Half-Moon AI Video Multi-Face Swap | Multiple Face Swap in Video

Video Face Swap Multi

Video Face Swap Multi is an AI-powered face-swapping model that can transfer up to two faces onto a target video simultaneously. It uses gender-based matching to accurately assign each source face to the correct person, delivering smooth, temporally consistent multi-face swaps across every frame.

Why Choose This?

Multi-face video swap in one pass Swap up to two faces in a single video at once — no need to run separate jobs per face.
Gender-based face matching Specify the gender for each source face so the model accurately maps faces to the right people throughout the video.
Frame-by-frame consistency The swapped faces stay stable across all frames with minimal flicker or jitter, even during motion and camera changes.
Natural blending Skin tone, lighting, and shadows are dynamically matched per face and per frame for realistic results.
Built-in safety checker Optional safety filter to screen outputs for inappropriate content.

Best Use Cases

Group Video Edits — Swap multiple faces in couple or group videos in one step.
Content Creation — Create fun multi-face-swap video content for social media and entertainment.
Marketing & Advertising — Produce personalized video content featuring different face combinations.
Pre-visualization — Test different face pairings in video projects before full production.

Pro Tips

Use clear, well-lit source faces with minimal occlusion for the best results.
Make sure the gender selection matches each source face — incorrect gender assignment may cause faces to swap onto the wrong person.
For single-face video swaps, just provide source_face_1 and leave source_face_2 empty. Or use Video Face Swap for a simpler workflow.
Shorter clips process faster and cost less — trim to key segments when possible.

Notes

If you provide a URL instead of uploading locally, make sure the URL is publicly accessible. A successfully accessible image or video will display a preview in the interface.
The Safety Checker is enabled by default. Disable it only if you are confident your inputs and outputs comply with platform policies.
Please use this model responsibly and in compliance with applicable laws and platform policies.
