Video Face Swap
Seamlessly swap faces in videos with just a few clicks. Upload your video and a reference face image, and the model will intelligently replace faces while preserving natural motion, lighting, and expressions. No complex editing software required.
Why It Looks Great
- Natural blending: Automatically matches skin tone, lighting, and shadows for seamless face integration.
- Expression preservation: Retains the original facial movements, emotions, and lip sync from the source video.
- Temporal consistency: Minimizes flickering and artifacts across frames for stable, realistic results.
- Multi-face support: Handle videos with multiple people — target specific faces by index.
- High fidelity output: Maintains video quality with sharp facial details and smooth edges.

- For videos with multiple people, use target_index to precisely control which face gets swapped.
- Keep the reference face angle similar to the faces in the video for more natural blending.

- Processing time varies based on video length and current queue load.
- For videos longer than 10 minutes, split into segments and process separately.
