Final Cut Codec error
 

I have digitized my first A1 footage into the latest version of Final Cut.

When I export anything, the in and out point are not accurate. The video starts earlier and ends earlier by around a second.

It's also evident when I try to export a freeze frame. I get an earlier frame, instead of the one I have chosen.

What's up? Perhaps I have set this up all wrong.

I also get "codec error" at times, and it seems to refuse to conform.

Any help is greatly appreciated.

Thanks!

Moved from Canon XH to NLE - Mac.
