n8n-nodes-mediafx

This repository contains a custom n8n node for comprehensive, local media processing using the power of FFmpeg. It allows you to perform a wide range of video, audio, image, and text operations directly within your n8n workflows without needing any external API or service.

Why use MediaFX?

• Privacy-Focused: All processing happens locally on your n8n instance. Your media files never leave your server.
• No External APIs: No need for API keys, subscriptions, or paying for a third-party service.
• Powerful: Leverages the full capabilities of FFmpeg for high-quality media manipulation.
• Self-Contained: FFmpeg is automatically downloaded and included via @ffmpeg-installer/ffmpeg. No manual installation of system dependencies is required in most cases.
• Flexible: Handles a wide variety of operations, from simple trims to complex audio mixing and text overlays.

Features

• Video Processing: Merge multiple clips, trim sections, apply transition effects between videos with automatic FFmpeg compatibility detection, and add fade-in/out effects to single videos.
• Advanced Audio Manipulation:
  • Extract audio from video in multiple formats (MP3, WAV, AAC, FLAC)
  • Mix audio tracks with precise volume control for each source
  • Partial Audio Mixing: Insert audio at specific time ranges with start time and duration control
  • Audio Looping: Automatically loop shorter audio to match desired duration
  • Independent Fade Effects: Apply fade-in and fade-out effects with customizable duration for both full and partial mixing
• Advanced Image Operations:
  • Convert images into video clips with custom dimensions and duration
  • Smart Watermarks: Control position, size, rotation, and opacity
  • Time Control: Display watermarks for specific time ranges or entire video
• Enhanced Text and Subtitles:
  • Burn text overlays with extensive styling (font, size, color, outline, background box)
  • Smart Positioning: Use alignment presets (left/center/right, top/middle/bottom) or custom coordinates
  • Padding Controls: Separate horizontal and vertical padding from edges
  • Add and style external subtitle files (.srt) with the same text styling options
• Font Management: Upload, list, preview, validate, and delete your own custom fonts (TTF, OTF) to be used in text operations.

Installation for n8n

1. Go to Settings > Community Nodes.
2. Click Install.
3. Enter n8n-nodes-mediafx in the Enter npm package name field.
4. Click Install again.

The node will be installed, and n8n will restart. You should then see the "MediaFX" node in your node panel.

For older n8n versions or manual installation:

1. Navigate to your n8n user data folder (by default, ~/.n8n/).
2. Enter the nodes directory: cd ~/.n8n/nodes.
3. Install the package: npm install n8n-nodes-mediafx.
4. Restart your n8n instance.

Requirements

• n8n: Version 1.0 or higher recommended.
• Node.js: Version 16+.
• FFmpeg: Automatically downloaded and included via @ffmpeg-installer/ffmpeg, with ffmpeg-static as fallback. Manual installation may be required on some systems.

FFmpeg Installation

The node automatically downloads FFmpeg via the @ffmpeg-installer/ffmpeg package (with ffmpeg-static as fallback), but if you encounter FFmpeg-related errors on your server, you may need to install FFmpeg manually:

Ubuntu/Debian:

sudo apt update && sudo apt install ffmpeg

CentOS/RHEL/Rocky Linux:

sudo yum install epel-release && sudo yum install ffmpeg
# or for newer versions:
sudo dnf install ffmpeg

Alpine Linux (Docker):

apk add ffmpeg

macOS:

brew install ffmpeg
