Compressor generates aiff file of half the mv2 file time

[stavrosh]

I am trying to make a DVD of a friend's wedding. I have received the DV segments as AVI files (compressed via DivX) which eventually after trimming and editing in QT, I transformed to mov files.
Using compressor to get the elementary streams, I have noticed that the time duration of the aiff file and the mv2 files are quite different !! Actually the aiff file appears to be half the duration of the mov or the mv2 file.
This is the first time I encounter such an oddity and I am wondering if anyone have encountered this issue and has something to suggest.
I am using DVDSP 3.02, QT 7.01 and Compressor 2.0

Thanks in advance

Could be a QT 7 issue.
*shrugs*

Go back to QT, and export the audio out by itself
as .aiff, 48khz, 16 bit.

Is the audio ok now?
Did QT give you any errors upon stripping out the audio?

Hi terryj ,
thanks for the feedback. I think that your suggestion / suspession regarding the QT 7.01 contributon to the aiff error might be valid, I have not exported the audio track , but I have used MPEGWorks 4 to get the audio stream. The audio length was equal to the video.

But now we are stuck on another issue .. the DVDSP compiler gives us a "Muxer internal error" , which I have never seen so far. Any suggestions here ?

I don't know whether this relates to the problem but QT 7 exports slightly different AIF than QT 6 did.

For this reason MPEG Streamclip doesn't currently recognize QT 7's AIF files if the user wants to mux them with the video. Maybe DVDSP has similar issues with QT 7?

Does MPEG Works 4 use Quicktime for processing?
if so, you are still in the same boat as using Compressor
with QT 7.01.

At this point would be the option to upgrade to DVDSP 4.02
or downgrade ( more preferrable) to QT 6.52.

I tried QT 7, and I had so many headaches with JUST
PLAYBACK of mpegs ( both 1 and 2), that I went back to
QT 6.52.

I will check this forum and I will google for ways to downgrade to QT 6.52 from 7.01 (and to consider that I had paid for the new version ...). If you can comment of how to do it it would be more than welcome ....

By the way this project is driving me crazy to the point that I might need to ask to get the original cassetes and re-digitize the project. The converted DivX to mov occupies 2.6 G and compressor needed 47 hours on a 2.3 G5 !!! I sense that something is wrong ... because on a 1.25 G4 similar projects were compiling in around 8-10 hours. Comments here ??

sorry about you paying for it ( more ways than one).

We are encountering a lot of problems with QT at work
and slowly but surely we are getting through them.

So far we have found that the magic combinations that
work are:

OSX 10.42/QT7.01/Compressor2/DVDStudio Pro 4.02
( with Pro Apps update)

OSX 10.39/QT 6.52/DVDStudio Pro 3.02/Compressor 1.21

anything mixed or match from these two have been
causing us headaches.

As for the new compressor, it could be ram related.
look here for issues:

also make sure you are using DIVX 5.21, other versions of DIVX
and QT 7.01 don't get along.
