Is it true that blu-ray movies use MPEG2 while HD DVD uses MPEG 4?

[WriteSimply]

Not true.

BD uses MPEG 2, 4, and VC-1.

[Blue]

Yes and No.
Some Blu-ray movies are in MPEG2 some in MPEEG4 (pt10) otherwise known as AVC and even some in VC-1. MPEG2 (upgraded for HD, just as MPEG4 was) is an excellent CODEC, however it is not very efficient hence more storage space is required. For shorter films this is not an issue for Blu-ray, hey if ya got it why not flaunt it. With computers different compression algorithms work better with different sorts of data. It seems the same is true with film. MPEG2 works really well with high grain content while VC-1 is best suited to a pristine really clean film, a typical example would be a cartoon like the Simpsons. Naturally reduce the data rate with all CODECS and quality decreases.

Hello,

BD can use three codecs MPEG2,VC1,and MPEG4 Known as AVC

Blu-ray disc can maximise the bit rate go up to 40mbs per second it Depends on the title.

Most warner releases are using VC1 lower compression equally or let's say identical to HD-DVD releases by same company.

SONY FOX BUENA VISTA LIONSGATE and MGM have been using MPEG2 and AVC.

I know that blu -ray can use MPEG 4.
but according to the link below, all the BD movies out right now are using MPEG2.

http://yellowlazers.vox.com/library/...an-bluray.html

and on high def digest: HD DVD movies are being rated as having better picture quality than BD.

can you guys name some movies that use MPEG 4?
I'm so confused.

thanks guys

Blu-ray movies use MPEG-2, AVC and VC-1.
HD DVD uses mostly VC-1, with some AVC and the rare MPEG-2.

Not true - Casino Royale uses AVC=MPEG4

You can check the movies yourself here:

^ = Casino Royale

[Scorxpion]

Latest sony releases through open season till Casino Royale Rocky Balboa and more to come

Latest releases by Buena vista like chicken little

Fox XMEN3

Are you still confused..........!!!!!and i recommend you again to visit HIGHDEFdigest and have a quick look on blu-ray Reviewed there ,you will notice how AVC has been used aggressively by most Studios

[MatrixS2000]

Oh and that url you posted made me laugh....

[Blue]

This link may be a little more helpful, however beware it's factual, I know fantasy land is more fun. I don't know what stuff they are on but I want some!!!! Second thoughts...

When the BLU-RAY format first launched all the releases was MPEG-2 with 25GB single layer discs. The link you posted has some old information. 80% of Sony Pictures new releases will offer the best picture and sound quality since they are being placed on 50GB discs and most if not all new releases will be using MPEG-4/AVC. For a short 90 minute movie with no extra’s MPEG-4/AVC and VC-1 looks good on 25GB discs also.
MPEG-4/AVC and VC-1 are being used on most new BLU-RAY releases. Formats like BLU-RAY improve over time. When DVD first came movies were single layer 4.7GB until dual layer 8.5GB discs movies came out with higher bit rates.
Both HD-DVD and BLU-RAY discs can be encoded with MPEG-2, MPEG-4/AVC, and VC-1. The advantage of some of the BLU-RAY studios is they are releasing movies on 50GB discs versus HD-DVD only has 30GB discs. BLU-RAY also supports higher bit rates then HD-DVD. So technically BLU-RAY is the better quality format for picture and sound since movies can be made with picture and sound quality that is better then the HD-DVD format can produce.

Damn, I forgot I've started to reply to this, then I got distracted PMing Goldie and Bond Girl

anyway this was moi reply:

MPEG-4 Part 10 = AVC = H.264

So anytime you see those terms it's not an MPEG-2 Blu-ray

examples of MPEG-4 (part 10) Blu-rays: X-Mn III, Open Season, Casino Royale, Chicken Little , etc

That's another important point that many people keep "forgetting"

Due to the way total bit-rate is allocated in the formats, Blu-ray can achieve up to double the video bit-rates specially in peaks, and according to a ITU test new codecs efficiency is about 2x of MPEG-2, so if you have VC-1 at 20 Mb/s on one disc and MPEG-2 at 40 Mb/s on another they'd tend to even out.

(Now, if you have VC-1 or AVC at 40 MB/s peaks that's another ball game )

[HDTV1080P]

Deciazulado,

I would love to see a Super bit movie using MPEG-4/AVC or VC1 around 40MB’s second on a 100+ inch 1080P display. The picture quality in theory would be totally awesome.

[Scorxpion]

Have a look on Rocky Balboa already have higher bit rate 40mbs posted on hometheaterspot and i already know you will be glad seeing it on big size screen.A quote from CHAD"Here's another title that only opens itself to criticism of the photography itself. Peaking above 40mbs and rarely dropping below 20"

Thanks for the info. I just read the great review. I am glad that MPEG-4/AVC is being used at bit rates above 40Mbs for BLU-RAY for some movies.

I always said MPEG-4/AVC or VC1 would look better at high bit rates compared to MPEG-2. In the professional world there is MPEG-4/AVC 4K projector technology in the works.
One day 100GB and 200GB multilayer discs for BLU-RAY will have some uses. Imagine having a entire movie at MPEG-4/AVC with bit rates between 35-40mbs for the entire movie. It would be totally awesome.

The maximum video bitrate is 40Mbps.

[Scorxpion]

You are Welcome ,ok sorry MCBAIN.another incident Thanks HDTV1080P for the valuable info

[HDTV1080P]

BLU-RAY Max bit rates

Raw data transfer 54.0 Mbit/s

Audio and Video 48.0 Mbit/s

Video only 40.0 Mbit/s
