DVD's Bad for Archiving

Homemade DVD’s: Going, Going, Gone?

Following up my on recent post about disapperaing data on hard drives, comes a warning about the short lifespans of recordable DVD's. David Pogue, the technology writer for the New York Times, mentions some DVD's he made that after 2 years were already unreadable on many computers. I was taken aback by 2 years. I knew recordable DVD's didn't have a really long lifespan, but I was hoping for something more like 10 years.

The short takeaway is that recordable DVD's are not an archiving format. They are a distribution format.

October Blogwad

"3D Objects from Photoshop in After Effects CS4"
Adobe CS4 is shipping. The thing that most interested me is you can have 3D objects in After Effects. There are a number of limitations on this. This little video shows you the basic of working with 3D objects and discusses the limitations in After Effects (the biggest for me is objects don't respond to lighting in After Effects.) More new features described here.

"Top 10 things you didn't know about the new MacBook"
New MacBook and MacBook Pro's were announced. Each model lost a Firewire 400 port. That leaves the MBP with one FW800 port, but the MacBook with no Firewire port and no way to add it. Some good things about the new laptops too (besides looking really slick.)

"Final Cut Pro: Free plugins to make all fonts available"
Why by version of 6, Apple still hasn't fixed this I don't know. But here's a text plug-in that is supposed to let you use all of your fonts in FCP.

"Final Cut Pro: My free Closing Credits plugin"
From the same guy who made the type plug-in above. The cool thing about this is that it lets you control the lines per second speed of your scroll. I basically almost always use one speed for credit rolls--120 lines pers second. (To know why read from Adam Wilt here). I do keyframe animation of Title 3D to do this, but it's a pain. This plug-in is an easier way to get the speed right, but you lose all the nice type editing features of Boris 3D.

"Build your own affordable SAN -- that works!"
Remember my crazy idea to use Jonathan's computer to build a SAN. This is where I got the idea. I'd still like to do it, but nobody wanted to give me $3K to play around with this, instead of letting editors use the computer.

"What to do if you lose your Pro App serial number"
Title says it all.

"Final Cut Pro Audio Filter Guide Part 1"
"Final Cut Pro Audio Filter Guide Part 2"
Bone up on FCP's audio filters with these helpful articles. Basically they describe what the various sliders do for the filters. However, if you're like me and not an audio person and you don't know what you are doing, then you will probably make your audio sound worse by playing around with filters. On the other hand, I learned the little I know about audio mainly by playing around with filters.

My current favorite filter is Soundtrack Pro's limiter. It works much better than the limiter in FCP. But it's a pain to export to Soundtrack Pro and reimport. It really makes sure that your peaks aren't out of control and cuts off all sounds at a consistent level without distorting it. I usually set it to -10 limit with a +10 boost.

"Another electronic slate for the iPhone"
"Finally a few timecode calculators for the iPhone"
Rejoice iPhone owners (and iPod Touch owners.) Video-centric apps for your iPhone.

"Anything Worth Backing Up…"
Good thoughts on backup strategies and technologies.

"All About Video Fields"
For extra credit, read this long, tech-y article on fields. Written from the perspective of a software engineer, but all the issues come up for video editors too.

Drobo: Your Data Robot

Drobo has been around for about a year and when it first came out I judged it as "cool but not ready for primetime." Drobo is a unique RAID setup for hard drive storage. The biggest drawback was the Drobo only had a USB interface, which is not cool for video editing. Well, this summer Drobo 2 came out with Firewire 800. Data Robotics, the manufacturer, is touting read speeds of 52MB/s and writes of 34MB/s--not too shabby. They say it's good for uncompressed SD, DV, and compressed HD. They cite DVCProHD as OK, but at those data rates I'm thinking that Apple's ProRes 422 is supported too. ProRes maxes out at about 26MB/s--generally I think if the drive's speed is double the needed data rate, then you are OK.

So what makes Drobo unique? It's got a great combination of redundant data storage and the easy-to-use factor. The Drobo case holds up to 4 hard drives, and you only need 2 drives to get started. Your data is spread across the drives in such a way that if one drive failed then you wouldn't lose any data. Need more storage? This is the great part. Just slide in another hard drive of any size. Drobo incorporates you new drive into the existing RAID. If you have four drives in the case and run out of space, then no problem. Simply replace the smallest drive with a bigger drive to get more storage.

My experience with RAID has never gone beyond buying a G-Raid. Whenever I looked into setting up a RAID on my own, there were always enough drawbacks to keep me from making the plunge. It just seemed too difficult to manage all the drives. We are in drive overload anyway. Plus the added expense of more drives and SATA gear was always an issue. Granted Drobo is not cheap. At $500 without any drives, that's a hefty expense to swallow. But I think over it's life it will make up for that in the cost saved by not buying drives with cases, plus the peace-of-mind that you get with redundant storage.

There could be some drawbacks to Drobo. One is that you are putting all of your eggs in one basket. Yes, you are protecting yourself against the failure of a hard drive, but what if Drobo fails. Then you could be in real trouble and pray that Data Robotics will come to your rescue (and do so promptly). Also all of the management seems automatic. That's good if you don't want to deal with the hassle of repairing a RAID with a bad drive, but bad if the maintenance takes place in the middle of a big deadline. If a drive dies, then you don't lose any data. But then Drobo has to start shuffling around all of your data between the existing drives that are still working, and this will take a lot of time. While you are supposed to still be able to access Drobo while it does this automatic maintenance who knows what kind of performance you will get as Drobo and the drives are very busy. Will the Drobo still be able to playback and record video while it rebuilds? So while losing a drive could mean no lost data, it doesn't necessarily mean no downtime for us video editors. But overall, I'd prefer losing no data but have a slower system for a day or so, then totally losing the data.

You are also giving up some of the transportability of a G-RAID. While the Drobo can be moved, it will probably end up having all of your storage on it. If you like to put individual project on a drive, which gets moved around, then Drobo is probably too expensive for that. So it's both good and bad that Drobo can be the only drive case that you will need.

Here's an example of a Drobo system once you get the drives.
Drobo...$500
(3) 500GB Hard Drives...$325
Total Cost...$825
Total storage...930GB
That compares to my favorite type of storage a G-Raid, which gives you the same amount of storage for $355. So that's $500 up front is a lot to ask for. But I'll be thinking about his seriously in the future.

Good Info on Mac Backup Software

"The Evolving World of Backup"
A few years back I bought my first online book "Taking Control of Mac OS X Backups." I basically just copied my plans for backing up at Link TV from this book. A good $10 purchase.

A new version isn't out yet, but the guy who wrote the book has posted some thoughts about trends in the Mac backup realm. I would have thought that Time Machine would have thinned out the available software (you can't beat free.) But apparently, backup software is proliferating and there are lots of new features coming out.

For example he mentions some workable online backup options, namely involving Amazon's S3. Sounds interesting.

Backup is still very confusing, and it takes a real strategy to handle it thoroughly and efficiently. Until the next version of "Taking Control of Mac OS X Backups" comes out, this article has some of the best backup info that I've seen.

Backing Up Projects

"DVD-Rs for Media Back-up in FCP"
This is a good article over at kenstone.net that I found over at freshdv.com. Good tips on archiving projects.

There's a lot in the article about what's the biggest size file that will fit on a single-layer DVD. I guess that's important if your project has long, uninterrupted footage or your dealing with codecs that are more data-intensive than DV. Usually I find in my project that the media manager will cut my media files down to size. However, sometimes I'm preplexed when the trim clips feature doesn't work with media manager and I think it should.
