Consistent Characters in AI Video: The Complete Multi-Image Fusion Guide

The Character Consistency Challenge

You prompt an AI to generate a video of a detective walking through a rainy street. The result looks great — but in the next scene, the detective has a completely different face. Sound familiar?

Character inconsistency is the number one complaint from AI video creators. Multi-image fusion solves this problem by anchoring the AI to reference images of your character.

How Multi-Image Fusion Works

Instead of relying solely on text descriptions, you provide the AI with 3-7 reference images of your character from different angles. The AI analyzes these images to understand:

• Facial features and proportions
• Skin tone and hair color
• Clothing and accessories
• Lighting and style

Every generated frame then maintains consistency with these references.

Step-by-Step Workflow with Domer

Step 1: Create Reference Images

Use AI Image Generator to generate high-quality character portraits from multiple angles. GPT Image 2 delivers photorealistic quality ideal for reference images.

Step 2: Generate Video with Fusion

Upload your reference images to Image-to-Video and describe the desired motion. The AI will use all reference images as visual anchors.

Step 3: Add Cinematic Motion

Enhance natural movement with Seedance 2.0 for fluid character animation. For film-quality output, pair with Kling 3.0.

Step 4: Expand with Text Prompts

Use Text-to-Video for background scenes and establishing shots, then blend with your character footage.

Best Practices

• Diverse angles: Front, profile, three-quarter, and close-up shots
• Consistent lighting: Match lighting across all reference images
• High resolution: Minimum 1024x1024 for best results
• Clean backgrounds: Remove distracting elements from references

Applications

• Short films: Independent creators can produce series with consistent protagonists
• Brand mascots: Maintain your brand character across all marketing videos
• Educational content: Create a consistent presenter for course videos
• Social media series: Build recognizable characters for episodic content

Troubleshooting

If your character still drifts between scenes:

• Add more reference images (up to 7)
• Ensure reference images share the same art style
• Use more specific prompts describing the character
• Try different model combinations

The key to success is treating reference images as the source of truth. Explore all tools at AI Tools.
