Lucy - Trailer (Universal Pictures) HD - YouTube


….asking about what would the resolution of the DCP be, given the tech specs….http://www.imdb.com/title/tt2872732/...ef_=tt_dt_spec

Answer – expect your local D-Cinema to get a 2K DCP for this feature film.

Or, to be more precise, as follows:

Lucy DCP

Image Format: 2048x858 (scope)
File Size: 112GB
Audio Format: 5.1
Run Time: 1:33:41

FYI, I also tried the Divx player and downloaded the HEVC plug in as well but that won't play the 4K TS HEVC file either

the Divx player can play the other 4K files like mp4, quicktime

Damn so no 4k and no Atmos? Why the hell use Sony/Red 4k camera? It must be just for the IMAX shots.....

Plenty of movies have used 4K+ capture with a 2K final. The Hobbit films for example.

Luc reminiscing about The Fifth Element, see last paragraph….http://collider.com/lucy-wondercon-panel-recap/

I wonder if that particular “redneck” theatergoer he refers to has since evolved in his thinking? If not, the poor fellow may have suffered a heart attack by now.

P.S.
b.t.w., the release date for Lucy has changed since that article was written. It's due out next week.

FYI, if you have a 4K Video HEVC that is mkv, it plays with VLC and Divx player

but still the 4K HEVC TS file fails on every software I have tried

Somebody should specifically ask Luc that on Thursday evening…..http://www.americancinemathequecalen...content/lucy-0 and also which cameras' ‘look’ (of the 3 brands) he preferred with colors, etc.

In the meantime, this clip may provide a hint as to when/why the Sony F65 was utilized in comparison to that of shooting with the lower rez-ed Alexa….http://www.imdb.com/title/tt2872732/...b-vi2663492633

In percentage, how much better is 4K better than 1080p?

[detroit1]

There is no way to give an exact percentage
sometimes there is a noticable difference and other times it is very small depending on how far you are from the screen

and the type of content itself matters a lot too

Are there still any members here who have dedicated themselves to the noble pursuit of saving lives and stamping out disease (often at a personal cost to spending quality time with their families due to the demanding nature of the profession) who have expertise in the area of….da brain…like Brain ‘Sturgeon’…. https://forum.blu-ray.com/showthread...s#post2024141?

If so, anybody know what we’re seeing at ~ the 20 sec. mark of the Lucy video clip linked to in the above quote?

Engage yourself in the above post while I take 10 min. or so to type up something substantial explaining the current state of 4K affairs. Detroit's on the right track.

I know of no scientific study that has measured the value in that fashion. You would have to rely on anecdotal evidence from fellow 4K tv owners.

What I can tell you is ….recognizing certain caveats or even possible limitations/flaws in previously presented European scientific testing, evidence has been presented that there is a statistically significant difference between 4K and 1080p and it has been measured in “grades” on a 5 point grade scale. 4K has been determined by such scientific testing to show a ½ grade difference better picture quality than 1080p at a 1.5 picture height screen-to-eye distance. Think of that sort of like 1080p being ‘good’ and 4K being ‘very good’.

Since it is assumed by investigators that many consumers will: 1. refuse to alter their current furniture arrangement to take full advantage of increased spatial resolution (4K), 2. won’t ever use larger desktop monitors in their offices/studies where they normally sit closer to the screen anyway, 3. not have any children who enjoy sitting on the floor closer to the TV to watch their favorite shows….testing was also done at the ‘normal’ seating position or screen-to-eye distance of 9 ft., with a 56” TV and at that distance, there was about a ¼ grade picture improvement for 4K source over 1080p source. Think of that sort of like the difference between ‘very good’ and ‘very, very good’.

2 caveats regarding the methodology which lead to the above results though -

1. This testing was done presenting scenes with uncompressed progressive source. It has been theorized (even conceded by the investigators themselves) that the improvement gap between 4K and HD might have been more significant if HEVC (or, for that matter, AVC) compressed contents had been used.

2. This was not a ‘side-by-side’ comparable 1080p display (less pixels) vs. a 4K display (more pixels). The 4K source was fed into a 4K tv….and… the 1080p source (downconverted from the same 4K source) was fed into the same 4K tv. Some people, such as Charles Poynton, believe that 4K tvs ‘work’ better than HD tvs because the 4K display pixels are so invisibly small that they don’t contribute any visible aliasing by themselves. So…in regards to those previous European tests, perhaps if a 4K display had been directly compared to a 1080p display; likewise, as in caveat #1, a larger improvement gap in picture quality difference may have been demonstrated between 4K and HD.

Anyway, for comparison purposes, other testing has shown HDR and HFR to offer a full grade improvement in picture quality, i.e. ‘good’ to excellent…independent of close or ‘typical’ viewing distances.

P.S. ‘Grades’ may seem a funky quality scale in comparison to a specific numerical value but there is some science behind it, see Fig. 6 around half way down the page in B.T.500-13…http://www.itu.int/dms_pubrec/itu-r/...1-I!!PDF-E.pdf

If you avoid the fake download links, and make sure to uninstall any codec software, you could try the K-Lite Codec Pack.

No brain surgeons left in the house? Ergo, no Lucy joy on the axial section through….da brain? Well, it’s certainly above the level of the sella. o.k., since we probably don’t have any rocket scientists on staff either, a question to ponder for the engineers (de-greed and un- de-greed). Do quality medical grade LCD displays possess at least 10-bit panel drivers and 10-bit processing?

Capturing at a higher resolution yields benefits even when mastering at a lower resolution. Hence why the image quality of 70mm is apparent even at 2K/1080p.

In most cases a director/DP is hopeful that they'll be able to master in 4K (see: Kosinski and Oblvion), however it can be difficult to pencil out if you don't have the extra time in post, or are cutting it close with your budget.

Additionally (although not mentioned in the interview with Lucy’s DP just posted online yesterday by fd times - http://www.fdtimes.com/2014/07/24/lu...-arbogast-afc/ )….if the image wasn’t shot exactly the way the Director would have wanted it, or, in retrospect, ultimately desires it, the post house can pan off the shot much easier with 4K acquisition in order to fix it….i.e. reframing. That helps a lot sometimes.

I'm under the impression that reframing occurs during the DI process, thus, after the files have been compressed to 2K. Correct me if I'm wrong, though.

If you wanted to see almost the same dramatic difference in clarity like Blu-ray was to DVD then you'd have to compare 8k to 1080p!

Just like Blu-ray was 16x the resolution of DVD, 8k is 16x the resolution of Blu-ray! The comparison would be a little different though? Most DVD's where Bit-rate starved because of storage space issues but Blu-ray's don't have those issue unless companies choose too!

Most Blu-ray discs have a lot of wasted space do to lazy mastering or because it's a direct port from the same DVD master with no editing so they can make a quick buck!

Blu-ray is 6x DVD, not 16.
