Building a Product Demo Around a One-Photo AI Video Workflow

I recently experimented with making the product demo itself demonstrate the product.
The video uses an AI-generated presenter alongside actual TalkPix UI footage.
The workflow shown is intentionally minimal:
Upload one portrait
Enter text or upload audio
Click Generate
Receive a talking-video output
There is no video recording or manually created facial animation involved in the core workflow.
The demo also cuts to the actual interface while the presenter explains each step, which helps communicate the product faster than a conventional feature list.
The celebrity-inspired presenter is an AI-generated fan concept and does not represent an endorsement.
