AI Character Animation Guide

AI character animation brings AI-generated characters to life. From subtle expressions to full body movement, maintaining character consistency while animating presents unique challenges.

Character Animation Types

Expression Animation

Facial movement and emotion:

• Lip sync for dialogue
• Eye movement and blinks
• Emotional transitions
• Subtle micro-expressions

Body Animation

Full character movement:

• Walk and run cycles
• Action sequences
• Gesture and posture
• Dance and performance

Idle Animation

Subtle life signs:

• Breathing motion
• Weight shifts
• Hair and cloth physics
• Environmental reaction

Maintaining Consistency

The Challenge

AI animation can change character appearance. Maintain consistency through:

• Detailed reference images
• Consistent prompt elements
• Character LoRAs
• Multiple generation attempts

Techniques

Reference-Based:

• Start from character sheet
• Use same source for all animations
• img2img with low denoising

Prompt Anchoring:

• Include character details in every prompt
• Consistent style descriptions
• Same quality modifiers

Post-Processing:

• Face restoration if needed
• Color grading for consistency
• Blend frames for smoothness

Animation Workflows

Single Character Animation

1. Prepare high-quality character image
2. Define motion in prompt
3. Generate animation
4. Review for consistency
5. Iterate if needed

Multi-Character Scenes

1. Establish scene composition
2. Animate characters separately if needed
3. Composite or generate together
4. Ensure interaction feels natural

Dialogue Scenes

1. Generate neutral pose
2. Use lip sync tools
3. Add expression changes
4. Time to audio

Prompt Examples

Subtle Movement:

[character description], subtle breathing animation, gentle head movement, natural idle motion

Walking:

[character description], walking forward, natural gait, smooth movement

Emotional Expression:

[character description], transitioning from calm to surprised, expressive face, emotional animation

Action:

[character description], dynamic action pose, powerful movement, dramatic motion
