ByteDance Seedance 2.5 Pricing: Real Credit Costs Per Second

Seedance 2.5 on VdoBloom is billed per second of output: 11.2 credits per second at 480p, 25.2 credits per second at 720p and 63.2 credits per second at 1080p — so a 10-second 720p clip costs 252 credits, which is $12.60 at the Lite plan rate of $0.05 per credit. Nothing about that pricing is hidden behind a “contact us” tier or a per-model subscription. You hold one credit balance, the exact cost for the settings you have chosen is displayed before you press generate, and if the render fails the credits come back.

This page breaks down every tier of ByteDance Seedance 2.5 with the real numbers from VdoBloom’s pricing table, including the lower reference-video rate that most write-ups miss, and the one billing rule that can surprise you.

The credit-to-dollar conversion used here

Every figure below converts at $0.05 per credit, which is the Lite plan rate: $15 a month for 300 credits. That is the honest reference point, not the cheapest one. One-time credit packs start at $2.49 for 75 credits, which works out at roughly $0.033 per credit and never expires, and annual billing at the 2,000-credit Pro tier ($49/month) brings the effective rate down to about $0.025. In other words, the dollar figures in the tables are a ceiling for most accounts, not a floor.

Seedance 2.5 text-to-video and image-to-video pricing

Seedance 2.5 generates from 4 to 30 seconds in one-second steps — the longest duration ladder in the Seedance family — at 480p, 720p or 1080p, in six aspect ratios (16:9, 4:3, 1:1, 3:4, 9:16 and 21:9). Because billing is strictly per second, you can price any duration yourself by multiplying the rate. These are the standard rates, which apply to text prompts and to image-driven generations alike.

Resolution	Per second	5 s	10 s	15 s	30 s
480p	11.2 credits	56 cr — $2.80	112 cr — $5.60	168 cr — $8.40	336 cr — $16.80
720p	25.2 credits	126 cr — $6.30	252 cr — $12.60	378 cr — $18.90	756 cr — $37.80
1080p (10-bit)	63.2 credits	316 cr — $15.80	632 cr — $31.60	948 cr — $47.40	1896 cr — $94.80

The floor is the 4-second render: 45 credits ($2.25) at 480p, 101 credits ($5.05) at 720p and 253 credits ($12.65) at 1080p. The ceiling is a 30-second 1080p clip at 1,896 credits. That spread — roughly 42× between the cheapest and most expensive single generation — is why picking the right tier matters more on Seedance 2.5 than on almost any other model in the catalog.

The reference-video tier: a lower rate, on more seconds

Seedance 2.5 charges a materially lower per-second rate when you supply a reference video rather than starting from text or a still image. This is the tier people mean when they talk about Seedance style transfer. The rates drop to 6.8 credits per second at 480p, 15.2 at 720p and 38 at 1080p.

Resolution	Per second (reference + output)	5 s from a 2 s reference	10 s from a 5 s reference	15 s from a 5 s reference	30 s from a 10 s reference
480p	6.8 credits	48 cr — $2.40	102 cr — $5.10	136 cr — $6.80	272 cr — $13.60
720p	15.2 credits	107 cr — $5.35	228 cr — $11.40	304 cr — $15.20	608 cr — $30.40
1080p	38 credits	266 cr — $13.30	570 cr — $28.50	760 cr — $38.00	1520 cr — $76.00

The rule that surprises people: on the reference-video tier, billing counts input plus output seconds, not output alone. VdoBloom measures the length of the clip you upload and charges the same per-second rate for it. So a 10-second 720p render driven by an 8-second reference video is not 152 credits — it is 15.2 × (10 + 8) = 274 credits, or $13.70. The upstream provider bills us that way, and we pass the real number through rather than quietly absorbing it or capping quality instead. Input length is capped at 30 seconds for Seedance 2.5.

The practical consequence: trim your reference clip before you upload it. Cutting a 20-second source down to the 6 seconds you actually need saves 14 seconds of billing at full rate — 213 credits at 720p, over $10 of real money on a single render.

Worked example: a 15-second vertical ad

Say you want a 15-second 9:16 product spot at 720p, from a text prompt. That is 378 credits, or $18.90 — more than a month of Lite. Most people should not spend it that way. The sensible sequence is to draft at 480p first: three 15-second 480p passes cost 168 credits each, 504 credits total, and let you settle composition, pacing and framing. Then one 720p finish at 378 credits. Total 882 credits. Alternatively, run the drafting stage on a cheaper family member and reserve every Seedance 2.5 credit for finals.

Where the free 10 credits actually get you

New accounts get 10 credits free with no card. Be clear-eyed about what that buys on this model: nothing. The cheapest possible Seedance 2.5 generation is 45 credits, so the free balance does not reach the 4-second 480p floor. If you want to spend your free credits on the Seedance family before paying anything, use Seedance 2 Mini, where a 4-second 480p clip costs 7 credits — you get a real Seedance render, with a real result to judge, for free.

When a different Seedance tier is the better buy

Seedance 2.5 is not automatically the right spend. Seedance 2 tops out at 15 seconds but adds a 4K tier the 2.5 model does not have, at 83.2 credits per second (832 credits for 10 seconds). If your deliverable is short and needs genuine 4K, Seedance 2 wins on capability regardless of price. If you need anything longer than 15 seconds, or you want 10-bit 1080p colour, Seedance 2.5 is the only member of the family that offers it. And if your job is iteration volume rather than final quality, the Fast and Mini tiers exist precisely so you are not burning 63.2 credits a second on experiments.

Model	Max duration	Top resolution	Cheapest 10 s render
Seedance 2.5	30 s	1080p (10-bit)	112 cr — $5.60 (480p)
Seedance 2	15 s	4K	76 cr — $3.80 (480p)
Seedance 2 Fast	15 s	720p	48 cr — $2.40 (480p)
Seedance 2 Mini	15 s	720p	16 cr — $0.80 (480p)

What the credits include

A paid plan downloads Seedance 2.5 output without a watermark and with commercial rights, so the credit cost is the whole cost — there is no separate export fee, licence upgrade or resolution unlock. Credits bought in one-time packs never expire. You can start a render from the text-to-video page, and the Seedance prompt library is a good place to find prompt structures that work on this family before you spend 1080p credits testing your own. Full plan and pack details are on the pricing page.

Frequently asked questions

How much does a 10-second Seedance 2.5 video cost?

112 credits at 480p ($5.60), 252 credits at 720p ($12.60) and 632 credits at 1080p ($31.60), using the Lite rate of $0.05 per credit. With a reference video the per-second rate is lower, but the reference clip’s own seconds are billed too: from a 5-second reference the same 10 seconds is 102, 228 or 570 credits.

Why is my reference-video render costing more than the table says?

Because that tier bills input plus output duration. The per-second rate is lower, but your uploaded clip counts toward the total at the same rate. Trim the source video to the shortest usable length before uploading.

What is the cheapest way to test Seedance 2.5?

A 4-second 480p render at 45 credits. On the reference-video tier the same output from the shortest reference accepted (2 seconds) is 42 credits, because the reference clip’s seconds are billed at 6.8 credits each too. Below that, drop to Seedance 2 Mini, which starts at 7 credits.

Do Seedance 2.5 credits cost less on an annual plan?

Yes. The $0.05 per credit figure used throughout this page is the Lite monthly rate. Annual billing at the 2,000-credit Pro tier brings the effective rate to roughly $0.025 per credit, which halves every dollar figure in the tables above.

Does Seedance 2.5 support vertical and cinema-wide framing?

Yes. Six aspect ratios are available at every resolution and duration: 16:9, 4:3, 1:1, 3:4, 9:16 and 21:9. Aspect ratio does not change the credit cost — only resolution and duration do.
