First, refine your negative prompt to explicitly exclude the issues you're seeing—add terms like "flickering, inconsistent shadows, abrupt motion changes, morphing objects." Second, adjust your CFG scale: if the video strays too far from your prompt, increase CFG to 0.6-0.8 for tighter adherence. Third, simplify your prompt by focusing on one primary action or camera movement per shot rather than multiple simultaneous elements. Multi-shot videos with shorter individual durations (3-5 seconds) often yield cleaner results than single 15-second shots with complex action. If issues persist, try
Seedance 2.0 for comparison—different models handle motion and lighting with varying strengths, and testing alternatives can reveal which best suits your specific visual style.
