HeyGen is what I use for client explainer videos now, here is my actual experience after three months

I do marketing for a handful of small business clients. Explainer videos used to mean either hiring someone or convincing one of the business owners to get in front of a camera, which was always a struggle. HeyGen changed that workflow for me and I want to give an honest account of how.

The Video Agent is the starting point. You type a basic description of what you want, a product explainer, a company intro, a social media ad, and it generates a full plan including script, avatar selection and background music. From that plan you go into the AI Studio to customize.

The avatar library has a wide range of realistic options and the quality is good enough that clients who see the videos are generally not bothered by the fact that it is not a real person. You can also create a custom avatar from a short video recording if a client specifically wants their face in the content.

The template selection covers the formats I use most: social media, e-commerce, breaking news style. Brand kits keep everything consistent across different videos for the same client.

Translation is built in and maintains the original voice across languages, which has been useful for one client who sells to both English and Spanish-speaking markets. The Canva and HubSpot integrations save some steps in the wider workflow.

One thing to know: the more you put into the prompt at the Video Agent stage, the less you have to fix in the editor afterward. Vague prompts produce generic results.
