Seedance 2.0 outputs at up to 1080p native resolution. This is an improvement over the 1.x line, which maxed at 720p (with Lite at 480p). All three main access channels — Volcengine Ark API, seedance2-video.com, and Doubao — deliver 1080p.
How long can a Seedance 2.0 clip be?▾
Seedance 2.0 clips can be up to 12 seconds long, with a minimum of 4 seconds. This compares to 8 seconds maximum in Seedance 1.0 (and 5 seconds in the Lite tier).
What aspect ratios does Seedance 2.0 support?▾
Seedance 2.0 supports five aspect ratios: 16:9 (landscape), 9:16 (vertical/mobile), 1:1 (square), 4:3, and 3:4. The 1.x line only supported 16:9 and 9:16.
Does Seedance 2.0 generate audio?▾
Yes. Seedance 2.0 generates audio natively in the same pass as the video — no separate audio step. Supported audio types: background music, sound effects, voiceover narration, and lip-synced dialogue. Output is dual-channel stereo with separate tracks.
How much does the Seedance 2.0 API cost?▾
On Volcengine Ark, pure video generation costs approximately 46 CNY per million tokens. A 15-second clip uses roughly 308,880 tokens, making the effective rate about $0.14 per second of output (per TechNode, March 5, 2026). Video-editing mode is about 39% cheaper.
Frequently asked questions about Seedance 2.0 specs
Are Seedance 2.0 specs the same across all access channels?▾
Yes. The Volcengine Ark API, seedance2-video.com hosted interface, and Doubao consumer app all run the same Seedance 2.0 model and deliver the same capability surface (1080p, 12 s, native audio, multi-reference). The differences are in pricing model, commercial-use rights, and sign-up requirements.
What is "multi-reference conditioning" in Seedance 2.0?▾
Multi-reference conditioning means you can provide up to three reference images simultaneously — for example, a character photo, a setting photo, and a style frame. The model uses all three as conditioning inputs during generation, enabling more consistent character-in-scene output.
Does Seedance 2.0 support 4K output?▾
No. Seedance 2.0 caps at 1080p native as of May 2026. 4K output is not documented in the Volcengine Ark specifications. Upscaling via a separate tool after generation is possible but not built in.
Can I generate videos longer than 12 seconds?▾
A single Seedance 2.0 generation is capped at 12 seconds. For longer content, the standard approach is to generate multiple clips and edit them together, which is how most production workflows use the model.
What is the frame rate of Seedance 2.0 output?▾
Seedance 2.0 outputs at 24 fps — standard cinematic frame rate — per Volcengine Ark documentation as of May 2026.
How do I access Seedance 2.0 specs in the API documentation?▾
