Prompt
Background image for a YouTube thumbnail in horizontal 16:9 format, with no text and no people. Video topic: {{topic}}. Scene: {{scene}}, shown in a highly visual way that can be understood in one second, with a single large, clear hero object. Composition built for a thumbnail: the main element on the {{object_side}} third, the opposite third left clear for a cut-out photo of a person, and the top strip empty for a two- or three-word title. {{color_style}} colors, very high contrast between the background and the hero object, a bright rim light separating it from the background, soft vignetting at the edges. Slightly blurred background with depth. Strong sharpness and details that stay readable even at small sizes, vibrant digital photography style.How to use it
- Sum up the video in a single image: the object, result or problem that explains it all.
- Place your cut-out photo and the title in an editor; the final thumbnail should be 1280 × 720 pixels.
- Look at it at small size, as on a phone: if it does not read in one second, simplify.
Usage example
Topic: how to cut your electric bill · Scene: a giant glowing light bulb above a stack of coins · Side: right · Colors: saturated yellow and blue.
