EmptyLTXVLatentVideo - ComfyUI Built-in Node Documentation

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

The EmptyLTXVLatentVideo node creates an empty latent tensor for video processing. It generates a blank starting point with specified dimensions that can be used as input for video generation workflows. The node produces a zero-filled latent representation with the configured width, height, length, and batch size.

Inputs

Parameter	Description	Data Type	Required	Range
width	The width of the latent video tensor (default: 768, step: 32)	INT	Yes	64 to MAX_RESOLUTION
height	The height of the latent video tensor (default: 512, step: 32)	INT	Yes	64 to MAX_RESOLUTION
length	The number of frames in the latent video (default: 97, step: 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

Outputs

Output Name	Description	Data Type
samples	The generated empty latent tensor with zero values in the specified dimensions	LATENT
