FAQs

What is an explainer video?

An explainer video is a short and engaging piece of content that clearly presents a company’s product, service, or idea. They are a common part of sales and marketing strategies, and you will often see them on landing pages, social media, and inside promotional campaigns. The goal is to capture attention, communicate a message, and drive engagement.

How do you make an explainer video?

1. Write a video script: Plan exactly what you want to say and use the script to structure the flow of your video.
2. Use a video tool to create the video: Instead of hiring a production company, use a video maker to simplify the process.
3. Review and refine: Watch the video to make sure the message is clear and aligned with your goal. Adjust text, templates, visuals, or sound if needed.
4. Publish and track performance: If something needs to change later, simply return to your project and make quick edits to create an updated version.
