Exported Quicktime file is 7 seconds longer than original?

[Khashyar Darvich]

I am going to try to export the QT movie with compressor and see if the sync issue goes away.

Please feel post any thoughts that you may have as to why the exported QT movie is longer than the original FCp sequence.

Thanks,

Khashyar

Hi Khashyar,
I belong to the PAL world, but if I.m not wrong, yours is a problem of Drop Frame and Not DF.
In DF NTSC, you skeep 18 frames every 1o minutes of film. Your film is 120 minutes. So you will skeep 12 x18 frames= 216 frames. 216 frames is a more or less 7 seconds. That is the time difference that is anoying you.
Salud,

thank you very much for your feedback, Rafael.

I also think that somehow, the updated version of Quicktime (version 7.13), is playing the film in drop frame, even though I exported the film in non drop frame.

I have exported sucessfully this way several times and it has worked every time except for the past 2 days.

To solve the issue, I exported a Quicktime file, then used Compressor to export an MPEG-2 video file and a Dolby 2.0 audio file. I then imported those into DVD Studio Pro, and the video and audio were finally in sync.

I am curious whether others have experienced the same issue with Quicktime 7.13?

Anyway, I imagine that Compressor produces a higher quality MPEG-2 than DVD Studio Pro (at least I will have more control over the quality of the MPEG-2 conversion).

Thanks again for your thoughts,

Khashyar

Hi Khashyar,
Yes with Compressor you can controll much more the process. Why are you using AAC audio instead of .aiff?
