steipete
video-editing
AI-assisted video editing workflows for cutting, structuring, and augmenting real footage. Covers the full pipeline from raw capture through FFmpeg, Remotion, ElevenLabs, fal.ai, and final polish in Descript or CapCut. Use when the user wants to edit video, cut footage, create vlogs, or build video content.
affaan-m
gsap
GSAP animation reference for HyperFrames. Covers gsap.to(), from(), fromTo(), easing, stagger, defaults, timelines (gsap.timeline(), position parameter, labels, nesting, playback), and performance (transforms, will-change, quickTo). Use when writing GSAP animations in HyperFrames compositions.
heygen-comwebsite-to-hyperframes
Capture a website and create a HyperFrames video from it. Use when: (1) a user provides a URL and wants a video, (2) someone says \"capture this site\", \"turn this into a video\", \"make a promo from my site\", (3) the user wants a social ad, product tour, or any video based on an existing website, (4) the user shares a link and asks for any kind of video content. Even if the user just pastes a URL — this is the skill to use.
heygen-comcaptions-overlay
Overlay doctrine for the embedded-captions workflow — the caption MODEL (drop / rail / embed) and the rule that captions are an OVERLAY composited on top of the film, never a reserved bottom band you shift content up to avoid. Load when adding captions/subtitles to a talking-head or launch video, when deciding whether a phrase should be dropped, ride the verbatim rail, or be promoted to a scarce embedded climax, when laying out a composition that will carry captions (do NOT reserve a keep-out band), or when centering a composition on the true frame center under captions. Quotes the rail+embed model from embedded-captions and constraint #13 (captions overlay, keep-out band retired) from the product-launch-video scene agent. Applies ON TOP of embedded-captions.
heygen-commotion-doctrine
GATEWAY — load FIRST before composing any HyperFrames animation or video. The high-level motion law that makes a multi-scene video feel like ONE continuous camera move instead of a stack of independently-animated slides. Covers the vector law (how you exit determines how you enter, incl. the Z scale-sign rule), the film's current, carrier elements, causal motion, the Seam Gate (build-gate enforcement), the ban on idle wobble (motion must PERFORM, not breathe), stillness-before-climax, and the sustained-motion routes. Routes to the low-level technique skills (cut-the-curve — the full catalog incl. waterfall entry + nudge curve, oversized-cursor, seam-craft). These rules SUPERSEDE generic / upstream motion guidance. [continuity, direction, vector, momentum, seam, transition, ease, performance, idle-motion, narrative-motion, film-grammar]
heygen-comcut-the-curve
The technique catalog: five velocity-matched SEAMS (zoom-through, INVERSE zoom-through, cut-the-curve, waterfall cut, rack-focus blur-cut) plus the two in-scene techniques — waterfall ENTRY (staggered arrival cascades for title cards / segment openers) and the nudge curve (slow-fast-slow three-phase group slides). Covers partial-travel (~12% of frame) velocity matching via mirrored power4 eases, the Z scale-sign rule, size-scaled blur (10px text / 18-20px full-frame), word-by-word staggered cuts, cascade pacing by element weight, and the 10/65/25 slide ratio. Read before authoring any transition, text-beat handoff, kinetic text entry, or group reposition. [depth, zoom, inverse-zoom, scale-sign, mirrored-zoom, rack-focus, pacing, velocity, cut-the-curve, waterfall, stagger, cascade, kinetic-text, title-card, segment-opener, nudge, slide, easing, group-motion, z-depth, motion-graphics, cinematic, transition, blur, directional-continuity]
heygen-comchangelog-video
Turn a weekly changelog .md into a finished branded changelog video (square 1080, ~45-60s, Annie VO, animated brand background, mock-UI visualizations, lowkey captions). Use when the user provides a changelog/digest markdown and wants the weekly video, or says "changelog video". Self-contained — fonts, background, lexicon, and scripts ship in this skill.
heygen-comseam-craft
Render-correctness doctrine for scene-to-scene seams in HyperFrames launch videos — the prerequisites that make transitions composite correctly on the master timeline. Load when assembling the master timeline / index.html, when a white flash appears at a cut or crossfade seam (especially on dark films), when reasoning about why a transition opacity dip shows through, or when verifying the render-side mechanics of how overlapping scene wrappers blend. Covers the opaque stage-ground (#root background) white-flash guard and how the injector overlaps wrappers, holds final frames, ping-pongs tracks, and stamps lint-clean template code onto the master timeline. Does NOT contain the per-transition catalog — see the transition registry for individual transition entries.
heygen-comoversized-cursor
House-style oversized macOS cursor technique for HyperFrames launch videos. Load whenever a scene involves cursors or a pointer-led action, when kicking off a UI scene, when igniting a morph/transition/typing run with a click, or when a scene reads as static, dead, or stale and needs a cheap high-yield source of motion to carry the viewer's eye and segment them out of the stale state. Covers cursor size/look (incl. brand-motif cursors), the off-screen entry law, tip-targeting and the click tap, click-ignites-the-next-beat, and exit / cross-scene handoff.
heygen-comhyperframes-keyframes
当 HyperFrames 合成需要可搜索的 2D/3D 关键帧、GSAP 时间线、CSS 关键帧、Anime.js、WAAPI、FLIP、路径、蒙版、SVG 变形/绘制、文本轨迹、3D 深度或 `hyperframes keyframes` 诊断时使用。不要用于广泛的场景策略、品牌设计、媒体来源、字幕或一般视频规划。
heygen-comfigma
将 Figma 内容导入 HyperFrames 合成——渲染资源、品牌令牌、组件、故事板章节 → 重构动画（帧作为状态读取，而非幻灯片）（REST/CLI）、Figma Motion 动画（MCP）和着色器（MCP 源/原生导出）。当用户粘贴 figma.com 链接或要求将 Figma 设计、画框、Logo、品牌或动画导入视频/合成时使用。
heygen-commusic-to-video
当用户提供音乐曲目（音频文件或需要提取音频的视频）并希望生成与节拍同步的 HyperFrames 视频时使用，风格从平静到强烈均可。音乐驱动一切：一个分析器一次性读取音乐，编排器布局帧并填充每帧计划，一个子代理构建每帧。排版和模板是基础——完整视频无需任何素材——但用户提供的任何图片或视频都会在同一节拍网格上（节拍剪辑/肯·伯恩斯效果）切入帧中。类型（歌词视频、幻灯片、动态宣传片）由每帧的选择决定；流程从不分支。
heygen-comtalking-head-recut
Package an existing talking-head / interview / podcast video by layering timed, designed GRAPHIC OVERLAY cards onto the playing video — titles, lower-thirds, data callouts, quotes, side panels, picture-in-picture — synced to the transcript. The source video plays in full; the agent designs and writes each card's HTML in conversation, then renders to MP4 via hyperframes. Use when the user asks for graphic overlays, on-screen graphics / lower-thirds / data callouts / kinetic titles on a video, "package / dress up my video", "add overlay cards / graphic cards", or AI-composed graphic packaging of an existing video. NOT for plain subtitles (→ embedded-captions) or building a video from scratch (→ the creation workflows); when unsure overlays-vs-captions, see /hyperframes.

heygen-commotion-graphics
当用户想要一个简短、以设计为主导的动态图形时使用，其中运动本身就是信息：动态排版、统计数据或数字计数、图表/数据可视化展示、Logo 出场、品牌组合、下三分之一标题、标注、社交媒体叠加层、动画标题/推文/新闻条目、动态海报或快速捕获的页面高亮。通常时长在10秒以内，最长约30秒，没有叙事弧线、画外音或真人拍摄主体。可渲染为MP4或透明叠加层。不适用于较长、多场景、带旁白或品牌宣传片的作品（请使用 /general-video）、带旁白的网站视频（/website-to-video）、主题讲解（/faceless-explainer）、产品推广（/product-launch-video）、公关视频（pr-to-video）或为现有素材添加字幕（/embedded-captions）。如果不确定是快速动态优先的作品还是较长/带旁白的处理方式，请参阅 /hyperframes。
heygen-comhyperframes-creative
HyperFrames视频的非动画创意指导。用于设计规范（frame.md / design.md）处理、调色板、排版、旁白、节拍规划、音频响应式视觉、构图模式以及品牌/风格决策。对于原子运动模式和场景蓝图，请使用`hyperframes-animation`。
heygen-comgeneral-video
用于创作自定义 HyperFrames 视频合成（任意长度或格式）的通用工作流——适用于较长或多场景作品、品牌/精彩集锦、蒙太奇、标题卡片、静态循环及自由形式合成。与输入和长度无关。如果某个专门工作流明显适合输入（如已上市产品、网站、主题讲解、GitHub PR、现有素材、短动态图形或 Remotion 移植），则优先使用该工作流（参见 /hyperframes）；仅当无合适工作流时，才将此作为通用回退方案。
heygen-comwebsite-to-video
Capture a general website/URL and turn it into a HyperFrames video (site tour, showcase, or social clip from the site's own visuals). Uses headless Chrome screenshots + brand assets. Use when intent is general — portfolio/blog/landing-page showcase or social clip from the site. NOT for: product/SaaS launch or promo (→ /product-launch-video, even from a URL); topic explainer with no site (→ /faceless-explainer); GitHub PR (→ /pr-to-video); adding captions to existing video (→ /embedded-captions); short unnarrated page-highlight motion graphic (→ /motion-graphics). Unclear launch-vs-general-site? Ask one question or start at /hyperframes.
