Video Face Swap
Video Face Swap is an AI-powered face-swapping model that transfers a face from a source image onto every frame of a target video. It delivers smooth, temporally consistent results with natural facial alignment, skin-tone matching, and expression adaptation — producing seamless face swaps across entire video clips.
Why Choose This?
-
Frame-by-frame consistency The swapped face stays stable across all frames with minimal flicker or jitter, even during motion.
-
Natural blending Skin tone, lighting, and shadows are dynamically matched frame by frame to maintain a realistic look throughout the video.
-
Expression and pose tracking The model follows the target's facial movements, expressions, and head rotations for a natural, believable result.
-
Simple two-input workflow Just upload a source face and a target video — the model handles the rest automatically.

Pro Tips
- Use a clear, well-lit source face with minimal occlusion (no sunglasses or heavy shadows) for the best results.
- The source face should be front-facing or near-frontal — extreme angles may reduce swap quality.
- Shorter clips process faster — for long videos, consider trimming to the key segments first.
- Higher-quality source videos produce sharper, more detailed face swaps.
