Does anyone have tried to play these movies? When I play the movie, I can clearly see a lot of noise especially on darker areas that something similar when taking photos with high ISO. Just wonder if this is normal for an encoded video or because it is encoded using a low profile?

it's grain.. (when encoding to another format like MKV, it could accentuate the grain more depending on encoder settings, not unlike using unsharp mask on photos)

I notice spiderman always demo on sony TV showrooms, .. dem grainy.. (and I dun mean sandman part) biggrin.gif

But as far as I know if the encoding setting is decent enough, the quality is similar with the original BD source? I've uploaded the photo on the first post

Grain is a part of HD life..like it or not...more so for 1080p that are lower bitrate...sometimes, 720p version look better for some movies because it is not so demanding and easier to get a better pictures with a lower bitrate rather than 1080p version.

There are many reasons to grain.
1)The movie itself.
Older movies tend to grain more due to the limitations of Video camera they were using, especially for those higher ISO shot like moving, panning, dark areas etc. But some movies that are not so demanding have very clear pictures...
Some movies even were shot with grain in them to make those effect like Tiga ratus, BSG....but I'm not sure of Black Hawk Down.
The best movies without grain are like The Dark Knig__, Discovery Channels Documentary etc that are shot with the best video equipment there is.

2)The transfering or converting.
Movies converted to Bluray, then MKV or whatever will occur graining in them depending on how it was encoded. If you check TF2 MKV, there are so far 3 type of bitrate available..about 9000Kbps, 13000kbps, 16000kbps...of course 16000kbps will have the least graining. But it depends also, even for TF2 some shot are grainy especially when they close up the face etc.
Some old movies have 'Restored', 'Remastered' etc version done before/during the transfering..example Fifth Elemen_, Wizard of O_.

3)Hardware.
Cable interferes, bad connection, also effect graining, try to do some adjustment to the routing of the cable and replug back the connectors to make sure fully fitted.

ehh I might be noob but MKV (~4-8GB) is not really the best PQ..Should get .TS (~16GB) or M2TS (~>20GB) for real blue ray experience?

Below is the media info, btw the screenshot is done via PC print screen. That means for 720p with high bit rates is better than 1080p with low bit rates? If for 1080p, what is the recommended minimum bit rate is required to achieve a decent quality? sad.gif Alamak ... if like that had wasted a lot of bandwidth to download those 1080p movies but with low quality.....

Thats normal...from what I notice, most movies before 2003 suffer from this grainy effect more.
Not sure why, maybe they had better cameras after that...I notice this for Tomb Rai___ 2001 and 2003
2001 had graining but 2003 was good.

Have you tired The Dark Knig__ and Speed Race_ those movies look grain free.

As I said, its part of the HD life to have grain...bro..some Bluray Disc movies also grainler...and ppl buy 1 for over a hundred bucks.
