"squibs" at WTC - was this video enhanced ?

[BigAl]

25 to 32 seconds into this Twoofer video there are puffs of smoke that are, of course claimed to be "squibs".

Can someone say if this is "enhanced" and if that is the case, can I get a citation I can use?

What is the phrase for the video equivalent of "photoshopped"

 

[Drudgewire]

After squibs blow up, they stay intact and fall down the side of a building?

 

[Gravy]

The puffs are real.

 

[Slayhamlet]

No photoshopping. They're jets of air shooting out of windows from the increasing air pressure within the building caused by the pancaking of the collapsing floors above. You'll notice that the "squibs" only appear after the structure is undergoing global collapse.

ETA: This explains it well.
