AI Influencer Avatar Overlays

Make UGC-style videos that feel more “creator-on-camera” by overlaying a lip-synced circle avatar on top of your other scenes. Designed for Shorts and TikTok formats.

How it works

The AI Influencer content type has three modes:

Talking-head scenes — full-screen lip-synced presenter scenes (the classic behavior).
Avatar overlay only — no full-screen presenter scenes. A small circle avatar is overlaid on your other scenes.
Scenes + overlay — full-screen presenter scenes, plus the circle overlay on the other scenes.

For the circle overlay, VidMachine:

Generates a short presenter clip from your project Reference Image with LTX 2.5 Fast at 480p, then caches it on the project and reuses it for every video.
Lip-syncs the presenter clip to the narrator audio with MuseTalk — each continuous stretch between talking-head scenes, or the whole video in Avatar overlay only mode, split into chunks under MuseTalk’s 120-second audio limit.
Overlays the result as a circle in the final video, only where non-presenter scenes play (Scenes + overlay mode). Pick the corner and an optional colored ring border in project settings — bottom-right and no border by default.

Requirements

AI Influencer content type selected
Avatar overlays belong to the AI Influencer type and its mode.
Narrator must be enabled
Overlays are lip-synced to the narrator audio.
Reference image required
The presenter clip is generated from your project Reference Image the first time an overlay is needed, then cached and reused.
Another content type required
Overlay and Scenes + overlay modes need at least one other visual type (AI Video, AI Images, Stock Videos, Web Pages, or Web Images) for the avatar to sit on.
Overlay position
Choose the corner — top-left, top-right, bottom-left, or bottom-right (default). Applied at export time.
Overlay border (optional)
Add a colored ring around the circle overlay with the color picker, or leave it off for no border. Applied at export time.

AI Influencer mode
Talking-head scenes, Avatar overlay only, or Scenes + overlay.
Avatar overlay corner
Which corner of the video the circle avatar is burned into (overlay modes only).
Avatar overlay border
Optional color ring around the circle avatar (overlay modes only). Off by default.
Reference Image
Required. Defines the presenter identity for scenes and the overlay.
Use narrator voice
Must be enabled for avatar lip-sync to work.

Where to configure it

Open Projects, then Configure your project. Select AI Influencer in Basics and pick the AI Influencer mode in the Video generation section. When overlay mode is active, the Avatar overlay corner and Avatar overlay border settings appear right below the mode. The border is off by default — pick a color to add a ring. See How to create videos for the full project settings reference.

Credits for avatar overlays

Avatar overlay credits are calculated from the overlay-visible seconds of video. VidMachine bills at 1 credit per second, rounded up. Talking-head scenes are billed separately by their selected video model.

Quick start

Select AI Influencer and a mode

Choose Avatar overlay only or Scenes + overlay in project settings.

Add a reference image

Upload a clear portrait of your presenter. It defines the avatar for both scenes and the overlay.

Enable narrator voice

The avatar is lip-synced to the narrator audio; its presenter clip is generated from your reference image.

Generate your video

VidMachine generates a presenter clip from the reference image (reused for later videos), lip-syncs it to the narration, and burns the circle overlay into the final export.
