noisy

anyone experience some blu-rays with a lot of noise in the picture?...some are just awesome and some with a lot of noise...could it be my hdmi cables?

I get that, too. I figured that it was the source material (because the noise doesn't move if I pause the disc), but I'd also like to hear what others have to say.

thx for answering me...when i pause the movie the noise doesnt move either so i guess it is really the source...in the same movie some scenes have a lot of noise and then the next picture is awesome and clear...and my 1080i signal for tv is awesome.i think the problem really comes from some blu-rays!.

Can you be much more specific, in terms of which titles, and which scenes in those titles?

TBH, I fear that you might be mistaking natural film grain for noise. Film grain's structure is key to providing detail. If you waxed out this grain, with DNR for instance, you WILL LOSE detail.

Realize that for video (TV) that the signal is at 60hz. Blurays are recorded in 24hz. I don't know if your TV has any pulldown issues. Ok, I briefly looked it up, it says 240hz.

Ok then, is it one of those LCDs that automatically apply frame interpolation? Since 24 fits into 240 ten times, there is the potential to have 216 frames completely faked out by your TV's FI. However, I usually read something like 3 faked frames for every single original frame, or something like that.

If you want to "wax" out any film grain, you can simply buy a VP with DNR. Even some receivers have DNR functions, like the Onkyo 876 for instance.

ok specificaly the blu-ray ''the last house on the left''...this blu-ray has some serious grain in it if thats what you call it..can anyone rent that movie and tell me..or if someone saw it already tell me about it?!

 

[clouso]

btw this movie is insane!!!

I haven't seen it.

Well, firstly, I've seen the trailer, and it looks like a lot of it happens in the dark. Well, it's hard to capture good footage in the dark, because well it's dark and there isn't much light. If they have the budget, they might use faster speed cameras to make it look better, AFAIK.

Secondly, better displays have less inherent noise, as far as I have seen. I've seen two different Panny plasmas side by side on the same feed, and the better unit had less noise during a dark Jurassic Park scene. It even leads me to believe that the VP might be the most significant difference between some displays.

Thirdly, I do wonder if your unit has FI, and it's enabled, and if it is, if it's even defeatable. (I mean how does FI interpret and then reproduce noise to begin with?). I've read that there can* be a lot of artifacting with FI.

Fourthly, LCDs just have a much harder time reproducing black detail, and darker black levels, in general, compared to plasma for instance.


So, is this the only title you really had in mind?

iv seen predator vs alien on my toshiba wich is a led with local dimming btw and if one movie is dark well this is one! and the picture was great so i dont think my display is the problem...another movie that have bad picture also is ''surveillance''...those are the only 2 for now!.

sorry and also toshiba led like mine have very good black level even better then the panny v10 series..I am not saying that just to say it i have read about it and saw some testing results on the web... and what do you mean by FI?

There is a difference between absolute black, and black detail. I'd love to see this test, and I'm not saying you're wrong. Your TV is an LCD. I'm sure you know that, but just in case. The LED is just the backlight, and LCD's still leak light.

FI = frame interpolation. You can find them for sure on Samsung and Sony LCD panels. I've never seen one on a plasma. I've seen it available on projectors.

Basically, there is an algorithm/processor that tries to guess what the frames would supposedly look like between the originals. On AMP on the Samsung for example, there are a few settings, something like low, middle, high.

However, I'm not sure if you can defeat FI on certain sets. I'm sorry, I don't really follow the LCD world. I think they represent poor values. Of course, in a super bright room, it could be nice, but then who cares about PQ fidelity in a super bright room.

But anyhoo, it's probably the title itself, after reading your explanation. Poop in = poop out, no matter how you slice it.
