# Gemini Video Analyzer

Analyze videos natively using Google Gemini's multimodal API. No frame extraction needed — Gemini processes video at 1 FPS with full motion, audio, and visual understanding.

## Quick Start

```bash
# Analyze a video with default prompt (full description)
GOOGLE_AI_API_KEY=$GOOGLE_AI_API_KEY python3 {baseDir}/scripts/analyze.py /path/to/video.mp4

# Ask a specific question
GOOGLE_AI_API_KEY=$GOOGLE_AI_API_KEY python3 {baseDir}/scripts/analyze.py /path/to/video.mp4 "What text is visible on screen?"

# Manage uploaded files
GOOGLE_AI_API_KEY=$GOOGLE_AI_API_KEY python3 {baseDir}/scripts/manage_files.py list
GOOGLE_AI_API_KEY=$GOOGLE_AI_API_KEY python3 {baseDir}/scripts/manage_files.py cleanup
```

## Supported Formats

MP4, AVI, MOV, MKV, WebM, FLV, MPEG, MPG, WMV, 3GP — up to 2GB per file.

## How It Works

1. Video uploads to Google's Files API (temporary, auto-deletes after 48h)
2. Gemini processes at 1 frame/sec — understands motion, transitions, audio context
3. Model generates response based on your prompt
4. Way better than frame extraction for understanding temporal content

## Use Cases

| Task | Example Prompt |
|------|---------------|
| General description | *(default — no prompt needed)* |
| UI/text extraction | `"What text and UI elements are visible?"` |
| Tutorial summary | `"Summarize the steps shown in this tutorial"` |
| Bug report from video | `"Describe what went wrong in this screen recording"` |
| Meeting notes | `"Summarize the key points discussed"` |
| Content comparison | Upload 2 videos, ask for differences |

## Configuration

Set `GOOGLE_AI_API_KEY` in your environment or `.env` file. Get a free key at [aistudio.google.com](https://aistudio.google.com/apikey).

Default model: `gemini-2.5-flash` (fast, cheap, excellent vision). Override with `--model gemini-2.5-pro` for complex analysis.
