Reminds me, in revisiting Geoff’s post ^, speaking in terms of math…

This is a single step method for BT.2020 -> BT.709 (Geoff’s current TV), which one standards organization is using, as we speak:

R709 = RGBcontent(1.660490254890140 * R2020 - 0.587638564717282 * G2020 - 0.072851975229213 * B2020 )

G709 = RGBcontent(-0.124550248621850 * R2020 + 1.132898753013895 * G2020 - 0.008347895599309 * B2020 )

B709 = RGBcontent(-0.018151059958635 * R2020 - 0.100578696221493 * G2020 + 1.118729865913540 * B2020 )

I wonder if it will be a launch Ultra HD Blu-ray title, I can see that HMV already have it up for pre order, they have a steel book edition that's exclusive to them.

Let us know your impressions after your viewing. Dem dinosaurs should look big, given what’s said in the Kodak article linked on the last page.

Anticipation regarding Jurassic World certainly is getting a lot of attention on this side of the pond, for example…. http://www.nbcnews.com/nightly-news/...n-463365187834

Sorry for the random question, but do we have any information on whether or not the IMAX laser systems can pull off 4K3D, or are they still under the standard DCI limitations? I remember last year people were speculating, but I haven't heard anything recently.

Even if they could, what would they show?

I can't remember for sure which of the following statements is correct but from what I have read Imax laser projectors are two 2K projectors boot strapped together, or Imax laser projectors are two 4K projectors bootstrapped together. Either way one of them is correct it's just the resolution that changes. My point being that what ever Imax is using for laser projectors it is not an ideal solution and whatever they are, they are likely to be replaced with just the one projector when technology allows it. To answer you question it is highly likely that they are limited to the DCI spec but I don't know for sure, whatever they are Imax laser projectors defeat the purpose of Imax.

Does anyone know how time consuming and costly it is to remaster a blu-ray to 4K?

I should imagine that it takes no longer than the length of the film to scan to 4K. On top of that it will cost no more than the wage of the person who put the film into the scanner and pressed scan.

Standard IMAX digital is dual 2K projectors. IMAX lasers are dual 4K projectors, and from most audience reports, they decisively beat out film in every way short of resolution, which on most screens is a non-issue at 4K.

Most screens? This is IMAX we are talking about.

They use two overlapping projectors for a reason, it basically oversamples the image to reduce aliasing, visible pixel grids and other foibles of digital projection which would normally be all too obvious on a screen as huge as the average IMAX. Maybe a single 8K projector would alleviate that, maybe it wouldn't, but IMAX are certainly aware that they're chasing that elusive 15/70 quality. That said, image quality is lost by the time the 65mm film is duped and duped and duped again for the final release print, and there's always other stuff like dirt, wear and the slight instability of the projected image which is eating into the available quality, whereas a digital 4K master straight off of the negative will be sharper, cleaner and more stable every time.

As for 4K 3D on their laser system, I'd assume it's possible just like it is on some of Barco's higher end 4K cinema projectors (which is a single projector unit, not two in tandem). The DCI spec is a delivery system, not something which governs the overall spec of the projectors themselves, and seeing as IMAX do their own specifically formatted 1.90 shows which don't conform to the standard 2.40/1.85 ratios, I reckon they could do their own bespoke 4K 3D deliverables if they wanted to.

But, as mike rightly said, what would they show on it? It's one thing getting the filmmakers to open the mattes on their movies and another convincing the studios to shell out for for what is essentially two 4K finishes, one for each eye.

[dvdmike]

The problem with digital IMAX is they will be forced to upgrade all the time, when 4k and above masters become commonplace they will need more pixels to fill that screen.
Mind you I think less and less real IMAX's will exist in a few years.

[bailey1987]

Well I have just got back from Jurassic World, I didn't particularly enjoy it, the 3D was much improved over previous 3D experiences though. Roll on Ultra HD Blu-ray.

It won't be on it in 4k, let alone 3d I am afraid.

[Geoff D]

You never know mike, the DSM may have been in 4K but the DCPs had to be 2K because of the 3D, and mebbe Universal weren't interested in doing a standalone 4K 2D DCP.

As for worrying about higher than 4K masters that'll be true of ANY digital cinema, so it's not like it's solely IMAX's concern. And by the time that 6K/8K finishes become more common (a LONG way off seeing as we're still not there with 4K finishing & projection across the board) most cinemas will probably be going through an upgrade cycle anyway.

It's more the size of the screen it has to be blown up too that I was eluding to

[Geoff D]

Okay, but I've seen several 2K movies at the BFI IMAX projected on the dual 2K Christies and they looked absolutely fine, so with the dual 4K laser system it should smash it. They were 2.35 movies admittedly, so even if they were converted to 15/70 they'd still only fill x amount of the 1.44 screen, but IMAX know they can't do full height IMAX presentations on the current 2K setup and that's where the 4K laser system with the reverse anamorphosis comes in: they'll be able to fill the screen should they choose to do so.

The slightly ironic thing about having such a big screen is the seats are much further away from the screen than the average cinema, so even when you're dealing with 'just' 2K material there's enough of a viewing distance - combined with the overlapping projection - to ameliorate the sense of it having been blown up too much. And because digital is so much cleaner and stable than any form of film projection that also helps to eke out all the detail on that puny 2K DCP (which would probably give you better results than screening a 35mm print on a true IMAX screen).

I saw guardians at the bfi, and it looked OK but was slightly washed out, I know that was not the new system but it was OK I guess

Seems there is some indication as to what may form part of Fox's UHD-BD lineup.

Figures, I just bought Kingsmen on BD. Now to resist buying Chappie or any more Sony Mi4K titles, lest I double dip.
