Problem Bouncing To QuickTime Movie in Stereo

[Grantica]

Hi
I'm new the forum. just got PT7.2 and think I found a problem. When I try to bounce to a quicktime movie in stereo as a stereo interleaved it seems to bounce as a mono sumed file.
anyone come across this? Help.

Yes, I've noticed this today too. On several systems running both 7.1cs10, and 7.3.

I also saw some issues earlier today with a client where the quicktime in pro tools was perfectly in synch, but the Bounce to disc was clearly out of synch and got worse as time went on. Which means it was bounced at a frame rate not consistent with the session settings.

What's going on here with Quicktime!

Yes, this has plagued us since we upgraded from v6.4.1cs4. It happens in v7.1cs8 and v7.2 and v7.2cs1. I haven't tried v7.2cs2 or later. The workaround, if you have QuickTime Pro, is to bounce out the audio to be the exact length of the QuickTime movie. Then open the bounced audio and the movie file with QuickTime. Next, Apple+J the movie and delete the sound track. Then go to the bounced audio file, select all, and copy. Then go to the movie, select all, and add scaled. Save that as a self contained movie, and you have married your picture with your audio. It would be nice if we did not have to go through the workaround I just described.

Be very careful when using ADD SCALED. You are very likely to stretch the audiotrack to a new length, thus creating a different sync problem. Use ADD instead, that will work even if your movie and audio are different lengths, as long as they have the same start (paste) point.

Hi,

I've been experiencing the same behaviour yesterday PT HD 7.2cs2....
Very confusing as this is the first time for me.
It must be kind of random because last week I bounced 20+ mov and they were all in stereo ....????
Digi, can you comment please ?

Hello digi
Will it be solved. This error exist since my 5.? Protools version and is of random nature.
On all systems I have, 80 percent is done in mono!!!!

Can you please provide more information on your system, Pro Tools version, Quicktime version, attached peripherals and any other pertinent info as well as which troubleshooting steps you've tried so that we can investigate this?

Attached canopus video converter

Again. This problem exist also on my 6.93cs2 HD machine on OS 10.4.3
and was on different quicktime versions

I bounce to quicktime dv file.

My only solution to this ist to BNC the the sound separate and then paste it into the quicktime movie.
This is a random problem and depends on the session.
Actually i have a feature that has two parts.
Whatever i Bounce in the first session ist stereo
Whathever I bounce in the second session is MONO
And this is on the same system withe the same quicktime......
