LumaRay32KeyframeNode - ComfyUI Built-in Node Documentation

This node anchors a guide image to a specific position on the Luma Ray 3.2 output video timeline. Connect this node to the “keyframes” input of the Luma Ray 3.2 Keyframes to Video node, and chain several keyframes together by connecting the optional “keyframes” input.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	Guide image to place at the chosen moment of the output video.	IMAGE	Yes	-
`position`	How to place this image on the output video’s timeline.	COMBO	Yes	”Fraction of duration (0.0-1.0)" "Absolute time (seconds)“
`keyframes`	Optional earlier keyframes to chain with this one.	LUMA_RAY32_KEYFRAME	No	-

When “Fraction of duration (0.0-1.0)” is selected for the position parameter, you can specify a fraction value (default: 0.0, range: 0.0 to 1.0, step: 0.01) that determines where in the output video this image applies (0.0 = start, 1.0 = end). When “Absolute time (seconds)” is selected for the position parameter, you can specify a seconds value (default: 0.0, range: 0.0 to 10.0, step: 0.1) that determines the time in seconds from the start of the output video where this image applies.
