The above clip is taken
from this longer video of the WTC-7 collapse, which itself is a small
segment of the Naudet brothers' documentary "9/11" , (with enlargement and cropping by
Webfairy) : The following are some frames.

Looking at the upper right-hand
corner of the building we see a rapid series of small explosions
travelling upward just as the building itself begins to fall. The
size, placement and timing of these "puffs" is very consistent with
squibs from cutting charges of the type used in professional controlled
demolitions, and in fact nothing but small explosive charges could
create such an appearance. The decreasing volume of the
building from the collapse itself could not create enough pressure to
cause such localized high-velocity effects, and this early in the
collapse would have only created a modest overpressure.
