Far too often people associate edge enhancement with greater resolution and detail. I think that is happening here.

The real test of sharpness is to look at the fine detail in a long shot --- can you clearly see the faces in the crowd scene? ---can you see the individual leaves rustling on the trees? That's what separates 2K, 4K, 35mm, and 65/70mm. If there are only 2048 pixels across a 60-foot screen, each pixel is still about 0.35 inches wide.

If there is anything that makes an image look like "video" i.e., "electronic" and unnatural, it's freakin edge enhancement. [puke] If it's not there to begin with, good chances are that you are not going to be able to create it artificially. If the resolution wasn't captured to begin with nothing you can do is going to be able to "create" it after the fact.

To be sure there were subtle differences from film, but when you can see "film grain" from the originating film, you are most of the way "there."

Exactly Louis! The grain was not obvious but definately there if you looked for it... very fine stock was obviously used. I will reiterate again... it looked so close to high quality film dailies that it was almost scary and its obvious to me now why most shows are now projecting dailies with D-Cinema equipment. Since I used to do alot of video system alignments of true high end video gear I'm quite familiar with edge enhancement and its effects and how it looks. There was no visible edge enhacement in anything they ran at Dolby that I watched.

We were told that the most difficult thing to render digitally was rain. The system at Dolby did that flawlessly.

I for one am not going to keep my head burried in the sand regarding D-Cinema. When the conditions are right and circumstances call for it I will happily be installing them.

Hey Mark, we FINALLY agree on something!

It's just ashamed that it isn't time yet.

When I watched dailies (admittedly, I'm going back 15 years) they were on small screens. 35mm and 16mm looked brilliant.

The release prints were superb too. The producers supervised the process and the labs were fastidious.

Our screen is not monsterous, so most films still look great. Although I wish they all looked as beautiful as The New World.

As far as Dolby taking time to get it right, when are they going to improve the durability of their digital sound track so that we don't have to switch to analog on prints more than 6 weeks old (from other cinemas)?

Most of what we see in theaters these days has already been run through a digital intermediate at 2K resolution. And it sucks. As John P. pointed out, you can't see good detail in wide shots or crowd scenes. It's less noticable in closeups, but that's not all there is to movies. Those few movies with 4K digital intermediates look much smoother and more detailed. That's the goal digital cinema should be heading towards. 2K isn't enough.

And then there is the issue of contrast. Aside from the occasional movie printed on Kodak Vision Premiere, which looks great, most movies these days are printed on cheaper stocks, which leaves us looking at milky blacks. Yet every single d-cinema presentation I have seen has been even worse. You want to see really muddy, milky looking dark scenes? Just go look at one of these Dolby D-cinema installations. Yuk.

And BTW, it was Richard Cook, now a big mucky-muck at Disney, back then around the time TOY STORY first came out who said he would be perfectly comfortable with "releasing all Disney films in digital because it's good enough right now" said he; and he was talking about 1.3K!!....you know, the system that is already obsolete. THIS kind of mentality is what we are up against, my friends. And it SHOULD scare us....rightfully so because we may very well be dooming future generations to visual mediocity....quality that is much lower than what we have been privileged to experience ourselves. And THAT prospect is like a knife in my heart to know that my descendants may never get to see LAWRENCE OF ARABIA, MY FAIR LADY, 2001, et al, the way I saw them. There is something evil about today's power brokers who don't care that this many come to pass, and it means nothing to deprive future generations of the best that our truly indiginous art-form can give.
Well said, although Cook's statements were actually more around the time of Toy Story 2, or just a little bit later. But yes, he did indeed say that 1.3K systems were already "good enough", which is ludicrous.

That is absolutely not Dolby's fault, nor is it the fault of the labs or the makers of the film stock. That is directly the fault of bad projectionists and a lack of proper film lubrication. Using Toy Story 2 as an example, I put over 1500 passes on that print I ran and it was still tracking perfectly. (I don't recall the error compensation rating, but it was 2 or under.)

If I actually thought there was a market for true projection training, I would open up advanced training seminars 4 times a year for those who already know the basics, but need to learn how to perfect their presentations.

When I say Laurence of Arabia in 70mm it was the re-release with exta footage in the 90's. I saw it at the Hoyts Centre Cinema in Sydney.

When the film started the picture was even but a little dim. Within 5 minutes the CW3 (lets not call them a projectionist) ajusted the Xenon. Well it was really bright in the very middle and pitch black on the edges, It was a horrible experience and I often wondered what happened when the action moved away from the centre of frame.

Now that was over 10 years ago now and to be honest the situation of poor staffing has only got worse. So when people say that 1.3K dig was good enough, well they may have a point. With the major chains haveing made their beds with there constant budget cuts and zero quality control, I am often amazed that people bother to come at all.

Unfortunatly the professionalism found on this site is now rare in the industry, but its good to know that the mom and pop operations and selected larger operations still have a dedicated, trained staff and will not have to waste there money on early examples of digital cinema simply because they can still milk 35mm superior image. Unfortunatly the big boys really need to do something.

Brad do you really think that dolbys decision to put the sound between the sprockets as ideal? Thankfully some genius invented film gaurd which to me seems like the ideal companion for long term quality Dolby Digital presentation. As far as I know, as yet no big companies use this product here.

you won't know until you try it. brad, i really think you should be doing this.

you could get the ball rolling with a discount for f-t members.

Cameron, yes between the sprockets was absolutely the smartest place to put the digital data. Can anyone say SDDS? That being said, that same print of Toy Story 2 I referenced above also played fine and dandy the last week in SDDS.

Carl, the problem is that to do the training properly, I would need to set up a training center with a wide variety of equipment. Training centers without this are only really training on the theory, and not the specifics of each model of machine. Short of that, it would take a bunch of local theaters to permit in-house training which would end up forcing the cancellation of shows. As you can imagine, getting through all of the obstacles of setting up such seminars would be an issue. Plus then there is the issue of students. I don't think large groups would be proper training either, maybe half a dozen maximum.

Reality Check..... Unlike the ballpark in the cornfield... you could build it but no one would come! You could train at your facility until your pants catch on fire but it wouldn't do a bit of good since you'd be talking to the wall at the other end of your classroom. Do you actually think any employer is going to pay big money to send a $4.00 per hour employee to your facility? The only way for this to ever work is for you to train a bunch of very competant people of your own and send them out to individual theater sites like the old Kodak training program. The only way to really get things straightened out is to get the theater owners... large and small... to first pay their projectionists at least a half way decent wage so thay are not being replaced by another no-nothing every three or four weeks when they are offered another 3 bucks an hour at the local McDonalds.

What I see is huge turn around in the booths and the lack of any film handling related mechanical aptitude test that should be required of any booth personel applying for the job. That and the huge turn around I see are the largest cause of no one knowing anything about proper film handling in the booth let alone having anyone that could recognize a mis-aimed giudance roller, mal-functioning pay out, low oil, or a loose screw.

If you want to do something good to start off with come up with a standard test for film handler prospects that cold be downloaded from this site to filter out those that don't even have the ability to hold a screw driver, recognize a loose screw in a piece of equipment, or a mis-aimed guidance roller or let alone handle a roll of cleaning media properly. There are way too many of these sorts of people attempting to run the booths out there today. Also you'd best be prepared to re-visit the sites every time there is turn over the the booth and the kiddies have run off to work at McDonalds.

Oh, and you will also need to train them for proper digital operation at the same time since it is quickly making inroads at many locations (there will soon be nearly 50 of them in SLC alone) and you will be visiting booths that are digitally equipped as well as film equipped... As John P. mentioned "Digital Done Right" is just as important as "Film Done Right"!!

Mark hit the nail on the head on that one. We used to do a training program where our technician and at one time an actual trainer came around and trained the booth staff in trouble shooting and things. Problem was that by the time the trainer got back around to that theatre the staff was totally different. So he was having to train or retrain people. Now that has been abandoned. Now he pretty much tries to find that one good person and hope that the knowledge passes down. We pay our staff above minimum but you still only get the collage kids who can't work days and are out the door when they graduate.

Then there would need to be a huge advertising campaign to raise the awareness among the giant group of "projectionists" and theatre operators that have never heard of Film-Tech.

I still think that Brad should produce rolls of stickers that say, "To learn how to improve your presentation, check out FILM-TECH.COM" which could be distributed to all interested Film-Techers. We would all start applying these stickers to the inside of film cans, or to reel flanges, whatever.

How would going digital have prevented that situation? Digital projectors have Xenons, too.

I'm constantly surprised when people propose digital as a solution to problems that could just as easily happen with either digital or film projectors, such as poor/uneven lighting, focus, etc. Going digital would not help in those cases, yet people talk as though it would. It just doesn't make sense, and goes right back to Brad's original question: What is everyone thinking?

Image and lamp focus are actually less an issue with digital systems as the only focus problem would be one caused by lens focus. There are no focus problems as can be caused by bad tracking of film in the gate, failed cooling, uneven gate bands, etc. The Christie CP2000 have a lamp autofocus function which actually works very nicely to keep the lamp mostly in focus and the current on a constant light level. I don't know if other 2k models out there have that, too, but I wouldn't be too surprised if they do.

RE What is everyone thinking, that could be said right back here. It is obvious that a lot of people are having opinions about the whole digital cinema thing without really much or any practical experience and knowledge of the subject.
It *is* a very interesting subject and also very interesting to compare it to 35mm, but as someone who has worked with digital cinema more than most other people here I have to say it is very, very tiring to read all those posts from people who don't really know what they are talking about and just spam the thread with all their uninformed nonsense.
