How it works

San Xuan Tang
Upload a floor plan, fill in orientation and occupant details, and receive a structured report with an annotated plan, position mapping and suggested remedies.
Vidu Q4 AI Video Generator
Vidu Q4 generates video and synchronised audio together, so dialogue, lip sync and sound effects come out of the same render as the picture, starting from an image or a set of references.

Stands out for

Vidu Q4 AI Video Generator
Picture and sound come from one generation, and up to 15 reference images plus 3 voice clips can be combined in a single request, so a multi-shot scene stays consistent without stitching separate takes.
