(An interesting aside:  There is a poll right above this LGF blog entry
asking folks if they think Bin Laden is dead or alive.  I was surprised to
see that 58% of the LGF crowd thinks he is dead.)

Video Was Edited

A digital image forensics expert says what a lot of us have already been
thinking: Researcher:
<http://news.com.com/8301-10784_3-9777136-7.html?part=rss&subj=news&tag=2547
-1_3-0-5>  Bin Laden's beard is real, video is not.

On the Friday before the sixth anniversary of 9/11, Osama bin Laden appeared
in a new video, his first since prior to the U.S. presidential elections in
2004. In analyzing the video, Neal Krawetz of Hactor Factor, an expert on
digital image forensics, said in his latest blogs that the video contained
many visual and audio splices, and that all of the modifications were of
very low quality.

Most striking is bin Laden's beard, which has been gray in recent images.
For this video it is black. "As far as my tools can detect, there has been
no image manipulation of the bin Laden portion of the image beyond contrast
adjustment. His beard really does appear to be that color." The Washington
Post has the full video here.

Krawetz says the inner frame of bin Laden was resaved at least twice, and
not at the same time. The images show fine horizontal stripes on bin Laden
and a background indicating these came from interlaced video sources. In
contrast, the text elements, such as the As-Sahab logo, appear to be from
non-interlaced sources.
