HD/SD Question

[BillyHoyle]

I printed a quicktime file to both SD and HD and then burned in DVD Studio Pro in SD and HD. Both of the DVDs play in my computer (imac), but in a few SD DVD players I tried them in, neither one plays. Does HDV have to have to be burned on an HD DVD, or played in an HD DVD player? And why wouldn't the SD version play?

HD cannot be burned on to a regular DVD. It must used an HD media such as Blu-Ray or HD-DVD and played on a compatible player. Burning HD on a DVD simply down-convert it to SD. I'm not sure why the SD DVD wouldn't work though.

Incorrect. HD, and more specifically HDV can be burned in HD with a simple DVD-R and a standard burner. Playback can be sketchy unless you have a fast DVD burner. (my 16x USB works nicely)

I have a Toshiba HD-DVD player and have made lots of HD-DVD's from inexpensive DVD-R media. They play in full 1080 without a hitch.

Elton. What software did you use?

DVDSP4. It has a MPEG2 1080i HD-DVD setting that will burn to standard DVD's.

If you're a PAL HDV user, things get even better: You can export HDV 25F or 1080i (or a mixture of the two on a 1080i HDV timeline) as a self-contained QT movie and burn to HD-DVD *without recompression*. No time wasted transcoding because the HDV is GOP-compatible with the MPEG2 HD-DVD spec. All DVDSP4 has to do is mux the audio, which is a very quick process. The computer will then burn 25 mbs HDV formatted as a HD-DVD volume.

30F and 1080 60i work the same way, but unfortunately 24F is another story. It has a different GOP sequence and needs to be converted to a 15 GOP structure to play out correctly as a HD-DVD. I don't know of any method of burning 24p HD-DVD's that's similar to a 24p SD-DVD.

What's really cool is the fact that I can burn HDV to HD-DVD much faster than downconverting to SD and burning anamorphic SD DVD's.
