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
