The more I've thought about the gaps in timestamps in the Nick Berg movie, the more I think two cameras must have been involved. The timestamps from the video are as follows.
Why the 11 hour difference? Some, seemingly discounting the shot of Nick in the chair at 13:26:24, believe Nick was already dead when the majority of beheading was shown, which falls in the 13:45-and-on range. They suggest the terrorists started cutting at 2:44 and picked up taping again at 13:45, trying to make it look as if Nick was still alive.
There is at least some small reason to think this might be the case, as I imagine it can't be easy to cut off someone's head. It must take time to get through the spine and remove the whole head.
What caught my eye, however, was the similar length of gaps between the two 2am scenes and the two 1pm scenes. Nick starts in the chair at 2:18 and the beheading begins at 2:44, 26 minutes later. Nick also starts in the chair at 13:26, and the beheading is in progress at 13:45, 19 minutes later. If people are wrong in the hypothesis that Nick was already almost 11 hours dead when the 13:45 scene started, then a new explanation might be possible—perhaps two cameras were involved, with times set in different timezones.
If the difference in real time is small between when the beheading seems to start at 2:44 and when the beheading picks up at 13:45, and the difference in timestamp is due to two cameras set in different timezones, then we may hypothesize that Nick was truly beheaded on tape and quickly. This helps explain the fact that Nick began in the chair at 2:18, the beheading begins once at 2:44, then Nick is back in the chair at 13:26, and the beheading then continues at 13:45? (Obviously, there could be other explanations, such as having multiple victims, etc.)
Furthermore, if the difference in real time between 2:44 and 13:45 is very small, say on the order of 1 or 2 minutes, that puts the two cameras at almost exactly 11 hours difference. Strangely enough, this is the difference in time between the timezone of Baghdad and Pacific US time, according to a quick calculation from times at timeanddate.com. Perhaps one camera was set in Pacific time and the other was set in the Baghdad time zone. That just strikes me as strange.
Thoughts anyone?
