Created as proof of concept, this is a highly amusing video, very funny indeed.
This is a totally fake Bin Laden video, which is more convincing than the real thing.
ABC's blog "The Blotter" is today covering the fake Al Qaeda video story.
Al Qaeda Videos May Be Doctored

Maddy Sauer Reports:
Media and terrorism experts alike have remarked on the increasing sophistication of al Qaeda propaganda videos that continue to be released by the group's media wing, as Sahab.
One computer expert, however, has conducted extensive image analysis on many of the videos and concluded that in many cases the tapes were likely doctored to give a false impression of the speaker's location.
Neal Krawetz, founder of Hacker Factor, a computer security and consulting firm, created a computer program which he uses to analyze screen frames from various al Qaeda videos, including those of al Qaeda No. 2 Ayman al Zawahri and American al Qaeda commander Adam Gadahn. His software suggests that in many cases the sophisticated backgrounds were likely added after the video of the speaker was recorded.
Photos: See What's Behind al Qaeda's Propaganda Tapes
Neal Krawetz, a researcher and computer security consultant, gave an interesting presentation today at the BlackHat security conference in Las Vegas about analyzing digital photographs and video images for alterations and enhancements.
Using a program he wrote (and provided on the conference CD-ROM) Krawetz could print out the quantization tables in a JPEG file (that indicate how the image was compressed) and determine the last tool that created the image -- that is, the make and model of the camera if the image is original or the version of Photoshop that was used to alter and re-save the image.
Comparing that data to the metadata embedded in the image he could determine if the photo was original or had been re-saved or altered. Then, using error level analysis of an image he could determine what were the last parts of an image that were added or modified.
