In regards to making things more interesting, make sure you use lots of various music and sound effects during editing. By adding certain sound effects at those special times like when someone trips or something like that, you will get huge chuckles. Same goes for some somber mood music and the use of slo-mo during maybe a sad time that has occured in the past. Adding various video effects will also add some interest as well. All of this of course would have to be done in your editing application.
But the one thing that you really have to watch out for, which was already mentioned a few times by the other guys is don’t carry on too long on the same scene. Chances are you have a ton of footage waiting for you so make sure you keep the show moving.
