AI Video Generator

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
