In my somewhat engineering based background, I'd always opt for the better solution, especially if at the end of the line, the costs for the better solution probably are about the same. The extra costs for the anamorphic lenses are most likely easily recouped in other savings.

Also, in my humble opinion, you should try to optimize the way the light flows trough your projector as much as possible. If you end up throwing away a huge amount of light and resolution for a large part of your presentations, I'd consider this design as deficient.

How does it come anamorphics are now considered virtually transparent devices? How could an anamorphic, considering all aspects of their use (up until automatic movers) be the optimum way for light through a projector? I want to see the anamorphic than can cope with 4k and +4000:1 contrast...

Light efficiency is only ONE aspect of that equation. And it only has that benefit for scope presentations. Then you will need to supply all scope features in square and non-square DCPs to cinemas with and without anamorphics. Both for 2D and 3D. Now how may studios will get on that train?
And some multiplexes may have screens with and without them and need to assign the right version and playlist to corresponding screens.

Sounds like another Technicolor 3D to me. I do not even know why I'm writing in this thread. It's nothing but silly to think this would ever happen.

Again, non-square pixels are not needed. Also a dual inventory of real scope and fake scope DCPs would be unnecessary either. That is unless a d-cinema server is less advanced than a fucking DVD player made in 1998 that could make an anamorphic DVD work on a square TV set.

Very few movies are released in any "flat" format (1.66:1, 1.77:1, I.85:1) these days. The prevailing majority are all in 'scope. You can go back and look at my math figures. Even if all DCPs were anamorphically squeezed, including flat ratio movies, those flat ratio movies wouldn't lose all that much. A 1.85:1 movie squeezed for a 1.25x anamorphic lens would still have more native pixels of detail than the letterboxed fake scope movies being distributed on DCPs today.

I don't know why you're so dismissive of the idea. I've laid out plenty of specifics showing 'scope treated in the manner I'm suggesting would be a big improvement over the sad bullshit being passed off as 'scope today. Current DCP 'scope is no better than watching it at home on Blu-ray. It's letterboxed, TV set style 'scope.

I guess you only consider the anamorphic add-ons. I don't see a reason why a truly anamorphic lens, which is designed that way from the ground up, would be considerably less transparent than a spherical lens.

Most studios already deliver plenty of versions of many of their movies already. 2D, 3D, 5.1, 7.1, Atmos, Auro and a few permutations of that.

Sounds somewhat familiar, doesn't it? [Wink]

In all honesty, I don't think this single inventory thing will ever fly... It never really was and never really will. In the history of exhibition, there has almost never been a true "single inventory" system.

I guess it's part of the business. Exhibition done right isn't easy, it still takes a lot of work, knowledge and showmanship. If it was as easy as playing a DVD or a movie on YouTube, most of us would be out of business rather soon.

Don't you disqualify yourself a bit with those kind of statements? Aren't forums like this one the place to discuss something like this?

You might be right in stating that the fact that this will, most likely, not happen. Still, why can't we have a discussion about the possible benefits and downsides of an alternate approach without ridiculing it?

I'd still go for non-square pixels in the source. Why is everybody so afraid of them? Even the Lisa had them, although we know where that went. [Wink]

If you go for optimal quality, you don't want to have your cinema server or any other thing digitally stretching or "deforming" your content. No matter if you use linear, bilinear, Lanczos, bicubic or outer-space filtering, you will lose detail and you should know that.

Really Carsten? No pun intended but you are sharper than that! The anamorphics available are made by ISCO, the best anamorphic company in the business (ever). They aren't junk. I have them on 4K projectors and have zero problem resolving 4K pixels (apparently a better job than some IMB/IMS systems). I can't claim to have tested how they affect contrast ratio but DCinema is not nor will EVER need to exceed a real 1000:1 (simultaneous black and white projected...the sequential BS numbers). Beyond 1000:1, no fire marshall will approve of the theatre's ambient light level...it would exceed even the Motion Picture Academy which, let me tell you, gets VERY black in the theatre when the lights go down.

The other reality is if there is a renewed interest in the use of Anamorphics as a cheap means of improving the movie going experience, just like with film anamorphics, development and competition on digital anamorphics would emerge. That is just the nature of business. As a low volume item, they are going to be expensive.

The fact (as a matter of physics) remains, getting light through round holes is more efficient than getting it through rectangular holes. With the wider ratios, if the imager were to go to a 2.39:1 ratio, then we still would need to fit the round cone of light through that rectangular imager (the return of "beam spreaders...anamorphics on the lamphouse side of things) and even then the constant width theatres would then have to zoom the lens to get Flat to fill the height and waste light on the side walls...or use an anamorphic in the other orientation.

There would NOT need to be dual inventory, ever. I can't speak to Sony but every DLP based projector has the ability to set an anamorphic factor that would either compress or expand the image vertically. It would merely become like it was for DVDs...old movies would do scope by letterboxing within 4x3 and new movies would do it by encoding it anamorphically. You add another preset to the projector. If you don't have the anamorphic lens, the anamorphic factor would be .75, if you do have the lens it would be 1.0. If it is done the "old" way, it would be 1.25. You don't even need to change the screen masking settings since how you fill the imager would be the same for any form of scope.

As for the industry doing it...it is a matter of the first person with clout saying they are going to do it and if it is a success it may stick and become the new way it is done. We are in times where the studios are clearly experimenting. This summer we have F-220 and F-200 releases almost on top of each other and NO theatre was really set up for that (except my retro houses where dealing with "70mm" releases necessitated having 2.20 formats at the ready).

What percentage of the theatres showed these 2.20 and soon 2:1 releases without the image looking properly "zoomed?"

Sorry for the off-topic, but do we already know that Jurassic World is F-200, i.e. 1998x998 or thereabouts?

Instead of being S-200 (1716x858) or C-200 (2048x1024), that is...

Steve, we know anamorphics have been done and will be done whenever there is a business model for it - and that is increased light output or better balanced light output. But some here actually think that there is a 'picture quality' business model based on the combination of anamorphics with non-square pixel 2k DCPs and increased vertical resolution over the classic 2048*858 spherical way of doing scope.

That's no business-model now that the world has spent their money on the digital rollout, that's a nerd-model.

Antti,

Yes, at least in the USA, we know since the spec sheet is now on the Deluxe site. I like how they say it is in the Flat 1998x1080 format but in the title it says F-20:

"JurassicWorld_FTR-4-2D_F-20_EN-XX-CCAP_US-13-INT-TD_71-HI-VI-DBOX_2K_UP_20150526_DLA_IOP_VF"

The 5.1 version is the same but with "51" in the audio section. The 3D versions follow suit too.

I dunno Carsten. I think there IS a business model for Super 2K and Super 4K. In the scheme of things, it is VERY cheap to use an anamorphic stretch to increase resolution for Scope as compared to other forms of VERY expensive "quality" improvements. The fact you get more light just makes it all that more attractive. If there is a business model for immersive audio, then there is a business model for anamorphic encoding on the image. Both technologies will be lost on the masses and both technologies will improve the final result.

We need technologies that differentiate us from the home experience and anamorphics would improve our picture yet cost the theatre that doesn't want to fool with them zero except to have another format on their projector (that can support what? 64 formats at minimum?). If you can remote in, you don't even need to go to the site to add in the format.

Carsten, obviously you're calling me out in passive-aggressive manner.

I never said anything ever about using non-square pixels on a DCP. No current hardware in use is compatible with non-square pixels. Non-square pixels died with old 4:3 TV sets. My ideas about Super 2K and Super 4K involve using normal square pixels. The square pixel imagery on the DCP is simply made in a different manner during post production. They render a 2K 'scope image in 2560 X 1080 and digitally re-sample it to fit 2048 X 1080. 4K is 5120 X 2160 scaled to fit 4096 X 2160.

You're throwing this business model crap around in an attempt to support a claim there wouldn't be any quality difference between 2048 X 858 fake scope and 2048 X 1080 Super 2K sourced from a 2560 X 1080 image. A full 2048 X 1080 frame has 2211840 pixels. A fake scope frame has only 1757184 pixels. That's a difference of 454656 pixels just for 2K. That's a damned huge difference. Scaled to 4K the difference is quadrupled.

Have I missed something? A reply to Brad's question about a thousand posts ago: is anybody showing this feature in Scope with just a slight trim off the picture height?
Also, would converting to anamorphic or to 4K be the better option?

I don't know anyone showing it in scope. If you did, it wouldn't quite fill the screen in width while cropping a bit in height. I have one theatre, for sure, that is running it in 2.20:1.

The theaters I've installed are running it in scope, but then again my targets are always dead on without having to blank pixels. Even though I'm losing a few pixels on the top and bottom, it's less than a typical theater would crop on a normal 1.85 or 2.40 target and it looks FAR better than that "just run it in flat" nonsense.

Yes there are small pillarbox bars on the side, but that's always preferable to the evil letterbox.

The best option would be anamoprhic Super 4K:
5120 X 2160 digital intermediate master,
re-sample 5K 'scope image to full frame 4096 X 2160,
unsqueeze during projection.

A 2.20:1 would be slightly pillar-boxed in that kind of work flow, but the pillars are easily hidden by movie theaters using common height screens and movable masking. The 2.20:1 image would carry quite a bit more native resolution than the letter-boxing nonsense currently taking place within a flat container.

Bobby,anamoprhic Super 4K would be desirable but I am asking what would be the best option given existing choices.
Brad, I have not run the feature yet but I projected the Tomorrowland trailers with flat and Scope settings and the letterboxed flat image looks, as you say, crap. The pillarboxed image was more acceptable. Unless the feature has extremely tight scenes with essential action in that top six inches, this would probably be the way to go.
We might have a 2.2 setting before our season but, failing that I will try a Q.C. screening in Scope.

That's not true actually. Every current D-Cinema system with an anamorphic lens or attachment would be perfectly suitable to play back a DCP with "squeezed" and thus non-square pixels in the DCP. If you play it as a full container and switch to your anamorphic lens, you're already there. It works for both 2K and 4K.

On the other hand, asking a cinema server or projector to squeeze 5120 X 2160 back to 4096 X 2160 is something that needs upgrades to either the projector or the media block.
