Description

An open source automated video creation tool for generating short-form video content. Short Video Maker combines text-to-speech, automatic captions, background videos, and music to create engaging short videos from simple text inputs.

This project is meant to provide a free alternative to heavy GPU-power hungry video generation (and a free alternative to expensive, third-party API calls). It doesn't generate a video from scratch based on an image or an image prompt.

The server exposes an MCP and a REST server.

While the MCP server can be used with an AI Agent (like n8n) the REST endpoints provide more flexibility for video generation.

Features

• Generate complete short videos from text prompts
• Text-to-speech conversion
• Automatic caption generation and styling
• Background video search and selection via Pexels
• Background music with genre/mood selection
• Serve as both REST API and Model Context Protocol (MCP) server

How It Works

Shorts Creator takes simple text inputs and search terms, then:

1. Converts text to speech using Kokoro TTS
2. Generates accurate captions via Whisper
3. Finds relevant background videos from Pexels
4. Composes all elements with Remotion
5. Renders a professional-looking short video with perfectly timed captions

Limitations

• The project only capable generating videos with English voiceover (kokoro-js doesn’t support other languages at the moment)
• The background videos are sourced from Pexels

General Requirements

• internet
• free pexels api key
• ≥ 3 gb free RAM, my recommendation is 4gb RAM
• ≥ 2 vCPU
• ≥ 5gb disc space

Scene

Each video is assembled from multiple scenes. These scenes consists of

1. Text: Narration, the text the TTS will read and create captions from.
2. Search terms: The keywords the server should use to find videos from Pexels API. If none can be found, joker terms are being used (nature, globe, space, ocean)

Docker Command

docker run -it --rm --name short-video-maker -p 3123:3123 -e LOG_LEVEL=debug -e PEXELS_API_KEY= bilalnaseer/free-video-maker:latest
