Place it at the exact frame the choice confirms, after you have built up the decision in the edit. Follow it with the dun dun dun sound for a second beat, or let the scene carry on without another effect.
Over dit geluid
This is a short, loud sound effect lasting about two and a half seconds, built as a deep ominous hit with no voice or melody. It gives a listener a sudden sense of dread and tension, like a choice has crossed a line. It plays in the Chapter 5 weird route scene at the moment the Proceed option is selected.
