Get Image Count 🎥🅥🅗🅢(GetImageCount)

The Get Image Count 🎥🅥🅗🅢 node, from a technical implementation perspective, receives a PyTorch Tensor as input, typically with a shape of [batch_size, height, width, channels].

The Get Image Count node is a utility tool for image sequence processing. Its core function is to receive a batch of images (of type IMAGE) and quickly calculate the total number of images contained within that batch. This node does not modify the image content; it only performs the counting operation and outputs the result as an integer (INT).

Node Functionality

From a technical implementation perspective, this node receives a PyTorch Tensor as input, typically with a shape of [batch_size, height, width, channels]. The node accesses the first dimension of the tensor (i.e., size(0)) to obtain the number of images in the batch. It supports the standard IMAGE data type in ComfyUI and can seamlessly process image sequences output by other image generation or loading nodes.

Usage Scenarios

In practical workflows, this node is often used in stages that require dynamic decision-making based on the number of images. For example, in a video frame processing pipeline, this node can first be used to obtain the total number of frames extracted from a video. This value can then be passed to a loop node to control the number of iterations for post-processing (such as upscaling, color grading) on each frame, thereby enabling automated batch operations.

Notes

This node only has requirements for the dimensions of the input data; the input must be a valid, correctly shaped IMAGE tensor. If the input is not a batch of images (e.g., a single image), it will still return 1.
