Recently integrated into Kijai&#039;s Wan Video extension for ComfyUI, this model allows for some incredible results if tweaked correctly. I&#039;m moving beyond the basic official examples to share a Fully Automated ComfyUI Workflow I built. By using math logic and loop nodes, this workflow automatically calculates how many extensions are needed based on your audio length, allowing you to generate infinite videos without manual labor. \ud83d\udd25 What you&#039;ll learn in this tutorial: The Model: How to set up Long Cat Video Avatar (BF16 vs FP8). The Workflow Evolution: Moving from Kijai&#039;s manual extension method to a fully automated loop system. Automation Logic: Using Math Expressions to calculate total frames and loop counts based on audio duration. Optimization Tips: Tuning Audio Scale (Recommended: 1.5) for better lip-sync without artifacts. Using Prompts (e.g., &quot;eating grapes&quot;) to add natural movement and reduce stiffness. Technical Details: Handling Overlap frames (13 frames), FPS settings, and Audio Stride. #runninghub #ComfyUI #AIAvatar #LongCatVideoAvatar #WanVideo #TextToVideo #AudioToVideo #StableDiffusionWorkflow
