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

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