AI Subtitle Translator
AI Subtitle Translator
Web-based AI subtitle translator for SRT, VTT, ASS, SSA, and SUB that preserves timing and improves natural localization.
Key features
- Multi-Format Support: Accepts and outputs common subtitle file formats including SRT, VTT, ASS, SSA, and SUB to maintain compatibility with various video tools and players.
- Timing & Cue Preservation: Keeps original timestamps and cue structure intact so translated files can be dropped back into videos without re-timing or manual alignment.
- AI-Powered Localization: Uses AI to produce translations that better match scene context and conversational tone, reducing literal or awkward phrasing.
- Minimal Manual Fixing: Produces output designed to require less post-editing by translators or editors through improved scene fit and contextual translations.
- Web-Based Workflow: Operates as an online tool allowing users to upload subtitle files and download translated versions without local installs or complex setups.
- Supports common subtitle formats: SRT, VTT, ASS, SSA, SUB (and LRC in some forks)
- LLM-based translation via OpenRouter/OpenAI/Gemini/Claude/Llama/Mistral and traditional APIs (DeepL, Google Translate, Azure) depending on implementation
- REST API endpoints (health, models, status, config, translate content/file, async job submission, job listing) in FastAPI-based implementations
- Synchronous and asynchronous job processing with background worker and job queue (SQLite persistence in some projects)
- Adaptive batch sizing, parallel batch processing, and retry logic for robust throughput
- Context-aware batching (send preceding/succeeding subtitle context to LLMs to improve coherence and scene fit)
- Translation caching to avoid repeated API calls and reduce cost
- Real-time progress reporting and cost tracking for async jobs
- CLI tools and pip-installable packages in some projects (pip install subtitle-ai-translator)
