For fast-motion scenes that keep morphing or falling apart when generated at normal speed, generate a slow-motion version of the scene instead, then speed it up afterward in any editing tool. This sidesteps a specific AI video failure mode: models struggle to keep fast-moving subjects coherent frame-to-frame, but the same action rendered in slow motion gives the model more frames to keep it stable, and the speed can be restored in post.
