Quicktime HD into HD-DVD?

[piratehunter]

Hi all,

I’ve been mastering QT trailer for DVD for a while now and I want to try and make higher quality ones. Since they have the HD trailers available, I’d like to be able to make higher quality mpeg2’s to watch on my TV. This is the process I use now:

1. Export audio in wav format and re-encode to .ace with ac3machine to DD 2.0.
2. Encode the video only in TMPGEnc to DVD (NTSC) to .m2v
3. Combine audio and video with DVDLab.
4. Burn to DVD.

This method does not allow me to keep the 5.1 audio and it makes the video 480p. I’d like to make the video at least 720p.

I’m not terribly adept at this stuff, so if anyone has some advice, please speak in layman’s terms if possible.

Thanks in advance!

If you want the video to play playable on a standalone DVD Player, then 480P (for NTSC) is the maximum the DVD Spec will support. Nothing you can do about that. Current DVD Players does not support HD.

But there is a way of doing it with ulead. you can burn as an HD DVD. anyone figured this out yet?

That would require a HD DVD player.

Which I've owned for a couple of months now.

I know how to make HD DVD's. That says nothing about how to change a quicktime HD trailer into something playable on an HD DVD machine.

convert to 1280x720 with tmpgenc or some other mpeg encoder. no templates availabe so you have to manually change to 720.

Already tried that. TMPGenc won't do a bitrate high enough. HD DVD can go to 30000.

Most use ~8Mb/s for MPeg4 AVC with HD DVD. Good for ~2.5 hrs on a DVD-9. For MPeg2 figure 16-25Mb/s with half to one third the minutes.

Encoding times are lengthy. Current AVC encoder quality is "iffy". Hardware encoders will eventually make this practical.

My copy of TMPGEnc can!

Make sure you've unlocked the template, and make sure you've set the MPEG2 Encoding Profile&Level to one of the HiDef formats (MP@HL, MP@1440, etc).

Of course, it probably helps to have QTPro, so you could export to uncompressed (watch the size!) MOV or AVI if needed.

Though you might also be able to use other, additional apps, if indeed the QT movie is compressed with the new h.264 codec (may not even need to re-encode then, just re-mux/re-wrap).

Is there a step-by-step guide to doing something like this? I have PRO but I don't wanna screw it up.

[digitalfreaknyc]

OK so i got it working with TMPGenc but my results are mixed. They look great but sometimes they're a little choppy. The video just doesn't look completely smoooth on most.

I know some of these are newbie questions but should I be encoding as non-interlaced (since the video is 1080p) or should I be doing a 3:2 pulldown? 23.976 or 29.96fps?

I've got the results almost fantastic but this is really bugging me.

What's the source material?

Remember, HD (on disc) is 720p, 1080i or possibly (later) 1080p.
These are both Square Pixels.
Both do 25(50) and 29.97(59.94). The disc version of the 1080p also does 24fps (actually 23.976).
Don't know if 720p24 is allowed or not.
Not enough info has come out about authoring for HD/BD to know if you must encode direct to 24fps and let the player add the pulldown as appropriate for the chosen output device (at playtime), or whether you encode to 29.97, or whether you encode like DVD to FAUX 29.97 by adding the pulldown flags. Sorry.
For non-industry insiders, this is still cutting edge.

"Choppiness" could be a result of too much bitrate for the system, too little bitrate for the picture complexity, you system not being up to scratch for playback, pulldown flags etc not being encoded correctly, a mismatch between the original and new framerates without correct frame blending, and on and on...

Exactly how high a bit rate do you think you need? My cable company is sending me 19000 and it looks terrific. I can't find any pixelization on it. I have some TV shows I've recorded and after editing out commercials with VideoReDo, the resulting files have bit rates around 14000 and they look good to me. I'm not sure how high a bit rate TMPGenc can do, but have you tried something around the 15000-19000 range just to see if it looks OK or are you assuming that those bit rates won't be high enough for you?

[digitalfreaknyc]

Nah. That was an old post. I got it to work properly with regards to bitrate.

I do a 2-pass VBR with a max of 25000.

Most (if not all) of the trailers are 23.976. And almost all of them are 1080p.

Was playing with this again tonight. It's almost as if a frame is dropped. any reason that would happen?
