# Video Understanding (Gemini)
Analyze videos using Google Gemini's multimodal video understanding. Supports 1000+ video sources via yt-dlp.
## Requirements
- `yt-dlp` — `brew install yt-dlp` / `pip install yt-dlp`
- `ffmpeg` — `brew install ffmpeg` (for merging video+audio streams)
- `GEMINI_API_KEY` environment variable
## Default Output
Returns structured JSON:
- **transcript** — Verbatim transcript with `[MM:SS]` timestamps
- **description** — Visual description (people, setting, UI, text on screen, flow)
- **summary** — 2-3 sentence summary
- **duration_seconds** — Estimated duration
- **speakers** — Identified speakers
## Usage
### Analyze a video (structured JSON output)
```bash
uv run {baseDir}/scripts/analyze_video.py "<video-url>"
```
### Ask a question (adds "answer" field)
```bash
uv run {baseDir}/scripts/analyze_video.py "<video-url>" -q "What product is shown?"
```
### Override prompt entirely
```bash
uv run {baseDir}/scripts/analyze_video.py "<video-url>" -p "Custom prompt" --raw
```
### Download only (no analysis)
```bash
uv run {baseDir}/scripts/analyze_video.py "<video-url>" --download-only -o video.mp4
```
## Options
| Flag | Description | Default |
|------|-------------|---------|
| `-q` / `--question` | Question to answer (added to default fields) | none |
| `-p` / `--prompt` | Override entire prompt (ignores -q) | structured JSON |
| `-m` / `--model` | Gemini model | gemini-2.5-flash |
| `-o` / `--output` | Save output to file | stdout |
| `--keep` | Keep downloaded video file | false |
| `--download-only` | Download only, skip analysis | false |
| `--max-size` | Max file size in MB | 500 |
| `--raw` | Raw text output instead of JSON | false |
## How It Works
1. **YouTube URLs** → Passed directly to Gemini (no download needed)
2. **All other URLs** → Downloaded via yt-dlp → uploaded to Gemini File API → poll until processed
3. Gemini analyzes video with structured prompt → returns JSON
4. Temp files and Gemini uploads cleaned...
