Thanks for sharing the video, and sorry about the long delays in anyone getting back to you.
It looks like your motors are not connected in the correct order, or your ESC's are not calibrated correctly.
What you should do is open up mission planner and connect via the terminal and run the motor setup. This will help you to double check if the motors are connected in the correct order and to the correct APM output. The video itself is kind of old but stil very helpful.
Hope that helps
