Process multimedia files with FFmpeg (video/audio encoding, conversion, streaming, filtering, hardware acceleration) and ImageMagick (image manipulation, format conversion, batch processing, effects, composition). Use when converting media formats, encoding videos with specific codecs (H.264, H.265, VP9), resizing/cropping 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.
Processes video, audio, and images using FFmpeg and ImageMagick for format conversion, encoding, optimization, and batch manipulation.

Use when:
Use FFmpeg for:
Use ImageMagick for:
| Task | Tool | Why |
|---|---|---|
| Video encoding | FFmpeg | Native video codec support |
| Audio extraction | FFmpeg | Direct stream manipulation |
| Image resize | ImageMagick | Optimized for still images |
| Batch images | ImageMagick | mogrify for in-place edits |
| Video thumbnails | FFmpeg | Frame extraction built-in |
| GIF creation | FFmpeg or ImageMagick | FFmpeg for video source, ImageMagick for images |
| Streaming | FFmpeg | Live streaming protocols |
| Image effects | ImageMagick | Rich filter library |
