> Enhanced fork of n8n-nodes-mediafx with additional features and bug fixes.

This is a custom n8n node for comprehensive, local media processing using 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 This Fork

v1.6.35

Bug Fixes

• 🔊 Mix Audio (Audio-Speed mode): Fixed infinite execution caused by tpad generating endless video stream
• 📦 Package size reduced from ~12MB to ~6MB by removing duplicate font files

v1.6.34

Bug Fixes

• 🔊 Mix Audio (Audio-Speed mode): Fixed last portion of audio being silenced

– Changed amix duration to shortest so output ends when secondary audio ends

v1.6.33

Bug Fixes

• 🔊 Mix Audio (Audio-Speed mode): Fixed audio being cut off ~1 second before the end

– Added tpad to prevent video stream from ending before audio
– Added apad/atrim to stabilize video audio stream length

v1.6.30

Improvements

v1.6.28

New Features

– Works with older FFmpeg versions (no text_align dependency)
– Each line rendered as separate drawtext filter
– Line spacing option supported

v1.6.27

Improvements

– More reliable cross-platform support
– Fixes issues with old system FFmpeg being used instead of bundled version

v1.6.26

New Features

• 📐 Auto Font Size: Automatically calculate font size based on image dimensions

– Auto - Small: Fits text at 50% of calculated size
– Auto - Medium: Fits text at 75% of calculated size
– Auto - Large: Fits text at 100% (fills available width)

– Format info: filename, format, duration, size, bitrate
– Video stream: codec, resolution, frame rate, aspect ratio, pixel format
– Audio stream: codec, sample rate, channels, channel layout
– Tags: title, artist, album, and other embedded metadata

• 🔤 System Font Support: Use fonts installed on your system

– System fonts automatically appear in Font dropdown (Text/Subtitle operations)
– Supports macOS, Linux, and Windows system font directories
– Use Font > List with “Include System Fonts” to browse all available fonts

v1.6.14

Subtitle Enhancements (v1.6.1 ~ v1.6.14)

• 🎨 Background Box Padding: Fixed text sticking to background box edges

– Added horizontal padding (h hard spaces) when background is enabled
– Padding automatically scales with font size

• 🎯 Full ASS Format Support: Complete subtitle styling overhaul

– SRT to ASS auto-conversion for advanced styling

v1.6.0

• 🎬 Speed Operation: Adjust video playback speed (slow motion or fast forward)

– Speed range: 0.25x to 4x
– Option to adjust audio speed along with video
– Option to maintain original audio pitch
– Output format selection (MP4, MOV, AVI, MKV)

• 🐛 Subtitle Bug Fix: Fixed subtitle display issue with slideshow/image-sequence videos

– Changed from drawtext filter chain to subtitles filter
– The original drawtext filter’s enable='between(t,X,Y)' was unreliable with image-sequence videos
– Now uses FFmpeg’s native SRT parsing for correct timing

Why use this fork?

• Speed Control: Easily create slow-motion or fast-forward videos
• Reliable Subtitles: Fixed critical bug where subtitles were dropped on slideshow videos
• All original features from n8n-nodes-mediafx included

Usage Examples

Add Text to Image (New!)

Overlay text on an image with styling:

{
  "resource": "image",
  "operation": "addTextToImage",
  "sourceImageText": {
    "source": { "sourceType": "binary", "binaryProperty": "data" }
  },
  "imageText": "Hello, World!",
  "imageTextFontKey": "noto-sans-kr",
  "imageTextSize": 48,
  "imageTextColor": "white",
  "imageTextOutlineWidth": 2,
  "imageTextOutlineColor": "black",
  "imageTextPositionType": "alignment",
  "imageTextHorizontalAlign": "center",
  "imageTextVerticalAlign": "bottom",
  "imageTextPaddingY": 50
}

With background box:

{
  "resource": "image",
  "operation": "addTextToImage",
  "imageText": "Caption Text",
  "imageTextEnableBackground": true,
  "imageTextBackgroundColor": "black",
  "imageTextBackgroundOpacity": 0.7,
  "imageTextBoxPadding": 10
}

Get Media Metadata

Extract metadata from video or audio files:

{
  "resource": "probe",
  "operation": "getMetadata",
  "probeSource": {
    "source": { "sourceType": "binary", "binaryProperty": "data" }
  }
}

Example output:

{
  "success": true,
  "operation": "getMetadata",
  "format": {
    "filename": "video.mp4",
    "formatName": "mov,mp4,m4a,3gp,3g2,mj2",

    "size": 15728640,
    "bitRate": 1048576
  },
  "video": {
    "codec": "h264",
    "width": 1920,
    "height": 1080,
    "frameRate": 30,
    "aspectRatio": "16:9"

    "codec": "aac",
    "sampleRate": 48000,
    "channels": 2,
    "channelLayout": "stereo"
