FCPX 10.1(.1) - Ispector slows editing on storyline

The best ting you can do in that case is to find out where the problem really is:

Select the first clips from both cameras and try to synch them with time. If it works, select the next few clips and try to synch them also. Go on until you have a problem synching the clips. Then you will see which clip is giving you problems. You can always add this clip manually to your angle editor if it won't automatically synch with the others.

good idea is this possible last i update fcpx 10.7 to 10.9 thats is problem?

As far as I know not so much has changed for multicam between 10.0.7 and 10.0.9. So I don't think that's the problem.

We do lots of multicam and sometimes we also have exceptional problems with some clips not synching as they should. I have found that most of the times this is related to the multicam video not being recorded correctly, or to an error that has occurred during a recording, and not to FCPX. Shit happens, and it's always the editors who have to clean it up
