Video Summarizer

Analyzes MP4 files in a directory via the Gemini API and writes a .md summary file next to each video.

Prerequisites

• GEMINI_API_KEY env var must be set
• google-genai installed: py -m pip install google-genai
• Python available as py (Windows) or python3

Workflow

1. Determine the prompt

Check if the user provided a custom prompt or specific extraction instructions.

• No custom prompt -> use the default (structured summary with Title, Summary, Key Points, Takeaways)
• User provides custom instructions -> pass them via --prompt or --prompt-file
