Do I need a HeyGen API key for AI face swapping?▼

Yes, you need a HeyGen API key. You must configure the HEYGEN_API_KEY environment variable to authenticate with the HeyGen API and execute the face swapping processing.

Can I use a JPG image to replace a face in an MP4 video?▼

Yes, you can use a JPG image as the source face to replace a face in an MP4 video. The skill processes the source image and target video to generate a personalized output.

What is the HeyGen API used for in video editing?▼

The HeyGen API is used for AI-driven video processing, specifically executing face swaps through its /v1/workflows/executions endpoint. It allows you to integrate face replacement into video editing workflows.

How does personalized video creation work with AI processing?▼
