In their own words
pyVideoTrans
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 produce translated audio and subtitles. It also supports batch transcription into timed SRT files, subtitle dubbing, and batch SRT translation while preserving timestamps and formatting. The project offers a desktop GUI, WebUI, and command-line interface, with documentation for remote access, server deployment, and Docker use. It lists more than 30 channels, including Faster-Whisper, F5-TTS, Qwen3-ASR, and Edge-TTS, with local offline and online API options. Source deployment instructions cover macOS, Linux, and Windows, and a Windows 10/11 package is provided. The software is described as having no feature limits or login requirement under GPL-V3. Third-party API use may incur separate charges, and users provide their own accounts and keys.
