Features

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.

Parameters

How to Use

1. Upload source_face_1 and select the matching source_gender_1.
2. (Optional) Upload source_face_2 and select source_gender_2 to swap a second face.
3. Upload the target video — a video containing one or two people.
4. Run — the model matches each source face by gender and processes the video frame by frame.
5. Download the output video.

Pricing

$0.03 per second of the target video.

Billing Rules

• Billed by the duration of the target video in seconds

Examples

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

• 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.
