In this situation, do you have to wait for the red signal to turn green to continue driving?

Why?

You do not have to wait for a green light because the signals of the police officer directing traffic take precedence over the traffic lights. At the end of the video, the officer is standing side-on to your direction of travel, allowing you to proceed despite the red light.
