You can have the best footage in the world, the best actors, it really doesn't matter unless you have a great editor who can structure your video to have the most impact.
VFX can range from full blown hollywood action scenes, to subtle, unnoticeable touchups. In real-world scenarios the latter is mostly applied.
Before you start shooting, or even start to work on your storyboard, you need a good concept. Even the simplest interview scene can have something that separates it from the rest.
Although my main experience is editing and post production, I also direct and shoot videos as well. This helps me tremendously to overview the whole process of video production.
You have multiple, non matching cameras shooting an interview? You have more scenes in different locations? Don't worry I have you covered!
Motion design is becoming an increasingly important competency. It's a simple but effective way to communicate with the viewer and add depth to your story.
You don't have a working prototype, but you want people to get involved with your idea? This is the way to show your product in it's final form, even before it's in production.
Beat by beat.
