Video Face Swap
The Video Face Swap block replaces a face in a video file with a face from a provided image.
Swap faces in a video using a source image
The Video Face Swap block replaces a face in a video file with a face from a provided image. It takes a video URL and a face image URL as its primary inputs, along with a target index that specifies which face in the video to replace when multiple faces are present. The result is saved to a variable of your choosing via the destinationVar parameter, which stores the output as a URL pointing to the processed video.
The block uses a standard engine and includes an optional intermediateAsset flag. When set to true, the output asset is created but kept hidden from the gallery, which is useful when the swapped video is an intermediate step in a larger pipeline rather than a final deliverable.
This block fits into workflows that involve video personalization, content localization, or automated video production. For example, it can be used in pipelines that generate customized video content at scale, where a single video template needs to be adapted with different faces for different recipients or use cases.
What you can build
Real-world workflows powered by the Video Face Swap block.
Personalized Video Greetings
Replace a placeholder face in a video template with a specific person's face to generate individualized greeting or onboarding videos at scale.
Localized Marketing Content
Swap the on-screen presenter's face in a marketing video to match a regional spokesperson without re-shooting the original footage.
Training Video Customization
Adapt a standard training video by replacing the instructor's face with a company-specific representative for white-label or branded deployments.
Entertainment and Fan Content
Generate creative video content by substituting faces in existing clips as part of an entertainment or fan-engagement application.
Avatar-Based Video Pipelines
Use the block as an intermediate step in a pipeline that generates avatar-driven video content, keeping the swapped output hidden from the gallery until final processing is complete.
Multi-Face Video Targeting
Target a specific individual in a multi-person video using the targetIndex parameter to swap only the intended face while leaving others unchanged.

What are the required parameters for this block?
The block requires a videoUrl pointing to the source video, a faceImageUrl providing the replacement face, a targetIndex indicating which face in the video to replace, and a destinationVar specifying the variable name where the output URL will be stored.
What does the block return?
The block saves the URL of the processed video to the variable defined in destinationVar. This URL can then be referenced by downstream blocks in the workflow.
What does the targetIndex parameter do?
The targetIndex is a number that identifies which face to replace when the video contains multiple faces. This allows you to target a specific individual rather than swapping all detected faces.
What is the intermediateAsset option used for?
When intermediateAsset is set to true, the output video asset is created but hidden from the gallery. This is useful when the face-swapped video is a mid-pipeline artifact that feeds into further processing steps rather than being a final output.
What kinds of workflows commonly use this block?
This block is commonly used in video personalization pipelines, automated content generation workflows, and multi-step video production flows where a face-swapped video serves as either a final deliverable or an intermediate asset passed to additional processing blocks.
