This ComfyUI workflow turns a plain-text prompt into a fully produced video with synchronized dialogue, sound effects, and music using the HappyHorse 1.1 model. The HappyHorseTextToVideoApi node sends your prompt and settings to the HappyHorse service, which generates a single video file with the audio track baked in. The SaveVideo node then writes that returned video to disk at your chosen path, so you end up with one ready-to-share file.
Technically, the workflow is lean and focused: HappyHorseTextToVideoApi handles all generation remotely (visuals and audio together) and outputs a unified video object. There is no intermediate frame assembly or separate audio pipeline to manage in ComfyUI. This makes it ideal for rapid iteration on short episodic content, product spots, and cutscenes where timing between visuals and sound is critical but you want to avoid multi-node complexity. By structuring your prompt with clear scene descriptions, quoted dialogue, and simple sound/music cues, you can guide HappyHorse 1.1 to produce coherent, timed sequences that SaveVideo preserves as a single file.
