Story Announcement thumbnail style

Bold full-screen announcement — a drop, update or invite.

What this style looks like

When you pick the Story Announcement style in Thumby, the AI agent assembles every render around these visual rules — the same prompt scaffolding our system uses to build a CTR-tuned thumbnail in roughly 60 seconds:

bold full-screen announcement, energetic but clean, single unmistakable message

Color, lighting, and mood

vivid on-brand gradient or solid full-bleed background, punchy contrast, modern and confident

Composition rules

On top of the look itself, every render in this style follows these layout principles — tuned to keep the thumbnail readable at mobile-feed size and to maximise CTR on YouTube’s 2026 algorithm:

one short headline set large and vertically centred over a full-bleed background, message kept clear of the very top and bottom

Who this style is for

Pick the Story Announcementstyle when your video lives in the niche this look was tuned for. Most users pair it with a one-line topic — the AI agent writes the full prompt, applies the style on top, and ships a 16:9 thumbnail you can download or upscale to 2K / 4K straight away. If you’ve got a face or product photo to anchor the render, drop it in as a reference and the style renders your subject in the look above instead of a generic stock figure.
