Reply #68: Compression problem [View All]

It's probably the evil Divx codec, widely used on the P2P networks where many of these clips were found. The codec is free:

There are large chunks thrown hundreds of feet laterally, which would probably not have happened if it were a normal overt CD. (If you can really consider anything on this scale routine.) But to make them look related to the plane crashes the demolitions had to be initiated from higher in the towers than the usual ground floor blow-out. Building 7 type collapses in the towers would have looked very strange and raised a lot of questions.

Given that constraint it's harder to keep everything neat: explosions higher in the air will allow pieces to be thrown further out to the sides and won't crumble the outer walls as neatly as a nice progressive collapse beginning at ground level.
