⚡ 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.

◈ KEY CAPABILITIES

• 🔍 Automated Optical & Aspect Detection

  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.

• 🔒 Clean & Decoupled Security

  Dedicated credential node with zero hardcoded API keys.
