Create a Bilibili video cover or Bilibili thumbnail from a topic, title, script, key frame, portrait, product photo, or reference image. This AI thumbnail maker builds a strong focal visual, readable hierarchy, and headline-safe space for Bilibili creators, explainers, tech reviews, lifestyle vlogs, games, food, and entertainment videos, then refines an accepted draft into a repeatable channel look.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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`.

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 …

How to install
mdr add beatra-ai/beatra-skills/bilibili-thumbnail-maker@sha256:b06748da7c7a20ebThe line at the top of this page pins the label git:20261015.2337206, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
