DVD Rendering an HD dvd?

[Greg Barringer]

Do you mean burning Blu Ray to a 4.7gb DVD?
As you know HD DVD was discontinued in favor of Blu Ray (BD)

[Don Cobble]

No just wanting to make the best wide screen dvd possible – NON blue ray.
but didnt understand if there is an HD dvd that is still in HD when DVD arch is done with it?

I think that you are mixing your metaphors. There is only one flavor of HD – Blu-Ray.

You can put about 12-minutes of Blu-Ray (.m2t or .avc, I think) on a 4.7Gb DVD, but it only plays in some Blu-Ray players (and NO DVD players).

That is my question? there is no such thing as an HD format dvd besides a blueray? Even if your project is rendered out in an HD format M2t when DVD arch gets done with it, it is SD wide screen? Yes?
and yes my terminology may be off.

There is no way for a DVD that is playable on a DVD player to be HD. DVD’s were invented almost 20 years ago in 1993 long before HD became commercially available.

If you want HD you’ll need a Blu-ray player or HD media server. If you want to make DVD’s that play on DVD players then the best you can do is SD Widescreen which will look nothing like HD because it will have 5x less resolution but should still look better than footage shot with an SD camera.

You pretty much need a Blu-ray player to play any HD video on a disc. With that said, it’s nearly universal for Blu-ray players to play an HD format on DVDs.

Unfortunately, the format they play isn’t precisely Blu-ray. DVD Architect can create a Blu-ray formatted DVD, which will play in virtually no Blu-ray players. But they nearly all play the AVCHD format, largely for camcorder support. AVCHD was of course derived from Blu-ray, but it’s not identical. A correctly formatted AVCHD disc must have audio and video at 18Mb/s or less, and a few other small details.

There’s a freeware tool called multiAVCHD that can prepare such discs from projects rendered to compatible video from Vegas.

“DVD Architect can create a Blu-ray formatted DVD, which will play in virtually no Blu-ray players. “

Whoah, back up a sec, so my new blu ray burner makes discs with DVDA that don’t work? So I need a new authoring burnings software?

No, that’s not what Dave said. Let’s define what we’re talking about here first because DVD is used in two different ways in this conversation: Way (1) DVD is a format. It contains a VIDEO_TS folder and VOB files. Way (2) DVD is a shiny plastic disc media that you can store information on including data files.

What Dave is saying is that you can use DVD the shiny disc media to store Blu-ray formated data instead of DVD formatted data. At this point it’s not a DVD format anymore. It’s Blu-ray format on DVD media. That makes it a hybrid.

The problem is that DVD media was designed to hold a maximum of 9Mbps data read by a RED laser. When you place 16Mbps video on it and read it with a BLUE laser (that Blu-ray players have) they don’t always play. My Samsung Blu-ray player will play a few minutes of a DVD formatted for Blu-ray and then it starts stuttering to the point that you can’t watch it anymore. The Playstation 3 will play the same disc fine but sees it as a data disc.

So all Dave was saying is that you can format a piece of DVD media with the Blu-ray format, but it’s not guaranteed to play. This has nothing to do with DVD Architect. In fact, DVD Architect has no idea that you stuck a piece of DVD in the burner instead of a piece of Blu-ray in the burner. It’s all shiny round media to DVD Architect.

Yeah… thanks for clarifying. Let me translate Davespeak a bit… when I say “DVD” unqualified, I’m likely referring to the ~5″ round shiny thing. There are any number of possible formats for a DVD… the one everyone thinks of is DVD-Video, that of the VIDEO_TS and EMPTY AUDIO_TS folder. Of course, there’s also the officially sanctioned DVD-Audio format, which will have lots of stuff in the AUDIO_TS folder. And a few other “standard” formats not officially part of the DVD Forum list of specs, such as Microsoft’s WMV/HD format (an early HD format… I used to have a red laser DVD player that actually did recognize and play this format… HD-Net released a few videos on this format), or AVCHD on DVD. A DVD is just data… all of these “formats” are just a standard for how that data is organized.

And my basic point: the Blu-ray format can put on DVD by DVD Architect. This works great in PCs with Blu-ray player software, but will not play on the majority of Blu-ray players (and it will not play on any DVD player). Blu-ray on a BD-R, which is really the expected output from DVD Architect in Blu-ray mode, should play on most Blu-ray players. As will the AVCHD format, on a DVD disc.

Blu-ray players actually have blue (well, blue-violet, 405nms), red (650nm), and probably infrared (780nm) lasers. Sure, it’s not required by the spec, any more than DVD players were required to support the IR laser for CDs.

Technically speaking, the blue laser could do it all.. at least as far as glass mastered discs go. But once you get to CD-R/RW or DVD+/-R/RW, the blue laser is no good. The organic dyes used for the “R” discs, in particular, is very frequency sensitive. Some early DVD players left out the IR laser, and got lots of flack. I don’t know of any Blu-ray player that made this same mistake, relative to DVD or CD.

The issue is logical format. The player has a bit of software logic… here’s a Blu-ray disc, launch this player software, that kind of thing. For whatever reasons, many (not sure about most) players will not play a proper Blu-ray format from DVD. It may simply be that there’s only a guaranteed 2x DVD speed in most Blu-ray players, which is not enough to fully support the Blu-ray format, so they just don’t bother. But nearly every Blu-ray player will play the related AVCHD format from DVD. Why? Could be that AVCHD actually is a formally defined DVD format (eg, part of the AVCHD specs for camcorders), whereas true Blu-ray-on-DVD is not.
