Humans are the hardest test in AI video: viewers have evolved to detect wrong faces, and lip-sync errors register in a single frame. This is the category with the highest retake ratios — plan ×2 to ×3 even on premium models — which reshapes the cost math: a $0.40/s model that lands in two takes beats a $0.10/s model that needs seven.
Veo 3.1 owns dialogue. Kling 3.0 owns movement — walking, gestures, sports — and identity consistency across a multi-shot sequence. Sora 2 Pro owns interaction: hands holding objects, people in physical scenes. For pure talking-head content at scale, also consider dedicated avatar tools, which price per minute rather than per generation and undercut all general models on that one job.
Whichever pick fits, pressure-test the budget in the calculator with your real clip counts — and remember every rate above multiplies by your retake ratio.
