Silence at beginning of file when roundtripping FCP>STP

Postby cnse » Tue Aug 31, 2010 11:43 pm

Frequently I edit videos of live music performances. A big part of this process is enhancing the sound. Recently I've noticed that when I round trip audio files between Final Cut Pro 6.0.6 and Soundtrack Pro 2.0.2, the resultant processed audio file has 2 to 4 frames of silence at the beginning. This is a problem when I have multiple audio files that make up a continuous performance. Usually my go-to processing chain for quick enhancement is something like: Channel EQ>PSP Vintage Warmer 2>Channel EQ (mostly for the RTA)>Ad Limiter.

Does anyone have any ideas about why this process creates silence at the beginning of the files?

Thank you for any thoughts on the matter.
You may ask, "Why do you have file divisions in the middle of songs?" It's because often I record video directly to disk using an old Firestore, and it has a 2GB file size limit, so when shooting a long concert, the footage is divided into 2GB chunks, which invariably never happen between songs (where a few frames of silence would be less annoying)
