video-understand은(는) 무엇을 하나요?
ffmpeg 프레임 추출 및 Whisper 전사를 사용하여 비디오 콘텐츠를 로컬에서 이해합니다. API 키가 필요 없습니다. 사용 시기: (1) 비디오에 포함된 내용 파악, (2) 로컬에서 비디오 오디오 전사, (3) 시각 분석용 키 프레임 추출, (4) API 키 없이 비디오 콘텐츠 획득.
로컬에서 ffmpeg 프레임 추출 및 Whisper 전사를 사용하여 비디오 콘텐츠를 이해합니다. API 키가 필요 없습니다. (1) 비디오 내용 파악, (2) 로컬 오디오 전사, (3) 시각 분석용 키 프레임 추출, (4) API 키 없이 비디오 콘텐츠 획득 시 사용합니다.
이 스킬은 로컬 환경에서 비디오 콘텐츠를 분석하고 이해할 수 있도록 설계된 에이전트 도구입니다. ffmpeg을 활용하여 비디오에서 프레임과 오디오를 추출하고, OpenAI Whisper 모델을 사용하여 오디오를 텍스트로 전사합니다. API 키나 외부 서비스에 의존하지 않으므로 오프라인 환경이나 개인정보 보호가 중요한 상황에서도 안전하게 사용할 수 있습니다. 주요 사용 사례로는 비디오의 시각적 내용 파악, 음성 전사, 키 프레임 추출을 통한 요약 등이 있으며, 다양한 AI 에이전트 플랫폼에서 활용 가능합니다.

This repo contains 9 individual skills — each has its own dedicated page.
Generate AI videos from text prompts using the HeyGen API. Use when: (1) Generating videos from text descriptions, (2) Creating AI-generated video clips for content production, (3) Image-to-video generation with a reference image, (4) Choosing between video generation providers (VEO, Kling, Sora, Runway, Seedance), (5) Working with HeyGen's /v1/workflows/executions endpoint for video generation.
Create AI avatar videos with precise control over avatars, voices, scripts, and backgrounds using HeyGen's v3 API (POST /v3/videos). Two modes: type="avatar" with avatar_id, or type="image" with an image AssetInput (Avatar IV). Use when: (1) Choosing a specific avatar and voice for a video, (2) Writing exact scripts for an avatar to speak, (3) Animating a photo into a speaking video (type="image"), (4) Transparent background videos with remove_background, (5) Integrating HeyGen avatars with Remotion, (6) Batch video generation with exact specs, (7) Brand-consistent production videos with precise control.
Create videos from a text prompt using HeyGen's Video Agent (POST /v3/video-agents). The default for most video requests — AI handles script, avatar, visuals, voiceover, and captions automatically. Use when: (1) Creating a video from a description or idea, (2) Generating explainer, demo, or marketing videos from a prompt, (3) Making a video without specifying exact avatars, voices, or scenes, (4) Quick video prototyping or drafts, (5) User says "make me a video" or "create a video about X". For precise control over specific avatars, exact scripts, or per-scene configuration, use the avatar-video skill instead.
Swap faces in a video using AI via the HeyGen API. Use when: (1) Replacing a face in a video with another face, (2) Face swapping from a source image onto a target video, (3) Creating personalized videos by swapping in a person's face, (4) Working with HeyGen's /v1/workflows/executions endpoint for face swap processing.
[DEPRECATED] Use `create-video` for prompt-based video generation or `avatar-video` for precise avatar/scene control. This legacy skill combines both workflows — the newer focused skills provide clearer guidance.
Generate HeyGen presenter videos via the v3 Video Agent pipeline — handles Frame Check (aspect ratio correction), prompt engineering, avatar resolution, and voice selection. Required for any HeyGen video generation. Replaces deprecated endpoints with v3. Use when: (1) generating any HeyGen video (via API or otherwise), (2) sending a personalized video message (outreach, update, announcement, pitch, knowledge), (3) creating a HeyGen presenter-led explainer, tutorial, or product demo with a human face, (4) "make a video of me saying...", "send a video to my leads", "record an update for my team", "create a video pitch", "make a loom-style message", "I want to appear in this video", "generate a HeyGen video", "make a talking head video". Accepts avatar_id from heygen-avatar for identity-first HeyGen videos, or uses a stock presenter. Returns video share URL + HeyGen session URL for iteration. Chain signal: when the user wants to create/design an avatar AND make a video in the same request, run heygen-avatar firs
Download video and audio from YouTube and 1000+ sites using yt-dlp. No API keys needed. Use when: (1) Downloading a video from YouTube or other sites, (2) Extracting audio from a video URL, (3) Downloading subtitles/captions from a video, (4) Getting video metadata without downloading.
Translate and dub existing videos into multiple languages using HeyGen.
Create, extract, and apply portable visual design systems via visual-style.md files. Use when: (1) Creating a visual-style.md design system from scratch, (2) Extracting a visual style from a website URL, video, or PDF brand guide, (3) Applying a visual style to HeyGen videos, HTML slides, Figma, or paper.design, (4) Browsing the gallery of pre-built visual styles (Swiss, Saul Bass, Game Boy, etc.), (5) User mentions "visual style", "design system", "brand style", or "style guide", (6) Styling a HeyGen video with a consistent design language.

Agent skill repository discovered by 10x-chat research.
Review backend code for quality, security, maintainability, and best practices based on established checklist rules. Use when the user requests a review, analysis, or improvement of backend files (e.g., `.py`) under the `api/` directory. Do NOT use for frontend files (e.g., `.tsx`, `.ts`, `.js`). Supports pending-change review, code snippets review, and file-focused review.
