Iranians are Persians, not Arabs. They speak Farsi, not Arabic.
As for the video. My grand daughter went wth her father to Tehran for a month, last October. Anytime she left a private residence, she had to wear the hijab, with her head covered.
I seriously doubt that video was shot in public places. I sent the video to my son-in-law for his comments. I'll report back.
