Question 3

What types of audio can I lip sync to a video?

Accepted Answer

You can lip sync any audio including recorded speech, AI-generated voiceovers, music tracks, and dubbed dialogue in different languages. The AI supports common audio formats like MP3, WAV, and M4A. For best results, use clear speech audio without heavy background noise.

Question 4

Does lip sync work with any face in the video?

Accepted Answer

Yes, the AI can detect and sync lip movements for faces in your uploaded video. It works best with front-facing shots where the face and mouth are clearly visible. Both real people and AI-generated characters can be lip synced effectively.

Question 5

Can I use lip sync for dubbing videos into other languages?

Accepted Answer

Yes, AI lip sync is excellent for dubbing content into other languages. Record or generate a voiceover in the target language, then use lip sync to match the new audio to the original video. This creates a natural-looking result that is far more engaging than traditional subtitles.
