Losing Sync During Master to Tape
My 35 minute project is going out of sync by the end of the master out to tape. The project is on my firewire drive. I am mastering to a sony dhr-1000 deck. What’s going on?

[Jason McCaffrey] “The project is on my firewire drive… What’s going on?”
This first sentence answers the last one.
Apple does not officially “sanction” FW hard drives for FCP due of speed and accuracy issues.Try exporting to a QT Movie SELF-CONTAINED and put it on your INTERNAL HD (hope it fits, should be about 6 Gigs).
Then play that QT file in FCP as you record it to tape.

I master a one-hour show every week and hadn’t had any sync problems until the other week when I decided to master from a Firewire drive.
It’s a portable 400 Mbps drive that takes power via the Firewire buss.
I walked away from the process to take care of other things as mastering to tape is usually trouble-free. When I came back 45 minutes later the audio sync was way off.
The drive was really hot, too.
I transferred the project to my 2-drive SATA RAID and remastered the show without a hitch.
As Matte suggested, mastering from a solo Firewire drive might be part of the problem, if not -the- problem. You might be able to stream a single, contiguous file from a solo Firewire drive without a problem. But if the project consists of a lot of clips and effects then the drive may not be able to keep up with the demand.

Omigod! So if I cut a feature (say 100 minutes finished running time and without massively complicated opticals) in DVCPRO HD format and hopefully shot on the forthcoming Panasonic P2, and I store the rushes on external firewire drives, I will have to make a nested sequence of the movie, turn this into a QT file, and then transfer it to my internal SATA drive/s?
Can someone please tell me (a) how much storage space I’m going to need for dailies (say shooting at 15-1 ratio) and (b) how much space I will need on my internal SATA drives for the finished 100 minute movie.
I am coming up with absolutely astronomical figures.
Please forgive my ignorance. I’m new to this High Def stuff.
Am I doomed to mortgage my house to buy some kind of massive RAID system?
Arghhh.
Thanks,
Harry

You can use Media Manager to make a copy of your final (or near to final edit) to your SATA RAID.
No need to make a nested sequence and it can be directed to copy only the media you’re actually using, not what’s been edited out.
The price of a SATA RAID is much less than what you’d spend on a Firewire system with similar capacity.
