# HeyGen Avatar4 (Image to Video)

**Node type:** `video:heygen_avatar4_image_to_video`  
**Category:** `video`

## Description

HeyGen Avatar4 — turn a portrait image into a talking avatar video with audio or prompt+voice

## Pricing

- **Cost:** ~16 credits per seconds
- **Per-second rate:** The figure is the rate at a 5-second reference run. Our margin is progressive and steepest on the smallest runs, so a clip shorter than that can cost more per second, and a model priced with a flat multiplier is exact at every length. The charge is always computed from the real duration.
