Heh. And just so's you know, the IMAX print isn't always struck from the negative. When 15/70 projection was still widespread in IMAX cinemas and they had to create hundreds of prints then for protection purposes they went out to the traditional IP->IN->print stages, IMAX being of such high quality that even a 4th gen copy still held up very nicely. But, as with 35mm, they also struck a limited number of superior 'showprints' directly from the negative for premiere engagements and select venues, e.g. the BFI IMAX was usually a recipient of one of these on whatever Nolan film.
By the time we got to Dunkirk 15/70 projection was all but dead, the number of release prints that was needed was relatively small (40-ish I think?) and so they did each one from the negative. That's still 40 times too many that you want to be running your OG negative through a printer but it helps that 15-perf is so stable as a format, even projection is rock solid, so damage isn't a major concern. Regular 5-perf 70mm, on the other hand, was always run from the OG negatives (cut to A and B rolls or single-strand 'auto select' to prevent splices from impinging on the image, the frames being edge to edge) which is why so many large format movies are in such poor condition. When RAH did the last big photochemical restoration of Lawrence of Arabia in the late '80s he estimated that it had been run over 200 times, as well as having been physically recut into various versions with the re-releases over the years. It was in such bad condition that once they'd finished the work and created the restored IPs the negative was essentially "dead" to all photochemical intents and purposes. |

On wiki they list all the UK IMAX 15/70 and/or laser venues here https://en.wikipedia.org/wiki/List_o...United_Kingdom and of the Cineworlds mentioned only the Glasgow one is 1.44, with York not having the dimensions listed. Rushden, Sheffield and Watford are all apparently 1.90, with the first and last having the single-laser 'commercial' setup while Sheffield has the dual-laser GT bad boy. They can be "over 320M" in terms of screen estate but that means nothing w/ref to the ratio. Speaking of which, that the Science Museum is getting the full fat GT laser upgrade AND keeping their 15/70 projection makes me do a sad. It's ****ing criminal that the BFI IMAX is STILL saddled with plain jane 2K Xenon and just gets 15/70 prints for new movies once in a blue moon, I guess those rumours of it being sold off are still giving IMAX the jitters about upgrading it any further. |

It's a money making gimmick. You should be able to make the IE trigger mode optional rather than forced. |

Yeah I just find myself just getting irritated with these AV codec companies and this half axxxx "war" where there can never be a "winner" and it is just continual consumer loss. So take Dolby. Arguably the better audio format, but on the videoside they be total xxxts and make a decision that nits are everything so they forcibly disable LLDV for every single 4k projector, from a "lowly" $5k projector to a $100k Barco. And DTS. The lesser audio format, and they go and deceive consumers thinking they are getting an enhanced picture, but what it really means is a lower grade audio format, nothing more, nothing visually. Just utterly disgusting. They both suck.

I did hear of some people forcing LLDV on PJs using a device to alter the EDID being sent to the player, so the player would send out the pre-mapped 12-bit stream (essentially HDR12) and all the PJ had to do was display it, but have they managed to stop that practice somehow? |

Yeah the EDID trick for Low Latency Dolby Vision works (I got mine setup last weekend), and it is pretty good. I'm not sure (given how it works) how they could stop it. I guess if they got all manufacturers to do firmware upates to no longer allow LLDV (if that is even possible), or for new models just don't allow it. LLDV is just basically the player implementing the DV DTM. I was pretty impressed watching The Last Jedi with it. I have to figure what titles I have with DV. On the Oppo and Sony players you can get it to put blu-ray and HDR10 in an LLDV container, so even those show as DV. In my opinion, all display device manufacturers should just implement DTM for HDR content. I can't imagine in what world of logic you would design a device that you know that can only display say 1000 nit, and the image says 4000nit, so you just clip. It is as silly as having an amp that you can't lower the levels so if the signal is too loud you just get clipping... |

So you're seeing quite a difference with this as opposed to how you were set up before? |

And no, the certification is not centred around "needing nits" otherwise the 108-nit Dolby Cinema version would be shit out of luck. The issue with DV and consumer projektion is that everyone's viewing environment is different owing to the unique combinations of projektor, screen and ambient light levels. I mean, I understand the frustration here especially because the whole "golden reference" thing was quietly dropped by Dolby owing to the panel variations on direct-view displays, but clearly they feel they can still set a baseline for TVs that's more accurate than not, whereas they can't possibly legislate for all the unique interactions in the consumer projektor realm. |
