Is it possible to make a HD and SD DVD?

[Jim Watt]

We’ve had excellent luck authoring HD DVD’s in DVDSP using a 720P master and the H264 codec in compressor. We get an hour program on a DVD 5 with enough room left over for a motion menu at the beginning. We’re doing them for distribution, replicating in a 7 burner tower.

This tower is not hooked up to a computer. Our Rimage, that is hooked up to a PC won’t recognize the master.

Quality is awesome and I agree with Walter once you burn Hd or Blu Ray DVD’s you don’t want to go back.

Hey Jim,

Thanks for the response. DVDSP is a little out of the question for now given the state of HD DVD as a format (not to mention it doesn’t support the final spec.)

When I said replicate I meant the glass master version as opposed to burning in quantity. If you don’t mind sharing, what kinds of projects / markets are you distributing these discs for? I would be so nervous about selling something that should* work in someone’s player.

The three titles we’ve produced, we market on our own website. “Discoveries…America Music, Sunrise/Sunset”, “Discoveries…America Music, New England” and “Discoveries…Argentina, Patagonia”. We’ve sold several hundred and have had no complaints.

Not sure what you mean that the discs produced in DVDSP don’t “meet the spec”. they work, they’re HD and they play as HD in HD DVD decks. We also sell several thousand duplicated SD DVD ‘s each year and also have no returns from them either. Of course we also sell 10’s of thousands of replicated DVD’s from DVDR masters too, but seldom get any of them back either.

Basically if it looks like a duck, quacks, swims and flys like a duck…is it a duck or a ???

the build engine in DVD Studio Pro doesn’t conform to the final specs used in hollywood produced HD-DVD discs, but like you said its a moot point, because they do playback and work fine on existing players.

I’m wondering how you are able to fit an hour of 720P on a DVD-R and keeping up the quality.

You are undoubtedly using pcm (.aiff) audio since dolby isn’t supported.

What frame rate and bitrate are you using for h.264?

[Jim Watt]

I’m using surround sound AC3 and the default bitrate in DVDSP for H264 HD DVD.

It seems that Apple has been silently improving on this in recent updates. Or is it the players that are getting better with every update? HD-DVD (just like Blu-Ray) is a moving target

[jim Watt] “I’m using surround sound AC3”

you do a 5.1 AC-3 and you get sound output eh?

2.0 stereo doesn’t seem to work. An HD-A1 will be silent,
so I used pcm (godawful waste of disc space) up to this
point.

I’ll have to try that out.

Thanks!

I have the same player. The Samsung website has firmware updates that turn this feature on. My BD-P1400 now plays BD-R and BD-RE discs.
