If I export a uncompressed (I have to do uncompressed because it's xdcam footage) qt movie- then compress it in Sorenson to a qucktime with MPEG4 audio- the audio plays too fast.  The quicktime that came from Avid is fine- or appears to be fine- meaning audio plays at the correct speed,  I didn't have this problem before I upgraded.  If I choose a different audio compresser- like IMA- the audio is fine.

Bump.... anyone?

What is the specs of your audio export?

Quicktime Reference- use marks use enabled tracks

digital maastering

flatten video tracks

render all video effects

mixdown audio tracks

Wave

48khz

16bit

and USE AVID DV CODEC (which seems odd now that I look at- but I'm not sure what it means if I'm exporting a QT ref movie)

and RGB color

What are the audio specs of the Sorenson MP4?

Interesting-  NOW THE AUDIO PLAYS TOO SLOW!

I just went through the whole process again-  export uncompressed Quicktime (this file plays fine in QuickTime)

Audio Settings on the Export are Uncompressed, 48kHz, sample size 16, Channels 2
Video is Uncompressed, Millions plus depth and quality High

Sorenson Audio settings
