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 <a target="_blank" rel="ugc" href="https://civarchive.com/models/1309369/img-to-video-simple-workflow-wan21-or-gguf-or-lora-or-upscale-or-teacache?modelVersionId=1803449">IMG to VIDEO simple workflow WAN2.1</a> and <a target="_blank" rel="ugc" href="https://civarchive.com/models/1426572/wan-21-seamless-loop-workflow-i2v">Wan 2.1 seamless loop workflow</a> I recommend this workflow to be used with the <a target="_blank" rel="ugc" href="https://civarchive.com/models/1655054?modelVersionId=1873761">Live Wallpaper Fast Fusion</a> model.

The installation process is more than just installing a node in ComfyUII recommend the gemma3 model with vision <img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/1e2705ed-5fb9-40c1-b4e5-16af082f3f32/width=525/1e2705ed-5fb9-40c1-b4e5-16af082f3f32.jpeg" />To maximize output quality, you can enter this in Ollama to generate motion-aware prompts for your images:<pre><code>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)</code></pre>---------- 📂Files : I recommend this workflow to be used with the <a target="_blank" rel="ugc" href="https://civarchive.com/models/1655054?modelVersionId=1873761">Live Wallpaper Fast Fusion</a> model.
