Do not invent a subscription price. Read the pricing page for the current plans. The rules below are the studio's per-second credit cost.

## Per second

Vidu Q4 generation is billed per output second, by resolution:

credits = duration seconds × per-second rate

| Resolution | Credits/second | 5s clip |
| --- | --- | --- |
| 540p | 9 | 45 |
| 720p | 19 | 95 |
| 1080p | 24 | 120 |
| 2K | 38 | 190 |
| 4K | 78 | 390 |

Duration is clamped to 3-16 seconds. Both image-to-video and reference-to-video use the same table - reference inputs do not add a surcharge in this studio.

Writing a prompt and choosing settings does not spend credits. Generation does, after sign-in.

Commercial use of generated video depends on this site's terms and on the model provider's usage policies. See https://vidu-q4.com/terms.
