As shown in the video, earth has two tidal bulges at all times. approximately where are these bulges located?

Tidal bulges are always on the opposite side of the Earth.

They are created because of the gravitational influence of the Moon on Earth and inertial's counter balance.

The side of the Earth that is facing the Moon is the closest to the Moon, and the gravitational force is the strongest when the distance is the smallest.

As the Moon is trying to draw the water towards itself, the inertia tries to keep the water at its place. On the opposite side of the Earth, "behind the Moon", the gravitational force of the Moon is the weakest, so inertia is the strongest. That's why tidal bulges are at the opposite side.
