AI Auto-Placement Tips and Precautions

Tips to Increase Effectiveness

1. Specific Prompts

Bad Example:
"Cooking thumbnail"

Good Example:
"Korean cooking recipe thumbnail,
completed food photo center,
text: '5-Minute Kimchi Stew',
warm and appetizing atmosphere,
red and orange color tone"

2. Repetitive Style Learning

For same channel:
- Save previously successful layout
- Add to Canva "Brand Kit"
- Magic Design learns brand style
→ Consistent results

3. A/B Testing

Among multiple options AI generated:
- Select top 2-3
- Actually apply each to video
- Compare click-through rates
- Identify most effective style

Precautions

❌ Don't Blindly Trust AI

AI results also need review:
- Check if text is cut off
- Check if color harmony is awkward
- Check if visible on mobile too

❌ Don't Request Too Many Elements

Too many elements in prompt:
"5 texts, 3 images, 10 icons..."
→ AI generates complex and chaotic layout

Appropriate Elements:
- Text 2-3
- Images 1-2
- Icons 1-3

❌ Don't Ignore Brand Consistency

Generating different styles every time:
- Weakens channel identity
- Confuses subscribers

Solution:
- Decide basic layout template
- Only change colors, fonts
- Maintain consistency

Layout Comparison Analysis with ChatGPT

My Input:

[Layout A Screenshot]
[Layout B Screenshot]

Analyze which of these two thumbnails would be more effective,
and tell me strengths and weaknesses of each.

Topic: "Beginner Yoga Routine"
Target: Women in their 30s-40s

ChatGPT's Response Example:

Analysis Result:

Layout A (Left-Right Split):
Strengths:
✓ Text and image clearly separated
✓ Information delivery is clean
✓ Professional and trustworthy

Weaknesses:
✗ Somewhat static and stiff
✗ Weak emotional connection
✗ May be slightly cold for target age group

Expected Click-Through Rate: 6.2%

---

Layout B (Center Focus):
Strengths:
✓ Yoga pose shown large for visual impact
✓ Warm color tone friendly to target
✓ Feels like "I can do this too"

Weaknesses:
✗ Text relatively small
✗ Emotion prioritized over information delivery

Expected Click-Through Rate: 7.8%

Recommendation: Layout B
Reasons:
- Women in 30s-40s prefer emotional communication
- Yoga needs visual expression
- "Can do it" feeling induces clicks
- Warmer and more beginner-friendly

Improvement Suggestion:
Enlarging Layout B's text by 15% would be perfect!
