Gotchas

• Duration range is 2–12 seconds — values outside this range will fail
• Higher resolutions (1080p) combined with longer durations take significantly more time
• premium service tier costs more but generates faster
• seedance-acting-pro excels at facial expressions and character acting versus pure dance
• Image-to-video requires a single image_url — the person/subject in the image becomes the animated subject
• Task states use "succeeded" (not "completed") — check for this value when polling
