Video Assembly
Combines outputs from video and voice pipelines into final deliverable videos.
Two Assembly Modes
Mode 1: FFmpeg (Simple, Fast)
Best for: Concatenation, audio mixing, basic transitions, format conversion.
No dependencies beyond FFmpeg (pre-installed on most systems).
Mode 2: Remotion (Complex Compositions)
Best for: Animated captions, data visualizations, complex motion graphics, React-based templates.
Uses existing remotion-best-practices skill for guidance.
FFmpeg Operations
Concatenate Video Clips
```bash
Create file list
echo "file 'clip1.mp4'" > filelist.txt echo "file 'clip2.mp4'" >> filelist.txt echo "file 'clip3.mp4'" >> filelist.txt
Concatenate (same codec/resolution)
ffmpeg -f concat -safe 0 -i filelist.txt -c copy output.mp4

FFmpeg Patterns provides ready-to-use command examples for video and audio tasks like transcoding to MP4 or WebM, extracting audio tracks, trimming clips, applying filters, merging media, generating thumbnails, and streaming formats. It covers hardware acceleration, batch operations, and practical probing commands.
This skill harnesses FFmpeg to handle video and audio editing tasks—trimming, transcoding, resizing, concatenating, adding subtitles, overlaying graphics, color grading, audio normalization, and green-screen compositing. It supports modern codecs (H.264, H.265, VP9, AV1) and GPU-accelerated encoding via NVIDIA NVENC, Intel QSV, and Apple VideoToolbox, with helper scripts for common workflows.

Video Processing & Editing automates FFmpeg-based workflows for cutting, trimming, concatenating, and exporting video content. It handles audio mixing, subtitle management, and platform-specific optimization without requiring manual editing interfaces. Use it for production pipelines and batch processing; not for real-time UI editing or 3D compositing.
Video Edit runs ffmpeg directly to handle common video tasks—trimming clips, joining multiple files, resizing for social platforms, adjusting playback speed, swapping audio tracks, and converting between formats. Built-in presets for TikTok, YouTube, Instagram, and other platforms streamline resizing with proper aspect ratio handling.
Clipify turns long-form videos into vertical social clips by identifying clip-worthy moments via transcription, automatically reframing 16:9 footage to 9:16 with motion-based face tracking, and applying word-level captions. It detects punchlines, reversals, and audio peaks to propose 3–5 candidates, then renders with hardware acceleration on macOS.
