Tip

  • Pair with Seedream 5.0 Lite for the reference image first when targeting lifelike-face cohesion across multiple inputs.
  • Reference uploads that contain real human faces are rejected by the model. To use your own face, email support@empiriolabs.ai.

Uploaded media preprocessing

  • Video inputs are capped to 15 seconds for reference, edit, and extend workflows.
  • Uploaded video inputs are normalized to provider-compatible MP4 when needed.

Seedance 2.0 Pro

Multimodal video from text, images, audio, and video inputs. Native audio-video sync, strong motion stability, consistent character handling. Outputs up to 4K (3840x2160).

Tip

  • Pair with Seedream 5.0 Lite for the reference image first when targeting lifelike-face cohesion across multiple inputs.
  • Reference uploads that contain real human faces are rejected by the model. To use your own face, email support@empiriolabs.ai.

4K output

  • 4K outputs are native 10-bit H.265 (HEVC) for maximum quality, delivered in full on download and through the API. Browsers cannot decode 4K HEVC inline, so the playground plays a 1080p preview while Download gives the full 4K. Open 4K files in any HEVC-capable player or editor.

Uploaded media preprocessing

  • Video inputs are capped to 15 seconds for reference, edit, and extend workflows.
  • Uploaded video inputs are normalized to provider-compatible MP4 when needed.
