I watched the video and noted that the shift indicator would briefly jump to P when the locks were actuated. When you shift the car out of Park the doors automatically lock. There is a sensor in your shifter assembly which detects when the shifter has moved from park and then this locks your doors. On the other hand, the automatic door locks are controlled by the body control module which could be failing as well.
There is a door lock relay, but it is part of a printed circuit board and not replaceable.
Before we jump the gun and start checking or replacing everything, lets start by checking for a weak ground. If you look at the pic I attached, it shows where the ground for the circuit is located. Check that first.
Let me know what you find.
