In this situation, are you required to refrain from impeding the movement of the pedestrian visible on your left?

In the video, at night you have stopped in a separate right-turn lane; the traffic lights for your lane show a red light with a green filter arrow. Just beyond the traffic lights, a pedestrian crossing crosses your lane, and on the left, on a traffic island at its edge, a pedestrian in dark clothing is stepping onto the crossing in front of you. You are obliged not to obstruct his movement. The answer is: yes.

The Regulation on road signs and signals states that the green filter arrow allows turning in the direction shown by the arrow, on condition that the driver stops before the traffic lights and does not obstruct other road users - and so also a pedestrian who wants to cross your lane. The Road Traffic Act adds that when approaching a crossing, you exercise particular caution, reduce speed and give way to a pedestrian who is on the crossing or entering it; giving way means that you do not force them to stop, slow down or speed up. The green arrow is a conditional permission, which you use only when you will not hinder anyone. At night, a pedestrian in dark clothing can only be seen from close up, so before moving off you look at the whole crossing, and you move off when the pedestrian has crossed your lane.
