VideoTrans

VideoTrans translates and dubs talking videos into another language — entirely on your Mac, with no cloud processing and no account required. Import any video, and VideoTrans will: - Isolate the spoken voice from music and background sound - Transcribe the speech, word by word - Translate it into your target language - Synthesize natural-sounding speech in the new language, time-aligned to the original - Export a new video with dubbed audio (background and music preserved), plus subtitle files (SRT/VTT) in both languages Choose a generic preset voice for the target language Everything runs on-device using open, local speech and translation models — your video and audio never leave your device. An internet connection is only used for two optional features: downloading additional voice/model options on first use, and importing a video directly from a URL.
