High Definition DVD 326
Vinnie_333 writes "Looks like the specs for HD-DVD are currently being discussed by Hollywood big wigs, with an optimistic product release date of Xmas of 2003. Unfortunately, they seem to be completely disregarding the higher storage capacity of the Blu-Ray disc standard, that will hold 6 times the amount of a DVD-9, for the current red laser format with a different compression algorithm. Come on, more storage is always a good thing. Not only will it give us the quality we deserve, it is likely to cut down on Hollywood's largest fear (piracy) by making the media ungodly HUGE."

Video encoding isn't an I/O-bound process, however. On a 1.0-GHz Athlon with DDR memory, encoding ~45 minutes of film-rate NTSC video with TMPGEnc to a form suitable for SVCD mastering takes about 11 hours with the quality settings I use (10-bit DC-component precision, highest-quality motion search, 2-pass VBR, etc.) About the only part of the process that might be I/O-bound is resampling and normalizing audio, and that takes just a few minutes. Inverse telecine, while faster than MPEG-2 encoding, also is mostly CPU-bound. If you could pipe from the DVD-ROM drive to the editor to the encoder, you'd see minimal improvement (if any) in encoding time. In fact, I suspect it would actually be slower.
(This doesn't even take into consideration that most of my encoding is of video from my TiVo, and that I need both inverse telecine and nonlinear editing capabilities to prepare a recorded TV show for archiving to SVCD. NLE is handled by Avisynth working on frameserved MPEG video from the TiVo, but inverse telecine is done by VirtualDub. You can't frameserve from VirtualDub if you want it to do inverse telecine...the output will still be 29.97 fps instead of the desired 23.976 fps.)

Firstly when you "rip" a dvd you get a whole bunch of files. Some are the movie, some are the menus, some are the specials, info files etc... So you really need to rip 4 or 5 seperate (but combined by the encoder, not the ripper) movie files (max size 1GB) then encode on those files.
Next (I'm just talking about pal here not ntsc, i believe you may need to do more for ntsc) you need to crop and resize the picture, cropping is neccessary because of the black bars at the bottom of the screen, they take up a lot of bandwidth believe it or not. Also I like to chop a bit of each edge to give it a 640 horizontal res. The cropping process is usually a manual and visual one which is not well suited to the command line. You also need to rip and encode the audio. It's stored in AC3 format in the same files as the video, I like to process the audio seperatly from the video, obviously this requires me to have previously ripped the files. You then need to combine the audio and video and you may wish to rip the subtitles.
Subtitles are stored as pictures (!) on the dvd not text, for reasons of filesize you will probably want to convert them to text though. This is an interactive process using OCR (like scanner software) but you have to sit there and type letters into the OCR software. The subtitles also come from the same files as the audio and video so again using pipes is not a particularly viable option.

The problem with the red-laser DVD is that it is already pushed to its limits to hold ordinary encoded PAL/NTSC video data plus the new high-data-rate audio (DTS and/or DD), and even then critical viewers mutter about compression artefacts. HD TV displays are, to make them sellable to Joe Public, going to require about four times as many pixels on screen as ordinary PAL/NTSC. Compressing HDTV harder is going to result in a display which is pretty well identical to existing DVD playback, rather negating the point of shelling out the bucks for a new receiver/display unit.
If they want four times as many pixels on screen, the designers are going to have to use a record media with a higher data transfer rate; they can't get that from DVDs except by perhaps spinning them at four times their rated speed, and that only works for 44 minute TV episodes. If they want to sell two-hour long movies without having to do the laserdic thang of flipping and changing discs every hour or so, they'll need the blue laser.
Blu-Ray (tm) is backwards-compatible. It'll play anything that comes in a 12cm optical disc -- CD, CD/G, DVD, SVCD, maybe even DVD-Audio, but HDTV replay is the reason it was designed in the first place.

Again, just for the record, 1080i--including a Dolby Digital audio track-- compressed to about 20 Mbps is acceptable. (OTA HD is encoded at slightly over 19 Mbps and it's usually very good, while D-VHS at 25 Mbps is exceptional.)

The purpose of region encoding was to allow them to sell the same movie at different prices in different markets and also to control their "marketing strategy". They'd want to do this for a number of reasons:
1. Different economies: The ideal price of a DVD (that at which the makers make the most money i.e. where price x #sold is maximized) is very different in France than in Japan. In order to maximize their revenues, the producers want to price them differently. Now, they don't want people buying the DVDs at the cheaper markets and selling them at the other markets because that negates the whole thing.
2. Distribution rights: Typically distribution rights to a movie are sold to a local distributor who then makes all the money off of it. If people are able to buy the same movie in Region A and import it in to Region B (they'd want to do this because of cost and availability), the distributor for Region A loses to the benefit of the distributor in Region B. They wanted to prevent that happening.
3. Marketing: Movies are (used to be more in the past) released at different times in different markets for various reasons (translations, legal, lazy asses, etc.). This is accompanied with advertising campaigns, star appearances, etc. They didn't want to undercut that by making DVDs from other regions available via import and mainly because they liked being in full control of distribution.
For all those reasons, region encoding seemed like a great idea to them.

It is definitely good studios, who already have the standard DVD mastering equipment, and for DVD player manufacturers, who have already developed the red-laser hardware. It is good for the consumer in that the new players would probably be pretty cheap. I think cheapness is key for the acceptance of HDTV technology. Currently the sets are very expensive, and with the limited number of HD broadcasts, there is little incentive to buy one. Of course supply and demand is at work here--if more people bought them, the price would go down. Therefore, affordable HD-DVD players would go a long way in making HDTV's more attractive and useful, which would make their price drop and increase their market presence. Hopefully we would then see more HD broadcasts.
The problem with using exisiting DVD storage for HD-DVD is that is probably going to be obsolete sooner... bad for the consumer. Plus, I question how good the new compression algorithms really are. HDTV will tend to make compression artifacts and defects all the more obvious... again bad for the consumer.
Blu-Ray has many benefits in that has a much higher capacity (100GB if I remember correctly), so it will probably have a longer lifetime in the consumer marketplace. And, the picture quality would undoubtedly be of higher quality because the compression ratios would be lower. However, I fear that it is too costly of a technology to be a standard today or the next year. It would be great 5 years down the road, but not now. My reasoning? Blue lasers are really not ready for prime time... They are difficult to manufacture and are still extremely expensive. DVD player manufacturers still probably have much work to do to develop a consumer-grade blue laser disc playing system. Furthermore, the disc manufacturers would have to completely retool. I can see the discs and players being very expensive for a long time. This could further delay HDTV's acceptance in the mass market.
If I had to pick a technology today, it would have to be Hollywood's HD-DVD format, because I think it is important to give consumers incentive to buy HDTV's. Unless the Blu-Ray format can be substantially cheapened in one year (unlikely), I say wait a few more years for Blu-Ray.

Like DVD, expect it to be extremely difficult to author a properly formatted and encrypted HD DVD (not ripped from an existing one)...

BTW I worded my original post very carefully. I know lots of independent producers are making great films with cheap digital equipment (eg DV) - you're just not able to see them in major theatres (yet), and they have quite an uphill battle to obtain marketing dollars and distribution outlets...
I also know it's possible to author simple DVDs with e.g. Apple's iDVD, but those won't have studio-level features like a Dolby Digital soundtrack, a full menu system, etc... Both of which can be had for a modest ($2K-$10K) investment in software, but good luck trying to produce a CSS-scrambled, region-locked DVD (which distributors might demand) on your own =).

I know some people over on avsforum.com who did exactly that, except they used DiVX which is almost the same as MPEG4. The results were fantastic. For the most part it was not possible to distinguish between the original and the DiVX. With a commercial MPEG4 I am sure the results will be even better.
Other then brand-new copy-prevention schemes, and the whole having to buy it again thing, I look forward to Hi-Def DVDs.
If they are smart, they will also add anamorphic 2.35:1 and pan&scan tracks so that dumb people can buy the same discs as smart people and still be happy. (Yes, I know those two are part of the current DVD standard, but they aren't common enough in players for any publisher to use them.) And, if they are really smart, they will do double-sided discs - one side regular DVD and one side Hi-Def DVD. But when as the MPAA ever been smart?
Red Ray vs. Blue Ray (Score:3, Insightful)
Backwards compatibility.
The only way they can entice people to buy a new HD DVD player, is if it can play their old SD DVD's as well.
Now, of course one could conceivably build a player with both red and blue ray lenses, but sticking with red-ray only means manufacturing the players will be cheaper.
Cheaper players means faster implementation in the market place.
Don't forget, it's all about the Benjamins...

Damn, it'll still take nearly 20 of the things to store a 2 hour, 720p movie in uncompressed form.
Heck, that (30 GB) is a little less than 2.5 hours of standard DV video. (DV doesn't use inter-frame compression, it's more like motion-JPEG rather than MPEG, to give clean frame boundaries for edits.)

4) Even when rewritable Blu-Ray comes out, the media probably won't have nearly as many rewrite cyles as you would need to make a hard disk out of it, unless you want to replace it once a week. In fact, the use of a high-refresh rate application like virtual memory would make the disk overheat and fail very quickly.

Why multiple lasers? (Score:2, Interesting)
Current-model DVD players use their 650nm lasers to play CD-Rs which are written using 780nm lasers with no problem. It can't work the other way around -- a 780nm laser is too crude to accurately decode a DVD track, but there's no reason why a 405nm Blu-Ray laser shouldn't track and read a regular DVD or a CD. One caveat is that CDs and DVDs are made in such a way that in their native pressed media, the depth of the pits is 1/4 the wavelength of the light normally used. This allows the laser optics to use an interference effect to enhance the signal; typically a pit in a pressed CD produces a 90% swing in the signal voltage from the optical detector. On a modern CD-R that drops to 30% as there is no pit involved, just a discoloured area of dye (CD-R/Ws are worse, at anything down to 14%).
First-gen Blu-Ray layers will play Blu-Ray pressed discs perfectly, DVD and CD pressed discs very well, DVD-Rs and CD-Rs not so well and rewriteable CD and DVD discs will be problematic. The next gen players will be better, just as modern DVD players don't have a problem with CD-R/W VCDs unlike the early days.

Studios don't like movies which run much over two hours, since they get less showings in an evening at the theatre. Fewer showings means fewer seats, which means fewer paying customers, which means less profits for the industry.
That's at least part of the reason that Terry Gilliam's masterpiece "Brazil" was show for many years in many cinemas as the 90-odd minute "studio" cut, whilst Gilliam's edit (the "Director's cut" I guess) is more like 140 minutes. Gilliam's version is, IM(NS)HO, is by far the superior version of the movie. (OK, it's more complex that that - there's Gilliam's "European" version at 140-ish minutes, his US version at about 130 and the "Studio" version at 90ish. This is far more information than you will ever need, and I apologise now for the fact that I am rambling on in an almost completly off-topic direction about one of my favourite movies. Sorry
