Video & Animation

Use when audio already placed in a HyperFrames composition needs to be mixed: fade-in/fade-out, crossfade, track gain or volume, volume automation, ducking, a music bed that fights a voiceover (voiceover carve), effects on a track (EQ, compressor, limiter, gate, saturation, delay, reverb, chorus, phaser, bitcrush), automation envelopes drawn on a track's volume or any effect parameter, or one submix bus carrying a chain, a fader and an automation clock for several tracks at once (`<hf-audio-group>`). Don't use for sourcing or generating audio — finding BGM, SFX, or making a voiceover is `/media-use`. Don't use for clip timing or track layout, which is `/hyperframes-core`.

Guides Codex through research-led book short-video production, using Bookflow episode files and checks. Use when a creator wants to plan, produce, or review a book video with this repository.

用 yutto 下载 Bilibili 音频、用 yt-dlp 下载 YouTube 音频，再用 Qwen3-ASR 与 ForcedAligner 生成一份带时间戳的 SRT 并检查质量，可选 Whisper。用于 B 站或 YouTube 链接转字幕、继续转写已有音频；下载失败时优先检查对应下载包更新。

剪映字幕AI纠错流水线。当用户说"纠字幕"、"字幕纠错"、"改字幕"、"修正字幕"、"字幕识别错了"、"处理字幕"，或提到录完视频要在剪映里改专有名词字幕（如 Agent、Claude Code、MCP 识别错）时使用。流程：剪映智能字幕识别 → 本工具解密草稿 → 术语表规则+智谱glm-4-flash双层纠错 → 回加密写回 → 用户回剪映手动剪辑。

Edit video and audio with local FFmpeg from natural-language requests: cut, trim, join, resize/reframe (9:16, 1:1), speed change, captions and subtitles (SRT/ASS, animated, karaoke), logos and text overlays, lower-thirds and titles, silence removal, multicam and external-mic sync, loudness normalisation, HDR/Dolby Vision to SDR, LUTs, background music with ducking, platform exports (YouTube, Reels, TikTok, X), compliance checks, scene detection and highlight reels, contact sheets to inspect results, and whole-edit project files. Use this skill whenever the user mentions a video or audio file (mp4, mov, mkv, wav, m4a), footage, a clip, captions, subtitles, a reel or short, YouTube/Instagram/TikTok delivery, LUFS, sync, transcoding, ffmpeg, or asks to make something "60 seconds", "vertical", "louder", "captioned" — even when they do not say "edit". Python 3.9 standard library only, no cloud, no API keys.

High-performance native Rust fork of ffmpeg-skill. Deterministic FFmpeg media manipulation toolkit and Model Context Protocol (MCP) server for AI pair programmers and creators.

使用 Python Pycairo、Gemini 3.8 Flash TTS 與 FFmpeg 自動化生成高質感向量卡通導覽與教學解說短影片。當使用者提到「做影片」、「製作動畫」、「卡通影片」、「教學影片」、「短片製作」、「videokit」、「小半天影片」、「碳導遊」或需要從腳本、配音、角色繪製到最終 MP4 輸出的完整管線時使用。

Phân tích một video bằng Gemini ở chế độ agentic (AI tự quay lại xem đúng đoạn cần, không nuốt cả video). Đầu vào là file video trong máy hoặc link YouTube công khai. Dùng khi người dùng muốn tóm tắt video/bài giảng kèm mốc thời gian, cắt highlight, bắt lỗi trong bản ghi màn hình, tìm lúc nào xuất hiện một thứ, đếm vật/hành động, hoặc hỏi bất kỳ câu gì về nội dung một video.

Run a stateful, human-in-the-loop workflow for producing B2B English short-video packages. Use when a creator asks to research a topic, select and verify a source article, develop multiple 45–60 second English script angles, create a storyboard and stock-footage search terms, define a music direction, or generate title options. Pause at required human checkpoints and resume from a named step; never replace editorial approval, footage selection, editing, final music selection, or publishing.

Coordinate prompt-to-short-video discovery, scripting and production. Resume existing projects and route soundtrack or mix corrections directly to production. Preserve direction choice and script approval; exclude general audio advice.

>- Design and review a coherent visual system for short-form video before and during Remotion implementation. Use for video art direction, scene UI, typography, layout, color, diagrams, captions, motion, transitions, platform safe areas, or visual-quality review. Use Remotion skills separately for API, timeline, media, Studio, and rendering behavior; do not use this skill for narration-only or research-only work.

批量剪辑竖屏促销短视频(抖音/视频号,30 秒左右):实拍素材 + 活动"明白卡" → 按爆款模板自动写文案、剪映 SAMI 配音、选镜头、渲染 60fps 成片、自动质检,一条命令出 N 条内容各不相同的成片。用户说"批量剪视频/复刻爆款/按模板出片/照着这个视频剪 N 条/商场活动短视频/量产短视频"时使用。代码仓库在 E:/short-video-factory(GUI: app.py)。

Structure Remotion markup for interactivity

>- Run Phase 1 of the shared short-video workflow: turn a raw topic or prompt into a sourced research pack and 2–4 distinct video directions, each with a defensible tension hook, promise, payoff, beats, visual approach, duration range, and risks. Use whenever the user asks for video ideas, angles, research, facts, hooks, topic analysis, or choices before scriptwriting. Stop for the user's direction choice and do not silently continue into script or production.

Transcribing, displaying and animating captions

Remotion Map animation knowledge

Router for all Remotion skills

Generate, revise or troubleshoot local Kokoro narration, pronunciation and scene word timing. Reuse verified unchanged clips; inspect the Python environment before setup changes. Exclude research, visuals, music composition and publishing.

Content, animation and effects best practices

Produce an approved short video or correct an existing video's background sound, emotion, captions, mix or export. Generate only changed narration, render and review a current preview, run technical and editorial QC, then export. Exclude script-only and general audio-advice requests.

Upgrade Remotion, and related packages

>- Run Phase 2 of the shared short-video workflow: convert an explicitly selected direction and its research into a reviewable beat sheet, narration, flexible scene timing, on-screen text, visual plan, captions, music and SFX cues, pronunciation notes, payoff, takeaway, and contextual CTA. Use whenever a user asks to write, revise, preview, or approve a short-video script. Stop for script approval and do not generate TTS or render video yet.

Check a rendered video before anyone else sees it: format, black or frozen frames, loudness, true peak, and a frame sheet to look at. Use before submitting any animatic or final, and before `mfx step done` on a build.
