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

# 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.

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