pyVideoTrans
What it is
pyVideoTrans is free, open-source software for translating videos that contain clear human speech. It automates speech recognition, subtitle translation, AI dubbing, and video assembly to create translated audio and subtitles. Other tasks include batch transcription into timed SRT files, subtitle dubbing, and batch SRT translation while preserving timestamps and formatting. The project lists more than 30 channels, including Faster-Whisper, F5-TTS, Qwen3-ASR, and Edge-TTS, with local offline and online API options. Interfaces include a desktop GUI, WebUI, and command line, with support for remote access, server deployment, and Docker use. Documented translation services include DeepL, Google Translate, Microsoft Translate, DeepSeek, ChatGPT, Gemini, and LibreTranslate. Speech options include OpenAI, ElevenLabs, Deepgram, Edge-TTS, Azure TTS, and local models. The maker describes the software as GPL-V3, with no feature limits or login requirement. Third-party API charges are separate, and users provide their own accounts and keys. It can run with or without an NVIDIA GPU, but cannot process media without clear human speech or remove hardcoded subtitles.
