Video Body Swap on WaveSpeedAI: Put Your Face on Any Body in Any Video

What if you could star in a dance video without knowing the choreography? Appear in a fitness ad without hitting the gym? Show up in a movie scene without leaving your desk? Video Body Swap on WaveSpeedAI makes it possible — upload a face photo and a body video, and the AI composites your face onto the moving subject frame-by-frame with natural blending, consistent lighting, and identity preservation throughout the entire clip.

The result looks seamless: your face moves naturally with the body, lighting matches across every frame, and skin tones blend convincingly. No motion tracking, no rotoscoping, no VFX expertise required.

How Video Body Swap Works

The model takes two inputs: a face image (your portrait) and a target body video (the subject whose body you want to use). It then:

  1. Detects and tracks the subject’s face across every frame of the video
  2. Maps your facial features onto the tracked position, matching angle and perspective
  3. Blends lighting and skin tones for natural-looking compositing
  4. Maintains identity consistency so your face looks the same from frame 1 to frame last

The result is a video where the body performs its original actions — dancing, talking, walking, exercising — but with your face seamlessly integrated.

Key Features of Video Body Swap

  • Frame-by-Frame Consistency: Your face identity stays consistent across every frame, even during rapid movement, head turns, and lighting changes.

  • Natural Blending: AI matches skin tones, lighting direction, and shadow depth between the face and body for results that don’t look pasted on.

  • Two-Input Simplicity: Just a face photo and a body video — no masks, no keyframes, no manual editing of any kind.

  • Long Video Support: Process videos up to 120 seconds (2 minutes) per run.

  • REST API: Integrate video body swap into apps, content pipelines, or creative tools with a simple API call.
