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 completes it, a voice-over narrates it and captions synchronise with every word. Text in, image in, video out.
Everything you need from an AI video generator
From prompt to finished video, all within Video Agent
Forget the blank canvas. Describe the AI-powered video you want, and Video Agent handles the script, scenes, avatar, voice, pacing and captions. Choose a length and orientation, add images or a PDF, then approve the plan before rendering. Available in HeyGen, ChatGPT and via API. Start with more than 100 templates for adverts, social media, demos and explainers, or turn a presentation into an edited video with PDF to video.
Text-to-video and image-to-video, built in
The best AI video models are built into the editor, rather than sitting in another tab. Seedance 2.0 turns a line of text into smooth, multi-shot clips with convincing motion. Veo 3.1 animates a product shot, portrait or brand image, or connects two reference images to create a transition or logo reveal. Choose the model that suits the shot, add the clip to your scene and carry on working. No additional subscription, no separate login, and no need to export and upload again.
Our most lifelike 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, setting or look, with phoneme-level lip-syncing in
Direct your video shots like a film-maker
Set the location, camera, music and references in their own fields, then describe the action. Dolly, push, orbit, crane or handheld, and combine up to three shots in a single prompt. Add a reference image or clip, and the AI will match the lighting, wardrobe, pacing and gestures. Specify the look — cinematic, documentary, anime or vintage — without writing a 200-word prompt. It is the closest thing to a real film camera, without needing one.
Add voices, audio and captions in one place
Add AI voiceovers in more than 177 languages and dialects, clone your own voice, or synchronise any character to any audio with one click. Describe the sound you want, and Seedance 2.0 scenes will include it. Add licensed music and sound effects, then automatically caption every clip as an SRT file or with captions burnt in.
Edit videos in AI Studio, with no need for reshoots
Tell Video Agent what to change – the background, the third scene or that one image – and it updates the plan without regenerating everything. Want frame-level control? Open a copy in AI Studio. AI handles the rest when you do not need that level of control. The full editor sits alongside the generator, so you can move from rough cut to polished asset without switching tools.

Find Out 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 voice-over automatically, so you do not need video-editing skills to achieve professional results.
How does HeyGen’s AI video generator create videos?
HeyGen's AI video generator turns a prompt, script or PDF into a finished video. Video Agent writes the script and creates the scenes, your avatar presents, and B-roll, voice-over and captions are added.
Which AI video generator is best?
HeyGen are a leading AI video generator for professionals and marketers. You can create AI videos from ready-made templates or text prompts in any format for social media, sales or business content.
What types of videos can I create with HeyGen?
HeyGen's AI video generator handles explainer videos, product demonstrations, adverts and UGC-style clips, training, sales outreach and social media clips for TikTok, Reels and Shorts, as well as cinematic scenes and trailers.
How can you create an AI video of yourself?
Upload a short clip or reference image of yourself, then enter your script in HeyGen. The platform generates a video with realistic AI movement and voice. You can adjust the format, add scenes and customise the output for explainer videos or social media clips.
Can I turn an image into a video?
Yes, there are two ways. Upload a photo of a person, add a script and HeyGen will turn it into a talking video. Alternatively, give Veo 3.1 a product shot or brand image and it will bring the still image to life as B-roll.
Can I use HeyGen as an AI video generator for free?
Yes. HeyGen's Free plan gives you three Video Agent videos per month, each up to one minute long, plus more than 500 stock avatars. Paid plans remove the watermark and include voice cloning, with Seedance 2.0 available from the Pro plan.
How long does it take to create an AI video?
A HeyGen video is usually ready within minutes. B-roll clips render in just a few minutes, whilst a complete Video Agent video takes roughly 5 to 10 times its duration to produce, meaning a one-minute video will be ready in 5 to 10 minutes.
How long can an AI-generated video be?
Most AI video generators limit clips to 15 seconds. HeyGen offers up to 30 minutes on Creator and Pro, 60 minutes on Business, and no limit on Enterprise.
Which resolutions and aspect ratios can I export?
HeyGen exports MP4 video at 720p on Free, 1080p on Creator and 4K on Pro and above, with captions supplied as SRT files or burnt into the video. Choose 16:9, 9:16 or 1:1 to suit YouTube, TikTok, Reels or social feeds.
Which AI video models are available in HeyGen?
HeyGen use 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 within one subscription.
How much creative control do I have over AI-generated videos?
Complete creative control. Prompt the entire video at once, or direct it scene by scene with visuals, a script and a duration for each. Then review the plan and refine it until it is right.
How can I write an effective prompt for an AI video?
Effective AI video prompts begin with a strong script, as the presenter's words drive the video. Add a line describing the tone rather than timestamps. For B-roll, specify the setting, action, camera and sound.
Do I need to download any software or have editing experience?
No. HeyGen runs in your browser, with nothing to install. Describe the video once and Video Agent will create it. Want to make changes? Tell the agent in the chat – no timeline editing skills are required.
Can I create cinematic scenes or short films with HeyGen?
Yes. HeyGen's Avatar Shots turn a scene description into a cinematic clip with generated audio. Specify the camera movements and mood in your prompt, arrange shots as a storyboard, then add B-roll.
Can I use HeyGen videos for commercial projects?
Yes. Videos created on paid plans can be used for commercial projects, from adverts 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 using image-to-video in the same project.
