This is a very interesting independent film. I know that the source is youtube.com, but there are no credits, so I don't know who made it. First of all there are several types of people in the video. There seems to be every type of person there is. I believe that the film maker meant it to be that way. There are men, women, children, old people, Black people, White people, and Latino people.
The plot of the video is that there is this guy with a set of turntables that can change the outcome of a situation. The man sees an accident, so he takes out his turntables, and turns them backwards. Time begins to reverse, and the man changes the outcome of the accident. This causes a chain reaction where several people get into accidents, or fights.
The Latino people looked as if they were in a gang related incident. There is even a shot of a gun tucked under one of their belts. Later in the film, they are about to get into a confrontation when they see a little girl walk through them. They stop, and look at the little girl. The camera angle shows them from straight ahead, so you can see the size difference between the girl and the men.
There is a Black man in a business suit. He is talking on his cell phone. One of the outcomes is the accident where an old man falls while pushing his wife in a wheel chair (like all old people need a wheel char, not to mention that the MAN is pushing the WOMAN). The woman turns around and sees the black man holding her husband. She proceeds to spray him with pepper spray.
There is a white man who is a drug dealer. He is scruffy looking with a beard. He sees this man dancing for money because he's a student, and he has a sign that says "philosophy major: anything helps." He takes all of his drug money, and puts it in the students tip jar
The turntable man is making this happen. He uses the turn tables to change the lives of people around him. Each action has a re-action. It seemed that everything he did caused another reaction. When he got it just right, everyone seemed to be enticed by a beat that was playing in the music. This caused everyone to see everything differently. This whole video is based off of the music, so could there be a hidden message in there? Does music have the ability to change lives, and "turn back time" in a sense?

The music and the turntable imagery are very important in this film. The main character dude plays a God-like role; connecting youth hip-hop culture with holiness is a very important underlying function of this film.
Swell post. You covered most everything.
