There is an option in media managing that gives you an opportunity to put in handles. I usually use 2 to 3 seconds, it adds about 5 gigs to your file size though. Hope this helps.
I use an HVX and then I transfer the P2s through a panasonic AJ PCD20 card reader, I take the cards and copy them into an external hardrive connected to my Dual Core apple then I open of Log and Transfer in FCP and take the files out of the hard drive and convert them onto my internal hard drive, than finally I place them on a server. Does this problem sound like an importing problem or filming?
