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

V1.1 - Minor FixesMoved the concatenate for the prompt string to allow easier disable of Florence 2Adjusted some titles for clarityPinned the groups (because I kept moving them around, and I'm lazy and don't like cleaning up my own mistakes)Adjusted file naming, added a default "null" (0) seed as putting the seed in the name made for harder sorting (but left the original node in case someone likes it and wants to use it ... but prefix only on file names is a bummer ... maybe someone can tell me there is a postfix method out there)Clean up Raw Video output (I use this when I want to combine or adjust videos later without the interpolation frames)
