LightX2V

LightX2V is an AI digital human and multimodal content production platform. Originally a lightweight, high-performance open-source inference framework for image and video generation, it has now become an online workbench for creators.

The core capability is digital human video: with character assets, a spoken script, and a voice ready, you can generate a digital human presenter video with natural lip-sync, up to 5 minutes per clip, with support for multiple digital humans in the same frame and over 600 built-in AI voices. It also offers image-to-video, video lip-sync, character replacement, motion transfer, and image-to-image.

With Canvas, you can connect assets, models, speech recognition, digital avatar generation, and other steps into a reusable workflow, and it also provides APIs and Skills for developers to integrate. A free mode lets you generate one video first to try out the results; it’s suitable for teams producing knowledge-based talking-head videos, product sales explainers, and corporate training videos.

If you want to create continuous storylines rather than single shots, TVLab offers serialized short-drama novels updated one chapter per episode, and both character settings and storyboard scripts can be copied with one click—making it easy to produce episodic series with video tools like this.
