Media Processing

Process multimedia files with FFmpeg (video/audio encoding, conversion, streaming, filtering, hardware acceleration), ImageMagick (image manipulation, format conversion, batch processing, effects, composition), and RMBG (AI-powered background removal). Use when converting media formats, encoding videos with specific codecs (H.264, H.265, VP9), resizing/cropping images, removing backgrounds from images, extracting audio from video, applying filters and effects, optimizing file sizes, creating streaming manifests (HLS/DASH), generating thumbnails, batch processing images, creating composite images, or implementing media processing pipelines. Supports 100+ formats, hardware acceleration (NVENC, QSV), and complex filtergraphs.

Media Processing Skill

Process video, audio, and images using FFmpeg, ImageMagick, and RMBG CLI tools.

Tool Selection

Task	Tool	Reason
Video encoding/conversion	FFmpeg	Native codec support, streaming
Audio extraction/conversion	FFmpeg	Direct stream manipulation
Image resize/effects	ImageMagick	Optimized for still images
Background removal	RMBG	AI-powered, local processing
Batch images	ImageMagick	mogrify for in-place edits
Video thumbnails	FFmpeg	Frame extraction built-in
GIF creation	FFmpeg/ImageMagick	FFmpeg for video, ImageMagick for images

Installation

# macOS
brew install ffmpeg imagemagick
npm install -g rmbg-cli

# Ubuntu/Debian
sudo apt-get install ffmpeg imagemagick
npm install -g rmbg-cli

# Verify
ffmpeg -version && magick -version && rmbg --version

Essential Commands

# Video: Convert/re-encode
ffmpeg -i input.mkv -c copy output.mp4
ffmpeg -i input.avi -c:v libx264 -crf 22 -c:a aac output.mp4

# Video: Extract audio
ffmpeg -i video.mp4 -vn -c:a copy audio.m4a

# Image: Convert/resize
magick input.png output.jpg
magick input.jpg -resize 800x600 output.jpg

# Image: Batch resize
mogrify -resize 800x -quality 85 *.jpg

# Background removal
rmbg input.jpg                          # Basic (modnet)
rmbg input.jpg -m briaai -o output.png  # High quality
rmbg input.jpg -m u2netp -o output.png  # Fast

Key Parameters

FFmpeg:

-c:v libx264 - H.264 codec
-crf 22 - Quality (0-51, lower=better)
-preset slow - Speed/compression balance
-c:a aac - Audio codec

ImageMagick:

800x600 - Fit within (maintains aspect)
800x600^ - Fill (may crop)
-quality 85 - JPEG quality
-strip - Remove metadata

RMBG:

-m briaai - High quality model
-m u2netp - Fast model
-r 4096 - Max resolution
