LTXVImgToVideoInplace - ComfyUI Built-in Node Documentation

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

The LTXVImgToVideoInplace node conditions a video latent representation by encoding an input image into its initial frames. It works by using a VAE to encode the image into the latent space and then blending it with the existing latent samples based on a specified strength. This allows an image to serve as a starting point or conditioning signal for video generation.

Inputs

Parameter	Description	Data Type	Required	Range
vae	The VAE model used to encode the input image into the latent space.	VAE	Yes	-
image	The input image to be encoded and used to condition the video latent.	IMAGE	Yes	-
latent	The target latent video representation to be modified.	LATENT	Yes	-
strength	Controls the blending strength of the encoded image into the latent. A value of 1.0 fully replaces the initial frames, while lower values blend them. (default: 1.0)	FLOAT	No	0.0 - 1.0
bypass	Bypass the conditioning. When enabled, the node returns the input latent unchanged. (default: False)	BOOLEAN	No	-

Note: The image will be automatically resized to match the spatial dimensions required by the vae for encoding, based on the latent input’s width and height.

Outputs

Output Name	Description	Data Type
latent	The modified latent video representation. It contains the updated samples and a noise_mask that applies the conditioning strength to the initial frames.	LATENT
