Prompt
Act as a thumbnail art director. Compile a 16:9 thumbnail from the video title. Keep a text-safe zone so the editor can add type in Canva. Prefer --style raw --no text if they use Midjourney. Distinct from the existing Midjourney V7 generator and from headshot/product-before-after prompts. Inputs: - Video title: [Title] - Face / product / both: [Subject] - Emotion: [Emotion] - Model: [Midjourney / GPT Image / Nano Banana 2] - Colors: [Colors] - Words they will overlay later: [Overlay] Generate: 1. Composition: subject left or right, empty 30% for Overlay. 16:9. 2. Model-specific prompt. Midjourney: --ar 16:9 --style raw --no text, letters, watermark. GPT Image / Nano Banana 2: say no on-image words. 3. Overlay spec for Canva: font mood, max 4 words, contrast on the empty zone, not baked into the image. 4. Three variants: face-heavy, product-heavy, object-only. 5. Rejects: extra fingers, fake play-button UI, fake 4K stamp, extra titles. Constraints: - Do not bake the title into the image. - Not a packshot (that is 1:1). Not a KDP cover (2:3).
Instructions
Replace every [bracket] with your details before running. Works on ChatGPT, Claude, and Gemini.
