Why does my video flicker or have inconsistent frames?

Flickering usually results from: (1) prompts with conflicting style or lighting descriptions causing frame-to-frame inconsistency; (2) overly complex scenes with too many elements; (3) high-contrast lighting changes within a short clip. To reduce flickering: simplify your prompt, use consistent lighting descriptors ('constant soft lighting, no shadows changing'), avoid mixing multiple scene transitions in one prompt, and add 'smooth motion, temporal consistency, stable frames' to your prompt.
