Glad to see they spin-stabilized the image. I’d get seasick watching the video otherwise.
My first thought was of the spin, and I actually sat in front of my console, attempting to visualize the mechanics of it...before I realized it was April Fool's Day.
Only a matter of time, though.
Good one!
It’s just a matter of matching the frame rate to the bullet’s spin rate. Basic math. We see that all the time in old movies, where the wagon/train wheels seem to be moving slowly forward or backward, or occasionally not moving at all.
