HD-DVD Capacity...

Anyone! :)


Off the top of your heads how many Gb does a typical Hollywood Blockbuster movie take up on a HD-DVD disc with all the best audio included? And are the extras on any of the new HD-DVD movies in HD or just your typical SD. :rolleyes:


Thanks

Studios will add HD extras to a release when they deem it worth the effort from a marketing perspective. You're more likely to see HD extras with blockbuster new releases, though there's some killer HD extras on the HD-DVD of Robin Hood.

So if the total capacity of a HD-DVD is 30 GB for a dual layer disc then that means there's not that much space left for more HD content unless the other side of the disc is used for the extra.

the more important question is, who cares about extras? :D

I'm not a fan of extras but I'll give you those. Both are an example of extras done right (never mind my huge fan obsession with all things LOTR).

What will probably happen is the same thing that happens today. The movie will be available on one disc "basic" format with a two disc "Collectors" or "Deluxe" addition available for extra $$.


The technology exists for them to do 30/9 combo discs and put the extras in HD on the 9GB side, but it sounds like the studios would prefer creating a second disc (even if it is an HD-9 disc) because "two disc special edition" is a good marketing bullet point.

Excellent point! Why did that not cross my mind??? :rolleyes: Offer two disc DVD and keep everything in HD. This will probable be the answer for 50GB Blue-ray. I've long enjoyed buying two disc DVD. It makes me feel as if I was getting more for my money. :D

Troy is one of the best examples of picture quality, has a full compliment of extras, In Movie Experience, Dolby True HD sound track, and clocks in 18 minutes short of 3 hours.

It is written that a 15 Gb HD-DVD can hold 4 hours of HD information and the 30 Gd single side can hold 8 hours of HD data. It's not as high as what Blu-ray can deliver but seem to me there is still plenty of space available to hold a typical 2 hours Hollywood blockbuster movie and still have room for some extras in HD to spare on the single side 15 Gb disc.

there is no size. There are WAY too many variables. Except for the video, there is Audio (lossless/lossy, 16/48 or 24/96) one track or more, PiP, IME......


8ohms: 4h is not realistic on a 15GB disk. That would be an average of 8mbps for everything ( interactive stuff, audio.....) for example Dolby sais the average for a 5.1 24/48 DTHD is 3-4 mbps. Imagine what that would mean for a movie.

Umm, I believe Batman Begins has an average bit rate of only 9mbps or so and is the HD-DVD reference disc now.


Remember, VC1 codec will continue to improve and evolve, 30GB might seem like copious space in very short order, and if it's not as others have indicated consumers have already demonstrated they will go for the 2 disc special edition with the feature on one disc and extras on another.


HD features will start to appear on discs when customers demand it, HDTV becomes the norm and studios feel like getting early adopters (like us) to double dip for early release titles.

There are titles where we could do 4 hours on 15 GB. A lot of HD broadcast is show and posted with HDCAM (internally 1440x wide) with stereo audio. Doing that in 8 Mbps total isn't unreasonable.


I did a 8.5 Mbps MPEG-2 feature last summer, and it wasn't transparent, but it was still pallpark decent, and it wasn't VC-1. I could definitley have done the same title at 8 Mbps average with VC-1 and had it pretty darn good.

Although I haven't seen BB on HD-DVD, I have no doubt it's a fantastic looking disc. Even the SD version is sweet looking. Warner will most likely release it on BD50 for Blu-Ray. It will be interesting to see if they use a higher bitrate VC-1 for the BD-50 since they have so much more room to play with, and how it will differ (if at all) from the HD DVD. Interesting times ahead.

You are incredibly wrong. It's almost impossible that Warner would spend the same money they just spent on doing the BB transfer to redo it for BD50. Especially when in all likelihood the benefits would be minor (if any).


Any studio that spends the money to do a quality VC1 transfer as painstaking as BB is going to release it to BD without redoing the feature. If anything they release it on BD25 and cut some of the special features like TrueHD and IME.


The nice thing that the BB transfer proves is that you don't need high capacity to deliver phenomenal HD-DVD experience. HD-DVD 30GB does it very nicely even for a really long feature like Troy.

UnLikely they they will go the BD50 route. They seem to have only been using the BD50 for the Day and Date Superman, as away of using the promised BD50 allotment the fact is the HD-DVD version has more features. I really think they want a BD50 movie out and since its a Combo on HD-DVD and its day and date they can use a higher price on the BD50 unit then their other BDs to cover the increased cost of releasing a BD50.


You have to remeber Warner is a Primary HD-DVD supporter, and they won't be making a cut that they can't use in HD-DVD. Extras are the real sticking point. If 25GB is to small they will cut them out, if 30GB is to small they will cut them out. But chances are if they are going to use BD50 and it won't all fit on 30GB they will probably package a Single layer second disc, which combined might still be cheaper for them then a single BD50.

It is amazing how some of these numbers migrate. I believe it is between 12 and 13Mbps average (12.6Mbps is the last number I remember reading) and 19Mbps peak for the video, with the total for everything reaching the 30Mbps max mux rate, or very close to that.

not how much a B&W silent movie will need :) we are looking at the next generation movies, not stereo and reduced screen. Next thing you will show how 4h of SD can fit on a 15GB disk
