The LTXVConcatAVLatent node combines a video latent representation and an audio latent representation into a single, concatenated latent output. It merges the samples tensors from both inputs and, if present, their noise_mask tensors as well, preparing them for further processing in a video generation pipeline.

Inputs

Parameter	Data Type	Required	Range	Description
video_latent	LATENT	Yes		The latent representation of the video data.
audio_latent	LATENT	Yes		The latent representation of the audio data.

Note: The samples tensors from the video_latent and audio_latent inputs are concatenated. If either input contains a noise_mask, it will be used; if one is missing, a mask of ones (same shape as the corresponding samples) is created for it. The resulting masks are then also concatenated.

Outputs

Output Name	Data Type	Description
latent	LATENT	A single latent dictionary containing the concatenated samples and, if applicable, the concatenated noise_mask from the video and audio inputs.
