1080p/24 - Blu-ray Forum

slpbird · 08-30-2007, 03:13 PM

Looks like alot of people will be in line to purchase new televisions being that not many can display the 1080p/24 because most tv refresh rate are 60 htz.

I don't think panels have a fixed refresh rate. But, they need to accept 24 Hz input, or do inverse telecine on a 60 Hz input.

DLPs obviously have a refresh rate.

So far I have watched all my blu-ray movies at 1080i @ 60Hz through component cable and was still astounded.

Can anyone tell me what makes a movie so great at 24p on a 1080p screen?

CAB · 08-30-2007, 06:25 PM

Looks like the Sony A3000 SXRDs are shipping with the Bravia engine that does 120Hz refresh and take the 24Hz input. Yummy! I bet these sell well this holiday with all those HDNA displays.

The difference between using a native 24p signal and a 3:2 pulldown will be minimal. I'm sure it is noticeable, but it is not worth the price of a new TV just to have it, plus the lack of discs that support it as well.

Assuming your set does not inverse telicine (IVTC) back to 24p, the difference would be a smoothness in pans. An even cadence instead of the 3:2 frame cadence of 60Hz.

And if your set is actually 1080i (CRT) then 1080p gives you the full 1920 horizontal (versus perhaps ~1400) and maybe a touch better vertical resolution too.

You lost me on that "lack of discs that support it as well" part. Aren't all BDs mastered at 24 fps?

It's mostly concert, and some documentary discs (the Atlases for example) that are in 60i because they were shot that way. All movies I have and even the Planet Earth Warner/BBC Region A disc (which was broadcast in 50Hz in Europe) are in 24p

The difference is minimal but it's a difference, movement is smoother, a more "filmlike" look, and grain might be a smidge less noticeable. Every little bit (1080p vs 720, HDMI vs component, 24p, high bit-rates, etc) adds up in the long run, so it's nice to have if you can get it. If not, don't sweat it out. Getting 1:1 1080p I think is more of a priority for example

gvortex7 · 08-31-2007, 06:42 PM

I watch my movies via 1080i/60 and I'm quite content with the picture quality. Unless I see a drastic difference with a 1080p/24 setup, I am not upgrading both the player and a new display.

All BDs are authored at 1080p/24.

kitchen-space · 09-28-2007, 06:23 PM

My Mitsubishi DLP only has HDMI 1.1, and my Denon A/VR 4806 only has 1.1, so once I purchase a Bluray player, will I be able to view in 1080p/24Hz ?

WickyWoo · 09-28-2007, 06:34 PM

As long as your display and player support it yes

your TV has 2 b able to do 24Hz

kitchen-space · 09-28-2007, 06:43 PM

My TV is a 2007 model Mitsubishi WD65731 DLP. The spec sheet doesn't say anything about 24Hz.

Although the new 2008 833 series does say HDMI 1.3 and 1080p/24

wem003 · 09-28-2007, 06:55 PM

I just bought a Sony KDL-46V3000 about a month ago. This TV is 120hz and accepts 1080p/24.

Watching Casino Royale in 1080p/24 is simply amazing. The places where I really notice a difference are high detail action bits - like the bubbling water at the end of the movie - looks like I am watching it through a window - there are no artifacts and the motion is so smooth.

Your mileage may vary, but since we needed a new TV anyway - I am so happy we spent the extra money.

Yep, and if they'd just offer a free Blu-ray player and the customer's choice of two free Blu-ray videos with each set, it would be "game, set, match" time. And the same thing with Samsung with their new 120MHz HDTVs.

Blu-Style · 09-28-2007, 11:51 PM

I guess...
on these few points you can see what makes the difference between 1080/24p and normal 1080p

• The scene with the crane on "Casino Royale", (the fast camera movements)

• "World Trade Center" while the bus is driving across the road

• And some fast credits at the End of some movies

BTBuck1 · 09-29-2007, 12:11 AM

24p native is over-rated IMO. 3:2 Pulldown judder is only ever noticeable when the camera's are panning slow toward something (which is a rare shot in a film with actors) and then notiecable again during the credits....does anyone care about the credits?

I could see for nature docs etc, that this would be useful, they have alot of shots that would benefit from this, but many of those are shot in 1080i/60....so again very limited return on investment.

I say if your buying a TV and it falls under one of the multiples of 24hz such as 72,120hz etc...and it isn't much more money to upgrade (under $300 or so), then go for it. I certainly wouldn't sell a perfectly working 1080/60 set though just for this feature. And there are IMO more important features to look for when buying a tv, such as:

*Will this TV de-interlace properly?

*what is the contrast ratio?

*Whats my TV's processor do with the resolution when objections on screen are moving? Why this is important:
(some TV's can drop the resultion by up to half when the objects on the screen are moving) Your HDTV could become an EDTV during scenes with motion

These are more critical things, since they are noticed ALL THE TIME.

I am sure this will be a relatively standard feature over the next couple of years, Til they find something else to over-hype and sell us on.
