The pre-fight in most of the dungeons cinematic don't look to be that long. Maybe 2 to 4 minutes at most, with most being less then a minute long. It's the ones that play when you win that are super long. And those, I've noticed it's difficult to give a commendation or roll for loot if it's your first time in the dungeon. Why? Because everyone's going to be leaving while you're still watching the cinematic.
