How Script-to-Video Works
Script-to-video features in just a few clicks
Paste your script or upload a brief, and the AI-powered text-to-video engine handles complete video generation, including narration, captions, transition graphics and matching premium stock footage. These script-to-video features transform scripts into production-quality videos.

Lifelike AI avatars present your script
Choose an Avatar V that delivers every line of your script with a natural performance, expressive detail, and visual polish. It offers complete upper-body movement, consistency across multiple angles, and stability for long-form content, ensuring a five-minute lesson is as compelling as a hook.

Voice cloning and AI voice-overs
Turn your scripts into polished videos with voice-overs in your own voice or a studio-quality AI voice from the library. AI voice cloning captures your tone from a short sample, then keeps it consistent across every script and language you publish.

Over 177 languages with lip-synced captions
Translate your script into over 177 languages with AI lip sync that matches mouth movements to the new audio. AI tools also automatically generate captions in every language, enabling the same script to reach a global audience without re-recording a single line in the studio.

Write the script, then generate the video
Need to create engaging video scripts? The video script generator instantly drafts a structured, on-brand script from a single topic or rough brief. Add the draft directly to the script-to-video workflow, and AI script generation will produce a polished, presenter-led video.

Use cases
Short-form content creation used to take hours of filming and editing. Paste your script to create videos with AI voiceovers, captions, animation, and a presenter ready to publish across every social feed in a vertical 9:16 format.
Explainer videos used to need a scriptwriter, voice talent, and a designer. Now write the script, pick an AI talking head or talking avatar, and create professional-quality explainer videos your audience finishes in two minutes.
Faceless creators lose weeks every month to voiceover and video editing. The script-to-video tool converts scripts into videos with an AI voice generator take, B-roll, transitions, and background music. Publish a narrated tutorial without filming.
A marketer's brief sits waiting for crews and editors. Drop your script into the free script to video generator, swap the presenter and brand colors, and walk out with a professional video the same afternoon you wrote the brief.
Course creators lose days to filming and re-shoots every time a lesson changes. Paste a lesson script, generate a presenter-led module, and tweak the timeline in the AI video editor to edit videos without re-recording.
A blog post or presentation lives in one channel only and dies there. Turn blog posts into storyboards and a video script, run them through the script-to-video feature, and republish the idea on YouTube, LinkedIn, and Instagram without rewriting.
How it works
Create script-to-video content in four clear steps, from raw text to a polished video that is ready to share.
Paste your script into the editor, upload a file, or create a video script using a topic prompt.
Choose an AI avatar or your own digital twin. Select a voice, language and brand template.
Add captions, replace stock footage, refine the pacing, and apply your brand colours, fonts, graphics and logo.
Preview and render the video project, download it as an MP4 file, and share it on YouTube, TikTok, or any LMS.




Script-to-video AI automatically converts written content into a finished video. It brings your script to life by creating a storyboard, generating AI voice-overs, matching stock footage or an AI avatar, and exporting a polished, high-quality video that you can publish anywhere. Once the script is ready, turn it into a complete show with HeyGen's AI podcast generator.
