Will Warner support Blu-ray part 2 ?

And since when it was considered hig for mpeg2 ?

 

You have really bad and short memory, not surprising

This discussion is so lame that i was accused to dont have undestanded what amirm say,
here was what amirm implied with that quote for "real" :

Ok Tom say 40 and Amirm say 50 but it is no near the 200Mbit/sec. aaronpink claim
saying that i have no reading comprension

Obviously you are biased, i said that at lower compression ratio you get a better image quality, so that for both mpeg2 and mpeg4 you can get a better image quality with 20:1 compression than with a 40 :1 compressio ratio.


I stated that with the Dcinema 80Mbit/sec. hi bitrate mpeg2 look stunning and that encoding experience let you to have more easy and cheaper an exellent result so it is not true that you can get the same result with a 40Mbit/sec. mpeg2 and a 20Mbit/sec. mpeg4 with the same cost and time and or no one would using mpeg2 if it was not a codec that easyer and CHEAPER give you an exellent quality at hi bitrate.


Here a quote from Tom :

Thare is something called encoding cost and facilities to obtain a certain quality. You have no experience in professional industial encoding and have no idea of exaclty how much harder is obtain the same quality using mpeg4 or mpeg2, nor you have an idea of the cost of the hw , how much post lab alredy do it and have a experience ecc. ecc.

Is useless talk about theorical number if we don't know if these number will never be reals.


You wont undestand also how useless is wanting to compare a codec made for a lower bitrate situation in an hi bitrare situation like 80Mbit/sec , no one will use that codecs in hi bitrare situation.

You seems to have miss the real mining of this quote :

Why he have hear no one using a 100Mbit/sec. bitrare with mpeg4 also ?

Because you are not trolling enough , is clear why you want this closed

Go to make another offensive Pvt

 

Here is clear how you are a liar. Attack of the clones Dcinema 2048 x 1080 version, what do you had at home to compete with the Dcinema version and that outclassed it ?

And what SVGA digital projector ? The Dcinema is a 2k standard and the first official Barco dcinema projector is a 2k projector.

And you want to compare an lcd $6,995 720p projector with 2200 lumens and 900:1 contrast ratio with an 80.000$ 3-chip DLP™ Professional Series projectors with 2048 x 1080 native resolution, 20.000 ansi lumen and a 2000:1 contrast ratio ?


Do you have an idea of what are you saying ?


This is not an HT projector this is an $80.000 digital theater projector .

Sorry but this cannot appens or it is illegal. You don't know what are you talking about. Dcinema Projector are begin selected and have some spec that are requied for the digital projection.

A Dcinema projector wont even let you to stretch the picture because everithing have to be projected like it is in the original version.

No major let you to project a movie with a quality that is not a Dcinema quality.

That's why Dcinema are growing up slowly, a 35mm projector are a lot less expansive than a Dcinema projector.

HT setups near the 80.000$ price range ?

you wont undertand that the Dcinema Dp100 use the more advanced 3 chip DLP tecnology exist today.

Useless damage control.

I always specifically talked about dual layer blu ray disc and a future four layer blu ray disc.

But you seems to have missed this news :

"AFAIK Matsushita, which has no film library unlike Sony, prefers high bitrate MPEG2 for the time being because of the lower cost in the package contents business.

http://plusd.itmedia.co.jp/lifestyle/articles/0502/13/news002_4.html

According to this article in Feb 2005, Keisuke Suetsugu, the head of Panasonic Hollywood Laboratory who was formerly at Digital Video Compression Corporation and did encoding for famous DVD titles such as Apollo 13 and Star Wars Episode IV, said H.264 requires high engineering skill and tools development to get better image quality while everyone, even without expert encoding skill, can encode with nice image quality by relatively high 24Mbps MPEG2 available in BD-ROM with a larger space."


How many Hd master did you have encoded with mpeg2 and mpeg4 to know exaclt how much hard is to obtain an hi quality mpeg4 encoding and an mpeg2 ecoding ?

Sorry to break it to you but it's up to the major to decide what bitrare use with a dual layer
blu ray disc.

 

And how this classify 7Mbit an high bitrate for mpeg2 ? Using an higer bitrate than 7Mbit for an sd resolution give you a lot more quality.

It is not an hi bitrate for mpeg2, it is just that dvd have a max bitrate limited.

Do you mean in the real word ? Where the result is not a theorical number but a real video and the quality depend on the skills of the encoder, the experience, the maturity of the tollset ecc. ?

The encoding engs seems to think overthise.

But since you wont beleave me :

 

It is more than enough of a skilled encoder eng.

See the post above.

 

7Mbit/sec. is more than enough for an sd resolution to give a very good quality and if you are bitrare limited the eng do it's best to have the best quality you can get for an 8 bit consumer level.

That's said, this dont define 7Mbit at an "very hi bitrate" range itself , 80Mbit/sec. is a very hig bitrate range for the mpeg2 codec itself for a 10 Bit level on the Dcinema, but for an 8bit consumer level 40Mbit is more than enough.

If you want more evidence here is a news :

Not myself included, i don't change my position if an anonymous user state an opinion that is aganist my experience.

I would change my position if a trusthed and experienced hollywood encoder eng say that based on "X" test he made is easyer get an exellent quality with H.264 than with an hi bitrate mpeg2.

But you are right if there are users that refuse to accept even what hollywood encoders engs say about the mpeg2 and the H.264 quality result , it is a pointless discussion.

 

Yes and no, they did not used their own technology , Star wars episode 2 was projected using the same Dcinema format used today, the avica server file sistem plus the barco Dcine Projector.

At first when the Dcinema started for a short period of time was used the Barco Dp50 ,
it was the first official Dtheater projectorand and it had a resolution of 1.3k, you are probably refering at this


But it was only for a limited period of time because it was alredy stated that the Dcinema had to be a 2k standard and the Dp50 was fast replaced with the 2k Dp100.

2k is the official standard Dcinema resolution because it is considerated the resolution needed to match the quality of the 35mm projection.

Like i said the model you are refeng at is the Barco Dp50 and at the time it's cost was 100.000$

Here there is a news about it.

"Brussels- May 14, 2002

Bangkok to Bratislava … via North America. Barco D-Cine Premiere® installed globally for the industries largest ever digital movie release.
Responding to an unprecedented demand for digital screenings of Star Wars II ‘The Attack of the Clones’ on it’s global release on May 16th Barco Digital Cinema has announced the installation of it’s D-Cine Premiere® digital projector in locations as far refollowing quickly on the THX announcement of it’s certification of the Barco D-Cine Premiere® digital projector, Barco Digital Cinema this month has confirmed the supply and successful installation sixteen of the twenty three Boeing Digital Cinema installations in North America and the UK.

So here are the spec of the Barco Dp50 :

3 x high resolution S-XGA DLP Cinema™ DMD™ Dark Metal 3 type , 1280x1024 , 1350:1
contrast ratio

http://www.barco.com/media/en/products/product_specs.asp?element=607

NO it not had a 300:1 contrast ratio it got a 1350 : 1 contrast ratio, see above.

No it is no near to outclass the barco DP50, not even near, sorry.

Sorry the spec existed , the only difference from today was that the Dp50 is replaced with the dp100.

Was alredy stated that 2k was the standard even if for a period of time was used the Dp50 with an 1.3k resolution.

But like i said, your Pj is no near to outclass the Dp50, sorry.

I was talking about the cost of the Dp100 projector alone, 80.000$ is only the cost of the Barco Dp100.

But actualy there is also the Christie cp-2000H , 3 DLP chip 2048x1080 that cost 500.000$ alone.

If there are people that use projectors at the same price range it will match clearly, but
your pj don't absolutly outclass the Barco Dcinema prtojector used in the 2002.

So you are stating that Dual layer blu ray disc will never be out ?

What you say make no sense, really. It is only up to the producer to decide what bitrate using, and it is only a matter of a time once the Dual layer blu ray disc will be out and became cheaper enough.

If a producer want to make a version with the higest video quality you can get he will use the higest bitrate availbe with the disc.

How many producers do you know ?

Sony have alredy stated that they will be using only Mpeg2, and i can assure you that they will use the higest bitrate they can get in the dual layer blu ray disc also.

Have you ever heard of something called "superbit version" ?
