LumaVideoNode - ComfyUI Built-in Node Documentation

Generates videos synchronously based on a text prompt and output settings. This node creates video content using text descriptions and various generation parameters, producing the final video output once the generation process is complete.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	Prompt for the video generation (default: empty string). Must be at least 3 characters long.	STRING	Yes	-
`model`	The video generation model to use.	COMBO	Yes	`"ray_1_6"` `"ray_2"`
`aspect_ratio`	The aspect ratio for the generated video (default: “16:9”).	COMBO	Yes	`"16:9"` `"9:16"` `"1:1"` `"4:3"` `"3:4"` `"21:9"` `"9:21"`
`resolution`	The output resolution for the video (default: “540p”). This parameter is ignored when using the `ray_1_6` model.	COMBO	Yes	`"540p"` `"720p"` `"1080p"`
`duration`	The duration of the generated video. This parameter is ignored when using the `ray_1_6` model.	COMBO	Yes	`"5s"` `"9s"`
`loop`	Whether the video should loop (default: False).	BOOLEAN	Yes	-
`seed`	Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0).	INT	Yes	0 to 18446744073709551615
`luma_concepts`	Optional Camera Concepts to dictate camera motion via the Luma Concepts node.	CUSTOM	No	-

Note: When using the ray_1_6 model, the duration and resolution parameters are automatically ignored and do not affect the generation.
