V eni drugi temi sem zasledil debato o kvaliteti BDjev. Kot mnogi sem tudi sam bil prepričan da če je film na BDju potem more bit slika kristalna, taka da sosed onemi ko ga povabim na ogled kakega filma, VENDAR  Smeško  je zrnasta slika nekaj povsem normalnega če je film bil posnet z navadno filmsko kamero(nekatere scene posnete z digitalno kamero so nalašč tako posnete umetnost pač Smeško ). To "zrnje" je sestavina filma na katerega je slika posneta. Na DVDju se ne vidi, na BDju pa zaradi visoke resolucije postane vidno.

Ta modrost seveda ni zrasla na mojem zelniku http://www.ps3forums.com/showthread.php?t=55880

I know some of you think that when a HD DVD or Blu-ray disc looks "grainy" its because its a poor quality release or was shot that way on purpose. Well im here to clear a few things up for you. While one of these is slightly correct the other is not at all. Some directors intentionally shoot things in a certain way to add this grainy effect, but most of the time it is a symptom of 1 thing and 1 thing only, FILM.

When shooting on Film, like most movies are it is made of of certain chemicals and properties that make it what it is. Without this mixture of properties we would not have FILM as we have it today. There are certain properties of the film that come out in the final product, it is not something we can ignore or escape from. Film is partly made up of a metallic silver compound derived from silver halide. This is basically why it is there, it is what makes film what it is. They go hand in hand because they are 1.

The whole idea (and this is when Home Theater enthusiasts started, mostly before any of us were born 30 years ago) of a "Transparent" experience when bringing the movies on on HD, they allow for a closer representation of what the actual movie was meant to look like. With lower resolutions and less color and accuracy in regular DVDs (SD-DVD) it is a lot harder to see the grain that is associated with film. With the newer discs, in 1080p... or any HD resolution for that matter it comes out of the film onto your screen a lot easier, and a lot more. This is a basic explanation.

I'd hope to change peoples minds, because a lot of people think that HD should look "clean" all the time, when in fact its not that way at all, if you were to ask for all HD DVDs or Blu-ray discs to be "clean" and "grain free" you would actually be doing a lot of harm for a few reasons, the first reason is that this ruins the original intent of the director (whether they wanted it grainy or not) becuase you would have to apply all sorts of filters, effects and editing to the finished product since "Grain" IS film, its not compression or bad capturing, its a part of film, it is film. You cannot have one without the other.

I can answer more questions, but I would hope people realize that "grain" on Blu-ray or HD DVD is actually a good thing, its shows that the movies are that much closer to their original product... FILM.

Ja to je res. V bistvu se kar nekaj režiserjev odloča za tako vrsto snemanja. Primer takega filma je npr. Black Howk Dawn od Ridley Scotta. Pri višji kakovosti zaslona, pride ta zadeva še toliko bolj do izraza.
So pa dejasnko filmi na BD, ki so slabe video kakovosti. Ta pomanjklivost se kaže kot neostra slika, ki je zlahka primerljiva z navadnimi DVD filmi.

Lp, Jan
