<h1 id="qwen-vision-to-prompt-generator-or-universal-image-and-video-analysis">🎨 QWEN Vision-to-Prompt Generator | Universal Image &amp; Video Analysis</h1>Transform any image or video into ultra-detailed, model-optimized prompts using Qwen3-VL<hr /><h2 id="overview">📋 Overview</h2>This workflow leverages Qwen3-VL (Qwen Vision Language Model) to analyze images or videos and generate comprehensive, highly-detailed prompts optimized for your specific AI model. Whether you're working with FLUX, SDXL, WAN 2.1/2.2, or any other generative model, this workflow creates prompts that capture every nuance of your reference material.Perfect for:<ul><li>Creating detailed prompts from reference images</li><li>Analyzing video frames for consistent prompt generation</li><li>Reverse-engineering successful generations</li><li>Building comprehensive training datasets</li><li>Generating model-specific prompt optimizations</li></ul><hr /><h2 id="requirements">⚙️ Requirements</h2><h3 id="comfyui-custom-nodes">ComfyUI Custom Nodes</h3><ul><li><a target="_blank" rel="ugc" href="https://github.com/AIrjen/ComfyUI-QwenVL">ComfyUI-QwenVL</a> - Vision language model integration</li><li>pythongosssss Custom Scripts (ShowText node)</li><li>Core ComfyUI - LoadImage, LoadVideo, GetVideoComponents</li></ul><h3 id="model-options-(vram-considerations)">Model Options (VRAM Considerations)</h3>Recommended Models:<ul><li>Qwen3-VL-8B-Instruct (Default) - 8GB+ VRAM</li><li>Qwen2.5-VL-7B-Instruct - 6GB+ VRAM (Lower VRAM alternative)</li><li>Qwen2-VL-2B-Instruct - 4GB+ VRAM (Budget-friendly option)</li></ul>Quantization Settings:<ul><li>8-bit (Balanced) - Recommended for most users</li><li>4-bit - For lower VRAM systems (3-4GB)</li><li>Full Precision - Best quality but requires 12GB+ VRAM</li></ul><hr /><h2 id="how-to-use">🚀 How to Use</h2><h3 id="basic-workflow">Basic Workflow</h3><ol><li>Choose Your Input Type:<ul><li>For Image Analysis: Use the LoadImage node, BYPASS the LoadVideo and GetVideoComponents nodes</li><li>For Video Analysis: Use the LoadVideo node, BYPASS the LoadImage node</li></ul></li><li>Configure the QWEN Vision Node:<ul><li>Select your model size based on available VRAM</li><li>Choose quantization level (8-bit recommended)</li><li>Set attention mode (sdpa is default)</li></ul></li><li>Customize Your Prompt Request:<ul><li>CRITICAL: Update the custom question field to specify your target model</li><li>Examples:<ul><li><code>"Create an ultra detailed prompt optimized for FLUX"</code></li><li><code>"Create an ultra detailed prompt optimized for SDXL"</code></li><li><code>"Create an ultra detailed prompt optimized for WAN 2.1"</code></li><li><code>"Create an ultra detailed prompt optimized for ZImage"</code></li><li><code>"Create an ultra detailed prompt optimized for Pony Diffusion"</code></li></ul></li></ul></li><li>Generate &amp; Review:<ul><li>Run the workflow</li><li>View the generated prompt in the ShowText node</li><li>Copy the output for use in your generation workflows</li></ul></li></ol><hr /><h2 id="usage-tips">💡 Usage Tips</h2><h3 id="image-prompts">Image Prompts</h3><ul><li>Best for: Character references, scene composition, style analysis</li><li>Supports: PNG, JPG, WebP</li><li>Tip: Use high-resolution reference images for more detailed descriptions</li></ul><h3 id="video-prompts">Video Prompts</h3><ul><li>Best for: Motion analysis, sequential consistency, character movement</li><li>Supports: MP4, AVI, MOV, WebM</li><li>Tip: QWEN analyzes the entire video sequence for comprehensive prompts</li><li>Note: Longer videos may take more time to process</li></ul><h3 id="model-specific-optimization">Model-Specific Optimization</h3>Always specify your target model in the custom question!
