Luma Text to Video - ComfyUI Built-in Node Documentation

Generates videos synchronously based on a text prompt and output settings.

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. Luma removes the endpoints this node calls on October 24, 2026, so use the Luma Ray 3.2 nodes instead.
