Key Features — Infinite Talk AI

Whole-frame control

Audio drives lips, gaze, head turns, and posture together so motion stays in sync while identity stays stable.

Sparse-frame dubbing

Keyframes land on important beats; in‑between frames follow audio so performance feels smooth instead of robotic.

Temporal context windows

Overlapping windows carry motion across chunks, cutting seams and flicker on long videos.

Soft reference control

Reference strength adapts to the frame, keeping faces on‑model while head and body stay expressive.

Multi‑speaker pipelines

Drive several characters with separate audio tracks and masks in the same scene.

Clarity & style controls

Simple sliders and prompts adjust lip strength, expression range, and style without touching code.
