# 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:

1. 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.
2. 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.
3. 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 which corner the circle overlay sits in: 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.

## 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](https://vidmachine.ai/docs/guides/create-videos.md) 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

1. **Select AI Influencer and a mode.** Choose **Avatar overlay only** or **Scenes + overlay**.
2. **Add a reference image.** Upload a clear portrait of your presenter in project settings.
3. **Enable narrator voice.** The avatar is lip-synced to the narrator audio.
4. **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.
5. **Publish as UGC-style Shorts/TikTok.** Schedule or publish the result to your connected YouTube Shorts, TikTok, or Instagram accounts.

You can also regenerate the overlay for a single video from the video page.
