Dub YouTube videos with AI
Use DubbyJam when you have a YouTube video or exported speech track and want a second-language dub for publishing or editing.
Typical workflow
- Download the video or its audio from a source you are allowed to use (DubbyJam does not fetch YouTube URLs)
- Keep audio under 20 MB; MP4/MOV video has a 1024 MB hard cap and account storage limit
- Upload to DubbyJam, set source/target language, and map speakers to voices
- Generate the dub, refine any individual cues in the result view, then download the dubbed video and audio tracks
- Video exports preserve the original picture and replace its audio; use the audio files for further editing when needed
Good fits
Explainers, vlogs, and commentary where the value is the spoken track. Multi-speaker skits work when ASR can separate roles; remap voices after analyze.
Limits to know
No automatic pull from youtube.com. Music-heavy beds and heavy overlap can hurt transcription. See Limits for formats and languages (English, Chinese, Spanish, French, Japanese).
