Book scanning on the (relatively) cheap

Ars Technica has a fascinating article on the trials and tribulations of building a book scanner from a kit.

They lament the lack of software support, however–namely, a program to convert the image files generated by the digital camera into a PDF. Should I point them in the right direction? Why not? The key is Imagemagick, of course.

A fast way to turn lots of images into an Adobe Acrobat PDF file

I have a collection of magazine scans that, inconveniently, came as a series of JPG images rather than as PDFs that are more conducive to reading. I wanted PDFs, so I found a way to turn lots of images into an Adobe Acrobat PDF file.

Building the PDF manually took a good 30 minutes per issue, so I wanted a faster way. Using command-line tools, I was able to convert the entire collection (about 40 issues) in less than 30 minutes. Read more

Cinelerra 1.1.6: An open-source video editor for Linux

I noticed today that Cinelerra, possibly the best-known video editor for Linux, has hit version 1.1.6.
I’ve played around with Cinelerra a bit, and found it competent, but not intuitive. While it’ll do things that Adobe Premiere won’t do, or that Premiere makes exceedingly difficult, there are an awful lot of things that Premiere will do that Cinelerra won’t. Want to mix stills with your video clips? You’ll have to convert those stills to single-frame MPEGs first. (That means becoming good friends with ImageMagick.) Want to pan and zoom? Forget it.

Now, if you’re trying to make the next Blair Witch Project, Cinelerra is more than up to the task, feature-wise. The only question is stability, but that can even be a question with Premiere or with Final Cut Pro. And Cinelerra gets minor point releases a lot more frequently than the commercial big boys.

But if you’re wanting to make documentaries, or, more likely, edit your home movies, Cinelerra will probably frustrate you. Kino will be easier to learn and possibly more feature complete. If you’re willing to pay some money, you’d be better suited with one of MainConcept’s offerings. (MainActor is included in the purchase price of SuSE Linux 8.2.) Or, assuming you run Windows some of the time, you can mess around with the video editor included with Windows Me and XP.
