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.”
