	Blue-Ray and HD DVD - Do they still use MPEG 2 or what? by Aharon Rabinowitz on Jun 27, 2006 at 9:12:40 pm Hey there- I am not up on my HD for DVD chops yet. Do the new Hi-Def DVD formats use MPEG-2 or some other video format? Thanks.

	Re: Blue-Ray and HD DVD - Do they still use MPEG 2 or what? by Ben Waggoner on Jun 28, 2006 at 1:51:27 am Both formats support all of MPEG-2, H.264, and VC-1 In practice, all the USA HD DVD titles are VC-1, and all the USA Blu-ray titles are VC-1, so far. With HD DVD, we're demonstrating transparency to the D5-HD master with VC-1. Respond to this post Return to posts index

	Re: Blue-Ray and HD DVD - Do they still use MPEG 2 or what? by Ben Waggoner on Jun 28, 2006 at 2:55:30 pm Yep, all VC-1 for the hollywood titles. VC-1 is a lot more efficient, and hence provides more consistant high quality, and leaves more room for extras. Sony's been getting reamed for the poor quality of many of their early releases. It looks like there's multiple things that they did wrong in the authoring process, but at this point this is how the formats compare in released titles: HD DVD: VC-1 compression 30 GB discs Dolby Digtal Plus audio (a few with lossless Dolby Digital TrueHD) Blu-ray: MPEG-2 compression 25 GB discs PCM (unccompressed audio) The combination of more efficient compression and more capacity with HD DVD has lead to HD DVD titles providing visually lossless compression and lots of room for extras, while the Blu-ray titles so far tend to have a lot of artifacts, and no extras.

	Re: Blue-Ray and HD DVD - Do they still use MPEG 2 or what? by vsv on Jun 28, 2006 at 3:48:43 pm What authoring tools was used for released HD-DVD titles? I've heard about Toshiba's HD-DVD authoring tool... Sonic ScenaristHD not ready for this? Ben, what you can say about Sonic CineVision and Carbon coders for encoding to VC-1 (HD-DVD compliant) or we need to wait freeware WME Studio Pro? Respond to this post Return to posts index


	Re: Blue-Ray and HD DVD - Do they still use MPEG 2 or what? by Ben Waggoner on Jun 28, 2006 at 4:01:06 pm The authoring tools used for the titles were pretty basic early tech (great quality, but not the smoothest user experience). On the commerical side, Sonic is obviously the big player with some high profile tools targeting this market. The Ulead and Apple products have been able to make discs that work in the Toshiba HD DVD player today. Microsoft is working on our Windows Media Encoder Studio Edition, which will support VC-1 elementary stream encoding for HD DVD among other things. We won't have elementary support in Beta 1, which is due to be released very soon, however. Respond to this post Return to posts index
