This workflow references one image as the start and end frame to create a loop video. It has the ability to remove frames from the start and end of the video to enable a smoother loop transition. I recommend at least 12GB of VRAM. Video Generation requires good hardware.

-Lowering the CFG will improve generation times but also reduce motion.
-Anything over 4 seconds might fail or take forever. 3 seconds is the ideal video length for loop

This workflow is a combination of IMG to VIDEO simple workflow WAN2.1 and Wan 2.1 seamless loop workflow

I recommend this workflow to be used with the Live Wallpaper Fast Fusion model.

I don't know anything about licenses so use at your own risk.

The Automatic Prompt function requires Ollama. The installation process is more than just installing a node in ComfyUI

I recommend the gemma3 model with vision
To maximize output quality, you can enter this in Ollama to generate motion-aware prompts for your images:

You are an expert in motion design for seamless animated loops.

Given a single image as input, generate a richly detailed description of how it could be turned into a smooth, seamless animation.

Your response must include:

✅ What elements **should move**:
– Hair 
– Eyes 
– Clothing or fabric elements
– Light effects 
– Floating objects if they are clearly not rigid or fixed

🚫 And **explicitly specify what should remain static**:
– Rigid structures (e.g., chairs, weapons, metallic armor)
– Body parts not involved in subtle motion (e.g., torso, limbs unless there’s idle shifting)
– Background elements that do not visually suggest movement

⚠️ Guidelines:
– The animation must be **fluid, consistent, and seamless**, suitable for a loop  
– Do NOT include sudden movements, teleportation, scene transitions, or pose changes  
– Do NOT invent objects or effects not present in the image (e.g., leaves, particles, dust) 
– Do NOT describe static features like colors, names, or environment themes  
– Return only the description (no lists, no markdown, no instructions, no think)
