Mask Batch Split - Split mask batch into two parts

Node Purpose: Mask Batch Split splits a mask batch into two parts by a count, optionally taking from the start or the end. Handles edge cases and performs non-blocking slicing.

Inputs

Name	Port	Type	Default	Range	Description
mask	-	MASK	-	-	Input mask batch.
take_count	-	INT	8	1-1024	Number of frames in the taken part.
from_start	-	BOOLEAN	False	-	If True, take from the start; otherwise take from the end.

Outputs

Name	Type	Description
mask_1	MASK	First part of the split.
mask_2	MASK	Second part of the split.

Features

• Directional split: from_start=True takes the first take_count; otherwise the last take_count.
• Edge handling: when take_count >= batch_size, one output is full and the other is empty.
• Async slicing: uses worker threads to avoid blocking.

Typical Usage

• Separate mask prefixes from remaining segments.
• Keep last N masks while retaining the rest.

Notes & Tips

• Prints debug information on shapes and parameters, aiding graph debugging.
