What problem does it solve? Video creators struggle to design thumbnails that both grab clicks and maintain a recognizable account identity across Bilibili, YouTube, Xiaohongshu, and WeChat Channels. This Skill defines the cover's information hierarchy, hook copy, platform aspect ratio, and brand-consistent layout genes before routing actual image generation to other tools. ## Core Features & Use Cases - Platform Ratio Presets: Provides correct dimensions for Bilibili (16:10), YouTube (16:9), Xiaohongshu (3:4), vertical video (9:16), and WeChat article headers (2.35:1). - Family Visual Identity: Keeps fixed brand elements (colors, fonts, logo position) while redesigning layout per video, so covers are recognizable without being templated. - Hook Copywriting: Generates short 3-6 character punchy cover titles distinct from the video title, optimized for thumbnail readability at 200px width. - Use Case: A creator finishing a talking-head video for Bilibili provides the topic and a frame screenshot, and receives a 1280x800 cover design spec with headline placement, accent color, and hook text ready for image generation. ## Quick Start Ask the AI to design a Bilibili cover for your video topic, providing the title and an optional screenshot from the footage.
