Vidu Q4 clip price at 3, 6, 10 and 16 seconds, promo vs regular

A Vidu Q4 image-to-video clip costs $0.0945 for 3 seconds at 540p and $4.368 for 16 seconds at 4K during the 30% promotion, which fal's page says runs until November 30 (read 2026-10-09). After that the same clips are $0.135 and $6.24. Vidu Q4 is not in Sume's video catalog as of the code read on 2026-10-09, so there is no Sume price to put next to it.

What are the per-second rates?

What does one clip cost by length?

Multiply the rate by the seconds. Each cell shows promo / regular.

How big is the November 30 step?

The regular rate is the promo rate divided by 0.7, so every tier rises 42.9% when the promotion ends. A 10-second 1080p clip goes from $0.84 to $1.20. A 100-clip batch at 10 seconds and 1080p is $84 now and $120 after.

Where does Sume fit?

Sume lists other rows for the same job: Wan 3.0 (2 to 30 s, $0.0625 to $0.25 per second at 480p to 1080p) and Gemini Omni Flash 1.1 (3 to 10 s, $0.0375 to $0.375 per second at 360p to 4K), both at provider list x 1.25 per the Video Router docs. Those are different models, so compare a test clip, not just the rate.

How should I plan a Vidu Q4 test around the deadline?

Because the promotion is 30% off, the cheapest time for an experiment is before November 30. A 20-clip test of 6 seconds each at 1080p is $10.08 now and $14.40 afterwards; at 4K it is $32.76 now and $46.80 afterwards.

The page also says clips run 3 to 16 seconds, so a 16-second shot is a single request at any listed resolution.

• Decide the resolution you ship at, then test only that tier and one tier below.
• Write down the date you read the rate; the page can change before you finish.
• Keep the same input images when you re-run on another model, so the comparison is about the model.
