why don’t i want mirrored (raid 1?) discs?

Mirroring means the same data is copied to two drives simultaneously. This is great when you transfer P2 material in the field as you instantly create a backup. But for editing, you gain no speed advantage which is the point of a RAID array.

if i want a Raid5 set up is it best to get someone to build it for me or can you buy this stuff off the shelf?

The vendors I mentioned in my prior post all make off-the-shelf turnkey systems. You get a tower with the drives and a controller card for your computer. Some system have the RAID controller in the hardware and you simply connect to your computer via Firewire 800. You’d probably purchase this kind of system from a local reseller. They should know of all or most of these companies. If they don’t I’d look for another reseller.

what is better about raid5 and why would i need 4 smaller disks? is it safer? quicker?

RAID 5 gives you redundancy. What that means is if one of the 4 (or more) drives in the system fails, you put a new drive in the system and it automatically rebuilds and recovers the data that was on the failed drive. RAID 5 needs a minimum of 3 drives to work. More drives is always better as it increases the data rate of the array. If you’re going to edit HD, you need more speed.

In addition to Dave’s suggestion, try with Frame Controls off, or change the quality settings there to best.

Try trashing Compressor’s prefs.

I’ve seen many posts about troubles with LaCie drives. Checkout G-Tech, Dulce Systems, CalDigit, Maxx Digital. You’ll find most of them in ads to the left or right on the Cow. As far as specific drives used in the system I’d go with Hitachi or Seagate. You do not want a mirrored raod. That’s where both drives write the exact same data simultaneously. You’d be better off with a system with more, smaller drives, say 4 – 250GB drives to make your 1TB. This lets you have some redundancy (raid 5) so if one drive fails you can rebuild it from data on the other drives. Here’s a link about raid 5 https://www.pcguide.com/ref/hdd/perf/raid/levels/singleLevel5-c.html

Have you checked out Flanders Scientific (see yellow ad to left on this page). Not inexpensive, but way less than TV Logic.

Also, please tell us about your setup: computer, RAM, OS & FCP version, hard drives, how you monitor, etc.

Have you trashed FCP prefs, repaired permissions and run Disk Warrior? These are the first steps I take when FCP acts abnormally.

I had created a custom 23.976 preset for BitVice that inadvertently removed the pulldown flags from the mv2 so Compressor wouldn’t import it. I used the BitVice preset and all was well.

My suggestion is to test the workflow before you shoot. This way you can work out any wrinkles in advance. Also, search the Cow for the many suggestions of how to sync your 2 cameras during the shoot. It will make your editing life much easier.
