Imax Debuts 4K 3D Digital Camera on Transformers: Age of Extinction

http://en.wikipedia.org/wiki/IMAX#3D_digital_camera

In 2011, IMAX announced a 4K 3D digital camera with the similar wide resolution of regular IMAX film cameras. The camera was developed alongside Vision Research and AbelCine, integrating two Phantom 65 engines. A prototype camera was used for the documentary Born to be Wild, in which approximately 10% of the finished film was shot with the system. It has been said that the company has no intention of replacing the higher resolution film cameras with the new digital camera, but the latter can be used in scenes that require a lightweight or relatively small 3D camera in order to film it without issue. Currently while IMAX has completed the production camera and has been placed into service on several films, there are no plans to produce an IMAX film using solely the new digital system. The upcoming Transformers: Age of Extinction will be filmed partially with the Phantom 65 IMAX 3D camera.

Peter, if you need more convincin….see if you can catch a rerun of yesterday’s Holland vs. Spain match on ESPN or ESPN2. Otherwise, if even that won’t do the trick, then we’ll consider sending over the Victoria’s Secret Angel (Adriana from Brazil) and her assistants to your man cave….

The video compression rate is not a fixed value and it depends on the resolution and frame rate. HEVC supports larger coding blocks that more efficiently encode higher resolution video. Also I have read that going from 60 fps to 120 fps adds less than a 20% increase in bit rate due to the higher correlation between frames.

While bit rate is a factor so is bit depth, color space, dynamic range, frame rate, and resolution. I think there are several ways to improve consumer video that would be more noticeable than having a huge increase in bit rate. I hope that 4K Blu-ray supports 100 GB discs but would be disappointed if 4K Blu-ray is not competitive with UHDTV.

I think your target is unnecessarily high.

Based on reference software (HM v10.0) in which 5 different bitrates were tested from 4Mbps to 20Mbps, you can see that perceived video quality (as viewed on a professional 10-bit 56” monitor by ‘non-expert’ test participants) starts to level off in the “good to excellent” region somewhat at around 15-16Mbps…



Problem is, while the above experiment provides a good approximation of HEVC codec capabilities (i.e. reference software, code bases), it is believed by people in the business that with the current state of commercial encoding, that the above UHD parameters which I mentioned previously would require on the order of 25 Mbps or more for Rec.2020 compliant 4K 60fps delivery from stored content (in order to provide a compelling picture [larger screen size ( > 56”) might require a tad higher bitrate]. 4K Blu-ray (physical media) could deliver this.

As an aside, from more of a business standpoint for content providers interested in adopting HEVC, it is expected that it will take about 2 years to achieve just 20-30% encoding efficiency (not to mention ~50%) vs. H.264 encoders for nearly the same encode time.

As H.264 is twice as efficient as MPEG-2, that is equal to 48-68 Mbps MPEG-2 bitrates.

Blu-rays therefore typically have 8x the bitrate of their DVD equivalent.

Compression numbers just don't work like that.


You also forget many early BDs used MPEG2 compression and their bitrates were nowhere near 6x (much less 8x) of DVD.

There are no kids in my house and my family knows better than to try and spoil match results for me. The last time was....unpleasant.

It is a huge challenge. When my team is not playing on a Saturday sometimes I avoid all scores so I can watch the highlights show on Saturday night. It is extremely tough to go the whole day avoiding scores.

....as they say, best laid plans.

singhcr, matches of extreme importance demand extreme measures, e.g. I’ve taken a ½ day off in order to watch the BIG one (http://ftw.usatoday.com/2014/06/us-soccer-ghana ) live and in the meantime I’m currently through the 1st half of Portugal vs. Germany. So, what did today’s Portugal vs. Germany match remind me of, so far?

While watching and suffering somewhat through the current broadcast quality [HD LDR (low dynamic range)] of the match, the value that future technology (HDR as an enhancement parameter to ‘vanilla’ 4K) holds….https://forum.blu-ray.com/showthread...ws#post8520754

Neutral postings about matches without overtly (or even hintingly) revealing scores or outcomes are the best way....since we're all on different schedules.

Nobody yet?

Keep pondering. A little background…
Two sets of primaries were proposed. The Japanese proposed 635, 532 and 467 nm (635 and 532 fit with current laser technology). The Koreans proposed 625, 531 and 467 nm, because 625 and 531 nm are on the equi-hue lines of the red and green primaries of LCD and OLED.

Excellent chart you put up; you should post that all over the internet
most people have no idea about bitrates; they assume higher is better but in reality once you hit a certain point, it means nothing to go higher and higher
I have videos at super low bit rates that are better quality than ones at higher rates; once you hit a certain quality point, going higher does nothing except make the file bigger

For the sake of those who recorded the big match but still haven’t gotten around to watching it, I will spoiler-ize the outcome and my thoughts here -

http://abcnews.go.com/GMA/video/team...ghana-24170237

I’m so proud of our National team and happy for U.S. soccer, in general, since there may be some young little U.S. citizen somewhere that watched yesterday’s match and who may have been inspired and has the raw talent to become an ‘American Pele’ and move us as a nation towards becoming a serious soccer/football contender for the trophy itself….someday.

Now that the personal euphoria has subsided (and I’ve cleaned up the beer I spilled on the carpet in my man cave after the winning goal), we are on course for the strategy to work - https://forum.blu-ray.com/showthread...rs#post9302575 but, I must say, I am rather concerned for us against Portugal come Sunday because I think unless we step-up….drawing with Portugal will prove even more difficult than was beating Ghana. Plan on *bombs away* at our goalkeeper.

^ I will not un-spoiler-ize the above for at least another 24 hrs., then read at your own risk. Since it’s been several days now since the Italy v. England match, as an aside to Steed, don’t be discouraged, there’s still hope . England has shown MARKED improvement since the last World Cup and Sterling is a shining star.

I appreciate that. When I first saw that people were posting stuff about the games, I did as the father did in the Hyundai ad- I covered my eyes and started making noises so I didn't see anything.

I suspect it is a good audio summary for new readers to our thread (4K Movie Releases).

Personally, I don’t have time to listen to an over hour long interview during the World Cup tournament and I would bet that nearly everything on it has already been discussed (accurately with specifics and in detail) on prior pages of this thread weeks/months ago….esp. in exchanges between myself and Richard Paul, Peter, Kris, etc. Not to mention the fact if you desired it directly in writing from the horse’s mouth (the SMPTE UHDTV study group http://www.worldbroadcastingunions.o...e%20(NBCU).pdf ) a heads-up was given just prior to the report being published online…https://forum.blu-ray.com/showthread...tv#post9037061

With a follow-up link to the download (which is free to even non-SMPTE membership…now 3rd one down - https://forum.blu-ray.com/showthread...te#post9044779 to the final report (an initial report was issued last Sept., also linked to on this thread) and I highly recommend it to those interested in the UHDTV topics.

I’m a big advocate of SMPTE especially since there has been development of remote access (telecommunication) to technology committee meetings, which in the past required substantial traveling in order to contribute live and in-person. With that, as well as other improvements, I think that SMPTE has discarded its past reputation (rightly or wrongly) of being an *old boys club*.

But to play devil’s advocate for a moment on this topic, the *power*, if you will, does not reside with SMPTE as their recommendations are not akin to a regulatory organization. The *power* resides with the content producers. For example, in the professional digital cinema arena, there are actually two types of DCPs…the newer one being an SMPTE DCP version, if you will. If studios really desire to release SMPTE qualified DCP movies (instead of interop versions), they have the power to do so, first by getting on the stick and actually implementing the related SMPTE test material and authoring guidelines.
