Get it Right: Blu-ray is 2k.

[stockstar1138]

I keep seeing this mistake being made all over the boards and Im sick of correcting people everytime they make the mistake.

1080p is measured in vertical resolution

2k, 4k, etc. those are measured in horizontal resolution.

Given that blu-ray is 1920x1080, it is basically the same as 2,000 lines of horizontal resolution which is 2k.

no thats not right 2K is basicly 1080p for the scope widescreen aspect ratio.

and 4K is about 4000x2000

Thank you for your quote! But I don't care about that technical stuff or whatever it's called. I'm just a consumer and happy with what I got.

because thats how HDTVs are measured.

HDTVS = measured in vertical resolution

Digital Cinema = measured in horizontal resolution

1080p and 2k are next to identical to each other.

1920x1080p = blu-ray

2048 x 1080 = Digital Cinema

right, the two are basically the same thing.

people on the board keep thinking that there is going to be a jump to 2k and I'm saying that we are basically there with 1080p. I think a lot of people are getting 2k confused with 2160p and 2160p is bascially 4k.

Hmm.. isn't 1920 x 1080 - 1920 Vertical and 1080 Horizontal.....

[miked924]

True 2k is 2048 x 1556...may be close but 1920 x 1080 is not 2k, not in the professional world anyway. Spend less time on these boards and you won't get frustrated with what other people say then you won't start a thread correcting them and in the end being wrong anyway

well acually if we ever have consumer scope tvs then 2K will probably work its way onto the market. And you did way 4K is the same as 1080p which it isn't.

No. Kind of tricky, I had to think about it too.

Took this off of Wiki for you, "The number "1080" represents 1,080 lines of vertical resolution"

[Mikeblu]

2K looks better than 1080p with the black bars as that is its full resolution whereas when you veiw scope on a widescreen set you loose some of the detail because of the black bars.

Right, but 2048x1556 is 2k in its native 4:3 ratio on the film. I am talking about digital projections/HDTVs, which are usually always 16:9 or 2.35:1 if its a panavision projection.

Which turns 2k roughly into 2048x1080, which is so close to a 1080p HDTV/projector that we are going to see the difference if we encoded the blu-rays from a 2k master and had 2k projectors/HDTVs.

Bah, none of this really matters. Panasonic showed myself and Ben a split screen of a film encoded at 1080p and 2K, and you couldn't tell the difference between the two. In fact, no one in the room could honestly tell you which one was 2K and which was 1080p.

thank you, my point exactly, we are basically already there in terms of what we have in our living rooms.

Josh,

How big was the display or screen and how far were you sitting back?

[shock_terminal]

So long as we ar getting all technical.

HD 1080p = 1920x1080 1.77:1 Aspect Ratio or "16x9"

The Spec for recording Digital images to 35mm film are

2K 35mm Film FLAT = 2048x1107 for 1.85:1 Aspect Ratio

2K 35mm Film SCOPE = 2048x1742 for 2.35:1 Anamorphic Aspect Ratio

4K 35mm Film FLAT = 4096x2214 for 1.85:1 Aspect Ratio

4K 35mm Film SCOPE = 4096x3484 for 2.35:1 Anamorphic Aspect Ratio



DCI Spec 2K D-Cinema FLAT = 2048x1080 for 1.85:1 Aspect Ratio

DCI Spec 2K D-Cinema SCOPE = 2048x858 for 2.35:1 Aspect Ratio

Story here.

Our first stop within PHL was the Panasonic Digital Theater. This room exists as a large screening facility where Blu-ray encodes are projected via 2k projector onto a massive one hundred foot screen so that they can be scrutinized for any flaws or encoding errors. As we were welcomed to the event by Panasonic Vice President of Corporate Development and General Manager of the Blu-ray Disc Group, Eisuke Tsuyuzaki, and introduced to many visiting executives, a beautiful 2k projection of Fantastic Four: Rise of the Silver Surfer was put up on the massive screen. As the introductions were completed it was announced that what we had actually been viewing was a split-screen presentation where one half of the picture was the 2k master and the other half was directly from the Blu-ray version of the film. To our astonishment, not a single attendee was able to correctly guess which side was which. PHL strives to produce truly transparent encodes for Blu-ray and this demonstration was a clear statement of just the kind of quality that PHL is capable of.

Thanks Joe!

So basically,you are saying many movies issued today which were scanned with the inital Data Spirit machine, are the one looking less three dimensional on HD ? (ie all masters not 2K will look bad).

Pixels are square. This would only be true if you stood your TV at a 90 degree angle.
