OpenAIVideoSora2 - ComfyUI Built-in Node Documentation

The OpenAIVideoSora2 node generates videos with OpenAI’s Sora models. It takes a text prompt along with an optional single reference image, sends the request to OpenAI, waits for generation to finish, and returns the resulting video. Supported durations and resolutions depend on the selected model. DEPRECATION NOTICE: OpenAI will stop serving the Sora v2 API in September 2026. This node will be removed from ComfyUI at that time.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The OpenAI Sora model to use for video generation (default: “sora-2”)	COMBO	Yes	”sora-2" "sora-2-pro”
`prompt`	Guiding text; may be empty if an input image is present (default: empty string)	STRING	Yes	-
`size`	The resolution of the generated video (default: “1280x720”)	COMBO	Yes	”720x1280" "1280x720" "1024x1792" "1792x1024”
`duration`	The duration of the generated video in seconds (default: 8)	COMBO	Yes	4 8 12
`image`	Optional input reference image used for video generation; only a single image is supported	IMAGE	No	-
`seed`	Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0)	INT	No	0 to 2147483647

Constraints and Limitations:

The “sora-2” model only supports the “720x1280” and “1280x720” sizes; selecting “1024x1792” or “1792x1024” with “sora-2” raises an error. The larger sizes are available only with “sora-2-pro”.
When an image is connected, it must contain exactly one image; connecting more than one image raises an error.
Results are nondeterministic regardless of the seed value.
The displayed price estimate depends on the selected model, size, and duration.
