Markdown and PowerPoint to Narration Video Generator.

slidemovie is a Python tool that automates the creation of professional narration videos. By combining the structural simplicity of Markdown, the design capabilities of PowerPoint, and the power of AI Text-to-Speech, you can produce high-quality videos without any video editing software.

✨ Features

• Markdown-Based: Write your slide content and narration script in a single text file.
• CLI, GUI, and API: Build from the command line, the Tkinter GUI (slidemovie -g), or Python code via the Movie API.
• Cross-platform: Supports Windows, macOS, and Linux.
• AI Narration: Automatically generates natural voiceovers using Google Gemini, OpenAI, Azure, or VOICEVOX (via multiai-tts).
• PowerPoint Integration: Use PowerPoint's AI "Designer" to create professional visuals instantly.
• No Video Editing: Audio and visuals are automatically synchronized.
• Incremental Builds: Only regenerates changed slides to save time and API costs.
• Long Narration Support: Optionally splits long narration into chunks for stable synthesis (--chunk-size).

🚀 Quick Start

1. Install

pip install slidemovie

Note: You also need to install FFmpeg, Pandoc, LibreOffice, and Poppler, and set up your AI API Key (Google or OpenAI). See the documentation for details.

To use the Tkinter interface instead of the command line, run:

slidemovie -g

Any options supplied with -g are used as the GUI's initial values, for example slidemovie demo -g --video.

The GUI summarizes status.json, including audio-file generation status. When its recorded TTS settings differ from the current settings, choose whether to use the recorded settings, overwrite them with the current settings, or cancel the build.

2. Create a Project

Create a Markdown file (e.g., demo.md):

# Slide Title

- Bullet point 1
- Bullet point 2

::: notes
This text will be read aloud by the AI narrator.
:::

3. Generate Slides

Convert Markdown to a draft PowerPoint file:

slidemovie demo -p

Open demo.pptx in PowerPoint, apply a design, and save it.

4. Build Video

Generate the final video with AI narration:

slidemovie demo -v

The output will be saved in movie/demo/demo.mp4.
