NormalizeVideoLatentStart - ComfyUI Built-in Node Documentation

This node adjusts the first few frames of a video latent to make them look more like the frames that come after. It calculates the average and variation from a set of reference frames later in the video and applies those same characteristics to the starting frames. This helps create a smoother and more consistent visual transition at the beginning of a video.

Inputs

Parameter	Description	Data Type	Required	Range
`latent`	The video latent representation to process.	LATENT	Yes	-
`start_frame_count`	Number of latent frames to normalize, counted from the start (default: 4).	INT	Yes	1 to 16384 (max resolution)
`reference_frame_count`	Number of latent frames after the start frames to use as reference (default: 5).	INT	Yes	1 to 16384 (max resolution)

Note: The reference_frame_count is automatically limited to the number of frames available after the starting frames. If the video latent is only 1 frame long, no normalization is performed and the original latent is returned unchanged.

Outputs

Output Name	Description	Data Type
`latent`	The processed video latent with the starting frames normalized.	LATENT
