pyVideoTrans
A free, open-source tool that translates videos by chaining speech recognition, subtitle translation, AI dubbing and video compositing, with local models or online APIs.
About pyVideoTrans
Translating a video usually means moving between separate tools for transcription, subtitle translation, voice-over and re-rendering.
Who it’s for
- Creators who localize videos into other languages
- Users who want to mix local speech models with their own translation or TTS API keys
When to consider it
Consider pyVideoTrans when you want a free desktop, web or command-line pipeline that outputs a video with translated subtitles and dubbing.
Tradeoffs & limitations
- GPL-3.0 licensed and free with no login; paid APIs such as DeepSeek or Gemini are billed by those providers.
- A pre-built package is offered for Windows; macOS and Linux users install from source.
