The EmptyCosmosLatentVideo 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, with configurable width, height, length, and batch size parameters.

Inputs

Parameter	Data Type	Required	Range	Description
width	INT	Yes	16 to MAX_RESOLUTION	The width of the latent video in pixels (default: 1280, must be divisible by 16)
height	INT	Yes	16 to MAX_RESOLUTION	The height of the latent video in pixels (default: 704, must be divisible by 16)
length	INT	Yes	1 to MAX_RESOLUTION	The number of frames in the latent video (default: 121)
batch_size	INT	No	1 to 4096	The number of latent videos to generate in a batch (default: 1)

Outputs

Output Name	Data Type	Description
samples	LATENT	The generated empty latent video tensor with zero values
