AI DubbingStudioAI lip sync adjusts one front-facing presenter’s mouth movements to translated speech. Use a video longer than 1 second and up to 210 seconds.
AI lip sync adjusts mouth movements after translated speech is generated. It is an optional part of video dubbing for a single front-facing speaker. Preview the voice first; mouth adjustment runs with the full dub.
Use MP4, MOV or WebM up to 200 MiB, longer than 1 second and up to 210 seconds. Choose a single, clearly visible, front-facing presenter. Group scenes, screen recordings and voice-over footage are better suited to dubbing without lip sync.
Lip sync adds a per-language charge to full dubbing. A lip-sync failure can still deliver the dub while releasing the separate lip-sync reservation. Editing a successfully synced sentence can redo its mouth-adjustment window and has a quote to confirm.
Review transcription, translation, pronunciation and mouth alignment before publishing. Upload only video, voices, music and images you own or have permission to use. This is recorded-file dubbing, not live interpretation. See pricing and the terms.
Detected speakers receive stock voices; voices can repeat when the catalogue is exhausted. Optional cloning is limited to a single identified speaker with consent and enough usable sample speech. Speaker renaming and reassignment are not offered.
Use a clearly visible, front-facing presenter. Lip sync is video-only and runs after voice generation, with its own quote. Side profiles, occlusion and fast movement can reduce quality; mouth alignment is not guaranteed.
After full dubbing, read the source transcript beside the translation and edit translated sentences with a quote for each regeneration. Download mixed audio, voice-only audio and separate source/translated SRT and VTT; video output requires video input.
