Protect the Bandwidth of Your Camtasia Studio Screencasts

Posted on Friday May 25, 2007 by Betsy Weber

Bill Myers has done it again! I got an email from Bill about a tool he created for his Camtasia Studio videos...and he has made the tool free for everyone!

Bill has developed a 'video bandwidth protection' tool for use with your Camtasia Studio videos.

With this tool, you can control which site your Camtasia Studio video can be viewed on. And, this tool automatically causes your video to redirect to a specific URL if an attempt is made to display your video on a non-authorized site.

Why did Bill create this tool? Well, he wanted to protect his screencasts that he stores at Amazon S3 (or on any other hosting site) and make it difficult for anyone to steal bandwidth by displaying his videos on other sites.

You can find more information about the tool here. And, Bill even created screencasts to show how to use it.

Thank you, Bill! Check out Bill's site here - it's full of great resources and, of course, lots of screencasts!

Dan :

This is a great idea but it has a fatal flaw that I bring up here in order to improve the product. The protector protects the string the same exact way each and every time. So to defeat this all one has to do is to map the characters using the tool and then you've created a decoder ring which can then be applied to the view source that is still visible.

For example cnn.com processed equals "all,amo" so from that we can determine the following decorder values:
"c" = "a"
"n" = "l"
"." = ","
"o" = "m"
"m" = "o"

I'm sure even this anaylsis is flawed but hopefully this will encourage improvements into the application.
