Seedance 2.0 vs Seedance 1.5
Seedance 1.5 is the cheaper of the two on the only render both models price. 5s at 1080p is 315 credits on Seedance 2.0 against 100 on Seedance 1.5. So on cost alone the answer is Seedance 1.5, and the only reason to spend the difference on Seedance 2.0 is a capability Seedance 1.5 does not have. In practice, take Seedance 2.0 if you need one continuous clip longer than 12 seconds, and Seedance 1.5 if you want to see it on your own product before you pay anything.
We run Seedance 2.0 (ByteDance) and Seedance 1.5 (ByteDance) ourselves, on our own provider accounts, inside the same studio and off the same credit balance. Everything below is read out of the catalogue that prices your renders, so the numbers are the ones your account is actually charged. What you will not find here is a quality verdict: we hold no benchmark that would make one honest, so every claim on this page is a capability or a price you can check.
Seedance 2.0 vs Seedance 1.5: the specs
Every cell below is read from the catalogue that our generator and our billing run on, so it is what you get and what you are charged, not what a vendor page advertises. Two rows are worth reading carefully: where the render runsis the platform we actually dispatch to, which is not always the one a model’s Replicate name implies, and how the length is set separates the models you give a duration to from the ones whose clip runs as long as the speech does.

Like for like: what the same render costs
Only the clip lengths and resolutions BOTH models price appear here. Comparing a 5 second render against a 15 second one and calling the gap a price difference is the most common way these comparisons go wrong, so rows that do not line up exactly are left out.
| Render | Seedance 2.0 | Seedance 1.5 | Difference |
|---|---|---|---|
| 5s at 1080p | 315 credits | 100 credits | 215 credits cheaper on Seedance 1.5 |
Credit costs, not dollars: what a credit costs you depends on the plan, and all three plans are listed on the pricing page.
Which one to pick
Each line below traces back to a single difference in the tables above. Where a model has no measurable advantage, that is what it says.
Pick Seedance 2.0 if
- You need one continuous clip longer than 12 secondsSeedance 2.0 runs to 15s in a single call. Seedance 1.5 caps at 12s, so anything longer has to be cut together from more than one render.
- The deliverable has to be 4KSeedance 2.0 prices a 4K tier, from 660 credits for 5s at 4K. Seedance 1.5 tops out at 1080p.
- One shot has to combine several things you already have, a product, a face, a backgroundSeedance 2.0 carries up to 9 reference images into a single render. Seedance 1.5 carries one, so the rest has to come from the prompt.
Pick Seedance 1.5 if
- You want to see it on your own product before you pay anythingSeedance 1.5 runs during the free 3-day trial. Seedance 2.0 is on paid plans only, so trying it means starting a plan first.
- Cost is the deciding factorSeedance 1.5 is cheaper on the only render both models price, by 215 credits a render.
- You want the cheapest possible render to test an idea onSeedance 1.5 starts at 100 credits (5s at 1080p). The cheapest thing Seedance 2.0 sells is 140 credits.
- You are buying seconds of finished video rather than a specific clip lengthSeedance 1.5 is the better rate at every resolution the two share (1080p): 20 credits a second against 63 at 1080p.
What they have in common
A comparison that manufactures a difference is worse than no comparison, so here is where Seedance 2.0 and Seedance 1.5 genuinely match.
- Both are ByteDance models.
- Both need a reference image. Neither will render from a prompt on its own, and the input carries up to 9 images on Seedance 2.0 and one image on Seedance 1.5.
- Both come back with their own audio, so neither needs a separate voice pass in the chain.
- Both price 1080p.
- Neither has an announced end date.
- The renders go to different places: Seedance 2.0 is dispatched to BytePlus as undefined and Seedance 1.5 to Replicate as bytedance/seedance-1.5-pro. Both are our own accounts and both bill the same credit balance.
- Both spend from that one balance on every plan, so moving a campaign from Seedance 2.0 (from 140 credits a render) to Seedance 1.5 (from 100) costs you nothing but the credit difference.

One credit balance, every model
Seedance 2.0 and Seedance 1.5both spend from the same balance, so a plan is not a commitment to one of them. Here is what each plan’s credits buy on the two models on this page, measured in seconds of finished video.
| Plan | Credits a month | Seedance 2.0 | Seedance 1.5 |
|---|---|---|---|
| Starter $49 a month, or $34 billed annually | 5,000 | 37 to 178 seconds | 245 to 250 seconds |
| Growth $99 a month, or $69 billed annually | 12,000 | 90 to 428 seconds | 588 to 600 seconds |
| Agency $199 a month, or $139 billed annually | 25,000 | 188 to 892 seconds | 1,225 to 1,250 seconds |
The low end of each range is the model’s dearest priced tier and the high end its cheapest, both from the tables above, so a month spent entirely at 4K sits at the bottom and a month of 720p drafts near the top. Mixing models moves it in between. On a paid plan, credits are the only limit: no cap on how many renders you make and no per-model licence. Annual billing is 30% off (Starter saves $180 a year, Agency $720). Seedance 1.5 runs during the free 3-day trial. Seedance 2.0 needs a paid plan.
Seedance 2.0 vs Seedance 1.5: frequently asked questions
Which is cheaper, Seedance 2.0 or Seedance 1.5?
Seedance 1.5 is the cheaper of the two on the only render both models price. 5s at 1080p is 315 credits on Seedance 2.0 against 100 on Seedance 1.5. So on cost alone the answer is Seedance 1.5, and the only reason to spend the difference on Seedance 2.0 is a capability Seedance 1.5 does not have.
How long can a single Seedance 2.0 or Seedance 1.5 clip be?
Seedance 2.0 caps at 15s and prices 5s, 10s and 15s. Seedance 1.5 caps at 12s and prices 5s, 8s and 12s. Both are per-render limits, so a longer ad is several renders cut together rather than one long generation.
What resolutions do Seedance 2.0 and Seedance 1.5 render at?
Seedance 2.0 is priced at 720p, 1080p and 4K. Seedance 1.5 is priced at 1080p. Those are the tiers you can actually buy, not the tiers the vendors advertise.
How many reference images can Seedance 2.0 and Seedance 1.5 take?
Seedance 2.0 carries up to 9 reference images into one render and Seedance 1.5 carries one. That matters when a shot has to combine things you already have, a product, a hand, a background, in the same frame: with one image the rest has to be described in the prompt and re-rolled until it lands. The counts are read from the request each model is actually sent, not from a vendor spec sheet.
Do Seedance 2.0 and Seedance 1.5 need a reference image?
Both do. Neither Seedance 2.0 nor Seedance 1.5 will render from a text prompt alone, so you need a product shot or an avatar frame first.
How do Seedance 2.0 and Seedance 1.5 handle audio?
The same way. Seedance 2.0 generates its audio in the same pass as the picture, so there is no separate voice step to run or pay for, and Seedance 1.5 works identically. Neither one needs a voice model bolted on afterwards.
Do I need a separate plan for each model?
No. Every plan is one credit balance that spends on any model we run, so the same subscription renders a Seedance 2.0 test at 140 credits and a Seedance 1.5 test at 100 and you compare them on your own footage. There is no per-model licence, and on a paid plan credits are the only thing that runs out rather than a render count.
Can I try Seedance 2.0 and Seedance 1.5 on the free trial?
One of them. Seedance 1.5 runs during the free 3-day trial, from 100 credits a render against a 250 credit per-render ceiling. Seedance 2.0 is not available on the trial and needs a paid plan. We would rather say so on this page than have the product refuse after you have signed up.
Where do these Seedance 2.0 and Seedance 1.5 numbers come from?
From the accounts the renders actually run on. Seedance 2.0 is dispatched to BytePlus as undefined and Seedance 1.5 to Replicate as bytedance/seedance-1.5-pro, both ours. The 9 priced tiers listed for Seedance 2.0 and the 3 priced tiers for Seedance 1.5 are read at build time from the same price table that debits your balance when a render finishes, and the capabilities come from the record the generator reads to build each request, so a reprice or a new tier rewrites this page instead of leaving a stale number on it. What you will not find is a quality or realism score for either one: we hold no benchmark that would make one honest.
