## FAQ
**How is Vidu Q3 Pro priced?**
Vidu Q3 Pro is billed per second of output video at the selected resolution. Audio is included at no extra cost, and failed generations are never charged.

**Is this the official Vidu Q3 Pro?**
Yes. Requests run on Shengshu's Vidu Q3 Pro through official API access, at a lower price than Vidu's own list price.

**How is it different from Vidu Q3 Turbo?**
Q3 Pro is the full-quality model: more detail and more cinematic motion, at a higher price per second. Q3 Turbo renders faster and costs less — use it for drafts and social clips, and Q3 Pro for final shots.

**Can I use the output commercially?**
Yes, subject to Vidu's terms of use and our Terms of Service.

Vidu Q3 Pro is developed by Shengshu. CheaperGen provides API access and does not own the model.
