I saw many times on behind the scenes videos film crews watching the picture from film cameras on video monitors. Recently I watched shooting of some commercial with film cameras (not digital cameras) and there was some guy who was watching scopes on monitor forby. How is this possible? There is a video camera built in film camera? (Because I didnt see any video camera there) Thanks for explanation...
 
As you know, a film camera has a mechanical shutter. This spins around and blocks the light from hitting the film when the film is in movement.

Some geniuses, I think Arnold and Richter (Arri), made the shutter a mirror and gave us the mirror reflex camera. This mirror directed all light NOT hitting the film up to a prism in the eyepiece, where we can preview the scene from through the lens.

Years later, in this prism, we have incorporated a very rudimentary but decent video sensor which sends a video signal of the scene out of the camera body. This is done by way of a BNC connection.

That's exactly the reason why when the DoP says "did you see that?" (lets say a muzzle flash) and the Op says "NO" it's a good thing. Because the camera did.

Yeah! It's odd to think the camera Op sees the action that is actually what is going on in 'the dark' when a film is playing in the theater!
