How To Use HeyGen AI Video Agent (2026 Tutorial For Beginners)

After signing into HeyGen, the dashboard lays out every available option. Build a video scene by scene, generate one from a prompt, create an avatar video from a script, design a custom AI avatar, translate any video, or start with a template. Over on the left-hand navigation panel, there’s Video Agent, and that’s where this demo begins. The workspace opens a clean, guided layout. At the top, AutoAvatar determines who appears on screen, whether that’s a digital twin, a public avatar from HeyGen’s library, or one built entirely from scratch. AutoVoice handles the audio side, offering options to clone an existing voice, design a custom one, import from a third party, or browse HeyGen’s built-in library.

An auto style brings a collection of visual styles to choose from. Below is the text prompt box, where the concept takes shape. Attachments, brand systems, or knowledge files can be uploaded alongside the prompt. Prompt ideas are also surfaced for anyone looking for a creative starting point. Duration can be set, and the format can be toggled between portrait and landscape. Plus, SeedDance 2.0 can be enabled to bring cinematic depth to avatar scenes. And once the prompt is ready, two paths appear, where you can chat and plan the video step-by-step, or click AutoGenerate. For this demo, the prompt is set to a tutorial on building a humanoid robot from scratch.

The style, avatar, and music are each described in the prompt to guide Video Agent on the desired look, presence, and tone of the final video. And once the Generate button is clicked, Video Agent takes over. A chat box on the left displays progress in real time, starting the workflow, mapping out the next steps, then building each scene one by one. Next, the builder appears on the right with the full video plan laid out with the script and style already applied. Avatars can be swapped, and voices can be changed, the credits required are displayed up front so everything is accounted for.

Next to the builder, a Videos tab shows the video as it’s being generated. The Assets tab breaks down everything Video Agent has created. The avatar, the voice, individual media assets, and design elements ready to be used. Once complete, each scene can be reviewed and edited individually. Caption styles can be changed to match the desired tone or branding, and when everything looks right, the video is ready to download or share directly. So here’s the final output. I’m here to guide you through every step of this build. It all starts with design. We focus on center of mass and degrees of freedom to ensure stability and fluid movement.

As we assemble the frame, every bolt must be precise. Rigid construction is the backbone of reliable robotics. Programming brings it to life. We’ll implement a PID control loop to coordinate every motor in real time. Finally, the test. We’ll verify sensor calibration and step sequence logic before our first walking attempt. Precision and patience pay off. You’ve built your first humanoid. Now, the real experimentation begins. To demonstrate another practical application, here’s a quick second demo with a completely different use case. A customer onboarding video explaining a platform’s key features. The style, avatar, and music are each tailored to match the tone and branding of the content, showing how the same effortless process delivers an entirely different outcome.
