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	Data Type	Required	Range	Description
width	INT	Yes	64 to MAX_RESOLUTION	The width of the latent video tensor (default: 768, step: 32)
height	INT	Yes	64 to MAX_RESOLUTION	The height of the latent video tensor (default: 512, step: 32)
length	INT	Yes	1 to MAX_RESOLUTION	The number of frames in the latent video (default: 97, step: 8)
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 tensor with zero values in the specified dimensions
