AI Auto Cutter — Remove Silence from Videos Instantly

Vido.LK's AI-powered silence remover automatically detects and removes silent or low-audio segments from your videos. Perfect for Sri Lankan content creators who want to trim dead air, pauses, and quiet sections from tutorials, vlogs, podcasts, and social media clips without manual editing.

How It Works

  1. Upload your video — supports MP4, MOV, WebM up to 500MB (Pro users)
  2. Choose a preset — Gentle, Normal, or Aggressive silence detection thresholds
  3. AI analyzes audio — our Python-based engine scans every frame using advanced silence detection algorithms
  4. Review detected cuts — interactive waveform shows exactly which segments will be removed
  5. Preview & export — watch the trimmed result before downloading, or adjust cuts manually
