I'm not having much luck using material produced with the
MjpegTools with DVD Studio Pro -- or any Apple product for
that matter. So I was considering sending a negative note
to Apple support, but then I recalled that there is at
least one member of this group actively using to two
software products together, so I figured this would be a
more productive avenue.
I'm using a recent CVS version of mjpegtools (I got tired
of waiting for the followon to 1.6.2) -- 10/05/2004 to be
precise. It's also a pretty recent version of DVD Studio
Pro (Academic version), version 3.0.1. But really, I haven't
had much luck with any of the Apple software reading mpeg-2
files created with the mjpegtools.
The default version of Apple Quicktime won't even recognize
mpeg-2 files at all. Fortunately, the Production Suite of tools
that I purchased with my came with an upgrade to QuickTime Pro.
Unfotunately however, while QT-Pro would recognize and read the
files, it is not able to handle them at a respectible rate --
after the first few moments of one file I created the frame
rate of displaying the video drops to between 2 and 7Hz.
Whereas a version of mplayer that I downloaded for my Powerbook
plays the file just fine.
I should say that my Powerbook is a brand new 15" w/ Super Drive",
and a 1.5GHz G4 processor. Also, the files I'm trying to play
come from two sources -- a Canopus 100 capture via dvgrab, and
using smilutils to feed into an mpeg2enc pipe and then multiplexed
with the mjpegtoosl multiplexer -- at bitrates within the DVD specs.
The other source is an IVTV capture from a Hauppauge PVR-350.
In that case, the capture was at bitrates above DVD spec, so I
use mpeg2dec to decode them, piped through pgmtoy4m, filtered,
and then reencoded with the mjpegtools mpeg2enc program, and
again mplexed. Oh, I use avidemux2 on the latter to trim the
beginning and end of the TV capture, and then save the files
as Audio and a separate Raw video stream.
I did manage to make a very simple DVD with dvdauthor from an
mpeg-2 file that went through the latter process, and it plays
on my set-top player. But I would like to make more complicated
DVD's, and take advantage of this rather expensive software that
I purchased.
Enter DVD Studio Pro. When I try to import the "asset" of one of
these multiplexed mpeg-2 video files, I get a popup that tells me:
Alert: Import Assets Could not import one file. Incompatible Format
Not a particularly informative message, much less what I was expecting
to happen -- at least Quicktime Pro can read and play the file, if
poorly.
I then tried iDVD, and it's a little more informative, but no more
successful:
Unsupported File Type: MPEG Video [in bold]
I find that an ironic statement coming from a program for producing
DVDs!
Comments, suggestions appreciated.
While I wait I'm compiling version 3.3.3 of Qt, so I can give qdvdauthor
a try. And if that doesn't work, I guess I'll be writing XML files
by hand.
Thank you very much,
Bill
