Sebastjan Artič e06c3efb8e Add audio amplitude defense (Layer 3) for first-word cut prevention 
Žena problem persists: even after word-level extension, some cases where
Scribe doesn't transcribe the very first word still result in clip cutting
the vocal start.

Layer 3 defense: after word-level start extension, probe the FIRST 150ms
of audio at clip start with ffmpeg volumedetect. If mean_volume > -35 dB
(threshold for vocal/music vs silence), extend clip start back 0.5s as a
safety buffer.

This catches cases where:
- Scribe missed the word entirely (no word-level timestamp to extend to)
- LLM picked a start that's already inside vocal energy
- Word-level extension didn't trigger because no nearby word matched

The check is fast (<100ms) and conservative (only triggers if audio is
clearly NOT silent). If it's a true musical break (silence before chorus),
mean_volume will be < -40 dB and extension is skipped.

Three layers of defense now:
1. Claude prompt: 'start ~0.3s before first chorus word'
2. Word-level boundary detection (Scribe word timestamps)
3. Audio amplitude check (catches cases 1-2 missed)

Reels Clipper · biba.live

Self-hosted Opus Clip alternativa za FOLX TV / PTC. Pretvori 16:9 video v 9:16 reels/shorts/tiktok format z auto face tracking, podnapisi (sl/de/en) in avto-detekcijo refrena v glasbenih pesmih.

Features

  • 📤 Drag & drop upload (do 2 GB)
  • 📺 YouTube URL paste (yt-dlp)
  • 🎯 Smart reframe: track (face follow), center, blur (za glasbo)
  • 🎵 Auto-chorus detection (Whisper + energy hibrid)
  • 📝 Burned-in podnapisi (faster-whisper, multi-jezik)
  • 🎨 3 stili podnapisov: reels, yellow (MrBeast), minimal
  • 🔐 HTTP Basic Auth
  • 📊 Real-time progress (Server-Sent Events)
  • 📦 Docker / Coolify ready

Quick start (lokalno)

docker compose up --build
# odpri http://localhost:8000

Default login: sebastjan / nastavi AUTH_PASS v .env.

Coolify deploy

  1. V Coolify ustvari nov projekt → Docker Compose iz tega repoja
  2. Domena: reels.biba.live
  3. Env vars: 
    AUTH_USER=sebastjan
AUTH_PASS=<močno geslo>
MAX_UPLOAD_MB=2000
  4. Volume reels_data se ustvari avtomatsko
  5. Deploy → Coolify postavi Traefik reverse proxy + SSL via Let's Encrypt
