EmptyCosmosLatentVideo - ComfyUI Built-in Node Documentation

EmptyCosmosLatentVideo creates an empty latent video tensor with the specified dimensions.

EmptyCosmosLatentVideo creates an empty latent video tensor with the 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	Description	Data Type	Required	Range
width	The width of the latent video in pixels (default: 1280, increments of 16)	INT	Yes	16 to MAX_RESOLUTION
height	The height of the latent video in pixels (default: 704, increments of 16)	INT	Yes	16 to MAX_RESOLUTION
length	The number of frames in the latent video (default: 121, increments of 8)	INT	Yes	1 to MAX_RESOLUTION
batch_size	The number of latent videos to generate in a batch (default: 1)	INT	No	1 to 4096

Note: The latent tensor is spatially downsampled by a factor of 8 in both height and width, and contains 16 channels. The number of latent temporal frames is calculated as ((length - 1) // 8) + 1.

Outputs

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