What is 有言?
With 3D digital humans as the main visual elements in videos, users can input scripts, select characters and scenes, and then orchestrate character voices, expressions, movements, and camera shots. The official website offers multiple creative entry points—starting from scratch, using templates, AI-generated scripts, or PPTs—making it ideal for turning existing documents or presentation materials into videos.
The platform offers capabilities such as character customization, multilingual voiceovers, scene transitions, shot editing, and post-production packaging. When the script or PPT content changes, you can continue making edits within the original project; the available options for characters, scenes, and voice tones must be confirmed based on your current account and workspace.
Typical use cases include corporate training, course instruction, product presentations, and promotional content. When producing such materials, first verify the script’s facts, pronunciation, and pacing, then review each segment to ensure that subtitles, animations, and expressions are well-coordinated. If you use custom avatars, photos, or audio, be sure to obtain the necessary permissions.
