Both modes offer 540p, 720p, 1080p, 2K, and 4K, with whole-number lengths from 3 to 16 seconds. Defaults are 720p and 5 seconds. Higher settings do not guarantee flawless results.
What does prompt expansion do?▼

How are video credits calculated?▼
Vidu Q4 multiplies the resolution’s per-second credit rate by video length. Both modes use the same rates. Review the estimate before submitting; shorter clips use fewer credits at the same resolution.
