Your person profile is the foundation of thumbnail consistency. A well-created person profile ensures your face appears consistently across all your thumbnails, building recognition with your audience.
Understanding Person Profiles
A person profile consists of:
- Reference images: Two photos showing different angles and expressions
- Description: Detailed written characteristics including age, physical features, and important details
The combination of images and description tells the AI exactly who should appear in your thumbnails.
Creating Your Person Profile
Step 1: Gather Two Reference Images
You need two different photos of the same person for best results.
Image 1: Primary Photo
- Clear frontal or near-frontal face shot
- Good lighting showing facial features clearly
- Natural expression or subtle emotion
- Face should be 60-80% of the image
Image 2: Secondary Photo
- Different angle (slightly rotated, different pose)
- Different lighting if possible
- Different expression than Image 1
- Captures facial features from alternative perspective
Why two images? Two different angles help the AI build a more complete, consistent understanding of your face across various expressions and poses.
Step 2: Crop to Just the Face
The most important rule: Capture only the face, no clothing.
Good: Just the face with some neck, clear facial features visible
Bad: Full body, upper torso, clothing, or background visible
The AI needs to focus on facial characteristics, not clothing or context. Crop both images tightly around the face and neck.
Step 3: Write Your Description
The description field is critical. This text guide helps the AI recreate your face accurately.
Writing Effective Descriptions
Your description should include:
Physical Characteristics
- Age: Actual or apparent age (e.g., "early 30s", "late 20s")
- Skin tone: Descriptive (e.g., "medium skin tone", "fair complexion")
- Face shape: (e.g., "oval face", "square jawline", "round face")
- Hair: Length, color, style, texture (e.g., "shoulder-length dark brown wavy hair", "short black straight hair")
Facial Features
- Eyes: Color, shape, size (e.g., "brown almond-shaped eyes", "blue round eyes")
- Nose: Shape and size (e.g., "straight medium nose", "prominent nose")
- Mouth: Lips and smile characteristics (e.g., "full lips", "thin lips", "natural smile")
- Eyebrows: Shape and color (e.g., "dark arched eyebrows", "light straight brows")
- Other distinguishing features: Beard, freckles, moles, scars, or unique characteristics (e.g., "light facial hair", "freckles across nose")
Important Negatives
Tell the AI what NOT to include:
- "No glasses or contacts"
- "No facial hair" or "light stubble only"
- "No visible tattoos on face or neck"
- "No hats or head coverings"
- "Smile should be subtle, not exaggerated"
Example Description
Early 30s male. Medium skin tone. Oval face shape.
Dark brown curly hair, shoulder-length.
Brown almond-shaped eyes, warm expression.
Straight nose, medium size.
Full lips, natural smile.
Light stubble on chin and cheeks.
No glasses. Keep facial hair minimal but present.
Friendly, approachable appearance.
What to Avoid When Creating Profiles
Avoid Hands in Images
Bad: Photos showing hands near face or hands visible
Good: Just the face and neck
Hands distract the AI and create inconsistency in generation.
Avoid Inconsistent Styles
Bad: One professional photo, one casual photo with very different appearance
Good: Two photos of the same person in similar settings, different angles/expressions
Consistency in lighting and setting between your two images helps the AI.
Avoid Backgrounds and Extra Elements
Bad: Busy background, multiple people, clothing visible
Good: Face and neck only, plain or blurred background
Extra elements create confusion about what defines your person.
Avoid Conflicting Descriptions
Bad: Description says "youthful 20s" but photos show someone older
Good: Match your description to what's visible in your photos
The AI needs consistency between images and text.
Avoid Overly Specific Styling
Bad: "Always wear red lipstick" or "Always in professional outfit"
Good: "Natural makeup" or "Various expressions"
Your person should work with different styles and prompts, not be locked into one look.
Using Your Person Profile
Once created, your person profile is available for every thumbnail generation:
- Select your person when starting a new thumbnail
- Use the same person across all your thumbnails for consistency
- Update only if needed (major appearance changes, new look)
Refining Your Person Profile
When to Update Your Profile
- Major appearance change (significant haircut, color change, weight change)
- Different life stage (aging over years, professional transformation)
- Consistency issues appearing in generated thumbnails
When NOT to Update
- Minor styling changes (different makeup, hair styling)
- Different expressions (your person profile handles this)
- Different emotions in thumbnails (that's what your prompt does)
Person Profile Checklist
Before finalizing your person profile, verify:
Images:
- Two high-quality photos of the same person
- Both photos show only face and neck, no clothing
- Different angles or lighting between the two
- Different expressions between the two
- Clear, well-lit, in-focus facial features
- No distracting hands, glasses, or backgrounds
Description:
- Age and general appearance
- All major facial features described (eyes, nose, mouth, face shape)
- Hair description (length, color, style)
- Skin tone specified
- Any distinguishing features noted
- Important negatives listed (no glasses, no hats, etc.)
- Tone is accurate and matches images
- No contradictions between images and text
Multiple People Profiles
Some creators maintain multiple person profiles:
- Different looks for different series
- Different emotional presentation
- Team members or collaborators
- Evolution of your appearance over time
However, for most creators, one consistent person profile builds better audience recognition.
Troubleshooting Person Profile Issues
"The person in my thumbnail doesn't look like me"
Solution 1: Verify your reference images clearly show your face
Solution 2: Review your description for accuracy and detail
Solution 3: Update with better quality reference photos
Solution 4: Add more specific distinguishing features to your description
"The AI is inconsistent with my appearance across thumbnails"
Solution: Your description might be too vague. Add more specific details about:
- Exact eye color and shape
- Exact hair color and length
- Distinctive features (freckles, marks, facial hair)
- Face shape and proportions
"The person looks too different in each generation"
Solution 1: Review your description for clarity and detail
Solution 2: Consider updating with better reference images
Solution 3: Use Edit mode when appearance varies too much
Solution 4: Add constraints in your prompt ("same recognizable face as usual")
