Introducing Half Moon AI Video Face Swap on WaveSpeedAI

Realistic Video Face Swapping Is Here — Meet Half-Moon AI Video Face Swap on WaveSpeedAI

What if you could seamlessly place any face into any video — and have it look completely natural? Not a rough cut-and-paste job, but a frame-by-frame transformation where skin tones match, expressions track perfectly, and the result is so smooth you’d never know the face was swapped.

That’s exactly what Half-Moon AI Video Face Swap delivers, and it’s now available on WaveSpeedAI with instant inference, no cold starts, and pricing that starts at just fractions of a cent per second.

What Is Half-Moon AI Video Face Swap?

Half-Moon AI Video Face Swap is an AI-powered portrait-transfer model that takes a face from a single source image and realistically blends it onto a person in a target video. Unlike earlier face-swap tools that produced jarring, uncanny results, this model processes every frame individually while maintaining temporal consistency across the entire clip.

The result: swapped faces that move naturally, react to lighting changes, and follow the original subject’s expressions and head movements — all without flicker, jitter, or the telltale artifacts that plagued previous-generation tools.

Key Features

Frame-by-frame temporal consistency. The swapped face remains stable across every frame, even during rapid head movements, turns, and changes in expression. No flickering, no ghosting — just smooth, continuous video.
Dynamic skin-tone and lighting matching. The model doesn’t just paste a face onto the video. It analyzes the lighting, shadows, and color temperature of each frame and adapts the source face accordingly, creating a seamless blend that respects the scene’s visual context.
Expression and pose tracking. The swapped face mirrors the target subject’s full range of facial expressions — smiles, frowns, raised eyebrows, subtle lip movements — along with head rotations and tilts. The result looks natural and believable.
Dead-simple two-input workflow. No complex parameter tuning. No manual masking. Upload a source face image, upload a target video, and hit run. The model handles alignment, blending, and rendering automatically.
Cost-effective processing. At $0.024 per second of target video, a 10-second clip costs just $0.24 and a full minute runs $1.44. That’s production-quality face swapping at a price point accessible to individual creators, not just studios.

Real-World Use Cases

Video face swapping has become a staple of creative content. Place yourself into trending video formats, create reaction content with a twist, or produce entertaining clips for TikTok, Instagram Reels, and YouTube Shorts. The temporal consistency means your content looks polished, not gimmicky.

Marketing and Advertising

Brands can rapidly produce localized or personalized video campaigns. Swap in regional brand ambassadors, test different spokesperson options before committing to a full shoot, or create variations of an ad for A/B testing — all from a single base video.

Film and Video Pre-visualization

Before investing in expensive reshoots or extensive makeup, filmmakers and video producers can use face swapping to previsualize casting choices, test how different actors look in a scene, or mock up concepts for client approval.

Entertainment and Creative Projects

Put yourself into your favorite movie scenes. Create personalized birthday or holiday greeting videos. Build creative projects that blend reality and imagination. The high quality of the output means these aren’t just throwbacks to crude deepfake demos — they’re genuinely impressive creative tools.

Getting Started on WaveSpeedAI

Getting up and running takes minutes. Here’s how to use the model through WaveSpeedAI’s API:

import wavespeed

output = wavespeed.run(
    "half-moon-ai/video-face-swap",
    {
        "source_face": "https://your-source-face-image.jpg",
        "target_video": "https://your-target-video.mp4",
    },
)

print(output["outputs"][0])  # Output video URL

That’s it. Two inputs, one API call, and you get back a URL to your processed video.

For best results:

Use a clear, well-lit, front-facing photo as your source face. Avoid sunglasses, heavy shadows, or extreme angles.
Higher-resolution target videos produce sharper, more detailed face swaps.
For longer videos, consider trimming to key segments first — shorter clips process faster, and you can always run multiple segments.

WaveSpeedAI handles all the infrastructure. There are no cold starts, so your first request is just as fast as your hundredth. The model is always warm and ready to process, which matters when you’re building face-swap features into a product or iterating quickly on creative work.
