short-video-cover

根据视频口播文案,为视频号/抖音/小红书短视频生成 3:4 竖版封面图。当用户需要给短视频做封面、配缩略图、出竖版题图时使用。触发词包括:做视频封面、生成视频封面图、视频号封面、抖音封面、小红书视频封面、竖版封面、3:4 封面、短视频题图。即使用户只是说"帮我给这个视频做个封面"或"封面还没做",只要上下文涉及短视频发布,都应该触发。通过 ai-image-generator 的 edit 模式生成(默认 MuleRun Nano Banana 2, 也可切换 APImart/Atlas/Agnes),以主持人参考图为参考图,提供 11 种可选视觉风格(默认深色科技标题风),产出符合短视频平台爆款规律的竖版封面图。不要用于公众号宽幅题图(2.35:1)、朋友圈九宫格、头像、海报等非 3:4 短视频封面场景；本 skill 只处理 3:4 竖版短视频封面。
