[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

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

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
