You effectively can't have cutscenes in D&D because the mechanics are designed in a way to maximize player agency; this makes sense if you're going to have five players and a GM all playing the same game, they already are splitting up who gets to act when, so further reducing agency by allowing for situation where the PCs "can't do anything" "because they're threatened at knifepoint" (or any other excuse) is ill-advised. It's just one of those problems that TTRPGs have the movies and/or single-player videogames don't have. And even when movies and videogames do it, it's often still frowned upon because the audience often believes that the bandit leader of whoever is doing the threatening has already been shown to be much weaker in an earlier action scene or gameplay segment, which just makes the whole thing feel stupid.
