VideoTrans vs DoubleVoix

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.

DoubleVoix turns a video into a bilingual, consecutively-interpreted program: the speaker is heard in their own words, then an interpreter voices each passage in your chosen language, before the original picks back up — the rhythm of a live interpreter at a service, conference or summit, not a dub laid on top. HOW IT WORKS 1. Paste a link or upload a video file. 2. Choose the source and target language. 3. Confirm you hold the rights to that video. 4. Get back your interpreted video, bilingual captions burned in, ready to share. No editing skill required. DoubleVoix automatically splits the speech into natural passages, translates each one, synthesizes an interpreter's voice, then reassembles the program: original audio, a freeze-frame on the speaker during interpretation, the source picking back up — on repeat to the end. WHO IT'S FOR Pastors and ministries translating a sermon, conference and summit organizers, creators reaching an audience that speaks more than one language, diaspora families and communities. PRICING A free trial is available with no account needed. Extra minute packs (one-time purchase, no subscription) are available in the app once you've signed up. The result is a machine translation: like any interpreter's work, it deserves a read-through before it's published.
