Here's a clip of B12's landing burn and catch by the chopsticks from LabPadre's Rover 2 stream.
I believe when you create a clip from an ongoing YouTube live stream, it will (at best) only work as long as the footage you selected is still available on the stream. And I believe YouTube only keeps the most recent 12 hours of footage.
(What they should do is create a permanent copy of the relevant footage, assuming the channel owner permits it.)
