LumaRay32ExtendVideoNode - ComfyUI Built-in Node Documentation - ComfyUI

Luma Ray 3.2 Extend Video continues a previous Luma Ray 3.2 video generation by creating a new 5-second segment either after the original clip (forward) or before it (backward). Connect the generation_id output from an earlier Luma Ray 3.2 node to use that clip as the starting frame (forward) or ending frame (backward) of the extension.

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. This value is required and must not be empty.	STRING	Yes	–
`direction`	Forward continues after the prior clip; backward is prepended before it. Selecting “Forward (continue after)” also adds the `loop` option.	COMBO	Yes	”Forward (continue after)" "Backward (lead-in before)“
`loop`	Loop the extended video seamlessly (forward extend only). Only available when `direction` is “Forward (continue after)”. Default: False.	BOOLEAN	No	True False
`prompt`	Text prompt for the new content. Must be between 1 and 6000 characters.	STRING	Yes	–
`resolution`	Output resolution for the extended video segment. Default: “720p”.	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
