Seedance 2.0 Specs: Official Model, Access Channels & Site Settings
Seedance 2.0 output specs, separated by who states them. ByteDance official model capability, official access channels, what this site (seedance2-video.com) currently offers, and items that are not yet verified — so model facts and site settings never get mixed up.
Direct answer
The Seedance 2.0 specs page should summarize visible generation limits such as resolution, clip duration, aspect ratios, audio behavior, reference inputs, and access channels. Because model capabilities and API products can change, this page should distinguish Seedance2Video observations from official ByteDance or Volcengine claims and keep every JSON-LD fact visible in the page body.
Operator disclosure
Seedance2Video is operated by Vividra Labs LLC as an independent third-party interface. It is not ByteDance, Doubao, Jimeng, or Volcengine Ark. ByteDance / Volcengine sources remain the authority for official model and API facts.
Verified date

Seedance 2.0 specs at a glance
ByteDance's official Seedance 2.0 technical report documents 4–15 second generations at 480p and 720p native resolution, with text, image, audio, and video inputs and joint audio-video generation. Official open-platform reference limits list up to 3 videos, 9 images, and 3 audio clips. A separate Seedance 2.0 Fast version exists. seedance2-video.com is an independent interface operated by Vividra Labs LLC; it exposes its own settings — including durations and resolutions that can differ from the official report — which are listed below as site settings, not as ByteDance model ceilings.

Native audio specifications
Seedance 2.0 uses a unified audio-video generation architecture. ByteDance describes joint generation and dual-channel audio, including stronger alignment among dialogue, sound effects, background music, and visuals. Those statements do not establish that each element is delivered as a separate editable track. On seedance2-video.com, native audio is exposed as a per-generation toggle and audio files can also be supplied as references. See the native-audio workflow →
API pricing (Volcengine Ark)
Volcengine Ark is the official developer route, but this review did not verify a stable first-party per-second price for Seedance 2.0. Token rates and eligibility can change, so confirm current billing in the official Ark console or documentation before budgeting. Pricing on seedance2-video.com is separate, uses site credits, and must not be presented as ByteDance API pricing. See this site’s current pricing →

People also ask
What resolution does Seedance 2.0 output?▾
ByteDance's official Seedance 2.0 technical report documents 480p and 720p as the native resolutions. 1080p output, where available, is a platform setting of the service you use — for example, seedance2-video.com offers 1080p on its Standard model — not a stated official model ceiling.
How long can a Seedance 2.0 clip be?▾
ByteDance's official Seedance 2.0 technical report documents a 4–15 second generation range. What a given site or channel actually exposes can be narrower — seedance2-video.com offers 4–15 seconds on Standard and 4, 8, or 12 seconds on Seedance 2.0 Fast.
What inputs does Seedance 2.0 accept?▾
Seedance 2.0 accepts text, image, audio, and video as inputs and supports joint audio-video generation. Which modalities an access channel exposes can vary.
Does Seedance 2.0 generate audio?▾
Yes. Seedance 2.0 supports joint audio and video generation in a single pass, and ByteDance describes dual-channel audio. Whether music, SFX, dialogue, or voiceover are delivered as separate editable tracks is not verified from a first-party source.
What are the Seedance 2.0 reference input limits?▾
ByteDance's open-platform reference limits list up to 3 video references, 9 image references, and 3 audio references. Individual UIs may expose lower limits — seedance2-video.com accepts up to 5 images, 3 videos, and 3 audio files.
Frequently asked questions about Seedance 2.0 specs
Are Seedance 2.0 specs the same across all access channels?▾
Not assumed. ByteDance official model capability, official access routes, and third-party interfaces can expose different durations, resolutions, and limits. Check the channel you actually use rather than assuming uniform capability.
Does Seedance 2.0 support 4K or 1080p output?▾
ByteDance's official technical report documents 480p and 720p native resolution. 1080p is offered as a platform setting on some services — including seedance2-video.com Standard — but is not stated by ByteDance as an official model ceiling.
Is there a Seedance 2.0 Fast version?▾
Yes. A Seedance 2.0 Fast version exists as a separate, faster variant. On seedance2-video.com it supports 480p/720p at 4, 8, or 12 seconds, which is narrower than the Standard model on the same site.
How do I access the official Seedance 2.0 documentation?▾
The authoritative references are ByteDance Seed's technical report and the Volcengine Ark API documentation at volcengine.com/product/ark. Third-party pages (including this one) cross-check against those primary sources.
What is the frame rate of Seedance 2.0 output?▾
This site does not expose a frame-rate setting, and a fixed frame rate is not verified from the official technical report. Do not treat any specific fps number as a stated official fact.
What aspect ratios does Seedance 2.0 support?▾
The official technical report used for this review does not state a universal aspect-ratio list for every channel. On seedance2-video.com, Standard offers 16:9, 4:3, 1:1, 3:4, 9:16, and 21:9; Fast also offers an Adaptive option. These are site settings, not a claim about every ByteDance access route.
How much does the Seedance 2.0 API cost?▾
Volcengine Ark bills developer access according to its current platform terms, but this review did not verify a stable first-party per-second figure. Check the official Ark console or documentation before budgeting. seedance2-video.com uses separate site credit pricing shown on its pricing page.
What is multi-reference conditioning in Seedance 2.0?▾
Multi-reference conditioning means using several input assets to guide composition, subject identity, motion, camera language, or sound. The Team Seedance technical report lists open-platform caps of up to 9 images, 3 videos, and 3 audio clips. Individual interfaces may expose different limits.
Can I generate videos longer than 12 seconds?▾
Yes, depending on the route. The official technical report documents 4–15 second generations. On seedance2-video.com, Standard supports up to 15 seconds while Fast offers 4, 8, or 12 seconds. For longer sequences, generate multiple clips and edit them together.
