Vidu Q3 Pro is the higher-fidelity variant of ShengShu's Vidu Q3, released in January 2026. It generates clips from 1 to 16 seconds at 540p, 720p or 1080p from text, a single start frame, or a first and last frame pair. Generated audio with dialogue and sound effects is on by default and does not change the price. Text-to-video offers five aspect ratios (16:9, 9:16, 4:3, 3:4, 1:1), prompts go up to 2,000 characters, and a seed makes results repeatable.

Best for

  • Very short 1-3 second loops and stingers
  • 16-second single-shot scenes
  • Morphing from one keyframe to another
  • Clips with dialogue and effects where sound is included in the price

Prompting tips

  • aspect_ratio applies to text-to-video only; with images attached, the frames set the format.
  • One image gives image-to-video; two images give a first-to-last-frame transition.
  • Audio costs nothing extra, so describe the sound you want: "rain on a tin roof, distant thunder".
  • Use seed to hold a result steady while you change wording; -1 means random.
