[AI & Tools] 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.

[IMPORTANT] Use
TaskCreate
to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ask user whether to skip.

Quick Summary

Goal: Process multimedia files using FFmpeg for video/audio encoding, conversion, streaming, and filtering.

Workflow:

Identify -- Match input to correct FFmpeg operation (convert, trim, merge, compress)
Execute -- Run FFmpeg command with appropriate codec and quality settings
Verify -- Check output file integrity and quality

Key Rules:

Use tool selection table to pick correct FFmpeg operation
Prefer hardware-accelerated encoding when available
Always verify output file exists and is playable

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

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

bash

# 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

bash

# 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

IMPORTANT Task Planning Notes (MUST FOLLOW)

Always plan and break work into many small todo tasks
Always add a final review todo task to verify work quality and identify fixes/enhancements
