LumaRay32ExtendVideoNode - ComfyUI Built-in Node Documentation

Luma Ray 3.2 Extend Video extends a previous Luma Ray 3.2 video generation by adding new content either after it (forward extension) or before it (backward extension). Connect the generation ID output from a prior Luma Ray 3.2 node to create a seamless 5-second extension of your video.

Inputs

Parameter	Description	Data Type	Required	Range
`source_generation_id`	Generation ID of the prior Ray 3.2 video to extend. Connect the generation_id output of another Luma Ray 3.2 node.	STRING	Yes	–
`direction`	Forward continues after the prior clip; backward is prepended before it. When “Forward (continue after)” is selected, you can optionally enable loop mode.	COMBO	Yes	”Forward (continue after)" "Backward (lead-in before)“
`loop`	Loop the extended video seamlessly (forward extend only).	BOOLEAN	No	True False
`prompt`	Text prompt for the new content.	STRING	Yes	–
`resolution`	Output resolution for the extended video segment.	COMBO	Yes	”540p" "720p" "1080p”
`seed`	Random seed for reproducible generation results.	INT	Yes	–

Note: The loop parameter is only available when direction is set to “Forward (continue after)”. When using “Backward (lead-in before)”, the loop option is not available. The prompt must be between 1 and 6000 characters. The source_generation_id is required and must be connected from a prior Luma Ray 3.2 node’s generation_id output.

Outputs

Output Name	Description	Data Type
`VIDEO`	The generated 5-second extended video segment.	VIDEO
`generation_id`	Unique identifier for this generation, which can be connected to another Luma Ray 3.2 Extend Video node for further extensions.	STRING
