This node creates a personal video asset for Seedance 2.0. It uploads your input video and registers it within a specified asset group. If you don't provide a group ID, it will guide you through a real-person verification process in your browser to create a new group first.

## Inputs

| Parameter  | Data Type | Required | Range | Description                                                                                                                                                                                                     |
| ---------- | --------- | -------- | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `video`    | VIDEO     | Yes      | -     | Video to register as a personal asset.                                                                                                                                                                          |
| `group_id` | STRING    | No       | -     | Reuse an existing Seedance asset group ID to skip repeated human verification for the same person. Leave empty to run real-person authentication in the browser and create a new group. (default: empty string) |
