The prompt

69 words · 457 characters

YouTube thumbnail image, close-up of a young South Asian male explorer with a headlamp on the left third of the frame, wide-eyed amazed expression with mouth open, pointing toward a massive glowing turquoise crystal cave on the right, extreme contrast, saturated colors, bright rim light on his face, dark vignette edges, sharp subject separation, simple uncluttered background, bold composition readable at small size, empty space top-right for title text.

Flux follows plain descriptive language closely. Set the aspect ratio in your app's size setting; negative prompts are not needed.

Tips to get more from it

  • Add your title text in an editor rather than in-prompt for perfect legibility.
  • Test the thumbnail at 160px wide; if the face isn't readable, crop tighter.
  • Swap the cave for an abandoned temple or deep ocean to fit your video topic.

Questions about this prompt

Which AI model is this youtube thumbnail prompt written for?

It was written and tested for Flux, but the format buttons above rewrite it for Midjourney, Stable Diffusion, DALL·E, Flux, Ideogram and Leonardo, so you can paste it into the tool you already use.

Can I change the aspect ratio or style?

Yes. The prompt is set for 16:9, which suits this composition. In Midjourney change the --ar value; in other apps pick the size in settings. Use the remix panel to swap the style, lighting, camera or mood without rewriting the whole prompt.

Is this prompt free to use for commercial work?

The prompt text is free to copy, edit and use. Whether you can sell the image depends on the terms of the AI model that generates it, so check your plan on that platform before using results commercially.
