FCP clips and master lose sync

[Trevor Asquerthian]

I’ve now seen this too many times in too many different setups.

Recapturing is not an option often – no deck available, tape in a different country – or the media was tapeless to begin with.

I suspect it is down to the inherent non frame-based nature of quicktime.

One manifestation I have now seen twice is where I have revealed part of a clip that means that it is now partially rendered. The unrendered (green preview) section plays and then does a jump cut to the rendered section.
