Seedance 2 Fast on VdoBloom currently costs 4.8 credits per second at 480p and 10 credits per second at 720p, so a 5-second 480p draft is 24 credits ($1.20) and a 10-second 720p clip is 100 credits ($5.00) at the Lite rate of $0.05 per credit. Those are promotional rates passed straight through from our upstream provider; the standard table they revert to is 6.2 credits per second at 480p and roughly 13.2 at 720p, and both sets of numbers are published below so you can plan either way. The price for your exact settings is always shown on screen before you generate, and that figure is the one that gets charged.

Seedance 2 Fast exists for a specific economic reason: it keeps the full 4-to-15-second duration ladder and all six aspect ratios of the flagship, caps resolution at 720p, and returns results faster — so you can run the ten generations it takes to find a shot without spending flagship money on nine failures.

Seedance 2 Fast credit costs, tier by tier

Duration is selectable in one-second steps from 4 to 15 seconds, in 16:9, 4:3, 1:1, 3:4, 9:16 or 21:9. Aspect ratio never changes the price; only resolution and duration do. Billing is strictly per second of output, so any duration not listed can be worked out from the rate.

Tier	Per second	4 s (minimum)	5 s	10 s	15 s (maximum)
480p, current rate	4.8 credits	19 cr — $0.95	24 cr — $1.20	48 cr — $2.40	72 cr — $3.60
720p, current rate	10 credits	40 cr — $2.00	50 cr — $2.50	100 cr — $5.00	150 cr — $7.50
480p, standard rate	6.2 credits	26 cr — $1.30	32 cr — $1.60	62 cr — $3.10	93 cr — $4.65
720p, standard rate	13.2 credits	52 cr — $2.60	66 cr — $3.30	132 cr — $6.60	196 cr — $9.80

Read the gap between the two pairs of rows as your planning margin. Even at the standard rate, a 15-second 720p Seedance 2 Fast render stays under 200 credits — which is what a 10-second 720p Seedance 2.5 clip costs on its own.

The cheaper tier: generating with a reference video

Supplying a reference video drops the rate again, to 2.8 credits per second at 480p and 6 credits per second at 720p. This is the cheapest way to get Seedance 2 Fast output.

Resolution	Per second (with reference video)	4 s	5 s	10 s	15 s
480p	2.8 credits	11 cr — $0.55	14 cr — $0.70	28 cr — $1.40	42 cr — $2.10
720p	6 credits	24 cr — $1.20	30 cr — $1.50	60 cr — $3.00	90 cr — $4.50

One rule to internalise: on the reference-video tier, the billed duration is input plus output. VdoBloom measures your uploaded clip and charges the same per-second rate for its length. A 10-second 720p render driven by a 6-second reference video therefore costs 6 × (10 + 6) = 96 credits ($4.80), not 60. Input length is capped at 15 seconds for this model. The fix is simple and worth doing every time: trim the reference clip to only the seconds you need before you upload it.

Plain image-to-video and text-to-video both bill at the standard rates in the first table — the discount applies specifically to reference-video generations. If you are animating a photograph of a real person, you must have that person’s consent before generating.

A realistic session budget

Here is what the model is actually for. You have a concept and no idea which prompt phrasing lands. Run six 5-second 480p variations at 24 credits each: 144 credits, $7.20. Shortlist two, re-run them at 720p for 5 seconds each: 100 credits. Take the winner to 15 seconds at 720p: 150 credits. Total 394 credits, about $19.70, and every experiment happened at draft cost.

Compare that with developing the same idea directly on the flagship. Six 5-second 480p passes on Seedance 2 cost 38 credits each — 228 credits instead of 144 for identical drafting work, before you have rendered anything you intend to keep. Because Fast shares the flagship’s durations and all six aspect ratios exactly, a composition proven at 480p in a 21:9 frame re-renders at higher resolution in the same frame with no re-composition.

Fast against the rest of the family

Model	Top resolution	Max duration	10 s at 720p	Best for
Seedance 2 Mini	720p	15 s	33 cr — $1.65	Highest-volume throwaway passes
Seedance 2 Fast	720p	15 s	100 cr — $5.00	Iteration you may ship as-is
Seedance 2	4K	15 s	163 cr — $8.15	Short finals needing 4K
Seedance 2.5	1080p (10-bit)	30 s	200 cr — $10.00	Long-form and colour-critical finals

The honest reading of that table: if you are only ever going to run a clip once and 720p is fine, Fast is the sensible default. If you will run it twenty times, drop to Mini. If the deliverable genuinely needs 4K or more than 15 seconds, Fast cannot do it at any price and you should go straight to the flagship or to 2.5.

What your free credits cover

New accounts get 10 credits, no card required. On Seedance 2 Fast that falls just short: the cheapest generation is 11 credits (4 seconds, 480p, with a reference video) and the cheapest text or image render is 19 credits. If you want to spend the free balance inside this family before paying, Seedance 2 Mini starts at 6 credits for a 4-second 480p clip. There is more on free generation on the free AI video generator page.

What the credit price includes

Credits are the whole cost. A paid plan downloads Seedance 2 Fast output watermark-free with commercial rights — no export fee, no licence upgrade, no per-resolution unlock. Failed renders are refunded automatically. One-time credit packs start at $2.49 for 75 credits and never expire, which suits a drafting model like this one better than a subscription does if your work comes in bursts. Plans, packs and the annual rates are on the pricing page, and you can start a render on the image-to-video page.

Frequently asked questions

How much does a 5-second Seedance 2 Fast video cost?

24 credits ($1.20) at 480p and 50 credits ($2.50) at 720p at current rates; 32 and 66 credits at the standard rates. With a reference video the cost falls to 14 and 30 credits, before the reference clip’s own seconds are added.

Why does Seedance 2 Fast cost less than Seedance 2?

It caps resolution at 720p and returns faster. Durations, aspect ratios and content filtering are identical to the flagship, so the saving comes from resolution and compute time, not from a reduced feature set.

Is the discounted rate permanent?

No. It is a limited-time provider rate, which is why the standard rates are published in the same table above. Whatever the rate on the day, the credit cost shown before you press generate is what gets deducted.

Does a longer reference video cost more?

Yes. On the reference-video tier the billed duration is input seconds plus output seconds at the same per-second rate, capped at 15 input seconds. Trimming the source clip is the single most effective way to cut the bill.

Can I develop a prompt on Fast and finish on Seedance 2?

That is the intended workflow. The two models share the same 4-to-15-second ladder and the same six aspect ratios, so a prompt and framing validated at 480p transfers to the flagship for a 1080p or 4K final without rewriting anything.
