Talking Avatar Overlays

Make UGC-style videos that feel more “creator-on-camera” by overlaying a lip-synced talking avatar on top of your AI-generated video. This is designed for Shorts and TikTok formats, where a short, narrated hook can make your content perform.

How it works

When you enable narration and select a talking avatar, VidMachine generates a talking avatar video by lip-syncing the avatar to your narrator audio, then overlays that avatar into the final video (top-left corner).

Requirements

Narrator must be enabled
Talking avatar overlays only generate when `Use narrator voice` is turned on.
Avatar selection is optional
If you do not pick a `Talking Avatar (Optional)`, the project still generates normally (narrator only).
Overlay position
The talking avatar overlay is placed in the top-left corner.

Use narrator voice
Must be enabled for avatar lip-sync to work.
Talking Avatar (Optional)
Pick the avatar you want to overlay.

Where to configure it

Go to Projects in the dashboard, open your project settings, then set:

Credits for talking avatar overlays

Avatar overlay credits are calculated from your narrator audio duration. VidMachine bills at 8 credits per second of output time, rounded up to whole seconds.

Quick start

Enable narrator voice

Open your project and turn on `Use narrator voice`. Talking avatar overlays are generated from the narrator audio.

Select an optional talking avatar

In Project Settings, choose a `Talking Avatar (Optional)`. If you leave it blank, the narrator plays without an avatar overlay.

Generate your video

When you generate a video, VidMachine lip-syncs the talking avatar to your narrator audio and overlays it on top of the video.

Publish as UGC-style Shorts/TikTok

Schedule or publish the result to your connected YouTube Shorts and/or TikTok accounts.
