Bearing preload (inside and outside) is done from the outside. What you show in the video is normal when the rotor is off the spindle.
The bearing nut (or hub cam assembly for auto hubs) should be tightened to 40-60ft/lbs while rotating the rotor to 'seat' the bearings and races, then backed completely off and re-torqued to, I believe the spec is 15 inch/lbs (barely hand tight).
Do you still have the auto hubs?
