Prompts for people and characters in AI video

People are the hardest thing for AI video to get right, and the most convincing when it works. Clear, simple descriptions and small actions give the most natural results.

Describe the person

  • Who: “a woman in her thirties”, “a young man with curly hair”.
  • Style and clothing: “in a denim jacket”, “in a white chef's apron”.
  • Expression: “smiling”, “focused”, “surprised”.

Give one small action

Small, everyday actions look most real: picking up a cup, turning to the camera, taking a sip, laughing. Big or fast actions in a few seconds often look unnatural.

Example
A woman in her thirties in a denim jacket picks up an iced coffee from a café table, takes a sip and smiles, handheld camera, warm morning light.

Common problems and fixes

  • Odd hands: keep hands still or holding one object.
  • Faces change: use shorter clips, or Kling 3.0 Pro for several shots of the same person.
  • Stiff movement: add “natural, relaxed movement” and a handheld camera.

Use real people responsibly

Do not use a real person's face, name or likeness without their permission, and do not make videos that could mislead people about what someone said or did. Our Acceptable Use Policy has the details.
