The traditional approach to creating talking-head videos requires cameras, lighting, microphones, and multiple takes. For developers and content creators who need spokesperson-style content at scale, this process is slow and expensive.
What if you could skip the entire filming process and generate a realistic talking video from just one photo and an audio clip?
What Is an AI Avatar Video?
An AI avatar video is a digitally generated clip where a static portrait photo is animated to speak in sync with an audio track. The AI analyzes the audio waveform, maps it to realistic lip movements, facial expressions, and subtle head motions — producing a video that looks like the person in the photo is actually talking.
Unlike deepfake technology used for deception, AI avatars are designed for legitimate content creation: marketing videos, educational content, product demos, and social media posts.
How to Create a Talking Avatar in 3 Steps
Getting started with Reelive's AI Avatar tool takes less than a minute:
1. Upload a portrait photo
Use a clear, front-facing headshot. Supported formats include JPG, PNG, and WebP (up to 10MB).
2. Upload your audio file
Record or upload an audio clip between 3 and 15 seconds. Supported formats: MP3, WAV, AAC, MP4, and OGG (up to 10MB).
3. Generate and download
Click the generate button. The AI processes your inputs and delivers a lip-synced MP4 video. You'll see a real-time progress indicator, and can preview your video as soon as it's ready.
That's it — no filming, no editing software, no retakes.
Key Features
Realistic Lip Sync
Powered by Kling AI Avatar Pro, the tool produces highly accurate lip synchronization. Mouth movements match the audio naturally, with realistic facial micro-expressions that avoid the uncanny valley effect.
Transparent Per-Second Pricing
You only pay for what you generate. Credits are calculated at 20 credits per second of video, based on your audio duration. A 5-second clip costs 100 credits, a 10-second clip costs 200 — simple and predictable.
Multiple Format Support
- Images: JPG, PNG, WebP (up to 10MB)
- Audio: MP3, WAV, AAC, MP4, OGG (up to 10MB, 3-15 seconds)
- Output: MP4 video with full lip synchronization
