Tero Subtitler is an open source, cross-platform, and free subtitle editing software.

What it solves

Tero Subtitler is a free, open-source, cross-platform subtitle editing software designed to handle the entire subtitling workflow, from transcription and translation to final quality control and video dubbing.

How it works

It integrates several powerful external tools and engines to provide a comprehensive suite of features:

  • Transcription: Uses whisper.cpp and Faster-Whisper for automatic audio-to-subtitle conversion.
  • Playback & Manipulation: Employs mpv for multimedia playback and FFmpeg for audio/video manipulation.
  • OCR: Uses Tesseract for optical character recognition.
  • Translation: Integrates the Google Translate API for automatic translation.
  • Dubbing: Uses ElevenLabs TTS for video dubbing.
  • Video Sourcing: Uses yt-dlp to import videos via URL.

Who it’s for

It is designed for subtitlers, translators, and video producers who need a professional-grade tool for creating, editing, and validating subtitles across various formats.

Highlights

  • Comprehensive Editing: Supports SMPTE and Media modes, multi-level undo/redo, and a timeline with a waveform visualizer.
  • Advanced Tools: Includes frame/video rate conversion, spell check, and industry-standard validation profiles.
  • AI-Powered Automation: Features automatic transcription and translation.
