Final burn though? That time is just over a minute away from reaching the drone ship.
The side cores do a burn just under 90 seconds before their final landing burn...
Should be final. Re-entry happened previously (edit 28:55) and the landing legs deploy during the shot.
I'm also not seeing any movement from the grid fins (which are deployed).
Any reason to think the camera is rotated 90 degrees? Smoke off legs near the end seems to match video up with world up.
