# GeminiVideoOmniV2 - ComfyUI Built-in Node Documentation
> Google Gemini Omni (Video) generates a video with audio from a text prompt using Google's Gemini Omni Flash models.
Google Gemini Omni (Video) generates a video with audio from a text prompt using Google's Gemini Omni Flash models. You can optionally attach reference images and/or videos to guide the result or to edit existing footage. Describe the desired length (3-10 seconds) directly in the prompt.
## Inputs
### Common Inputs
| Parameter | Description | Data Type | Required | Range |
| --------- | -------------------------------------------------- | -------------- | -------- | ---------------------------------- |
| `model` | The Gemini video model used to generate the video. | DYNAMIC\_COMBO | Yes | "Omni Flash 1.1"
"Omni Flash" |
### Omni Flash 1.1 Inputs
| Parameter | Description | Data Type | Required | Range |
| -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------------------------------------------------------------------------------------------------------- |
| `prompt` | Describe the video to generate, or the edit to apply to an attached video. Specify the length directly in the prompt, e.g. "a 6-second clip" or, for the 'extend' task, "extend by 5 seconds"; the generated length may be 3-10 seconds and defaults to 10. The output has audio. (default: "") | STRING | Yes | - |
| `resolution` | Output resolution. (default: "720p") | COMBO | Yes | "360p"
"720p"
"1080p"
"4k" |
| `aspect_ratio` | Output aspect ratio: 16:9 (landscape) or 9:16 (portrait). The 'edit' and 'extend' tasks keep the aspect ratio of the input video instead. (default: "16:9") | COMBO | Yes | "16:9"
"9:16" |
| `task_type` | What to do with the prompt and the attached media. With 'auto' the model decides. 'text\_to\_video' generates from the prompt alone and rejects attached media. 'image\_to\_video' animates one image, or interpolates from a starting frame to an ending frame when two are attached. 'reference\_to\_video' treats the attached media as subject references. 'edit' rewrites exactly one attached video, and 'extend' appends new footage to it, so the output starts with the input video. (default: "auto") | COMBO | Yes | "auto"
"text\_to\_video"
"image\_to\_video"
"reference\_to\_video"
"edit"
"extend" |
| `seed` | Seed controls whether the node should re-run; results are non-deterministic regardless of seed. (default: 42) | INT | Yes | 0 to 2147483647 |
### Omni Flash Inputs
| Parameter | Description | Data Type | Required | Range |
| -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | --------------------------------------------------------------------------------------------- |
| `prompt` | Describe the video to generate, or the edit to apply to an attached video. Specify the length directly in the prompt, e.g. "a 6-second clip"; length may be 3-10 seconds. The output is 720p, 24 FPS, with audio. (default: "") | STRING | Yes | - |
| `aspect_ratio` | Output aspect ratio: 16:9 (landscape) or 9:16 (portrait). The 'edit' task keeps the aspect ratio of the input video instead. (default: "16:9") | COMBO | Yes | "16:9"
"9:16" |
| `task_type` | What to do with the prompt and the attached media. With 'auto' the model decides. 'text\_to\_video' generates from the prompt alone and rejects attached media. 'image\_to\_video' animates one image, or interpolates from a starting frame to an ending frame when two are attached. 'reference\_to\_video' treats the attached media as subject references. 'edit' rewrites exactly one attached video. (default: "auto") | COMBO | Yes | "auto"
"text\_to\_video"
"image\_to\_video"
"reference\_to\_video"
"edit" |
| `temperature` | Controls randomness. Lower is more focused/deterministic, higher is more varied. (default: 1.0) | FLOAT | Yes | 0.0 to 2.0 (step 0.01) |
| `top_p` | Nucleus sampling: sample from the smallest token set whose cumulative probability reaches top\_p. (default: 0.95) | FLOAT | Yes | 0.0 to 1.0 (step 0.01) |
| `seed` | Seed controls whether the node should re-run; results are non-deterministic regardless of seed. (default: 42) | INT | Yes | 0 to 2147483647 |
### Reference Inputs
| Parameter | Description | Data Type | Required | Range |
| --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | --------- | -------- | -------------- |
| `images` | Growable slot: connect up to 14 images (`image_1`...`image_14`). Optional reference image(s) to guide or animate the video. With the 'image\_to\_video' task the first one is the starting frame and an optional second one is the ending frame. | IMAGE | No | 0 to 14 images |
| `videos` | Growable slot: connect up to 3 videos (`video_1`...`video_3`). Optional reference video(s) to guide or edit. Each up to 10 seconds long. | VIDEO | No | 0 to 3 videos |
**Notes:**
* The `prompt` must not be empty; the node raises an error if it is.
* The `text_to_video` task generates from the prompt alone — attaching images or videos raises an error.
* The `image_to_video` task accepts images only (no videos) and requires exactly 1 or 2 images: the first is the starting frame and the optional second is the ending frame.
* The `edit` task (both models) and the `extend` task (Omni Flash 1.1 only) require exactly one input video and keep the aspect ratio of that input video, overriding `aspect_ratio`.
* At most 14 images and 3 videos can be attached, and each attached video must be 10 seconds or shorter.
* Omni Flash always outputs 720p 24 FPS video with audio; resolution selection is only available with Omni Flash 1.1.
* `temperature` and `top_p` controls are only available with the Omni Flash model; Omni Flash 1.1 uses fixed generation settings.
## Outputs
| Output Name | Description | Data Type |
| ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------ | --------- |
| `video` (first output) | The generated video with audio. For Omni Flash: 720p, 24 FPS. For Omni Flash 1.1: the resolution selected in the `resolution` input. | VIDEO |
| `text` (second output) | The text content generated by the model along with the video (may be empty). | STRING |
