Re: WAY OT: Video Sync

What is the sample rate of the original quicktime at? Film and TV is 
usually
rendered to 48khz, purely to cause distress to the audio team.

What level of pitch shift are you experiencing? If the sample rates are 
off,
so will the pitch. You should be able to work out how the sample rates
differ from this.

Have you tried rendering out of Nuendo?
