How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this ImpactSAM2VideoDetectorSEGS node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• SEGS (SEGS): ["5", 0]
