I should mention that, no, I am not a video production expert by any means, but I have picked up a few things by teaching this project several times, and watching many movies throughout my life. Things like using multiple cameras and multiple angles, using loud enough volume, eliminating confusing transitions, and being sure that the audience is really receiving all necessary story information are all vital to ensuring that a film/video is clear and easy to follow. Many students, understandably so, feel that all they have to do is point the camera, and say their lines, and their video will succeed.
While "video production" is the skill at hand, tasks such as these aren't really about videos at all. It's about the ability to learn from your surroundings. A formal video class would be great, but perhaps students are simply able to learn from their own experiences. If given the right tools and opportunities, they may just come to these conclusions themselves.
