HeyGen Launches Veo 3.1 for Consistent Avatar Videos

• HeyGen integrates Veo 3.1 to create consistent avatar videos that maintain voice, movement, and appearance.
• Users select avatars and voices on the homepage banner to generate scenes via text prompts.
• Features include cinematic motion with dynamic camera angles and professional movements.
• Avatars support scene-by-scene control for customizing environments, actions, and atmospheres.
• Generated avatars save for reuse in unlimited videos with seamless transitions between settings.

HeyGen announced the release of Veo 3.1, a video generation tool that allows users to create consistent avatar videos rather than isolated clips.

This update integrates with HeyGen’s avatar technology to preserve a user’s real voice, movement, and style in every production.

According to the company’s email announcement, users access the feature through the “Veo 3.1 avatar video” option on the homepage top banner. They choose an avatar and voice, then input prompts to describe scenes.

The system generates content with cinematic motion, including dynamic camera angles and professional movements.

HeyGen states that every output saves as a reusable avatar, enabling consistent use across unlimited videos. This builds on Veo 3.1’s capabilities for high-quality visuals, now enhanced by avatar consistency.

The announcement, sent directly from the HeyGen Team, emphasizes that the tool blends a user’s real tone into the generated motion for authentic results.

Access and Core Features

Users start by navigating to the homepage banner for “Veo 3.1 avatar video.”

They select an avatar—digital representations that mimic human-like appearances – and pair it with a voice option.

Text prompts guide the creation of each scene, controlling elements like environments, actions, and atmospheres.

Cinematic motion refers to advanced video techniques that simulate professional camera work, such as panning or zooming, to add depth.

HeyGen’s email details that seamless transitions ensure the avatar moves naturally between settings, maintaining one identity across multi-scene videos. For example, the avatar can appear in different outfits, styles, or environments while keeping the same voice and look.

This consistency stems from generating the avatar once in Veo 3.1, then reusing it without regeneration. The company notes compatibility with standard web browsers, requiring no specific hardware beyond a stable internet connection, as per their platform guidelines.

Voice and Character Consistency

Voice consistency allows users to choose their own audio tone, which HeyGen integrates into Veo 3.1’s output.

The system blends this real voice with the tool’s cinematic effects, avoiding synthetic alterations. As described in the announcement, this feature supports endless storytelling by preserving the user’s true vocal style.

For character consistency, the avatar retains its appearance and mannerisms across productions. Users can create videos in varied contexts, such as changing scenes from indoor to outdoor, without losing the core identity.

HeyGen highlights that this enables unlimited videos, saved directly in the platform for easy access. The announcement from the HeyGen Team confirms these elements work together to produce professional-grade content, powered by Veo 3.1’s version 3.1 engine, which focuses on high-fidelity video synthesis.

Additional Tools and Resources

Veo 3.1 also appears in the “Generate Video Assets” section for creating B-roll – supplementary footage like cinematic backgrounds or transitions.

Users select this option to produce standalone clips that complement avatar videos. For guidance, HeyGen provides a walkthrough video by team member Brandon, available on X at this link.

The video demonstrates prompt usage, avatar selection, and scene customization. HeyGen’s announcement positions this as an advancement in video generation, combining Veo 3.1’s visual strengths with their avatar expertise.
