Question on people in videos

I see a lot of videos where there are multiple people in the video with clearly visible faces. With the context of the videos and the amount of people in the video I am sure these people never signed a released. So can anyone give me a basic reason of what makes these video ok? I mostly come from a photography background.

I was under the impression that any recognizable people had to sign a model release. I had a video that only showed my own hand in the video and it got declined for no model release. So I'm just curious.

I guess I didn't answer this correctly the first time you posted it?
