Warner Blu-Ray movies...

[XSilentCobraX]

Does anyone know why Warner makes BD incoded in VC-1, and the sound is Dolby Digital 5.1.
when they make VC-1 and Dolby TrueHD or Dolby Digital Plus on HD DVD?

As far as i know, the first Warner BD movie to get HD sound is 300, in Dolby TrueHD...
cause BD has more space. why not make it in the best possible way.

And many more BD´s are in MPEG-2 and 4, though its a nice picture, i really dont understand why they wont make it all in VC-1 when HD DVD gets it in that, cause lets face it, VC-1 is superior.

One more thing, can anyone tell me the difference between PCM Uncompressed 5.1 sound and normal 5.1 sound, can u hear any difference at all or?


Many Thanks

About the audio, it has to do with the spec, there is not a big difference between then since they are both lossy.

Apparently the former Owner/CEO/chairman where the brain behind the DVD, and since HD DVD is DVD 1.5 you can see that thay ar ea little biased towards HD DVD.

But after Nov 1 they have reason to misstreat BD. Unlese they (BD-A) puts a later date for 1.1 hardware.

We won't face it, because it's not true! All three codecs are capable of near perfect results, MPEG-2 as an older codec technology isn't as efficient so requires more storage for the same* picture quality results as AVC/VC-1.

The best looking Blu-ray movies are encoded with a variety of codecs:

Crank - MPEG-2
Casino Royale - AVC
Deja Vu - VC1
Pirates of the Caribbean 1 - AVC
Pirates of the Caribbean 2 - AVC

*perceptually

Are you telling me VC-1 exists on HD-DVD is better than MPEG2,VC-1 or AVC which does exists on BD,Sorry but really you are dreaming

Hey MAN BD is the powerful format ever existed on HD ,VC-1 encoded on HD-DVD is nothing more than a freak HD,,,,The true HD and Beyound HD exists only on BD..........JUST Watched BD on Full HD display than come back to me.

VC-1 Done for HD-DVD is a lower compression bit rate,VC-1 Done for BD is higher and optimised for BD except for Warner who is doing only identical VC-1 like HD-DVD.Deja Vu and the Queen is the real example with VC-1 higher bit rate just watched them and you will decide by urself that VC-1 optimised for BD is better and superior to HD-DVD .

technical specs: for BD is 48mbs including sound and PQ in HD

whereas the loosing format is 29.5 mbs for both so who is better.

[Ascended_Saiyan]

Uncompressed PCM 5.1 is leaps and bounds above normal Dolby 5.1, because uncompressed PCM (LPCM) is lossless sound and normal Dolby 5.1 is very lossy sound. I believe LPCM has more than 10 times the audio information of normal Dolby 5.1.

Blood Diamond, The Departed, The Sopranos. LPCM

Who told you VC-1 was superior? Amir?

Mission: Impossible 3 was ever so slightly better, in my opinion, than its HD-DVD counterpart. Sleepy Hollow was also an improvement on Blu-Ray. I feel like the thing that is making the blu-ray releases look slightly better (in some cases) is how grain is handled. In many cases, HD-DVD titles all but wipe out any film grain and leave a perfectly smooth image. This hasn't been the case with BLu-Ray. I like how grain is finely and accurately presented. It's very natural and film-like. Sleepy Hollow is an interesting example. It's a very grainy film that was a mess on HD-DVD. The grain often just seemed to devolve into a swarming noise-like image. The blu-ray edition was much more stable and I didn't get any of that "swarming" or movement from the film grain. I found this same improvement with Tomb Raider and Aeon Flux as well.

"Normal" 5.1 sound is compressed about 10:1 from 48kHz 16bit audio
Like a 128kb/s to 160kb/s stereo mp3

A few BD titles have up to 48 kHz 24 bit uncompressed PCM, to date.
There is still higher-resolution PCM.

Please do correct me if I'm wrong, but here's my attempt at the maths...

Uncompressed PCM 5.1 at 48khz 16 bit is 48000 x 16 x 6 = 4608000 bps, which is 7.2 x 640kbps. Stereo CD audio is 44100 x 16 x 2 = 1411200 bps. Dividing by 7.2 gives 196kbps.

However, if by "normal" 5.1 you mean 448kbps as found on DVDs, then I agree, that is close to 10:1.

On the subject of VC-1 I was very impressed with the UK Deja Vu, probably the same encode as the US version. Nice grain reproduction, like you I hate seeing the grain wiped out.

Regardless, the key word there is former, with him gone, there's more per capita Blu-Ray support. Warner plays a big hand in both formats. THey were one of the founders of original DVD and helped develop HD DVD, but they are also one of 19 directors in the BDA and have a profit share in Blu-Ray as well.

follow the saiyan here he speaks the truth ,computes math in his head and meditates while floating ,all at the same time !

Yes your numbers are correct, and so was your assumption

Also, if you listen to multichannel 48kHz 24-bit sound masters at 640kb/s that's near 11:1.

Same as with the VC-1/AVC bit-rate matter. It is high bitrates and great encodes that make the end result the closest to the original picture and sound. If we wanted low bit-rates, we already had 2Mhz VHS and 15kHz audiocassettes.

I think all of us seek the best picture quality and sound to enjoy our favorite movies. The quest for High Definition!

[GasCat]

Supposedly there is an "Operation Hydra" meant to promote Blu-Ray in forums.

I think the HD-DVD group has an "Operation SilentCobra" going on.

To the OP: I find it amazing you need to pose your question given your supposed "knowledge" of codecs and formats. I usually do not call people out but your post deserves it IMO.

ahh right, well thats good information to get :P

Oh no, im NOt saying VC-1 is better picture on HD-DVD, i know BD is better in picture and sound, i was just wondering why the HD-DVD titles get Dolby TrueHD and VC-1 incoded on almost evey title when BD dont.. thats all, BD has cleaner and sharper picture, and more lifelike colors

By Today and mostly in Future BD will get DolbyTHD ,it is confirmed by Paidgeek in insiders Threats and eventually

Now we have many titles using DolbyTHD like Ghost Rider,LETTERS from Warner,Blood Diamond,Stomp the yard,ect...and many more titles on the way.

As far as i know, blood Diamond has PCM soundtrack?

what i hate is warner porting a hd-dvd onto bluray
and like Planet Earth which Looks amazing but could look better if they were real 50 gig blurays

Or they could have kept the same port, used bd-50's, and then the BD version would have been on two BDs, not four, which cuts costs.
