Repurpose Videos into Reels
Automatic reel extractor with smart framing, subtitles & speaker focus

From a long‑form YouTube video to tightly edited, portrait‑ready reels – fully automated.
Pipeline:
- URL ingestion → transcript + temporal semantic clustering (Llama 3.1).
- Local (browser / edge) download via ytdl-core + FFmpeg segment handling.
- WhisperX forced alignment refines speech boundaries → high precision candidate segments.
- Meta SAM v2 performs frame object segmentation & adaptive cropping so speaker stays centered in portrait.
- Subtitle enhancement layer adds pacing, emphasis punctuation & selective emojis.
- Final burn‑in & aspect conversion via FFmpeg.
Result: share‑ready vertical clips with minimal manual editing.
