Lip sync
Mouth shaped to your audio, frame by frame
InfiniTalk reads the audio waveform and reshapes the mouth, jaw and lip line to match. Speech feels delivered, not pasted on.
Audio-driven talking head
InfiniTalk.
InfiniTalk turns a portrait and an audio clip into a lip-synced talking-head video. Per-second pricing visible before render - useful for explainers, creator drops and walkthroughs.

What InfiniTalk can do
Six things InfiniTalk does for talking-head workflows.
Portrait + audio
Two inputs, one talking head
A portrait image and a speech audio file are all that’s needed. No green screen, no body capture rig, no real shoot day.
Per-second pricing
Cost is shown by audio length
Longer audio costs more credits - the meter shows the per-second rate upfront so you can budget the explainer before you render.
Multi-language
Works in any spoken language
Lip sync follows phonemes rather than English-only words, so multilingual explainers and global localisations work cleanly.
Creator-friendly
Reuse a single brand portrait
Lock in one approved portrait and reuse it across every video - perfect for consistent creator drops or company spokesperson clips.
Pairs with ElevenLabs
Generate the script audio in the same studio
Use our ElevenLabs TTS or Text-to-Dialogue to generate the speech, then feed it straight into InfiniTalk. End-to-end script-to-video without leaving FCKexpensive.AI.
