LumaVideoNode - ComfyUI Built-in Node Documentation - ComfyUI

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. Note: This node is marked as deprecated in the source code.

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.

Outputs
