600 PowerMacs Make One DVD
vaporland writes "NYTimes.com has this story about using a network of 600 PowerMac G5's to scan original movie negatives at 4000 lines per inch and create high-resolution digital recreations of classic movies."

Actually the workstation that controls the scanner runs linux.
You can see an overview here of the machine.
If you look at the press releases they came out with an add-on that allows the machine to scan at 10k lines in 12 seconds.
As an aside, the smaller film scanners that capture 35mm slides have Digital Ice to remove surface blemishes. Part of it works by shining an infrared light through the film. The infrared light is unaffected by the different shades of color, but the dust "stops" it and therefore is detected. Quite ingenious.
I imagine as expensive as this machine is, it uses this and other techniques to remove surface and film imperfections. If you use an original to scan that has been well cared for, the results should be impressive.
I toyed around with the idea of homebrewing such a machine to convert some old family super8 movies.
The two problems that you are going to have is the film transport, and the amount of time it takes to scan the film. As it stands, it would be time intensive to build such a machine and technically challenging. That and not having a workspace, it will have to wait for another day.

That article is so full of incorrect statements, its sad it got published in such a reputable paper.
It confuses horzontal and vertical resolutions left and right, mixing the 4k horizontal resolution of a 4k scan with the 1080 vertical resolution of HDTV and extrapolating silly figures from the result, as one example.
4k scans of film aren't uncommon, although this might be the first time it was done for archival purposes.
No matter what the article author says, you'll see zero difference between a 4k, or 2k scan on a DVD transfer. A 2k scan is aproximately HD resolution, so there would be a benefit for HD formats to have a 4k scan, to eliminate noise, etc.
The article was also unclear why such horsepower is needed for such a mundane process as scanning and storing film. Thats a problem thats been solved for a decade or more by the film industry, where working with 4k frames is commonplace.
