it cant be the hdmi cable, the hdmi cable is a digital connection, so if there was anything wrong with the hdmi cable it will just lose signal. never heard of an hdmi cable adding grain artifacts

many films purposely add grain to whether or not its cg, it has to do with a study that most film goers find grain more comforting while no grain = sterile lifeless.

I suppose its similar debate audio has with cdds versus lp.

if you take notice, even completely cg rendered films include some artificial grain.

however with blu ray, depending if its single or dual layer the grain may be compression artifacts.

compression artifacts and simulated grain are too different things.

 

I don't entirely agree with those points. It is possible to have an inferior HDMI cable. Just because it's a digital connection doesn't mean that you will get only two results...no picture or perfect picture. If that were true, there wouldn't be $10 HDMI cables and $75 HDMI cables of the same length. As far as some movies adding "grain"...that may be true for 300, but not for Planet Earth. That series (when viewed in true HD) looks like you can step right in to it.

 

generally discovery documentaries are filmed with a digital 1080i camera straight out. Thats a documentary however not a movie.

chances are.. if it was in the theater its going to have grain nartural or artificially imposed.

in regards to hdmi, if it were an analog connection, I would understand. analog signals are affected by interference, while hdmi cables just transmit "om" "off" 010101011000011

so if there was a drop in signal it would just not show a picture, these cables are not affected by outside interference like analog cabing.
However I suppose the build quality and bandwidth will affect the performance, but again the difference you would see is a picture or no picture, not a picture but with added grain or compression artifacts.

I actually use some cheap $20 hdmi cables for my ps3, because I prefer thing and flexible over thick and unwieldly. hdmi connectors do not have support screws like dvi, a thick and unwieldly cable handled improperly can break your hdmi input.


the reason why there are $10 and $75 hdmi cables has to do with build quality and reliabilty, not performance. someone with a $10000 system is not going to want a $10 hdmi cable, however both cables will yield virutally identical picture performance. but the more expensive cable is built more solid.

in regards to hdmi, what it comes down too is the higher priced ones are built better.
regardless its always a good idea to make sure the cable you are purchasing is labeled 1080p bandwidth and hdcp compliant if you want to make sure you are getting a cable that promises no performance comprimise.

Ya know...I never really thought of it in those terms. What you are saying makes sense. I'm so used to always buying high-end cables and speaker wires to get the best possible signal transmission, that I guess I was applying the same logic to HDMI. But with it being a 100% digital signal, I see your point. I'm gonna do some reading on that one!
That brings us back to the original post and his problem. If he has a HDTV that can display 1080p, a blu-ray DVD player (through a PS3), and "Planet Earth" on Blu-Ray disc, why would he have a poor picture? He claims he's connected straight from the PS3 to the TV via HDMI. That picture should be pristine. Any ideas?

 

Could it be the PS3 and just a bad blu-ray?

 

well I think the movie in question is 300 and not planet earth?

I have yet to get 300 since I need to replace my projector bulb, so no movies until I can afford the replacement.

there are several factors that contribute to the graininess... if all movies but 300 look fine, than its the movie.

if all movies look grainy than there are some things to look into. Make sure the tv is a native 1080p display. if it is, than look into the tvc settings. Make sure that you have noise reduction setting turned off.

other factors may be that you need to have the tv set to pixel for pixel map, so you dont have an additional scaling in between. blu ray transfers are not as good as hd dvd btw, I use both formats and notice that hd dvd transfers as a whole look better than blu ray. Many blu ray movies seem to suffer from more digital artifacts while hd dvd has none.

so it could just be the transfer.

but honestly what I think you just need to do is as set up the tv, and calibrate the settings. i.e. adjusting the sharpness, brightness and contrast will help minimize the artifacting you see.

btw what tv are you using?

 

here is a pic I snapped a while back from the hd dvd aeon flux, you can see where there is subtle grain which is normal





heres a snapshot of some blu ray and ps3 hd demos





and just for kicks 360 :D

It's a Samsung 5076 slim DLP 61 inch

 

that tv is full 1080 native.

is 300 the only one thats giving you problems?

try to turn off digital noise reduction, that may help.

i'm a home theater nut, i was on hi def back in 2000, i 'm curious to see if you have solved this problem.

 

not all of planet earth was shot in HD.... is it all of PE that's "grainy"?

and do you have a quality 1.2 or 1.3/a HDMI cable?

 

the difference betwen 1.2 and 1.3 is deep color
not grain

 

any updates?
