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.

When the user wants to write, rewrite, or improve marketing copy for any page — including homepage, landing pages, pricing pages, feature pages, about pages, or product pages. Also use when the user says "write copy for," "improve this copy," "rewrite this page," "marketing copy," "headline help," "CTA copy," "value proposition," "tagline," "subheadline," "hero section copy," "above the fold," "this copy is weak," "make this more compelling," or "help me describe my product." Use this whenever someone is working on website text that needs to persuade or convert. For email copy, see email-sequence. For popup copy, see popup-cro. For editing existing copy, see copy-editing.

Media Processing Skill
Process video, audio, and images using FFmpeg and ImageMagick command-line tools for conversion, optimization, streaming, and manipulation tasks.
When to Use This Skill
Use when:
- Converting media formats (video, audio, images)
- Encoding video with codecs (H.264, H.265, VP9, AV1)
- Processing images (resize, crop, effects, watermarks)
- Extracting audio from video
- Creating streaming manifests (HLS/DASH)
- Generating thumbnails and previews
- Batch processing media files
- Optimizing file sizes and quality
- Applying filters and effects
- Creating composite images or videos
Tool Selection Guide
FFmpeg: Video/Audio Processing
Use FFmpeg for:
- Video encoding, conversion, transcoding
- Audio extraction, conversion, mixing
- Live streaming (RTMP, HLS, DASH)

ImageMagick: Image Processing
- Image format conversion (PNG, JPEG, WebP, GIF)
- Resizing, cropping, transformations
- Batch image processing (mogrify)
- Visual effects (blur, sharpen, sepia)
- Text overlays and watermarks
- Image composition and montages
- Color adjustments, filters
- Thumbnail generation

Performance Tips
- Use CRF for quality control - Better than bitrate for video
- Copy streams when possible - Avoid re-encoding with
-c copy
- Hardware acceleration - GPU encoding 5-10x faster
- Appropriate presets - Balance speed vs compression
- Batch with mogrify - In-place image processing
- Strip metadata - Reduce file size with
-strip
- Progressive JPEG - Better web loading with
-interlace Plane
- Limit memory - Prevent crashes on large batches
- Test on samples - Verify settings before batch
- Parallel processing - Use GNU Parallel for multiple files
