How to use HeyGen's Video Maker
Creating your video with our AI-powered video maker is fast, intuitive, and flexible. Here's how you go from idea to final video:
No Crew. No Cuts. Just Your AI Video Agent at Work.
Agent is the first creative engine built to transform a single prompt into a complete video.
Prompt-Native Video Creation
Agent is the first creative engine built to transform a single prompt into a complete video. You describe the idea. Agent returns a fully constructed, publish-ready asset. There is no need to write scripts, manage assets, or piece together content manually.
End-to-End Video Generation
Agent handles the full video creation process. It writes a clear and compelling script based on your idea, selects images that match the tone and message, adds natural and emotion-aware voiceover, applies edits and transitions for polished pacing, and finalizes subtitles, timing, and rhythm for clarity and performance.
Built with Structure and Intent
Unlike traditional workflows that rely on timelines and manual assembly, Agent constructs videos from the ground up. Each output is intentionally designed to match your goal. From messaging and rhythm to scene flow and audience fit. The result is a coherent and purpose-driven video.
