@duncanrogoff: Seedance 2.5 takes 50 reference images and one 30 second prompt, so your film is decided before you ever open the video model. story first. character sheets on plain gray, because a background makes the model think it's a location. environment plate last and hardest, because everything you drop into a scene takes its light. then one prompt written as timestamped beats. full guide is on my page. #claudecode #seedance #aivideo #ai #buildwithai
