Write these from the learner's point of view - what will they be able to do once they've participated in your learning module? By articulating these before you begin, you're most likely to cover your main points without too much wandering. Keep in mind that the ideal length for a concept video is under 8 minutes. When defining your outcomes, it might help to think about how long it will take you to teach that concept and how you might break larger concepts down to smaller ones.
