Lately when I record with my 7d when I review the footage in my pc the video looks like things are leaving a trace behind whenever a fast movement is made, I don't know if it's the rolling shutter problem or if I got used to my 120hz monitor and I just see 24fps choppy or I am just plainly losing my mind, but the shots don't feel right to me, the one I chosen to show you it's pretty obvious, whenever the actor moves above average speed horizontally there is a small choppy trace left behind, I know the pan made on the shot is pretty bad but I just want to know if anyone can tell me if there is anything other than rolling shutter problem or confirm it is indeed rolling shutter. Sorry about my english by the way, it's 6 in the morning and I'm just too tired to spellcheck, also it's not my native languanje, thanks in advance any opinion is aprecciated.

Judder (or commonly called strobing), which looks like your problem, looks like this:
