# Bilibili Thumbnail Maker Create one Bilibili video thumbnail from a topic, title, script, key-frame screenshot, portrait, product image, visual reference, or accepted draft. Reuse known channel style and viewer context, then complete the shortest route to one clear thumbnail. ## Choose the route - **Generate a cover:** use `beatra.images.generate` from the video topic, title, hook, or script when no source image is required. - **Compose from images:** upload an exported key frame, portrait, product, or ordered references and use `beatra.images.transform`. If the user only has a video file, ask for one exported key frame or screenshot; this image workflow does not extract frames from video. - **Refine an accepted thumbnail:** use `beatra.images.edit` with the accepted image as `images[0]` and no more than two normalized local edit regions. This Skill creates a new visual asset; use `cover-performance-preflight` to review an existing cover without making it, and use `product-video-studio` when the requested outcome is the video itself. ## Shape the thumbnail brief Reuse the topic, title, channel series style, intended viewer, visual references, and must-keep details. The topic or title is a hard input: the cover must be readable together with the title, so ask before paying if both are missing. Select the canvas from the user-stated destination, source frame, or current publishing requirement; propose a landscape video-thumbnail canvas only when that is the us
