How I’d Use It: The “One-Man Agency” Workflow

If I were launching a new service alone and needed a professional explainer video, I wouldn’t hire an expensive agency. Instead, I would use HeyGen or InVideo.

Here is my specific strategy:

• Script from URL: I would paste my product’s landing page URL into the AI to automatically generate a script that highlights key features.
• Avatar Selection: I would choose a “friendly-looking” AI avatar to act as the narrator, giving the video a human touch without hiring an actor.
• Screen Recording Overlay: This is the pro tip. I would overlay actual screen recordings of my software while the AI avatar talks in the corner (Picture-in-Picture), rather than relying only on stock footage.

Bottom line: This method allows me to create a “Trustworthy” brand image that looks like it cost $5,000, but actually cost $30 and took 2 hours.
