Why does the suspension look like i drove over a rock?

I think I see something unusual
In the slo-mo, I see the rear of the car rise and hang there for a long time.
Then it begins to rise more and the pinion rotates waaay up,like the power was twisting the front section of the spring
Then the pinion does an up and down dance, like the u-joint is bound up, but I think it's just the springs winding up and letting go..
Don't know if it means anything.......

At 42 seconds, you can see the lower shock mounts twisting downwards
At 56 seconds the the shock anchors are twisted waaaaay down. and the dance begins. watch the shock pins. The dance doesn't end until the shift. If you watch the springs and do some deductive reasoning, I think those front spring sections are alive! rippling back and forth.
Don't know if it means anything.......
I'm going to make another slow mo that's not as slow and see if it becomes less blurry............ maybe a couple different speeds.
Thanks everyone for your help so far.
