YouTube Lip-Sync Feature: How Will It Work
YouTube Product Lead, Autodubbing, Buddhika Kottahachchi, told Digital Trends that the lip sync feature will modify the pixels on the screen to match the translated speech in a dubbed video. For this, YouTube needs to develop a 3D understanding of the world, lip shapes, teeth, face, and postures. He further explained that the tech is so far suited for full-HD videos, that is, 1080p. However, the 4K videos still need to wait.
The lip-sync feature will support several languages, such as English, Spanish, German, Portuguese, and French.
When Can We Expect It?
While there is no official word on it. The report suggested that the lip-sync feature is not broadly available, and there are no plans to make it available. Kottahachchi said that the lip-sync feature will be available to more creators, which will help YouTube understand the quality and constraints. It must be noted that the feature is still in the testing phase.
