Re: problems with h264 and DVD Studio 4

problems with h264 and DVD Studio 4 (August 14, 2008 03:28AM) mark pigott
Using the methods and presets exactly listed in "Making Hi-Def DVDs on 4.7G DVD Disks"
I have ran into the following issues.

1) When taking a 24p XDCAM self-contained movie into compressor and using the HD 60 minute
h264 preset as indicated; the file comes into DVD Studio and the Asset Column (Name, Status, in Use....)
says the h264 QT is 23.98fps; which is expected. But if you look at this asset in the Inspector it says it is
29.97fps non-drop.

So there is a contradiction here.

Secondly, I try to make simple first HDDVD movie; and once the burn process gets to initiating
(h264type).mov; the entire DVD Studio crashes...

I have read tht h264 is the only way to make sure I get correct pulldown.

Could someone please assist me?!

Thanks

Thanks for the info:
I found some more reasons for what I mistook as bad pulldown; but wasn't.
a) Neither toast or DVD Studio Pro will output a DVD that is 1080p24; rather
both output this as 1080i24.

So when it hits the HD DVD Player, it wlll only output 1080i in Component mode;
which introduces all sorts of temporal artifacts that do not exist when you force the
HD DVD Player into 1080p24 via the HDMI output. The problem is that it is playing
what is interlaced footage-but the frame stutter is mitigated.

So, I am much closer to a solution. We only have to do this one HD DVD and then we are
switching to blue-ray!
