AI Lipsync Generator

Upload a face video and an audio file (or text via TTS first) and get back a video where the mouth tracks the audio. The standard pipeline for AI avatars, dubbed content, multilingual product videos, and reactive character animations.

  • Models: Sync, Latentsync, Creatify, Veed Lipsync
  • Inputs: video URL + audio URL (or pair with TTS endpoints for text-driven flows)
  • Quality vs. cost spectrum — Sync is highest fidelity, Latentsync is fastest
