video translator faq
how does the video translator work?
upload your source video, choose a supported target language, and generate the translated audio. review it, then generate lip sync to match the new speech. if you already have translated audio, you can upload that track in the lip sync workflow.
can I translate youtube videos?
yes. use the source file for a video you own or have permission to translate. upload the lip-synced result as a separate youtube video. adding only an audio track to an existing youtube upload keeps its original picture and cannot carry new lip movements.
which languages can I translate into?
the dubbing workflow lists its supported target languages and regional variants. lip sync also accepts translated audio you provide, so you can use a separately recorded or generated track when a target language is unavailable in built-in dubbing.
is the lipsync realistic?
sync. labs generates mouth movements to match the translated speech. results depend on your footage and audio, so test a representative clip and review faces, pronunciation, and timing before publishing.
how long does it take to translate a video?
processing time depends on the video length and model. translation and lip sync are separate stages in the browser workflow. follow the progress shown for each job and allow time to review the result.
