HeyGen

HeyGen is currently one of the most widely used AI digital human video tools. Its core capability lies in using a given piece of content to create an avatar that resembles you both in appearance and voice; thereafter, by inputting text, it can generate videos in which this avatar performs lip-syncing.

Another widely utilized feature of this tool is video translation: users can upload a Chinese-language audio recording, and the system will generate versions in English, Spanish, and other languages. The lip movements in the original video will be automatically aligned with the new text in these languages, rather than simply adding a new soundtrack. Teams that create content for international markets rely heavily on this feature.

The product also offers a wide range of pre-made virtual avatars and templates, allowing users to create content without revealing their faces.

The interface is in English, and it offers a monthly subscription service with a free trial quota available. It is important to pay attention to the regulatory requirements regarding digital humans and voice cloning in different regions; make sure to obtain the necessary authorization before using these services commercially.

If you want to create a continuous storyline rather than individual scenes, TVLab offers serialized short-form dramas that are updated chapter by chapter. The character settings and storyboards can be easily copied with just one click, making it very convenient to use such video tools for creating continuous series.
