What is HeyGen's AI Video Generator?
HeyGen's AI video generator turns a script, URL, photo, or rough idea into a finished video, without a camera, crew, or editor. Write what you want, avatars perform it, AI B-roll fills it in, voiceover narrates it, and captions sync to every word. Text in, image in, video out.
Everything you need from an AI Video Generator
Prompt to finished video, all in Video Agent
Skip the blank canvas. Describe the AI-powered video you want, and Video Agent handles scripting, scenes, avatar, voice, pacing, and captions. Pick a length and orientation, add images or a PDF, and approve the plan before it renders. Available in HeyGen, ChatGPT, and via API. Start from 100+ templates for ads, social, demos, and explainers, or turn a deck into a cut with PDF to video.
Text to video and image to video, built in
The best AI video models live inside the editor, not in another tab. Seedance 2.0 turns a line of text into smooth, multi-shot clips with motion that holds up. Veo 3.1 sets a product shot, portrait, or brand image in motion, or bridges two reference images into a transition or logo reveal. Pick the model that fits the shot, drop the clip into your scene, and keep working. No extra subscription, no second login, no exporting and re-uploading.
The most realistic avatars, powered by Avatar V
Record yourself once on a webcam for 15 seconds. Avatar V learns how you move, gesture, and speak, then performs in any outfit, any setting, any look, with phoneme-level lip sync in 177+ languages and dialects. You look and sound like you in every scene, up to three avatars per shot. Or animate a photo with Avatar IV, Kling, Runway, or Hailuo.
Direct your video shots like a filmmaker
Set location, camera, music, and references in their own fields, then describe the action. Dolly, push, orbit, crane, or handheld, and stack up to three shots in one prompt. Drop in a reference image or clip and the AI matches the lighting, wardrobe, pacing, and gestures. Name the look, cinematic, documentary, anime, or vintage, without writing a 200-word prompt. The closest thing to a real film camera without one.
Add voices, sound, and captions in one place
Layer in AI voiceovers in 177+ languages and dialects, clone your own voice, or one-click sync any character to any audio. Describe the sound you want and Seedance 2.0 scenes arrive with it. Add licensed music and sound effects, then auto-caption every clip as SRT or burned in.
Edit videos in AI Studio, no reshoots required
Tell Video Agent what to change, the background, the third scene, that one image, and it updates the plan without regenerating everything. Want frame-level control? Open a copy in AI Studio. AI does the rest when you don't. The full editor sits next to the generator, so you move from rough cut to polished asset without switching tools.

Learn More About the AI Video Generator
What are AI video generators?
AI video generators are tools that use artificial intelligence to create videos from a simple text prompt, images, or scripts. They handle editing, visuals, and voiceover automatically, so you don't need video editing skills to produce professional results.
How does HeyGen’s AI video generator work?
HeyGen's AI video generator turns a prompt, script, or PDF into a finished video. Video Agent writes the script and builds the scenes, your avatar presents, and B-roll, voice, and captions go on top.
What is the best AI video generator?
HeyGen is a leading AI video generator built for professionals and marketers. It lets you generate AI videos using ready-made templates or text prompts in any format for social media, sales, or business content.
What kinds of videos can I make with HeyGen?
HeyGen's AI video generator handles explainers, product demos, ads and UGC-style clips, training, sales outreach, and social clips for TikTok, Reels, and Shorts, plus cinematic scenes and trailers.
How to create an AI video of yourself?
Upload a short clip or reference image of yourself, then type your script in HeyGen. The platform generates a video with realistic AI motion and voice. You can adjust the format, add scenes, and customize the output for explainer videos or social clips.
Can I turn an image into a video?
Yes, two ways. Upload a photo of a person, add a script, and HeyGen turns it into a talking video. Or hand a product shot or brand image to Veo 3.1 and it brings the still to life as B-roll.
Is HeyGen a free AI video generator?
Yes. HeyGen's free plan gives you 3 Video Agent videos a month, up to 1 minute each, plus 500+ stock avatars. Paid plans remove the watermark and add voice cloning, with Seedance 2.0 from Pro.
How long does it take to generate an AI video?
A HeyGen video is usually ready in minutes. B-roll clips render in a few, and a full Video Agent video takes about 5 to 10 times its length, so a one-minute video lands in 5 to 10 minutes.
How long can an AI video be?
Most AI video generators stop at 15 seconds a clip. HeyGen keeps going: up to 30 minutes on Creator and Pro, 60 on Business, and no cap on Enterprise.
What resolution and aspect ratios can I export?
HeyGen exports MP4 at 720p on Free, 1080p on Creator, and 4K on Pro and above, with captions as SRT or burned in. Pick 16:9, 9:16, or 1:1 to fit YouTube, TikTok and Reels, or feeds.
Which AI video models can I use in HeyGen?
HeyGen runs Seedance 2.0 for multi-shot B-roll and avatar scenes, Veo 3.1 for image to video, Nano Banana for stills, and Kling, Runway, and Hailuo for photo avatar motion, all in one subscription.
How much creative control do I get over AI-generated videos?
Full creative control. Prompt the whole video at once or direct it scene by scene with a visual, script, and duration for each, then review the plan and iterate until it's right.
How do I write a good prompt for an AI video?
Good AI video prompts start with a good script, because the presenter's words carry the video. Add a tone line, not timestamps. For B-roll, name the setting, action, camera, and sound.
Do I need to download software or have editing experience?
No. HeyGen runs in your browser with nothing to install. Describe the video once and Video Agent builds it. Want changes? Tell the agent in chat, no timeline skills needed.
Can I make cinematic scenes or short films with HeyGen?
Yes. HeyGen's Avatar Shots turn a scene description into a cinematic clip with generated audio. Call the camera moves and mood in your prompt, stack shots like a storyboard, then cut in B-roll.
Can I use HeyGen videos for commercial projects?
Yes. Videos created on paid plans can be used for commercial projects, from ads to client deliverables, with flexible export options for every platform and format.
Can HeyGen generate images as well as videos?
Yes. Built-in image generation powered by Nano Banana and Seedream creates AI images for scene backgrounds or thumbnails. Animate them with image-to-video in the same project.
