Provider rates
fal publishes one per-second price per resolution for both Vidu Q4 routes. Until November 30, 2026 it charges 30% less: $0.0315/s at 540p, $0.0665/s at 720p, $0.084/s at 1080p, $0.133/s at 2K and $0.273/s at 4K. After that the list rates apply. ShengShu’s own announcement quotes launch pricing from $0.014 per second on Vidu’s platform; plans and regions differ.

This studio prices credits against fal’s list rates, not the temporary discount, so prices will not jump on December 1. The exact quote appears before you submit, and confirmed failures return the credits.
- 540p: 2 credits per second (5 s = 10 credits)
- 720p: 3 credits per second (5 s = 15 credits)
- 1080p: 4 credits per second (5 s = 20 credits)

How to spend less
Draft at 540p and the shortest length that shows the idea, fix the prompt, then render the keeper once at the resolution you need. Reference images and voice clips are free to add.
