remotion-4k-video

把一个网页版 deck(Vite+React+TS,通常由 web-video-presentation skill 产出,如 audiobooks/<id>/presentation/)用 Remotion 帧级重渲成「颜色不失真」的 4K MP4,并可选垫入很轻的 BGM。解决录屏的两大痛点:①录屏颜色失真 → Remotion 输出 sRGB 保真;②手动录屏节奏不稳 → 帧精确、音画锁定。**核心铁律:Remotion 不渲染 CSS animation/transition(逐帧渲染时页面时钟冻结,内容会在第0帧直接定格到最终态 → 表现为「太快/没渐变」);所有入场动画必须用 useCurrentFrame()+interpolate()/spring() 帧驱动**,本 skill 提供可复用的动画原语库(useReveal/useStamp/useProgress/useDraw)与转换套路。时长 = 每步音频长度 + 120ms trail(与网页版 audio.onended+trailMs 一致,由 gen_timeline.py 从 mp3 实测生成)。触发场景:把有声书/演示 deck 渲成 4K 视频、"Remotion 视频太快/没有渐变/动画不播/颜色对但节奏不对"、给已渲染视频加淡淡的背景音乐压噪底。本项目实样:audiobooks/sanen/remotion/。
