If you think it is hitting to hard start with tightening the extension on the shock, make it tighter. I assume this is a ladder bar, caltrac or 4 link car given the tire size. If that is the case it is simple physics really. The very first move with all those suspension types is to drive the housing/tire into the ground, that is controlled buy the shock.

Cant tell a lot on the video for sure. Looks ok for what can be seen. But hard to say definitively.
