Blu-Ray and graininess ???

photoshop · 26 Apr 2008 at 14:26

Why is it that every time i watch a blu-ray movie on my 37" HD Sammy the picture is grainy (think the technical term is "Noise")?

I've played around with the sharpness setting but it doesnt do much...

And im using the optimum settings for my screen from AVForums...

Any ideas????

PS. Im using a PS3.

As far as I'm aware, the image quality of HD is good enough so that you can see the actual graininess of the film that was used to shoot the movie.

Some films are naturally grainy... Aliens being an obvious example. As such you will not be able to do anything about it.

Which films in particular are you having problems with? It is usual to turn down sharpness to reduce the grain effect. Head over to avforums and see if there are any owners threads about your TV with some recommended settings to try.

Also, some films, like 300, have had extra grain effect added to it.

3:10 to Yuma
X-Men: The Last Stand

I've already been to AvForums and am using the recommened optimum settings. I've also messed about with them and it doesnt help

have you calibrated your tv?

I bought the DVE HD Basics blu ray disc and followed its calibration. Now my Hd picture is a lot better and significantly reduced grainy bits, improved contrast, colour and dramatically imporved black levels.

EDIT: poo just read that you have followesd the settings for ** telly over at avforums. As others have said some films are grainy, I rediced this effect I especially noticed improvements in things like Iwa Jima.

EDIT2: I also realised that some blu ray disks are produced better than others, much like DVD. Some are pap others are outstanding.

Noise is unwanted, grain is in the source and wonderful. DVD's lack the definition and quality of encodes to display and retain grain.

Maybe you can get take some pictures of the TV when it is playing the above mentioned movies to give us an idea of what it is you are seeing?

Grain = Detail. Grain is what you will find if you put film under a microscope.

so there isnt a problem? and what im seeing is just the way the blu-ray is...?

Yes, film has grain, often cinematographers go out of their way to use particually grainy film stock or grain is added digitally afterwards in post. You just don't really see it on DVD.

so blu-ray is that good that the grain from the film shows up from the film reel?
Thats some detail!

Corasik · 27 Apr 2008 at 18:00

I believe that BluRay is able to capture around 25% of film resolution, (Based on 4k digital being considered suitable for large scale projection) so obviously it will capture more of the grain/detail than DVD will which is around 20% the resolution of BluRay 1080.

Most movies arnt particularly grainy, but some like 300 obviously are. Make sure your TV's setup well.

Freeze the playback and study the "grain". If it's still moving then it's noise, otherwise it's grain.
