Individual skill
stitch-videos-ffmpeg
Stitch video segments with ffmpeg concat, xfade, overlay, audio mux, and export settings, and trim a source into named clips at exact windows (trim_clips.py). Ships montage.py, a free montage assembler (python3 + ffmpeg, no keys). It takes a JSON EDL of clips and stills, normalizes them and hard-cuts them in order, burns captions from an SRT, a cue list or word timings, and lays a VO over a music bed that ducks under it, mastered to -14 LUFS.

# stitch-videos-ffmpeg
## Purpose
Stitch video segments with ffmpeg concat, xfade, overlay, audio mux, and export settings.
Implementation status: refactored from existing repository skills. The workflow consolidates behavior that previously lived across larger skills.
Sources: ad-studio, voiceover-product-ad, ugc-product-video, voiceless-music-transformation-reel, product-stopmotion-ad.
Extraction notes: assembly and composite scripts.
## Montage helper: `scripts/montage.py`
