Frequently Asked Questions
What type of videos work best for lipsyncing?
Videos with clear, front-facing human subjects and consistent speech ("talking head" video, interviews, vlogs, etc). For best results, avoid fast cuts, face obstructions, or extreme head movements.
Does Sieve's lipsyncing require training?
Unlike most other providers who require 2-3 minutes of "training" video, Sieve offers a training-free approach. Simply upload your video and target audio & Sieve will handle the rest.
How often does Sieve incorporate the newest underlying models?
We regularly incorporate the latest & best available models - keeping up with the SoTA so you don't have to.

You can also run Lipsync directly within our Dubbing function! Simply select "enable_lipsyncing".
