Media Processing Skill
Process video, audio, and images using FFmpeg, ImageMagick, and RMBG CLI tools.
IMPORTANT: Invoke "/ck:project-organization" skill to organize the outputs.
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
