    Minimax H3 ref2va + fl2va Workflow

    • Simple toggle between ref2va and fl2va

    • Uses stock Minimax H3 sampler settings with Spectrum for a ~30-40% speed boost

      • I have yet to find a single other combination that doesn't have some kind of worse downside - The turbo LoRAs suck.

    • Motion Context video extension using save and load latents

      • How to use in workflow

      • Can lead to gamma shift after extending - may need to manually adjust brightness/contrast

    • FaceRefine for fixing distant garbled faces

      • required custom_nodes that aren't on the ComfyUI Manager included in archive

    • Simple postproduction settings

    • Postproduction looping tools for fl2va using the same first and last frame

      • clip still end or starting frames + audio

      • Smoothen out the loop with rife generated frames using Seamless Loop

    • Generation Preview

    • Batch or single video upscale using GIMM VFI+Tensorrt as toggle below the main workflow

      • throw your videos into any folder inside ComfyUI/input/... and toggle the batch upscale to get everything running

    No workflow will help, if your prompt doesn't follow the guidelines. I recommend looking through the following prompting guides if you have no idea about Minimax H3 prompt and then use other's or my prompts as help to get started.

    I added the full workflows, including prompt and resources I used in the example videos, to the workflow archive.

    If you have any questions just ask.

    This is mostly just a WF made for myself, uploaded it with some examples.

    MiniMaxH3NativeAudioLock node is missing. Comfy 0.37.0. All packs from resource links is installed. =(

    @PerfectLoop It's included in the workflow zipfile :). It's part of the facerefine and the author didn't include it in his github but it's hidden inside a folder of another git so I included it to make it easier. You can find it inside the custom_nodes folder here otherwise if you want to download it directly: https://github.com/Shrek3OnVH5/MiniMax-H3-NativeAudio-MusicVideo-Workflow/tree/master/custom_nodes

    Before i test this H3_Face_Refine_Auto_Select.json workflow i just want to know something: Will this work on my 5060 16gb GPU and 32 Gb system RAM?

    16GB VRAM is enough but you may have to drop down to a w4a8 model and nvfp4 or any smaller clip to not run out of RAM. I personally am using a 5080 and 96GB RAM. RAM is just as if not more important than VRAM since ComfyUI can do offloading very well.

    I also recommend increasing the size of your pagefile/swap so your system doesn't crash if it does overflow your RAM.
