    Video Interpolation and Upscaling to 4K with TensorRT for ComfyUI and RTX50 Series GPUs - v1.0
    NSFW

    Here is my tried and tested, and very FAST workflow for video interpolation and upscaling using ComfyUI.

    NOTE: This will only work for nVidia "Blackwell" 50xx series GPUs.

    Please consider supporting me on RiotModels to help me in continuing to make new LoRAs. Your reward is exclusive content of the Seven Sisters in the most naughty of animations.

    The flow is:

    • Load input video

    • First Interpolation (x2 Frames)

    • Second Interpolation (x2 Frames)

    • Upscale using TensorRT (loading from model)

    • Resize by Longer Side to 4K

    • Save output video

    Usage notes:

    If using Wan Video at native 16fps, using both interpolation nodes will get you to 64fps, good enough for 60fps approximation, but note that this will really stress your system RAM at the Upscale node if going full 4x on Upscaling. So for 60fps you really want to use only a 2x Upscaler and I recommend bypassing the second interpolation node and settling with 32fps if upscaling by 4x.

    For resizing to 4K, set "3840" for landscape videos and "2160" for portrait or square videos.

    Enjoy!

    It doesn't even open because it's just a list of nodes with data. Just why? And the TensorRT node sucks

    It's a ComfyUI workflow. You drag the JSON file onto a blank ComfyUI workflow. And what sucks about the Tensorrt node? I get much faster upscaling than with the standard upscale nodes.

    @Generation3dX I'm actually getting the same error. Blank workflow, drag it in, and all it does is say all nodes successfully installed, but the canvas is blank. Really wanted to try this, got a 5090 w/256gb RAM

    @The_Last_Goblin_King I just checked the download again. saved the zip file, unzipped the .json file to a separate directory outside the zip file and then dragged the .json file onto a blank workflow. No problems! Check that you have ComfyUI fully up to date, and also that you save the json file outside of the zip file first (don't try dragging it directly from inside the zip).

    @Generation3dX I got the same error, even worse. When I drag and drop it says missing nodes i click ok and it doesn't even download the new project on blank canvas, it stays on the old project page. I'm using the latest comfyui 0.36.0 5sept. I can't even download the missing nodes automatically

    I get an error when installing rife (I installed tensorrt upscaler, it works). Did you encounter any difficulties during installation? Do I need to make an interpolation model myself?

    I have been getting an error with tensorrt in a more integrated workflow with actual video generation, but for this workflow, which is completely separate from vidgen, it's been working just fine. Check you have the latest versions of all nodes - they should then download the most appropriate RIFE libs. If you still get errors, try deleting the RIFE files to force the node to download the latest version.

    The biggest issue with Tensorrt, is that the 2 nodes from the manager, are no longer updated sicne a long time. And honestely, the installation is a real nightmare.
    Installing from manager never work.
    Installing directelly by open cmd from the custom node folder, and git pull....also fail.
    The custom nodes are installed, but once you try to search the tensorrt nodes to add in your WF, they are not present, simply because the installation is totally bugged with this two nodes, and as they are no longer updated, there will never be a fix.
    I tried installing the upscaler tensorrt, it worked 1, failed 35 times.
    I tried installing the frame interpollation tensorrt node, failed 55 times....
    No comment, i gave up.
    I don't try to install tensorrt for your WF, but for my own WF. I'm just share my nightmare expenrience trying to install the two tensorrt nodes, upscaler and interpolation.
