Get Mask Count 🎥🅥🅗🅢(GetMaskCount)

From a technical implementation perspective, the Get Mask Count 🎥🅥🅗🅢 node receives a MASK type input in PyTorch tensor format.

The Get Mask Count node is a utility tool for analyzing mask data. Its core function is to calculate the number of masks contained within the input mask tensor and output the result as an integer. This node is simple to operate and can quickly provide crucial quantity information for subsequent processing steps.

Node Functionality

From a technical implementation perspective, the node receives a MASK type input in PyTorch tensor format. Its core mechanism involves calling the mask.size(0) method, which returns the size of the tensor along its first dimension, typically corresponding to the number of masks in a batch. The node does not modify the mask content; it only performs a read operation on the dimension size.

Usage Scenarios

In video processing workflows, when using multiple mask sequences for compositing or effect application, you can use this node to dynamically obtain the total number of currently loaded mask frames. For example, when deciding loop counts or conditional branches based on the number of masks, connecting this node's output to a conditional judgment node enables automated control of the process.

Notes

This node can only process MASK type inputs and is ineffective for other data types. Its output result depends entirely on the shape of the input tensor. If the input tensor format is incorrect or empty, the expected count value may not be obtained.
