The uncanny valley for faces & hero products.
Pure AI ads have one limit: they can't quite get past the uncanny valley for human faces and complex hero product shots. Even with Kling 3.2 and Veo 3.1, the moment a model has to render a specific human face in close-up holding a specific product, something feels slightly off.
The fix isn't better prompts. It's better workflow. Shoot the close-up real. AI the rest.
