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). 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. Extensions are always 5 seconds long.

Inputs

Common 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. Default: "" (empty). This value is required and must not be empty.	STRING	Yes	–
`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)“
`prompt`	Text prompt for the new content. Default: "" (empty). 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 (18446744073709551615)

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
