suggest. (You of all people should know that!)

See you Sunday guys.

Ray

Well it turned out to be more of a demo of High Definition video and HD cameras than of digital cinema. The projector was a Barco RH with a 2k xenon. None the less very interesting morning and an impressive image for a relatively small projector. The audience were mainly TV, Film and Video production people. The image source was an HD SDI tape.

The best D-Cinema demo I have seen so far was the screening of Treasure Planet at CineAsia in December. On that occasion I think the projector was Chrisie DLP and the picture quality was superb. But what impressed me most was the (non-Dolby Digital) PCM audio. Very nice sounding and lacked all the harshness of Dolby Digital.

There is one thing though that really bothers me about digital projection which I noticed in Bangkok and also today and that is a noise that looks like heat flowing across the screen which is very visible on large areas of a single colour. Also I have noticed a subtle flickering effect at times in one or more parts of the image.

Even though I have had hands on experience with the Barco Industries DLP Digital Projector, I still prefer the standard 35mm Projectors for now. Yeah, the picture quality and sound quality is excellent and there is no film involved, but, let's just say for instance that there is a problem of some sort and the movie had to be stopped. Well, actually, the movie would have to be paused right where it's at; otherwise, if the operator stops the movie, then, it would go right back to the beginning of the movie. That is the only downside right now.

IMHO, with 1280 x 1024 pixels, just don't sit too close to the screen, or the "jaggies" and pixel structure are visible. Many high-end computer monitors do better than that.

But John, blow the standard 15, 17 or 19" monitor up onto a screen of many feet and see what happens. I can see the jaggies in the font on my screen in the "Preview Post" button and I am only 3 feet away.

Blowing anything up creates jaggies. I think we all agree that with higher densities coming on existing (D-ILA), and future chipsets (DLP?), the jaggies will be reduced, not eliminated, to where they be much less noticeable.

That was my point! IMHO, 1280 x 1024 pixels were just a start:

Here's what Glenn Kennel, Kodak Digital Cinema Program Manager, had to say:

quote:
QUESTION: There has been a lot of discussion about how much resolution is 'good enough' for theatrical projection. What should be the standard?

KENNEL: We are starting with 2K because we believe you need at least that resolution to create natural looking images that don't block up or have jagged edges. We also believe that in the long term we can do better than 2K. That's important, but resolution accounts for just part of the 'film-look' that audiences associate with a movie-going experience. Today's color negative films give the creative community the ability to record subtle nuances in contrast, colors and textures that are important components of their visual language. We are committed to doing whatever it takes to develop a system that retains all of that visual information. We are determined to set high standards for digital cinema, and we intend to make on-going advances in this technology that will enhance the cinema experience.
