Looks like core columns to me.

Why do you post falsehoods that damage your credibility?
Credability: "the fact that someone can be believed or trusted". Quotes from Wikipedia [44] and skeptic.com. Is this credability?
Are visual, actual, real-world, true observations false?
Yes or No?
From your own posted video....
First the collapse of the floor system
Second picture, the vertical columns toppling in after the floor system collapsed
Notice a large block of vertical columns still standing on the left side of the collapsed tower
Smoke!
As i stated in the YouTube description "Shows section of the perimeter structure standing."
Notice the void of Core Structure on the right side.
This is a hollowed out building.
Looks like the core falling after the floor system in the center of your posted video to me...

Like peeling a banana is what you are seeing my friend; perimeter columns falling once core, situated right and more to center, has been taken out.
Core first, rest follows.

Halt the pigeon chess and whataboutism!
Or can all that be intepreted as soft-admittance to the original debate: (i) the cores are not visible (ii) therefor cores did not collapse last?
9/11 and the Science
of Controlled Demolitions
www.skeptic.com...
3WHAT ABOUT THE ALMOST FREE-FALL COLLAPSE OF THE TWIN TOWERS? The key is the “almost” modifier. If I told you I was making almost $100,000 and you found out I was making only $67,000, you’d say I was exaggerating. So stop exaggerating the collapse speed of the WTC Towers! The 80,000 tons of structural steel slowed down the collapses of the Twin Towers to about ⅔ (two-thirds) of free-fall.3 And the core collapsed at about 40% of free-fall speed, coming down last.4 According to Richard Gage: “To bring a building symmetrically down, what we have to do is remove the core columns.” But on 9/11 the stronger core columns came down last, which violates this supposed most fundamental rule of controlled demolition.

Failure of Welded Floor Truss Connections from the Exterior Wall during Collapse of the World Trade Center Towers
app.aws.org...
Summary
Analysis of the connections supporting the composite floor system of the WTC towers showed that at and below the im- pact floors, the greater majority (above 90%) of the floor truss connections were either bent downward or completely re- moved from the exterior column. This was probably related to the overloading of the floors below the impact region after col- lapse initiation. Depending upon weld joint geometry, detachment of the main load-bearing seats was a result of either fracture in the heat affected zone of the base material (standoff plate detached from spandrel) or through the weld metal (seat angle detached from standoff plate). Failure in both cases was assumed to be a result of a shear mechanism as a result of overloading from floors above impacting those below. There did not appear to be a significant change in distribution of failure modes of the floor truss connections when comparing those connections inside vs. outside of the impact region or those ex- posed to pre-collapse fires and those that were not.

Sorry, there is vertical columns of the cores still standing after the complete collapse of the twin towers floor systems.

Introduction
"The connections used in the core area are not discussed in this paper, as few were recovered and the as-built location of those that were could not be ascertained; information on these seats can be found in Ref. 4."
