Read through this short paper, particularly chapter 4. It breaks down the editing decision-making process and this can help us analyse what we're doing when we're editing.
Make a short video (3 - 5 mins) about the editing patterns and underlying editing heuristics that you perceive to be at work in a specific section of a film/programme/video.
Here's a big hint: You can select anything at all to work with, but bear in mind cutting patterns are easier to identify in certain genres like comedy, horror, music video, light entertainment.
