High Definition DVD

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."

linux dvd ripping guides

[David Jao]

Since people are asking for linux dvd ripping guides, here are some ... and let's hope Judge Kaplan of the MPAA doesn't smite slashdot for these links:

1. Moritz's DVD ripping and transcoding with Linux howto
2. Linux SVCD guide, written in French
3. My own Linux Digital Fansubbing Guide (shameless plug) -- intended for anime fansubbers but perfectly serviceable as a ripping guide if you ignore the stuff about subtitles.

The summary is that all the stuff your friends do under windows (divx, vbr, two-pass encoding, pulldown flags, inverse telecine, etc.) are perfectly feasible under linux too, using free software.

Neither format is great

I have reservations about both the Blu-Ray and the proposed HD-DVD being standardized in the near future.

First, as many have stated, using a new compression algorithm with the exisitng stoage of DVDs can be both good and bad. 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.
