pyVideoTrans is an open-source video translation and dubbing tool that converts spoken audio and subtitles from one language to another. It recognizes human speech in videos and processes translation independently of existing subtitles. The software provides a fully automated pipeline including speech recognition, subtitle translation, AI dubbing, and video compositing. It supports 30+ AI models such as faster-whisper, f5-tts, qwen3-asr, and edge-tts for both local offline and online API use. Users can run the tool through a desktop GUI, web interface, or command-line interface. The software works on laptops and desktops with or without an NVIDIA GPU, offering CUDA acceleration when available. It is released under the GPL-v3 license with no feature restrictions, login requirements, or registration needed.
