Overview

HeyGen Avatar 4 — Talking Avatar Videos from Text or Audio

HeyGen Avatar 4 turns any avatar image plus a script or voice recording into a talking AI avatar video — billed by duration at 1 token per 5 seconds of speech. On Prizmad it's built in: upload a face or pick a preset actor, add audio, generate.

Background

What is HeyGen Avatar 4?

HeyGen Avatar 4 is an image-to-talking-video model: give it one clear avatar image and something to say, and it renders a lip-synced presenter video. Unlike avatar tools locked to a fixed cast, Avatar 4 works with any face — choose a preset actor from the picker or upload your own image (JPG, PNG, WebP, or AVIF up to 10 MB) to turn a founder photo, a brand mascot shot, or an AI-generated character into a spokesperson.

Audio comes from either of two modes. Generate from Text sends your script with one of the built-in HeyGen voices and creates the speech for you. Upload Audio takes a clean voice recording of up to 60 seconds and lip-syncs the avatar to it precisely. Either way you control the output shape — six aspect ratio options including 9:16, 4:5, and 1:1, resolutions from 360p to 1080p — plus a Talking Style setting: Stable keeps motion subtle, Expressive adds more avatar movement.

On Prizmad, HeyGen Avatar 4 uses the same token balance as , video, voiceover, , and music. No HeyGen account, no API key — you pay in the same tokens as every other tool, your videos land in the same asset library, and everything you generate is yours to use commercially.
