why motionbox is slow for me ?

Hello guys

Thank you for developing this awesome piece of software, I like using motion box for quick videos check but I have a constant problem, the program takes 2 to 5 seconds in loading to be able to play that part of the video , this doesn't change with changing the quality to the lowest 144, so I think its problem with accessing YouTube or something, this doesn't have at all if I select 144 in the browser I would be able to skip and play the video instantly without any wait or loading.

if anyone can indicate to me what's the problem, I would be grateful.

You may get a faster answer by reporting the "issue" on the MotionBox git hub.

I observe the same behavior on my side.
