<h1 id="workflow-overview">Workflow Overview</h1>This workflow is designed to generate sound effects, ambient audio, and scene-based audio for videos using the Sony Woosh video-to-audio model inside ComfyUI.Since Sony Woosh only supports short video inputs of up to 8 seconds, this workflow automatically divides longer videos into smaller sections called segments. Each segment is processed individually and later merged into a complete audio track synchronized with the original video.The workflow supports both automatic and fully manual generation modes:<ul><li>Automatic Mode is designed for simplicity and speed. The workflow automatically analyzes the video and generates prompts for each segment with minimal user interaction.</li><li>Manual Mode gives full creative control over every segment, allowing you to define custom prompts, segment lengths, seeds, and audio behavior for dynamic or complex videos.</li></ul>The workflow also includes several utility systems to simplify the generation process:<ul><li>Automatic prompt generation using Qwen3.5 vision analysis</li><li>Frame visualization tools for precise segment timing</li><li>Audio preview nodes for testing segments before final rendering</li><li>Source audio mixing options</li><li>Optional dialog suppression using SAM3 masking</li></ul>This workflow is especially useful for:<ul><li>Silent videos</li><li>AI-generated videos</li><li>Videos requiring custom sound design</li><li>Videos with no usable original audio</li></ul>The final result is a fully rendered video containing the generated Sony Woosh audio, optionally mixed with the original source audio depending on the selected mode.<h3 id="comfyui-security-error-fix">COMFYUI SECURITY ERROR FIX</h3>If you hit a security level error while trying to install the Woosh custom node from ComfyUI manager:<ol><li>You need to temporarily change the security level in your config.ini file.</li></ol><ul><li>If you are using the portable version, the file is located at: ComfyUI/user/__manager/config.ini</li><li>Change the value to: security_level = weak</li></ul>IMPORTANT: Do NOT forget to restore it back to its original value, you should restore it afterward for safety reasons.<ol><li>Perform a hard restart of ComfyUI (completely stop it, then start it again).</li><li>Install the custom node using ComfyUI manager and double-check that it is the official one.
