Mask Batch to List - Split mask batch into single-frame list

Node Purpose: Mask Batch to List converts a multi-frame mask batch into a Python list where each element is a 1-frame batch (B=1). Preserves order and tensor properties.

Inputs

Name	Port	Type	Default	Range	Description
mask_batch	-	MASK	-	-	Input mask batch (B×H×W).

Outputs

Name	Type	Description
mask_list	MASK_LIST	List of single-frame mask batches, in original order.

Features

• Deterministic splitting: slices by index and keeps per-frame tensors as B=1 batches.
• Empty handling: returns an empty list when input is None or has B=0.

Typical Usage

• Convert a mask sequence to a list for nodes that operate per-frame.

Notes & Tips

• Each list item is shaped as a batch (1×H×W).
