pyVideoTrans

pyVideoTrans is an open-source video translation software that translates spoken audio into another language and embeds new dubbing and subtitles.

pyVideoTrans is an open-source software designed to translate videos from one language to another by recognizing spoken voice rather than relying on existing subtitles. Users can automate the entire process, which includes speech recognition, subtitle translation, AI dubbing, and video synthesis to generate a new video with target language subtitles and voiceover. It also provides batch speech transcription, subtitle dubbing, and SRT subtitle translation functions. The software integrates over 30 channels and AI models such as Faster-Whisper, F5-TTS, Qwen3-ASR, and Edge-TTS, supporting both local offline and online API combinations. It operates across desktop GUI, WebUI, and CLI command-line modes to suit local use, remote access, server deployment, and Docker containerization. It requires no login or registration and runs on Windows, macOS, and Linux.
