AI Video Generator

AI video generators are tools that use artificial intelligence to create videos from a simple text prompt, images, or scripts. They automatically handle editing, visuals, and voice-over, 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 are added.

HeyGen is a leading AI video generator designed 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 explainer videos, product demos, ads and UGC-style clips, training, sales outreach, and social media clips for TikTok, Reels, and Shorts, as well as cinematic scenes and trailers.

Upload a short clip or reference image of yourself, then enter 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 media clips.

Yes, there are two ways. Upload a photo of a person, add a script, and HeyGen turns it into a talking video. Or provide Veo 3.1 with a product shot or brand image, and it will bring the still image to life as B-roll.

Yes. HeyGen's Free plan gives you three Video Agent videos per month, up to one minute each, plus more than 500 stock avatars. Paid plans remove the watermark and add voice cloning, with Seedance 2.0 available starting with Pro.

A HeyGen video is usually ready in minutes. B-roll clips render in just a few minutes, while a full Video Agent video takes about 5 to 10 times its length to render, so a one-minute video is ready in 5 to 10 minutes.

Most AI video generators stop at 15 seconds per clip. HeyGen keeps going: up to 30 minutes on Creator and Pro, 60 minutes on Business, and no limit on Enterprise.

HeyGen exports MP4 video at 720p on Free, 1080p on Creator, and 4K on Pro and higher plans, with captions provided as SRT files or burned into the video. Choose 16:9, 9:16, or 1:1 to suit YouTube, TikTok, Reels, or social feeds.

HeyGen uses Seedance 2.0 for multi-shot B-roll and avatar scenes, Veo 3.1 for image-to-video, Nano Banana for still images, and Kling, Runway, and Hailuo for photo avatar motion, all in one subscription.

Full creative control. Prompt the entire video at once, or direct it scene by scene with visuals, a script, and a duration for each scene. Then, review the plan and refine it until it's right.

Effective AI video prompts begin with a strong script, since 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.

No. HeyGen runs in your browser, with nothing to install. Describe the video once, and Video Agent builds it. Want to make changes? Tell the agent in the chat—no timeline skills needed.

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 like a storyboard, then add 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 using image-to-video in the same project.
