An HD movie fits on 8.4gb

[mercanucaribe]

I'm sure we know by now that a 1280x720 (maybe even 1920x1080) compressed with H264 will fit into 8.4gb, which is the size of a dual layer DVD! They look good with that compression too-- better than what Time Warner Cable pipes out, what with no interlacing and overcompression. What a world we live in... How is this possible, and could such techmologies allow higher resolution HD content to be fit on existing HD-DVD and Blu-Ray discs?

Maybe but remember all the extra crap they like to stick on DVD's. Also, DVD players don't decode H264 do they?

 

[Chadder007]

Plus they have triple layer DVD technology now too...

What compression is being used for audio, I thought one of the drawls for Blu/HD was it had the space to have uncompressed audio. Personally, I would wish they would start putting tv shows on fewer discs (sopranos could be on 1 blu-ray, instead of 4 dvds).

T2 and Standing in the Shadows of Motown were released almost 3 years ago as 720p WMV-HD on red laser DVD (dual layer DVD-ROM). SitSoM was encoded at around 8100kbps (they panned it in one of my video mags). DVDs are 4000-8500kbps (Variable usually for DVD-ROM)

With VC-1 you can do 1080P on a single layer dvd with pretty decent audio (640Kb 5.1 in the advanced profile of windows media) and get amazing results...a DVD-9 can hold something along the order of 3.5 hours of VC-1 encoded HD material

wohoo. i have a question is VC-1 some sort of H264 codec or is it something entirly different.

 

[nismotigerwvu]

Its more of a competitor to H264...its Microsoft's HD codec...bluray and HDDVD both support it..check out its wikipedia entry for way more info than i can could tell you

VC-1 is based on the Windows Media 9 codec and is an evolution of the designs found in H.261/3.

VC-1 is more or less the alternative option to H.264 or also known as AVC

If by "fit", you mean "compress the hell out of", then yes, you can use more better compression to "fit" HD movies onto standard DVD media.

Note that Blu-Ray and HD-DVD use AVC, which AFAIK has similar compression to H.264/MPEG4. Most broadcast HD is MPEG2. If you want to put three hours of video on a dual-layer DVD, you get about 6Mbps. H.264/AVC are good, but you're looking at serious degradation of image quality if you want 1080p video at that bitrate. Even 1080i or 720p are going to be noticeably worse than if you have 15-20Mbps to work with.

 

[michal1980]

yes even more overall compressed hd. heck you can probably fit the movie into a cd using only 700mb of data.

hd-dvd caps at what? 25-30mps? and blu-ray is up to like 40mps?

so ya you can go down to 6mps is you want, just throw out roughly 6x more data.

and you have to remeber even at the 25mps the data is already compressed 100's of times from the orignal image

 

[hans030390]

I'd rather have as little compression as possible. Besides, once even better, bigger tvs come out, the compression will be even more noticeable.

Or that space could be used for extras...which so far is lacking on Blu-Ray.

True HD on DVDs is pretty impractical, I think.

Pirates came with a WMV-HD DVD.

Watch the HD movies of Xbox Live Marketplace.

The films are around 6gb, including audio, and authored using VC-1 at 720p. The quality is amazing and does not suffer from the macroblocking/banding mess of broadcast HD.

For a lot of people, the HD quality off Marketplace is good enough HD and this is coming from someone with 50+ HD DVD/BR movies

 

[jtvang125]

On a few 720p videos encoded with x.264 at about 8gb file size I can still see slight macroblock/banding in the dark scenes on my 50" hdtv.

You have to remember that even the video on a hd-dvd or blu-ray is still slightly compressed. These heavily compressed hd movies still look good because of the more efficient codec being used now and also there's just so much data to begin with.

 

[nismotigerwvu]

those insanely high bitrates are more filling up the discs than getting real use....go hover at avs forums and you'll see what kind og progress is being made with VC-1 profiles and how overrated H264 really is...and forget about mpegII at any resolution beyond 480P (heck even at it) its simply decade old technology and was a bandaid at best

So did T2: Xtreme Edition. Looks quite good to, at 1080p, though the bit rate is lower than HD-DVD and you can see banding and artifacting here and there on an LCD.

Too bad I've only been able to play it once, because it also has some of the most foul, draconian DRM I've seen in my life...it checks your IP to find out your geographical position, and if you are outside of the US, it won't play, even if you have a legit copy. :disgust:

I used to be able to use a proxy to bypass this, but not anymore for some reason.(the authentication expires after a week)
