## What it does

The skill runs `crv` (claude-real-video) to inspect videos without burning context on redundant frames. Instead of fixed-interval captures, it uses scene-change detection alongside a sliding-window deduplicator. Passing `--grid` packs frames into 3x3 contact sheets, cutting image counts by roughly nine times.

Results land in `crv-out/` with a `MANIFEST.txt` summary, keyframe images, and transcribed text. The tool halts immediately if `ffmpeg` and `ffprobe` are missing from PATH. Speech transcription strictly requires `pip install "claude-real-video[whisper]"`, as the core package only extracts images.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add HUANGCHIHHUNGLeo/claude-real-video --skill claude-real-video-for-agents -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/claude-real-video-for-agents/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/claude-real-video-for-agents/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add HUANGCHIHHUNGLeo/claude-real-video --skill claude-real-video-for-agents -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/claude-real-video-for-agents/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add HUANGCHIHHUNGLeo/claude-real-video --skill claude-real-video-for-agents -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/claude-real-video-for-agents/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install HUANGCHIHHUNGLeo/claude-real-video claude-real-video-for-agents
```

2. **Manually: put the files in place**
- File: `.github/skills/claude-real-video-for-agents/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add HUANGCHIHHUNGLeo/claude-real-video --skill claude-real-video-for-agents -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/HUANGCHIHHUNGLeo/claude-real-video --path skills/claude-real-video-for-agents
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/claude-real-video-for-agents/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add HUANGCHIHHUNGLeo/claude-real-video --skill claude-real-video-for-agents -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/HUANGCHIHHUNGLeo/claude-real-video/tree/HEAD/skills/claude-real-video-for-agents/SKILL.md

## When to use it
- extract non-duplicate keyframes from video files
- tile consecutive frames into 3x3 grids to minimize tokens
- transcribe speech using Whisper with timestamp cues
- focus agent video inspection using target intent questions

## Example prompts
- Analyze lecture.mp4 with --grid and summarize the main points.
- Inspect tutorial.mp4 with crv using --why "find database credentials".
- Extract keyframes from demo.mp4 with --no-transcribe.

# claude-real-video for AI agents

## What is crv?

`crv` (claude-real-video) is a CLI tool that extracts meaningful frames and transcripts from videos so AI agents can "see" and "read" them. It uses scene-change detection (not fixed-interval sampling), sliding-window deduplication, and optional Whisper transcription.

**Key advantage**: Same 58-second clip at fixed 1fps = 58 frames. crv keeps the **26 that actually differ**, and `--grid` packs them into **3 contact sheets**. Fewer tokens, nothing missed.

## Installation

### Prerequisites

- Python 3.10+
- ffmpeg / ffprobe on PATH

```bash
# macOS
brew install ffmpeg

# Linux
sudo apt install ffmpeg

# Windows
winget install Gyan.FFmpeg
```

### Install crv

```bash
# Recommended: with audio transcription support
pip install "claude-real-video[whisper]"

# Core only (frames + dedup)
pip install claude-real-video
```

The `[whisper]` extra never installs itself — without it there is **no speech-to-text**
(videos that ship their own subtitles still get a transcript).

### Verify installation

```bash
crv --help
ffmpeg -version
```

### Install as agent skill

Run the bundled installer to symlink this skill into all detected agent platforms:

```bash
bash install-skill.sh
```

Or manually copy to your agent's skill directory:

```bash
# Claude Code
cp -r skills/claude-real-video-for-agents ~/.claude/skills/

# Codex
cp -r skills/claude-real-video-for-agents ~/.codex/skills/

# OpenCode
cp -r skills/claude-real-video-for-agents ~/.opencode/skills/

# Gemini CLI
cp -r skills/claude-real-video-for-agents ~/.gemini/skills/
```

## Usage

### Basic: Watch a video from URL

```bash
crv "https://www.youtube.com/watch?v=VIDEO_ID"
```

Output in `crv-out/`:
- `frames/` — deduplicated keyframes
- `transcript.txt` — plain-text transcript
- `MANIFEST.txt` — summary for LLM consumption

### Recommended: With grid and intent

```bash
crv "https://youtu.be/VIDEO_ID" -o crv-out --grid --why "what the user wants to know"
```

- `--grid` — tiles frames into 3x3 contact sheets (cuts image count ~9x)
- `--why` — focuses the analysis on a specific question

### Local file with transcript

```bash
crv lecture.mp4 -o out --lang en
```

### Frames only (no transcription — much faster)

```bash
crv clip.mp4 --no-transcribe
```

### Login-gated video

```bash
crv "https://..." --cookies cookies.txt
crv "https://..." --cookies-from-browser chrome
```

### Slow-changing content (animations, tutorials)

```bash
crv tutorial.mp4 --adaptive
```
