The OpenAIVideoSora2 node generates videos using OpenAI’s Sora models. It creates video content based on text prompts and optional input images, then returns the generated video output. The node supports different video durations and resolutions depending on the selected model.

Inputs

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

Constraints and Limitations:

• The “sora-2” model only supports “720x1280” and “1280x720” resolutions
• Only one input image is supported when using the image parameter
• Results are nondeterministic regardless of the seed value

Outputs
