SpaceX Falcon Heavy USSF-67 Launch 2023-01-15

The rocket enters the lower right just after booster separation and at the beginning of the two side booster's boost-back burn. You can see them slow, then redirect upwards for their trip back to Cape Canaveral until BECO (Booster Engine Cut Off) at approx 1:07. After this you can see them occasionally let out bursts from their cold gas thrusters to reorient them for their reentry burns, which happen off-screen.

The center core continues to burn until about 1:10 (MECO: Main Engine Cut Off). SES (Second engine start) of the 2nd stage begins at about 1:17. After it gets obscured by the tree, it becomes quite hard to see, but it's still there if you look really closely.
