GeminiVideoOmni - ComfyUI Built-in Node Documentation - ComfyUI

Generate a video with audio from a text prompt using Google’s Gemini Omni Flash model. Optionally provide reference images and/or videos to guide or edit the result. Describe the desired length (3-10s) and aspect ratio (16:9 or 9:16) directly in the prompt.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The Gemini video model used to generate the video.	COMBO	Yes	”Omni Flash”
`seed`	Seed controls whether the node should re-run; results are non-deterministic regardless of seed (default: 42).	INT	Yes	0 to 2147483647
`prompt`	The text prompt describing the video to generate. Must be at least one non-whitespace character after stripping leading/trailing whitespace.	STRING	Yes	Minimum 1 character after stripping whitespace
`images`	Optional reference images to guide the video generation. Maximum of 14 images total.	IMAGE	No	Multiple images allowed (max 14)
`videos`	Optional reference videos to guide or edit the video generation. Maximum of 3 videos, each up to 10 seconds.	VIDEO	No	Multiple videos allowed (max 3, each max 10s)
`temperature`	Controls randomness in generation (default: 1.0).	FLOAT	No	0.0 to 2.0
`top_p`	Nucleus sampling parameter (default: 0.95).	FLOAT	No	0.0 to 1.0

Notes:

If an image input contains multiple frames, each frame counts toward the maximum of 14 images.
When images or videos are provided, the combined encoded media size must stay under about 90 MB; otherwise the node raises an error.

Outputs

Output Name	Description	Data Type
`VIDEO`	The generated video with audio from the Gemini model.	VIDEO
`STRING`	Any text response from the model, such as reasoning or explanations.	STRING
