4K Movies Releases

Penton, you are always a wealth of information. Thank you once again, my friend.

One thing that few know about is that the max. data rate for 2D 24fps imagery has been set at 250 Mb/sec by the DCI (http://www.dcimovies.com/specification/) and many D-Cinema experts believe that a higher data rate should have been spec-ed from the get-go for large format (65mm source) 4K.

If that theory is true it means that this lower data rate is softening or making the large format movies more blurry than they should be when you see any 4K DCPs of those films than if a higher data rate had been spec-ed.

I’ll answer all those PMs here en masse with a F/U film-making post. Just give me a little time to hunt down the appropriate visual aids so I don’t have to do too much off-topic typing. In short, it’s all motor-sickle related. In the meantime, to give all those PMers a little idea as to what it means, I recently made this post in reference to The Great Escape…. https://forum.blu-ray.com/showpost.p...&postcount=677

^ So the F/U post being...as a young whipper-snapper I was inspired at a very early age to ride (and race) off-road motorcycles by the likes of Steve McQueen, Malcolm Smith and a man named John Penton, hence Penton motorcycles (which he introduced to the U.S)…hence the avatar. Little background – http://resmarket.com/pentonmovie/ <- the pic at the end of the clip is him going flat out during a special test at the 1969 ISDT at Garmisch-Partenkirchen, Germany.

It may not be shooting in 4K rez like the rest of the films listed in the previous posts in this thread, but at least it’s shooting …http://www.kickstarter.com/projects/...ett-rela/posts

To give you an idea of how much compression, the maximum allowed data rate for both 2K and 4K DCPs for JPEG 2000 images @ 24fps is 250 Mbit/s….which equals 31.25 Mbyte/sec.

Now compare that to the fact that a single uncompressed 4K image (at its original maximum resolution and 12 bits per component) requires about 39.8 Mbytes of storage space. This translates to a data rate at 24 FPS of 955.5 Mbyte/s . That amount of data is just not practical (too high) to be handled in the distribution to and projection of theatrical motion pictures…hence the need for compression.

And so it begins on a larger marketing scale now…….

ATTENTION Locals,

Registration is now open and FREE...until May 25 - http://www.cinegearexpo.com/category/register

At the very least you can get to see a complimentary screening of the 4K DCP of After Earth with an accompanying panel discussion - http://www.cinegearexpo.com/77/

Given the fact that Arsenal qualified for the Champions League today

(now they just have to spend some of that money coming in on some truly world class players), I'll see if I can think of a *shot in 4K commercial* containing at least a tiny reference to the game of football.

Well, they did sunderland a favour last week so they deserve it!

He had an interview with Gary Reber (who also always gets it wrong) when DVD launched and they sat and lamented how their beloved LaserDisc format was being discarded in favor of this new "inferior" format. They actually proposed a "Super LaserDisc" format using 12" discs and digital video encoding! Reading that interview made me facepalmed so hard that the palm indent is still on my face after 15 years!

I was able to get through about the first 10 - 15 minutes of Joe’s interview. Of the portion I listened to, it was quite strange. Yes, as expected, he did make a big deal out of D-Cinema 4K vs. consumer 4K,--- which, as I said on the last page, is something that we here have been discussing the proper way to do the conversion (crop vs downscale) for over a year now…..so nothing original from him on that count.

Then, what came next was even more odd. For instead of simply answering the interviewer’s question as to how close do you have to sit to a 4K tv in order to derive benefit, Joe discusses the situation from a completely different perspective. He addresses the concept (based on his testing) that in order to have a 1080p display which is appropriate to see what’s in the picture, he says it must be at least 6 ft. diagonal….for just a 1080p set….no matter how close you sit to it!

So, to all you owners with 1080p tvs smaller than 72”, I’ll have you know that you all have been wasting your money all these years because you didn’t buy the proper-sized set, no matter how close or far you are sitting from it….Don’t even ask what screen size he thinks you need for 4K “to truly see what’s in the picture”.

I have a novel idea for Joe, instead approaching the value or benefit of 1080p or 4K in an ass-backwards fashion and basically determining how large a screen one needs to *break the codec* by magnifying the encoding errors so he and his friends can see them….why not do a simple straightforward test which would be more practical to consumers, like, for instance, determining how far away from the screen viewers can sit and still see a measurable difference between 4K and 1080p content. And use the best case scenario….meaning native 4K out of something like an F65 camera, because it will be a given that with the implementation with either AVC or HEVC compression for consumers, there will be at least some loss in PQ from the native uncompressed source. I mean it’s not going to get any better than a native 4K source.

I’ll spoon-feed the method for the experiment – run in native 4K into one TV….well, of course first crop the native 4K content to consumer 4K ( e.g. 4K -> 3,840 pixels), without making a big deal out of it and going on a talk show. Make copies of that test footage and down-rez it to 1080p (with the best converters commonly used throughout the post production business) for the sample for the HD portion of the 4K vs HDtv shootout viewing distances….and reveal to people on the next talk show what you found out…..and do it with no less than 50 untrained volunteers (typical consumers, not 'video gurus').

But, alas, some people will already know the answer to that.

But with regards to SNE...for a different reason than some expected - http://www.foxbusiness.com/technolog...-spinoff-plan/

Saw a 4K demo today at Best Buy for SONY. Not all that blown away, it wasn't all that much better than 1080p. There was a difference, but not much.

I saw the same thing when I saw the LG 84" with 4K.

I remember people saying the same thing about bluray demos. The reality was very different. Different people's perceptions play a big part, of course.

Have you seen a 4K demo yet?
