Different screenwriting manuals talk about it differently. (I bought most of mine when I was studying screenwriting at uni, but I know at a bunch of romance writing conferences people have given talks recommending one screenwriting manual or the other: usually Save the Cat or something by Robert McKee).

I can't say I love the effect of screenwriting on prose fiction, though I think that rapid-cut pov switch is more influenced by watching movies than by reading about how to write them. I do think there's a lot to be said about the way screenwriting and prose fiction work differently, though; a film can get away with a 30 minute fight scene, but a 30 page fight scene in a book is likely to be very dull, & etc.
