Reference Mode

Generate videos with consistent characters using 2-7 reference images. Perfect for maintaining character appearance across multiple shots, creating talking head videos, or ensuring visual consistency

How It Works

1. Enable Generate Media - Toggle the Generate Media button in the composer

2. Attach 2-7 images - Upload reference images of the same character/subject

3. Reference Mode activates - System detects multiple images and switches to reference model

4. Select reference model - Veo 3.1 Reference or Kling O1 (auto-selected)

5. Describe the video - Write a prompt describing the scene and action

6. Configure settings - Duration is fixed (8s for Veo, 5-10s for Kling)

7. Generate - Click send to create video with consistent character

Automatic Activation

Reference Mode activates when:

• 2-7 images attached - Multiple reference images detected

• No videos attached - Reference mode is for generation, not editing

• Model auto-switches - Compatible reference models appear

• Element tags - Using @Element tags also triggers reference mode

Supported Models

Model	Reference Images	Duration	Audio	Best For
Veo 3.1 Reference	2-4 images	8s (fixed)	✅	Character consistency with audio
Kling O1	2-7 images	5-10s	❌	Maximum reference images, best quality

Reference Image Guidelines

Image Requirements

What makes good reference images:

1. Same subject - All images should show the same person/character

2. Clear face/features - Good visibility of key characteristics

3. Varied angles - Different views help the model understand the subject

4. Consistent lighting - Similar lighting conditions work best

5. High quality - Clear, well-lit images produce better results

Image Count Strategy

2-3 images:

• Minimum for reference mode

• Works well for simple characters

• Faster processing

4-7 images (Kling O1 only):

• Maximum consistency

• Better for complex characters

• More reference points for the model

What to Include

✅ Good Reference Images:

• Front-facing portrait

• Side profile

• 3/4 angle

• Different expressions

• Various lighting conditions

• Different outfits (same person)

❌ Poor Reference Images:

• Different people

• Unclear/blurry faces

• Extreme angles

• Very different styles

• Inconsistent subject

Writing Reference Mode Prompts

What to Describe

Focus on the scene and action, not the character (reference images handle that):

1. Setting - Where the scene takes place

2. Action - What the character is doing

3. Camera movement - How it's shot

4. Style - Visual aesthetic and mood

5. Dialogue (Veo only) - What the character says

Good Reference Mode Prompts

✅ With Action:

The character walks confidently through a modern office, greeting 
colleagues with a warm smile, professional setting, natural lighting

✅ With Dialogue (Veo):

The character speaks directly to camera: "Welcome to our presentation. 
Today we'll explore innovative solutions." Professional setting, 
confident delivery

✅ With Camera Movement:

Slow push-in on the character as they explain a concept, cinematic 
style, soft lighting, engaging and professional atmosphere

Bad Reference Mode Prompts

❌ Describes Character:

A person with brown hair and blue eyes

(Reference images already provide this)

❌ Too Vague:

The character does something

(Not specific enough)

❌ Missing Context:

Person talking

(Needs setting, style, camera work)

Use Cases

Talking Head Videos

Example:

• 3-4 reference images of the speaker

• Prompt: "The speaker addresses the camera with confidence, explaining key concepts, professional setting, natural lighting"

• Model: Veo 3.1 Reference (for audio)

• Result: Consistent talking head video with audio

Character Consistency

Example:

• 4-5 reference images of a character

• Prompt: "The character walks through a futuristic city, looking around with curiosity, cinematic style, neon lighting"

• Model: Kling O1 (for quality)

• Result: Character maintains appearance across shots

Product Demonstrations

Example:

• 2-3 reference images of a presenter

• Prompt: "The presenter demonstrates a product, showing features with enthusiasm, bright studio lighting, professional setting"

• Model: Veo 3.1 Reference (for audio)

• Result: Consistent presenter across multiple shots

Narrative Scenes

Example:

• 5-7 reference images of main character

• Prompt: "The character enters a mysterious room, camera follows their gaze, cinematic style, moody lighting, suspenseful atmosphere"

• Model: Kling O1 (for quality and longer duration)

• Result: Consistent character in narrative scene

• Duration: 5-10 seconds (variable)

• Aspect ratio: 16:9, 9:16, or 1:1

• Audio: Not supported

• Resolution: 720p-1080p

Best for:

• Maximum character consistency

• Longer videos (up to 10s)

• More reference images (up to 7)

• High-quality results

Limitations:

• No audio generation

• Fixed aspect ratios (no auto)

Tips for Best Results

1. Use varied reference images - Different angles and expressions help

2. Keep images consistent - Same person, similar quality

3. Describe the scene, not the character - Reference images handle appearance

4. Use appropriate model - Veo for audio, Kling for more references

5. Match aspect ratios - Reference images should have similar ratios

6. Be specific about action - Describe what the character does

7. Include camera movement - Helps create dynamic videos

8. Test with different image counts - Find what works best for your character

Troubleshooting

"Reference Mode not activating"

Solutions:

• Ensure you have 2-7 images attached

• Check that images are properly uploaded

• Remove any attached videos (reference mode is for generation)

• Verify you're in Generate Media mode

"Character doesn't look consistent"

Solutions:

• Use more reference images (4-7 for best results)

• Ensure all images show the same person

• Use varied angles and expressions

• Try Kling O1 for better consistency

• Check image quality (clear, well-lit)

"Model doesn't support reference mode"

Solutions:

• Switch to Veo 3.1 Reference or Kling O1

• Check Supported Video Models

• Most models don't support reference mode

• Reference mode requires specific models

"Duration is wrong"

Solutions:

• Veo 3.1 Reference: Fixed at 8 seconds (cannot change)

• Kling O1: 5-10 seconds (variable, set in settings)

• Reference mode has limited duration control

• Plan your content for the available duration
