  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

right.. good find
 
I personally think one of the reasons for slow HD adoption was it just wasn't good enough. We here are the lucky ones as we've probably edited some uncompressed HD footage, or seen footage straight off a pretty good HD camera, or coloured a 2k DI of some 35mm footage expertly telecined. But the viewers haven't. They're not seen what HD, or even SD for that matter, is capable of. A DVD is probably the best SD picture most viewers have ever seen.

4k, delivered direct, not broadcast, would be the equivalent to a home IMAX cinema for the average viewer. The difference would be noticible, and stunning, and they'd see the benefit. Home cinema would, finally be, cinema quality. It's a nice dream, and it's nice to share that dream with my fellow dreamers.

I wonder why the studios aren't releasing the titles in a high enough bitrate to fill the entire 50GB disc?

I'm not really sure I know the answer to that one either, but I think a lot has to do with the codecs themselves. As the bitrate for VC-1 and H.264 increases, the gains in quality are minimal past a certain point. That combined with the current state of affairs with the format war and whatnot may have something to do with it. Since both HD-DVD and BluRay use the same codecs and can play back the same video files (only use different menu systems -- BD JAVA vs. XML), studios may also be catering to lesser standards to facilitate future transfer to either format with minimal effort. A 50GB BluRay disc has enough capacity to deliver a 2 hour feature at full bitrate and still leave 250MB for meunus and ROM features. Bitrate allowable for a 2 hour feature obviously must be sacrificed as they begin to put on other things like deleted scenes or outtakes, or other bonus content.

But if they're also making sure they can jump over to HD-DVD in a pinch with minimal effort, then suddenly they have 20GB less space to work with on a disc. Considering the actual usable space and if the same 250MB is reserved for bonus content and menus, that leaves roughly 28,000MB. Filling that entire space with a 2 hour feature would still allow for a 31Mbps data rate, which I have yet to see on any BluRay or HD-DVD disc. Hmmm...

...I'm kinda stumped.
 
Same thing happened in the beginning (and I guess "end" of) DVD. Not all the players probably support the higher/maximum bitrates yet (it takes a lot out of drives and decode power [usually the higher the bitrate the more intensive to decode]).

There might be other reasons like familiarity with the encoders and best cases for the encoders and so on.

I have plenty of DVD's in my possession that do not fully utilize the 9 GB available. Heck, I have a couple of single layer ("full" length) features.

Also, depending on the length of the movie, number of (and type) audio channels, subtitles and other features it might be using the maximum alloted bandwidth but not fill the disc. That can happen for DVD, especially if the movie is not that long.
 
I sit at home most nights and watch films on my 720p native dlp projector, quality looks just as good as the DLP in theaters. DVD resolution sucks.
 
Yesterday I demo'd a brand new, sub-$4K Panasonic 1080p LCD projector that was just flat-out stunning. Watched some good HD DVD and BluRay
clips on it. (King Kong, Superman Returns, etc.)

The quality from this easily surpasses traditional film projection in the cinema, but it depends on screen size to be of utmost benefit.

I project 720p onto a 12 ft 16x9 DIY screen at home, and view about 18 ft. back.

I am simply jonesin' for the 1080 however. The extra detail is noticeable.
 
The only reason I go to the movies is to get 2 hours of peace from my demanding family.....otherwise I would never put up with the kicks to the back of my chair and $12 popcorn.
 
I think the first 4K adopters might be high-end PC gamers/video editors. Right now Dell and Apple having something like "2K+" flatscreen LCDs, around 2560 x 1600. Soon that number will increase. We could probably see 4K LCDs for computers within 5 years. Imagine playing a first-person PC shooter at 4K on a 30" display! Whoa.
