How HeyGen’s AI transforms text, presentations, and audio into ready-to-use videos

2–4 minutes

The HeyGen platform uses artificial intelligence to automate video production, offering tools that generate narration, create virtual presenters, and translate content into multiple languages. With it, businesses can convert documents, slides, and even audio recordings into audiovisual materials ready for training, marketing, or internal communication.

Turn scripts into videos with virtual presenters

A written text can be converted into a video narrated by a digital avatar. The user selects an available character or creates a custom model, defines the voice, language, and presentation style. The result is a video that combines AI-generated movements and expressions, ideal for tutorials, product launches, or corporate communications.

For example, an HR professional can update new employee onboarding materials without re-recording each module, simply by editing the script and generating a new video.

Create videos from a simple instruction

The Video Agent feature takes a description of the desired content and automatically creates the script, images, narration, subtitles, and transitions. The user reviews the plan before generation and can adjust specific sections using the platform’s editor.

For instance, a sales manager can request a video presentation of a new product, specify its benefits, and receive a ready-to-share material for the team.

Adapt videos for other languages

The translation tool can convert an existing video into up to ten languages, generating new narration and, in some modes, lip synchronization. The platform also provides subtitles and controls to maintain consistency in product names and brand terms.

For companies with international teams, this feature simplifies the adaptation of training, demonstrations, and communications. However, it’s advisable to review the translation, especially when the material contains technical terms or regulatory information.

Convert slide presentations into narrated videos

PowerPoint or PDF files can be imported and transformed into video scenes featuring avatars and AI-generated narration. This allows analysts and managers to repurpose presentation of results or training materials, creating a narrated version for later consultation or distribution to different teams.

The final content should be reviewed to ensure the narration correctly explains graphics, maintains the order of information, and does not omit important caveats.

Create videos from static images and audio files

HeyGen also animates photographs and converts audio recordings into videos that include avatars, subtitles, and visual elements. A specialist can transform a recorded technical explanation into a video with a virtual presenter, while an image can serve as the basis for a video with synchronized speech.

These capabilities help repurpose existing materials and adapt formats for different channels, such as training, presentations, and social media.

What to consider before using HeyGen

  • Human review remains essential: verify the accuracy of information, the pronunciation of technical terms, the naturalness of the narration, and the quality of the translation.
  • Check the limits and conditions of the contracted plan, which may vary depending on the resource used.
  • When production involves the image or voice of real people, respect applicable authorizations and privacy rules.
  • Test the final result, review each piece of information, and evaluate whether the video meets the target audience’s needs before publishing.

The choice of functionality depends on the objective: producing presentations, adapting training, reaching audiences in other languages, or repurposing existing content.

Artificial intelligence is also changing the skills required in the job market. A Pre-MBA course in AI offered by Saint Paul, with four online practical classes, costs R$ 37 and teaches applications of the technology in business.
