This ComfyUI workflow turns a single text prompt into a finished video clip using the Flux 3 model. The Flux3TextToVideoNode interprets natural language into a complete moving scene with coherent action, camera motion, and synchronized sound. It’s designed for quick turnarounds: you set the prompt, pick a duration between 5–20 seconds, choose an aspect ratio from 9:16 to 21:9, and the node generates a 720p, 24 fps result with built-in audio.

Technically, the pipeline is minimal and focused. Flux3TextToVideoNode handles end-to-end generation from text, returning the video content (and its audio track) at the requested length, frame rate, and aspect ratio. The SaveVideo node then writes the output to disk as a single playable file. With only two nodes, it’s easy to understand, fast to set up, and reliable for creating social-ready clips, ad mockups, and cinematic concept shots without extra reference images or complex settings.
