Mask Repeat

Node Purpose: The Mask Repeat node is used to repeat the input mask (supports batch) for a specified number of times, and supports color inversion. It is suitable for scenarios where a single or a group of masks need to be expanded into a larger batch.

Inputs

Name	Port	Type	Default	Range	Description
mask	Required	MASK	-	-	Input mask batch.
count	-	INT	1	1-4096	Number of repetitions. The entire input Batch is treated as a unit for repetition.
invert	-	BOOLEAN	False	True/False	Whether to invert mask colors (swap black and white).

Outputs

Name	Type	Description
mask	MASK	The repeated (and optionally inverted) mask batch.

Features

• Batch Repeat:

  • If input Mask Batch is [A, B] and count is 2, the output will be [A, B, A, B].
  • The entire input Batch is treated as a whole for duplication.

• Invert Function:

  • When invert is True, the output mask colors are inverted (0 becomes 1, 1 becomes 0).
  • This operation is performed logically along with repetition.

Typical Usage

• Generate Long Sequence Masks: Expand a single looping mask to the number of frames required for video length.
• Invert and Expand: Simultaneously complete mask inversion and batch copying, simplifying the number of nodes in the workflow.
