    V1.1 - Minor update to the workflow.

    Minor update to the workflow.

    Add last frame generate after video upscaled.

    This was supposed to be included in the workflow for the next update of Minimax H3 workflow, but I feel like some users would just upscale every single output right after generating it.

    小更新

    在影片upscale後加入自動生成last frame.

    本來應該加在Minimax H3下次更新的Workflow中

    但總覺得有用家會每生成一條就立即upscale

    Simple workflow for Low VRAM user. (Extreme FAST)

    This workflow isn't limited to MiniMax H3 users—those running Wan2.2 and LTX-Video 2.3 can use it exactly the same way.

    Just a quick heads-up: if your video has no audio, remember to disconnect the Audio link from the Load Video node, otherwise you'll get an error.

    Once again, what I'm sharing today is an ultra-simple workflow. It follows my usual style: simple, practical, completely spaghetti-free, and 100% Low VRAM friendly.

    I’ve covered the rest of the details directly inside the workflow, so I won't repeat them here.

    Low VRAM專用放大影片Workflow. (極快)

    不限於Minimax H3 用家, Wan 2.2 和LTX 2.3的用家同樣可用

    沒聲音的影片記得斷開Load Video 中Audio的連接, 不然會報錯

    今次分享的亦是超簡單Workflow。

    亦遵循我一貫作風, 簡單, 實際, 不會意粉化, Low VRAM能用

    其他詳細在workflow中有說明就不再重覆了
