Premiere Pro in the big leagues, cutting David Fincher’s next film.

[Andrew Kimery] ” Some how it seems like the ‘processing overhead’ involved with handling multicam clips gets compounded each time the sequence is duplicated. I’m also using XDCAM EX (EX3) and some AVCHD (FS700) and that might be part of the problem too but I don’t have any other media to test with at this time.”

It’s not likely to be the footage codec. Usually inactive sequences draw no processing power whatsoever, once the project fully loads and all the material is confirmed that’s clips are still where they were last seen and that they haven’t been modified. It must be some strange multi-cam related bug as you say. If you haven’t already reported it please do so. One of the advantages of CC is more rapid bug fixes.
