This workflow is my take on organizing and building an I2V model running against a "smaller" graphics card (specifically 12 GB). I use Q5 GGUF models, though I have also tested against smaller Q4 and Q3 - each having a slight decrease to prompt adherence and quality, but still usable. This includes using the lightspeed lora and notes on where all models / loras can be downloaded from.I suggest if you have limited RAM or VRAM, to run ComfyUI with the parameter: --cache-noneWhile this will mean multiple batches against the same video will be slower, you get a much more consistent overall generation speed of your videos (3-4 minutes for 5-6 seconds on moderate home PC configurations).This also includes using Florence2 (LLM) for image detection and auto-prompt assistance. You only need to add your action to the manual prompt (if desired).There are a lot of nodes I have seen in various workflows ... but in Wan 2.2 I2V, at least, they tend to have no effect and only increase overhead.I run my videos typically in 480p @ 480 x 832, and this workflow then upscales by 2x to 960 x 1664.<h3 id="custom-nodes-used:">Custom Nodes Used:</h3>ComfyUI-GGUF (<a target="_blank" rel="ugc" href="https://github.com/city96/ComfyUI-GGUF">https://github.com/city96/ComfyUI-GGUF</a>)rgthree-comfy (<a target="_blank" rel="ugc" href="https://github.com/rgthree/rgthree-comfy">https://github.com/rgthree/rgthree-comfy</a>)ComfyUI-KJNodes (<a target="_blank" rel="ugc" href="https://github.com/kijai/ComfyUI-KJNodes">https://github.com/kijai/ComfyUI-KJNodes</a>)ComfyUI-Florence2 (<a target="_blank" rel="ugc" href="https://github.com/kijai/ComfyUI-Florence2">https://github.com/kijai/ComfyUI-Florence2</a>)ComfyUI-VideoHelperSuite (<a target="_blank" rel="ugc" href="https://github.com/Kosinkadink/ComfyUI-VideoHelperSuite">https://github.com/Kosinkadink/ComfyUI-VideoHelperSuite</a>)WAS Node Suite (<a target="_blank" rel="ugc" href="https://github.com/WASasquatch/was-node-suite-comfyui">https://github.com/WASasquatch/was-node-suite-comfyui</a>)

Wan 2.2 GGUF Workflow I2V with Upscale

Version 1.2 Notes:Cleaned up node layouts:<ul><li>General cleanliness</li><li>Organized prompts and settings (frame, width, height) to one section</li></ul>Minor changes to custom nodes<ul><li>Added new (improved) node to show final prompt (LLM + Manual, if you leave the LLM enabled)</li></ul>
