LumaRay32ExtendVideoNode - ComfyUI Built-in Node Documentation

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).

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

Common Inputs

Parameter	Description	Data Type	Required	Range
direction	Forward continues after the prior clip; backward is prepended before it. Forward uses the source clip as the starting frame; backward uses it as the ending frame. Selecting “Forward (continue after)” adds the loop option.	DYNAMIC_COMBO	Yes	”Forward (continue after)" "Backward (lead-in before)“
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	–
prompt	Text prompt for the new content. Must be between 1 and 6000 characters.	STRING	Yes	1 to 6000 characters
resolution	Output resolution for the extended video segment. Default: “720p”.	COMBO	Yes	”540p" "720p" "1080p”
seed	Seed to determine if node should re-run; results are nondeterministic regardless of seed. Default: 0.	INT	Yes	0 to 0xFFFFFFFFFFFFFFFF

Forward (continue after) Inputs

Parameter	Description	Data Type	Required	Range
loop	Loop the extended video seamlessly (forward extend only). Default: False.	BOOLEAN	No	True False

Backward (lead-in before) Inputs

This direction adds no additional parameters.

Note: Extensions are always 5 seconds. The loop parameter is only available when direction is “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
