When al-Qaida’s media arm released its first Osama Bin Laden video in nearly three years, most of the media attention was focused on Bin Laden's beard. It appeared either dyed — or perhaps even pasted on. He was ridiculed and a variety of theories were offered to explain it.
But now, there is a running debate among video analysts about whether al-Qaida faked the video altogether —that rather than being new, the September 7 message may have been something recorded at the same time as his last video in October 2004 (and then released with new audio).
The point of departure for the debate is something not noted at the time: that of the 25 minutes of video tape, only three and a half minutes, were moving video. The rest was covered by a still image or a frozen still. Moreover, the still covered the only time references on the 25 minute of tape— references to political developments in Iraq, Britain and France. This lead to the suspicion that the video is not new, but disguised to appear as new.
A senior U.S. intelligence official says they believe the message is authentic, adding “it remains our view that the September 7 Bin Laden video is, in fact, new… interesting but not compelling.”
The leading proponent of the theory is a computer scientist and self-described hacker Dr. Neal Krawetz of Colorado. Krawetz, who makes his living a computer security consultant, tells NBC News in interviews and e-mails that the similarities between the October 29, 2004 tape and the September 7, 2007 tape are too great to be coincidental.

Krawetz does not believe that al-Qaida used the exact same video it did in 2004. Instead, he suspects that al-Qaida had recorded much more video than it released in 2004. There may have even been two sittings. “The main thing I am getting at: I am not saying that they are the same recording,” he said. “I believe they recorded a speech, changed a little, and then recorded some more. (Under this same theory, they may have done it many times and AQ just has not released other videos yet).”
“I am saying the two videos were likely made either on the same day or within days of each other.”

The CIA will not say what it thinks about the possibility, but a senior U.S. intelligence official tells NBC News the U.S. believes the tape is new. He would not discuss the reasons why intelligence analysts feel that way. Another even more senior intelligence official dismissed the possibility that that beard is fake, but would not discuss the reason for the darkened beard.
Despite the debate over the most recent Bin Laden video, there is no debate among private analysts or intelligence officials about the increasing use of digital editing, in some cases sophisticated editing in the videos released by al-Qaida.
Krawetz said there is no evidence of video editing on the scale seen in the videos of his deputy Ayman al Zawahiri.
Krawetz noted in one recent video, Zawahiri was featured in what appeared to be a library, complete with a desk, a banner, a bookshelf and even a toy cannon mounted on the bookshelf.

All of it, Krawetz said, was created digitally using software like 3DStudio. Even the lettering on the banner was added separately. The software permits the creation of wire frame images that can be inserted over a green screen.
“They use multiple overlays,” said Krawetz. “I suspect they have a portable green screen or black fabric they use for the shoot, then edit the video with multiple overlays,” all of which can be seen in a forensic analysis of the video.
“You can tell the number of times it was layered and the order in which the layers were added,” Krawetz added. And a close examination can even determine whether the “green screen” has wrinkles in it. Krawetz said he has noticed the same wrinkle in several Zawahiri videos.
None of the software they use is particularly expensive, says Krawetz. The most basic software, from Adobe or Microsoft, can yield the required effects. (Evan Kohlmann, the NBC News counter terrorism analyst, says most of the software is probably pirated, that every major jihadi site has a download section filled with software from companies as big as Microsoft or Adobe.) Nor is the editing time-consuming, especially since digital editing is now so common in al-Qaida videos.
It's evident that most of these so-called Al Qaeda videos are edited. But what makes these guys so sure it's Al Qaeda doing the editing? Who really benefits from these videos?
