Well, that's a bit debatable. The famous teaser trailer of TDD for example was a level that doesn't appear in the actual game and the spawning of the monster and the shadow at the end were of course scripted events - but in the end it faithfully represented what the actual gameplay would be like.
It was still a normal, playable level and they simply recorded while one of them was playing it. If you could download it, you'd be able to recreate the exact same situations shown, simply by playing it like you normally would. (or at least that's what it looks like)The monster followed the player because of it's AI, the same way it would in the actual game and the hiding mechanic worked exactly the same, etc...
In this trailer here however, everything feels a lot more artificial, you have this special trailer music, enemies appearing in the most spectacular ways possible, perfectly timed jumpscares, camera movements that probably won't be in the game like this... well, you get the idea
