✨ WAN2.2 — StartEndFrames — Simple Workflow
A clean, all-in-one WAN image-to-video workflow built entirely with the UmeAiRT Toolkit for ComfyUI.
Only 12 nodes. No spaghetti wires. Just load your model, write your prompt, and hit generate.
⚠️ IMPORTANT — Nodes 2.0 Required
This workflow is built for the Nodes 2.0 (Vue) interface of ComfyUI. If you don't enable it, the workflow may have display problems.
How to activate Nodes 2.0:
Open ComfyUI
Go to Settings (⚙️ icon, bottom-left)
Find "Use Nodes V2 (Vue)" and toggle it ON
Refresh the page
Load the workflow
If you prefer the classic interface, check out my Legacy version of this workflow instead (link).
🎯 Features
Text-to-video generation
Automatic download of models in auto version
Built-in SeedVR2 upscaler — high-quality tiled upscaling (toggleable on/off) Slower than a classic upscaler, but significantly better quality
Full metadata embedding — your images are saved with all generation parameters, ready for online publishing and remixing
3 LoRA slots — with individual on/off toggles and strength control and you can connect as many other lora modules to each other for as many LoRA as you want.
📦 Custom Node Required
Only one custom node to install:
Install via ComfyUI Manager (search "UmeAiRT") or use the UmeAiRT Auto-Installer.
The Toolkit packages everything internally — upscaler, face detailer, metadata saver. No other custom nodes needed.

Got an error saying it "cannot access local variable 'clip_vision_output' where it is not associated with a value".
Maybe I'm missing something...?
Strange i dont use any clip vision for WAN2.2, you have updated comfyui?
UmeAiRT You're right! The problem was on my side. I was on Comfy's v0.3.47 instead of v0.3.48. Everything appears to be working now! Thank you for sharing the workflow!
For anyone else reading: I also had to update the custom node Lora Manager. They released an update yesterday and without it you'll be getting some weird errors.
Laura lightx2V -LoRA (i2v) does not work normally, you need to install text t2v
10/10 workflow
This workflow is amazing like always! :)
Gotta add the MagCache custom nodes to the requirements in the description tho 🙏
@UmeAiRT
Is there a way to set the weight/balance of the 1st or last frames? so that it doesn't just blending into the last frame in a few frames?
