Middle mouse scrolls backwards

[#1]

Hello, when I attempt to scroll forward in a video sliding the middle mouse upward, the move goes back in time. In other words, When I scroll upward on middle mouse the video essentially goes rewinds. In short, the middle mouse settings appear to be backwards. 

Can you please help. Thanks

That is how a mouse works.

Most likely you are on a Mac. Magic mouse? Might be able to change this in the mouse settings of your mac.
