AI Lip-Sync Could Be the Missing Link in Video Translation, Tests of SyncSo, Rask and HeyGen Show

The author argues current AI video translation (YouTube autodubbing, Instagram translation) has a persistent flaw: the audio is translated but the speaker's mouth movements betray the original language. Testing specialized lip-sync models — SyncSo, Rask, and HeyGen — some results were genuinely convincing, with clips viewers couldn't tell were AI-generated.
The bigger picture: much high-quality educational content is locked behind English, and making speakers appear native to viewers' language could matter more than dubbing itself. Obvious commercial applications include movies, online courses, advertising, training videos, and interviews.
