🎭 Face-Focused Thumbnails
We tested how well different AI tools handle thumbnails where a person’s face is the focal point — a crucial case for creator-centric, testimonial, or tutorial content. Accuracy in face rendering, placement, and emotional expression were key evaluation criteria.
Input:
Generate a YouTube thumbnail in 16:9 ratio.
Use the exact text provided below.
Include the uploaded image, which is a [type: face image].
What We Found:
- Canva: Handled faces reasonably well. Expression and placement matched the theme; background tweaks and extra text editing were easy within Canva’s interface.
- VidIQ: Best performance overall. Face images were clearly visible and correctly placed. It maintained layout structure, adhered to prompts, and even balanced other design elements around the face.
- Copilot: Strong prompt adherence, but the face image used was off — altered expression and different alignment reduced emotional impact.
- ChatGPT: Face was present but didn’t match the original well — slight changes in expression and layout disrupted authenticity. No post-generation editing makes it hard to fix.
