How to Create Motion Prompts

Properly setting your motion prompts brings your Avatar IV creations to life by giving you full control over body movement, gestures, and expression. Doing this allows you to describe exactly how your avatar should move or react within a scene, helping you create natural, dynamic results every time.


Getting Started

When using Avatar IV, you can direct your avatar’s motion using short text prompts.

In the AI Studio, click your avatar, select the person icon in the upper-right corner, and choose your avatar engine.


Writing Motion Prompts with Avatar IV

Each Motion Prompt describes what the avatar should do and how it should do it.

Use the following simple structure:
[Body part] + [Action] + [Emotion or intensity]

Example:

Right arm raises to wave enthusiastically.

Keep your descriptions short and clear. Each line should represent a single movement idea. Avoid combining multiple actions in one sentence — separate them for better results.


Best Practices for Writing Motion Prompts

  • Be specific. Focus on clear, visible actions: point, nod, turn, wave, smile.

  • Avoid overloading. Limit each prompt to one gesture or emotion at a time.

  • Keep timing natural. Avatar IV automatically handles pacing — there’s no need to specify seconds.

  • Control facial expressions. You can include emotions directly in the prompt (for example, smiles gently, looks surprised).

  • Experiment. Small wording changes can produce big differences in performance.
