AI Video: Prompt Writing Techniques for Generating Characters 

 

1.To avoid shaky camera movements:

Use keywords like: Fixed perspective, fixed camera, static shot, unmoving camera, no shaking, stable image

 

2.Character Description

2.1 Number of Characters:
Default is one person, unless otherwise specified.

2.2 Character Identity:
Describe clearly: man/woman, child/elderly, chef/worker, etc.

2.3 Appearance Description:
Examples:

-Wearing simple clothes

-Short hair / long hair / bun hairstyle

-Wearing a light blue dress / beige casual short-sleeve top / white shirt / yellow long-sleeve sweatshirt

2.4 Ethnicity:
Chinese / Asian / European ...

2.5 Framing:
Specify whether the character is:

-Full body

-Half body

-Full body shown in frame

 

3. Character Actions

 

3.1 How does the character enter the scene?
If not specified, the default is usually "walking into frame."
However, there may be unexpected behavior — for example, the character floats in from the sky. To avoid this, clarify how the character enters.

 

3.2 What does the character do?
For example:

-Sits on a stool

-Sits on the bed

Note: It’s important to anchor the action to a specific object (e.g., "sits on the black stool") — otherwise, the AI may generate a character sitting on a self-generated stool.
