Seedance 2.5: 30-second storytelling, audio and picture generated together
ByteDance's next-generation audio-video joint generation model — built for 30-second narratives with precise reference control.
Seedance 2.5 doubles the single-clip ceiling to 4–30 seconds and raises the multimodal reference budget to 30 images, 10 videos and 10 audios per request. On APIPod you call the official full-capability model at 5% off list price through one unified API — discount and special-offer routes share the same endpoint, and plain public URLs are reviewed for you automatically.

Seedance 2.5 vs 2.0 — what changed?
Same Seedance DNA; twice the runtime and a much larger reference budget.
Move to Seedance 2.5 when…
- The story needs more than 15 seconds — vlogs, ads, dialogue scenes and one-take action up to 30s
- Consistency demands a full reference pack: character sheets, locations, motion clips and voice tracks in one request
- You want native audio — spoken lines, ambience and music generated with the picture
- You need the official full-capability model at the lowest per-token cost available
Stay on Seedance 2.0 when…
- Final delivery needs 4K ultra HD — the 2.5 discount tier tops out at 1080P; use the 2.0 standard tier for 4K (now live on APIPod)
- You rely on the fast / mini / lite tiers for specialized speed or cost profiles
- Existing 2.0 prompts already produce the shots you need at 5–15s
Spec comparison at a glance
Seedance 2.5 extends the 2.0 contract instead of replacing it — the model field is the only change most integrations need.
| Spec | Seedance 2.5 | Seedance 2.0 |
|---|---|---|
| Duration per clip | 4–30s (default 4s) | 4–15s (default 5s) |
| Resolution tiers | Discount: 480P / 720P / 1080P; special-offer: 720P only | Up to 4K |
| Reference images | Up to 30 | Up to 9 |
| Reference videos | Up to 10 | Up to 3 |
| Reference audios | Up to 10 | Up to 3 |
| Native audio | Yes — on by default | Yes |
Both generations ship through APIPod's full-capability pipeline: media URLs are reviewed by the asset service before submission, so plain public URLs work in requests. Billing is token-based on successful tasks only — see the pricing page for live rates.
Official list price · 5% off
Official pricing reference
Seedance 2.5 bills by tokens on the official side: token consumption per second scales with resolution, and a video reference is billed for the reference duration together with the output duration at a lower unit price.
| Resolution | Tokens per second | Without video reference | With video reference |
|---|---|---|---|
| 480P | 9,607.5 tokens/s | $10.7 /M tokens · ≈ $0.103/s | $6.4 /M tokens · ≈ $0.062/s |
| 720P | 21,600 tokens/s | $10.7 /M tokens · ≈ $0.231/s | $6.4 /M tokens · ≈ $0.138/s |
| 1080P | ≈ 38,500 tokens/s | $10.7 /M tokens · ≈ $0.412/s | $6.4 /M tokens · ≈ $0.246/s |
With-video billing counts reference-video duration plus output duration as tokens. Official example — 10s reference + 10s output: 480P $1.23, 720P $2.76 per clip.
List prices from the official Seedance 2.5 pricing page; APIPod's discount tier bills at 5% off. The special-offer routes (seedance-2.5-lite-*) output 720P only — 1080P is not available there. Your actual rates on APIPod are shown on the pricing page.
What Seedance 2.5 is built for
Longer narratives, better control — the official positioning, delivered through one API.
30-second one-take stories
Write the clip as timed beats — setup, action, payoff — and Seedance 2.5 holds blocking, wardrobe and scene logic across the full take. Extend twice for even longer cuts.
Reference-driven consistency
Up to 30 images, 10 videos and 10 audios per request: character identity, product appearance, motion paths and voice tracks each get an explicit job in the prompt.
Audio-video joint generation
Dialogue, ambience and music are generated together with the visuals and land on the frame — including invented-language performances and perfectly timed SFX.
Professional camera language
Orbits, whip pans, speed ramps, handheld tracking and invisible-cut staging: name the move and the model executes it with cinematic framing.
Real prompts, real output
Community cases from the APIPod prompt library — every card shows the actual video and the prompt skeleton that produced it. Copy them, swap in your subject, and ship.
T2V · 30s action
Aerial storm action spectacle
A dialogue-free 30-second aerial battle written as five timed beats — speed ramps, whip pans and match cuts through volumetric storm clouds.
Prompt excerpt
30-second cinematic aerial action spectacle, high-budget feature film, aggressive speed ramps, rapid match cuts, whip pans, rotating camera moves, volumetric storm clouds, ocean spray… [0–5s] dark storm clouds gather above a vast ocean; a battleship cuts through enormous waves; a fighter emerges from the clouds…
R2V · Identity lock
1990s Tokyo chase and rollover crash
Four labeled reference sheets hold character, wardrobe and vehicle identity through a full-speed anamorphic chase that ends in a rollover explosion.
Prompt excerpt
Preserve the exact identity and wardrobe of the male target @target_character_sheet and the female assassin @assassin_character_sheet. Use @landcruiser_sheet as the identity reference for the black 1990s Toyota Land Cruiser, @kawasaki_ninja_sheet for the green Ninja motorcycle…
R2V · Native audio
Alien commander battlefield dialogue
Two reference portraits become a blockbuster battlefield exchange performed entirely in an invented alien language — generated audio, generated picture.
Prompt excerpt
Image1 is the alien commander and leader; Image2 is the soldier alien. The commander gives orders to the soldier on a battlefield. A dialogue scene between the two — the speech must be entirely in an invented alien language. A battle scene from a blockbuster film, with cinematic camera moves and angles.
T2V · Multi-scene consistency
Hawaii tropical travel vlog
One traveler held across eight distinct scenes — city, beach, ocean, market, sunset, hotel — with handheld travel-diary movement and golden-hour light.
Prompt excerpt
Create a cinematic 30-second tropical travel vlog featuring the same 20-year-old East Asian woman with dark hair throughout every scene. Keep her facial identity, hairstyle, natural makeup and body proportions consistent. Authentic handheld travel-diary movement, candid performance, soft golden-hour light…
Recommended workflow: draft wide, finalize once
1) Draft at 480P
Validate composition, timing and reference roles cheaply — and test a 5–10s opening before committing to the full 30s.
2) Borrow proven prompts
Start from the community templates in the prompt library; each detail page explains the beat structure so you can rebuild the rhythm for your subject.
3) Finalize at 720P / 1080P
Rerun the winning prompt at 720P or 1080P with the same reference pack; fix a single failed beat by editing only that time range instead of regenerating.
4) One API, every Seedance
Switch between 2.5 and 2.0 tiers by changing the model field — auth, billing and observability carry over.

}Seedance 2.5 FAQ
What is Seedance 2.5?
Seedance 2.5 is ByteDance's next-generation audio-video joint generation model, built for 30-second storytelling. It generates video with synchronized native audio, follows timed-beat prompts, and accepts large multimodal reference packs for identity, motion and voice control.
How long can a Seedance 2.5 video be?
A single generation runs 4–30 seconds (default 4s). For longer narratives, write the clip as timed beats and extend the result — the official guidance allows extending twice for longer cuts.
What is the difference between Seedance 2.5 and 2.0?
2.5 doubles the per-clip ceiling from 15s to 30s and raises reference limits from 9 images / 3 videos / 3 audios to 30 / 10 / 10. On resolution, the discount routes output 480P / 720P / 1080P and the special-offer routes (seedance-2.5-lite-*) are locked to 720P, while Seedance 2.0 supports up to 4K. Prompt structure, native audio and the asset-review pipeline are shared.
Does Seedance 2.5 support 1080P or 4K?
Yes for 1080P. The discount routes (seedance-2.5-t2v / i2v / r2v) output 480P / 720P / 1080P; the special-offer routes (seedance-2.5-lite-*) are locked to 720P. For 4K masters, use the Seedance 2.0 standard tier (4K now live on APIPod).
Does Seedance 2.5 generate audio?
Yes. Audio-video joint generation is on by default (generate_audio=true): dialogue, ambience and music are produced together with the visuals. You can disable it per request, and steer voices and sound with reference audio clips on the r2v route.
How do I call Seedance 2.5 through the API?
POST to /v1/videos/generations with model set to seedance-2.5-t2v, seedance-2.5-i2v or seedance-2.5-r2v. The task is asynchronous — poll the returned task ID until status is completed. Media URLs you pass are reviewed by the asset service automatically, so plain public URLs just work.
