Despite comments in this thread to the contrary, meaningful metrics can be collected from cell phone video.
In this case, I am looking at the shadow of the wing to judge the relative position of the 737 at it crosses runway landmarks.
Here's is what I note:
2:11 Early edge of taxiway H. About 1475 meters of runway remaining.
2:21.5: Middle of retired taxiway. About 780 meters of runway remaining.
2:27: End of bar at outside edge of runway. About 356 meters of runway remaining.
So, in that last stretch, the 737 crossed 424 meters in 5.5 seconds. Averaging 77 meters per second or 150 knots.
That's averaging roughly 150 knots.
At that point, he still had 350 feet on runway in front of the wing - but did not rotate for another second.
So as best I can tell, this was a delayed rotation.
