Yes, left rudder to stop the wind blowing the tail to the left, and thus the nose to the right, then right aileron to stop what happens later in the video as the plane tips over to the left.
This is just a crosswind situation as you say.
Other than maybe tweaking your controls so you are more comfortable with making precise rudder input. You mention -50% sensitivity. I have mine at -29%. I also have no deadzone configured. It might be worth tweaking both those settings until it feels more comfortable. Try manually configuring crosswind weather at lower speeds, then slowly work up while being able to maintain the centre line.
