⚡ REFERENCE IMAGE → PRODUCTION-READY PROMPTSPrompt Studio Suite v3.2 is a reference-image analysis and multimodal prompt-generation workflow for ComfyUI. Load a reference image, optionally add creative direction, and generate a production-ready still-image prompt or structured MiniMax H3 video script.The still-image engine can tailor its prompt-writing strategy for Generic, FLUX, Krea 2, or SDXL.---### ◈ KEY CAPABILITIES🔍 Reference Image &amp; Aspect-Ratio AnalysisAnalyzes the reference image while automatically detecting its aspect ratio and feeding composition context into the prompt-generation engines.🎨 Still Prompt Studio — RECREATE / DIRECTGenerate detailed still-image prompts in two ways:- RECREATE: Leave Still Direction blank to reverse-engineer the reference as faithfully as possible.- DIRECT: Add Still Direction to modify the scene while retaining useful visual context from the reference.The still engine analyzes subjects, appearance, pose, wardrobe and materials, environment, composition, lighting, color, atmosphere, camera characteristics, optics, depth of field, and other visually relevant details.🎯 Target Model PromptingSet the Target Model to:- Generic — balanced, model-agnostic natural-language prompting- FLUX — coherent, literal descriptions emphasizing spatial relationships, materials, lighting, and camera perspective- Krea 2 — visually focused art direction emphasizing composition, mood, lighting, texture, color, and photographic/cinematic intent- SDXL — structured, keyword-aware prompting with explicit visual and technical detailThese presets change how the LLM writes the prompt rather than simply appending a model name.🎬 MiniMax H3 Video ScriptingThe independent video track creates structured multimodal production scripts containing:- <code>integrated_multimodal_description</code> — numbered shots, visual action, camera direction, movement, continuity, and timing- <code>overall_soundscape</code> — synchronized diegetic sound and environmental audio- <code>non_diegetic_music</code> — external score, mood, and musical pacing🎛️ Independent Still &amp; Video DirectionStill Direction and Video Direction are completely separate.You can recreate the reference image for the still track while giving entirely different direction to the video track, direct both independently, or leave either direction blank.🔀 Fast Track SwitchingPowered by <code>rgthree Fast Bypasser</code> so the still and video engines can be enabled or disabled without rewiring the workflow.🔒 Centralized API-Key InputOpenRouter credentials are entered through a dedicated API-key node.Never upload or distribute a workflow after entering your personal API key without first removing it.---### 📦 REQUIRED NODESInstall these extensions through ComfyUI Manager before running Prompt Studio:- <code>ComfyUI-Custom-Scripts</code> (pythongosssss)- <code>ComfyUI-KJNodes</code>- <code>rgthree-comfy</code>- <code>openrouter_node</code>An OpenRouter account/API key is required. API usage may incur charges depending on the models used and your OpenRouter account.---### 🚀 QUICK SETUP1. Load <code>prompt_studio_v3.json</code> into ComfyUI.2. Enter your OpenRouter API key in OpenRouter API Key.3. Load an image into Reference Image Input.4. For still-image prompting, enter <code>Generic</code>, <code>FLUX</code>, <code>Krea 2</code>, or <code>SDXL</code> in Target Model.5. Leave Still Direction blank for RECREATE, or add instructions for DIRECT mode.6. Add independent Video Direction if generating a MiniMax H3 video script.7. Enable the desired track under Studio Toggle Switches.8. Click Queue Prompt.---### ◈ LINKSGitHub Repository:<a target="_blank" rel="ugc" href="https://github.com/phibbyrizz/ComfyUI-Prompt-Studio">https://github.com/phibbyrizz/ComfyUI-Prompt-Studio</a>If you find Prompt Studio useful and want to support continued development:[Support Phibby](<a target="_blank" rel="ugc" href="https://ko-fi.com/phibby">https://ko-fi.com/phibby</a>)

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

Prompt Studio Suite v3.3<ul><li>Built-in AspectRatioDetector — no separate aspect-ratio custom node required.</li><li>Simplified aspect-ratio detection to IMAGE → aspect_ratio_str.</li><li>Aspect ratio is now display-only guidance for matching downstream image/video generation.</li><li>Aspect ratio is no longer injected into Still or Video prompt context.</li><li>Added Comfy Registry package metadata.</li><li>Public workflow ships with the OpenRouter API-key field blank.</li><li>Retains Target Model prompting for Generic, FLUX, Krea 2, and SDXL.</li></ul>Upgrading: If you previously installed the standalone <code>ComfyUI_AspectRatioDetector</code>, remove it from <code>custom_nodes</code> to prevent duplicate node registration.
