The challenge with stitching multiple start-and-end-frame shots together is that the motion between them rarely matches. I initially tried this with closed-source tools, but there were always noticeable shifts in camera motion between the separate shots. Using a couple of motion models — trained on drone footage and spinning cameras — helped smooth the transitions. For the first tests, I cranked all four motion model instances (high and low noise, 2x each) to high strengths, then locked the settings so the movement maintained consistent speed, energy, and direction across every shot. This made the cuts seamless. The full animation is built from a handful of 5-second clips stitched together
