Overview
What is LatentSync?
LatentSync is a lip-sync model created by ByteDance, based on audio-conditioned latent diffusion. It produces natural, smooth mouth movements on real videos and anime characters alike, with good temporal stability.
In Havincy, LatentSync re-syncs an existing video to a new audio track. Its flat pricing makes it an excellent option for longer videos.
