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 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 1080P+ — the 2.5 family tops out at 720P; the 2.0 standard tier ships 1080P today with 4K rolling out
- 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; 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
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 |
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. The special-offer routes (seedance-2.5-lite-*) output 720P only — 1080P is not available on the 2.5 family. 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
Rerun the winning prompt at 720P 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 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?
No. The discount routes output 480P and 720P, and the special-offer routes (seedance-2.5-lite-t2v / i2v / r2v) are locked to 720P. For higher-resolution masters, use the Seedance 2.0 standard tier (1080P today, 4K rolling out 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.
