So that whenever two parts on the timeline are sequential frames, it automatically optimizes by making them into 1 item (excuse me if I am not saying this quite right). So if you are cutting, dragging, editing, or whatever and somehow frame # 40 ends up right next to frame # 41, it optimizes them together. This optimization is sprinkled all over the code." Some time ago, in some tests on Motion Tracking, I had put two adjacent motion-hv plugins: at the end of the calculations they had merged into a single plugin. Maybe this is an example of "build in optimization"?
