Never heard of it. Interesting.

[rob norris] “First question is what is the best way to take this 24p HD footage and export at 29.97 fps, keeping the 23.98 fps look, for on-air?”
The first step in the workflow is to capture in HDV 1080i. Done. Skip the rest. Edit. Output 1080i. You’re there.

Exabyte has a FW800 external tape backup device that some folks have pointed to. It’s about $1200–cheap. Trouble is, it’s pretty slow. I believe the transfer rate is 6MB per second. That sounds like about 44 minutes per 16GB card. Ugh. The cartridges are not entirely cheap either.
Jan Crittendon Livingston from Panasonic, has mentioned using a RAID-1 removable drive setup. The idea being you backup to two hard drives at once and then swap out the drives and store them when they’re full. One hard drive sitting on the shelf seems awfully risky–two is safer. Wiebetech has a really cool trayless removable drive system that would be a dream for this kind of thing. What do you think of this?

I’ve gotten a lot of good info from the reviews on AMUG.org and BareFeats. Then look at the sites of major manufacturers–G-Tech, Sonnet, Cal-Digit, LaCie. Adaptec has great information about the different kinds of RAIDs and the advantages of each.

A major consideration is the bus you will need to connect to and what other equipment needs bandwidth on the computer’s busses. So, will you go with a RAID that connects via FireWire or via SATA?
Other major topic is what flavor of RAID and how big does it need to be. I could assume you want a two-drive RAID-0 system, but maybe not.

The thread started out with mostly misinformation. It’s better now.

Got it. That covers all the bases.

[walter biscardi] “If it’s fast enough, RAID 5. You give up an entire drive, but it’s total and instant redundancy. At least on our systems it is.”
Total? RAID-5 can withstand one drive failure without losing the volume. So, with one failed drive, you’re vulnerable–just as vulnerable as you would be with RAID-0 or no RAID at all. That’s why it’s good to have a hot spare with RAID-5 and a controller that can automatically rebuild using the spare. RAID card manufacturers state that you still need a backup with RAID-5 if your data is irreplaceable.
Regarding the “instant” part, the RAID will perform at reduced speed if one drive fails. If you have a lot of drives in the set, you’re going to have speed to burn, but it will still be slower until the failed drive is replaced and the RAID is rebuilt after a couple hours or so.

From what display is your “After” frame grab taken? It appears to be the Canvas of FCP. The Canvas cannot properly display interlaced (60i) video. You must view it on a regular TV or NTSC monitor to properly judge the quality.

It only has to be big enough to cover your eye, yeah?

Great workaround. This could come in handy for a lot of people.
