If they get VC-1 encoded titles on 50gb discs, Blu-ray actually has me excited again.

Hopefully when Fox announces their titles next week, they'll be VC-1 encoded as well.]]>Aug 25th 2006 11:21AMhttp://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/http://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/Aug 25th 2006 11:25AMhttp://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/http://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/Aug 25th 2006 11:36AMhttp://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/http://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/That's still not good enough.

Banish the Microsoft codec [VC-1] and give us the highest quality codec, H.264 MPEG4 AVC.

Thank you.

My understanding is that a dual-layer HD-DVD-RW can have 50 GB capacity; existing players should be able to play these. The capacity of prestamped HD-DVD disks is limited by the manufacturing process.

If HD-DVD catches on, could they improve the manufacturing process to make a disk that looks like a 50 GB disk to the player? This transition might be as or more difficult as the transition to manufacture Blu-Ray disks, but it would be easier to justify to support a format that already has commercial success.

Toshiba also has demoed a 45 GB triple-layer HD-DVD disk. It may be tough to manufacture, but, again, it's much safter to make an investment in a commercially viable format than one with an uncertain future.]]>Sep 1st 2006 7:45AMhttp://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/http://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/
How much disk space does a 2hr movie take up when using each of the codecs?

Maybe the Blu-ray camp will have space for special features on their 25Gb disks!

Better yet guys, move to 50Gb disks and give us loads of nice high def extras!]]>Aug 25th 2006 12:22PMhttp://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/http://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/Aug 25th 2006 1:37PMhttp://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/http://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/
Suppose we encode a 2-hour movie at 1080p/24fps using VC-1 and/or H.264, but with two different sets of restrictions: (1) we are restricted to the maximum data transfer rate, and total storage capacity, of 2-layer HD-DVD; (2) we are restricted to the max. data transfer rate, and total storage capacity, of 2-layer BD (let's assume equal "typical" audio tracks for the two cases).

Given this, will there be a visible difference in PQ between the two, if we use a very high-quality 1080p display device and sit at a distance of, say, four times the screen height?

Or here's another way to put the question: for a 2-hour movie at 24fps, what's the minimum data transfer rate and storage capacity you need to achieve no visible difference in PQ vs. that from the studio digital master (using the set-up described above) -- and how does this rate and capacity compare to what can be offered by either BD or HD-DVD?]]>Aug 25th 2006 2:47PMhttp://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/http://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/Aug 26th 2006 6:34PMhttp://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/http://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/
Both the Toshiba and the Samsung have the SAME broadcom video decoder....]]>Aug 27th 2006 9:47PMhttp://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/http://hd.engadget.com/2006/08/25/warner-blu-ray-releases-may-switch-to-vc-1-codec-soon/
The best option is to use a lossless codec, such as H.264 High Profile.
