Prompt Studio Suite v3 - Reverse Image & MiniMax H3 Script Generator

⚡ UNIVERSAL WORKFLOW: Model-agnostic. Generates prompts optimized for Flux.1, SDXL, SD 1.5, Midjourney, and multi-shot video scripts for MiniMax H3.

◈ OVERVIEW

Prompt Studio Suite v3 is an automated reverse-engineering and multimodal prompt generation workbench for ComfyUI. Drop in any reference image to extract fine-tuned visual diffusion prompts or synthesize synchronized, production-ready video production scripts.

Works with any checkpoint (Flux, SDXL, SD 1.5, Midjourney) and video generators like MiniMax H3.

  Reads native image dimensions and injects dynamic composition parameters directly into the generation context.

• 🎨 Track A: Still Recreation Engine

  Deconstructs subjects, wardrobe textures, lighting direction, optical lens traits, and atmospheric depth into coherent, single-paragraph diffusion prompts.

• 🎬 Track B: MiniMax H3 Video Scripting

  Outputs structured 3-field production scripts:

  • integrated_multimodal_description (Numbered shots, camera moves, timestamps)

  • overall_soundscape (Synchronized diegetic audio cues)

  • non_diegetic_music (Atmospheric score pacing)

• 🎛️ Fast Switchboard Routing

  Powered by rgthree Fast Bypasser to toggle tracks instantly without rewiring graph connections.
