EmptyMochiLatentVideo - ComfyUI Built-in Node Documentation

Complete documentation for the EmptyMochiLatentVideo node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The EmptyMochiLatentVideo node creates an empty latent video tensor with specified dimensions. It generates a zero-filled latent representation that can be used as a starting point for video generation workflows. The node allows you to define the width, height, length, and batch size for the latent video tensor.

Inputs

Parameter	Description	Data Type	Required	Range
width	The width of the latent video in pixels (default: 848, must be divisible by 16)	INT	Yes	16 to MAX_RESOLUTION
height	The height of the latent video in pixels (default: 480, must be divisible by 16)	INT	Yes	16 to MAX_RESOLUTION
length	The number of frames in the latent video (default: 25, must satisfy that (length - 1) is divisible by 6)	INT	Yes	7 to MAX_RESOLUTION
batch_size	The number of latent videos to generate in a batch (default: 1)	INT	No	1 to 4096

Note: The actual latent dimensions are calculated as width/8 and height/8, and the temporal dimension is calculated as ((length - 1) // 6) + 1. The length parameter must satisfy that (length - 1) is divisible by 6, meaning valid values are 7, 13, 19, 25, etc.

Outputs

Output Name	Description	Data Type
samples	An empty latent video tensor with the specified dimensions, containing all zeros	LATENT
