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.

What's New in v1.5.0

- Video Overlay: New operation to overlay a video on top of another video as a layer
- Flexible Positioning: Choose between alignment presets (left/center/right, top/middle/bottom) or custom coordinates
- Percentage-based Sizing: Scale overlay as percentage of main video dimensions
- Pixel-based Sizing: Specify exact pixel dimensions with aspect ratio preservation
- Opacity Control: Adjust overlay transparency (0-1)
- Time Control: Display overlay for specific time ranges
- Audio Handling: Choose main audio, overlay audio, mix both, or no audio
- FFmpeg Expressions: Support for advanced positioning using FFmpeg expressions

$3

- Bug Fix: Fixed "did not produce an output" error in Separate Audio operation when video source is not properly configured
- Added proper validation with clear error message when source is missing

$3

- Separate Audio: New Video operation to split video into muted video and extracted audio track
- Returns both outputs in a single item with customizable field names
- Support for multiple video formats (MP4, MOV, AVI, MKV) and audio formats (MP3, AAC, WAV, FLAC)
- Audio codec options including copy (no re-encoding) for fastest processing

$3

- Custom Output Field Names: Configure binary output field names for better workflow organization
- Enhanced Merge Node Support: Seamlessly work with n8n's Merge node for multi-input operations
- Automatic Resolution Handling: Smart scaling for videos with different resolutions in transitions
- Improved Error Messages: Better debugging with detailed binary property information

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.

Node: MediaFX

This is the main node for all media processing operations. You select a resource type and then an operation to perform on that resource.

Usage Examples

$3

When using n8n's Merge node to combine multiple video inputs:

1. Connect multiple video sources to a Merge node
2. Set Merge node to "Combine All" mode
3. In MediaFX node, set Binary Property names as data1, data2, etc. (matching Merge node output)
4. MediaFX will automatically detect and process all merged inputs

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.

$3

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:
`bash
sudo apt update && sudo apt install ffmpeg
`

CentOS/RHEL/Rocky Linux:
`bash
sudo yum install epel-release && sudo yum install ffmpeg


or for newer versions:


sudo dnf install ffmpeg
`

Alpine Linux (Docker):
`bash
apk add ffmpeg
`

macOS:
`bash
brew install ffmpeg
`
