    ComfyUI — I2V Wan Witchcraft - v1
    NSFW
    Preview 60623671

    Hello there and thanks for checking out this workflow!

    Purpose

    Built to provide an efficient and straightforward image-to-video pipeline, including ►INFO guides explaining various settings and modular sections to turn On/Off for quality of life and customization.

    Features

    • Installation and download guide for models and nodes

    • Florence 2 prompting assistance

    • Frame Interpolation

    • Upscaling

    Custom Nodes

    All of which can be installed through the ComfyUI-Manager

    Troubleshooting

    1. If nodes show up red (failing to load), check the 'Install Missing Custom Nodes' tab of the ComfyUI Manager for the missing node packs and install them.

    2. Please check if all custom node packs load properly after installing, i.e. no (IMPORT FAILED) messages next to any of them in the console upon ComfyUI startup.

    3. Always reload/drag'n'drop the original, downloaded workflow file into ComfyUI to reload an intact version of the workflow.

      → The last opened workflow that appears on startup shows a cached version of the workflow, "remembering" group nodes that failed due to missing nodes as failed, keeping them broken even after having everything installed correctly.

    Specific issues :

    • LatentClamp '>' not supported between instances of 'Tensor' and 'str'
      → Ensure you have the ComfyUI-Allor node pack installed and NOT the LatentClamp pack


    Thanks

    The workflow would not be possible as is without these custom node packs. If you want to support the custom node creators, give them a ⭐ on their github repos! Thank you!


    Feel free to ask questions, share improvements and suggestions in the comment section!
    Let me know if you encounter confusing points I can elaborate on in the next update!

    Even after manually installing all the listed custom nodes, I still have a few that show up red and aren't detected as missing in the Manager. These nodes are: workflowWan I2V Sampler, workflowUpscale Video, workflowFind Replace, workflowConditioning — AIO.
    I am still new to ComfyUI so I'm probably doing something wrong, any help with this would be appreciated.

    same, like the workflowwan 12v sampler

    Hey there, did you try dragging the original downloaded workflow file into Comfy again after installing all nodes and refreshing the page?

    Comfy displays the last opened workflow on restart, but does so with a cached version of it. So when you first load up the workflow with some nodes missing, it is basically caching broken group nodes as broken, so they won't be able to load even after installing the node packs.

    Could also be those nodes are only on the dev channel instead of the regular one. You can change channels in the manager and search for missing nodes again. Don't forget to change it back.

    @funscripter627 Thank you for pointing that out, but I managed not to use any of those in this workflow luckily 😄

    Unrelated to this workflow:
    I also figured out a way to make loops happen, within group nodes, using the Inspire Pack, which is way more common than the execution-inversion-demo.
    Only lazy switches are something no pack has in a "group-node-able" way unfortunately, to my knowledge at least :(
    Can't wait for subgraphs to be implemented, so I won't need to put anyone through unnecessarily troublesome installation processes anymore 🤞

    Are you using Comfy through Pinkoio by chance? If you are the way to fix this is to click on Comfy in the menu but don't start running it, then from the sidebar select "Download Mix," and then "Wan video"

    I finally managed to get it working by downgrading then upgrading the version of the cg-use-everywhere node pack. Maybe worth a try?

    In this specific case the issue is the broken cached version of the workflow, when you look closely you can see this among the errors:

    → workflowWan I2V Sampler
    which is missing the ">" symbol and should be:
    → workflow>Wan I2V Sampler

    That is what Comfy does when it can't put together a group node with missing parts. It just saves the group node wrong, resulting in this small change which breaks loading it no matter what.

    This specific detail is always solved by reloading the original file where all the group nodes are still labeled/referred to correctly within the .json file. It's just another #Comfy thing 😅

    @RedPinkRetro how do you do that, ive tried opening the original workflow and no change

    @Cyberai99 You can do that by drag and dropping the originally downloaded workflow file into Comfy

    If you still get the error, it means you are still missing custom node packs, which were either not installed or did not load correctly.

    RagingHorseMar 6, 2025

    Same the workflow looks broken to me. There is nothing "comfy" about comfyui.

    new to ComfyUI but had this struggle and I -think- the solution was that the workflow doesn't include Allor which is part of it? https://github.com/Nourepide/ComfyUI-Allor

    @gnivil498 Yes, exactly. The Allor Pack should be picked up on by the Comfy Manager's "Install Missing Custom Nodes" function, but is confused with the LatentClamp node pack due to a name conflict.

    That's why:
    Ensure you have the ComfyUI-Allor node pack installed and NOT the LatentClamp pack

    Workflow looks great but I'm getting the error "'>' not supported between instances of 'Tensor' and 'str'" on the conditioning node. Any ideas?

    Hey there, thank you kindly!

    Did you reload the original workflow file after installing all necessary node packs?

    Can you provide me with a screenshot of the setup that produced the error as well a .txt file containing the console log?

    @RedPinkRetro I probably should've mentioned I swapped the model to a gguf version in the everywhere node, but everything else is default. I'll still dm you if you don't mind. Thanks!

    I'm getting the same error, I have no idea what's causing it.

    bennyboy_77Mar 1, 2025· 1 reaction

    Similar error for me: "LatentClamp '>' not supported between instances of 'Tensor' and 'str'". Could it be an issue with the version of Python being used?

    EDIT: I've just noticed that my "Wan I2V Sampler" node looks completely different to the one in your example image for the workflow. I've got loads of extra fields showing including all the ones relating to Latent Clamp. I've only used the Comfy Manager to install the nodes from your workflow so I'd expect it ought to look the same as yours.

    Hey there, this issue was resolved quickly, however I did not post it on the page yet.
    The issue here is ComfyUI picking up a wrong node pack by mistake of the name "LatentClamp".
    Uninstall the "LatentClamp" node pack and ensure you have the ComfyUI-Allor node pack installed, then all should be fine!

    The Allor pack has a node called "LatentClamp", while there is a node pack itself (which came far later) called "LatentClamp", causing the confusion by misleading the "missing node pack detection" of the Comfy Manager unfortunately

    Thanks so much for taking the time to investigate. I'll give this a try and report back.

    @RedPinkRetro For some reason it wouldn't let me uninstall the LatentClamp node but I was able to disable it. After that, your workflow all worked without a hitch (well, it had defaulted to Sampler=null rather than "simple", but that was easy to fix!). Just playing with it now. I'm getting some pretty crazy results but I think I can tame it - haha. Thanks again.

    @bennyboy_77_uk Perfect! Glad it works now!

    I had some issues with uninstalling/disabling node packs myself. Uninstalling multiple ones in a row didn't work in a while and disabling/re-enabling caused some even weirder issues.
    Maybe just some residual junk my ComfyUI accumulated over all the updates.
    Basically I uninstall manually by deleting the folders in some cases 😅
