WAN 2.2 i2v workflow for LONG videos - CLEAN + UPSCALING!

This is a clean and concise workflow for ComfyUI that allows you to generate longer videos by chaining together up to 4 separate clips.

This workflow is based on my clean 3+3+3 lightning workflow that can be found here: /model/2194801/simple-wan-22-i2v-60-fps-video-comfyui-workflow-6-step-lightning-with-3-ksamplers-and-upscale

You can use this workflow to generate a single WAN 2.2 video or you can have it chain up to 3 additional videos based on the final frame of the previous clip. In this way you can create longer videos, with distinct changes in action or framing without needing to generate the whole thing in one go. Simply fine tune the first clip with the others disabled until you are happy. Then don't change that clip and move on to clip 2. ComfyUI won't spend time regenerating the earlier clips each time you want to tune the next one!

Please consider tagging this as a resource you used if you generate anything with it and upload it here. I'd love to see what you're making with the tool!
