    Please check my video instructions first. Thanks! The new features are not supported in the latest version of ComfyUI-SeedVR2_VideoUpscaler. As I said in the video. You need to change the version to nightly(the latest dev version).

    @FaboroHacks You're right ! My bad.

    I did switch to nightly still cant run it extra args give me errors then the seevr2 node also gives me weird errors

    @cristianbimandvr147 I faced the same problem. In my case, there were two folders from SeedVR2 in my custom nodes folder, I don’t know why. But deleting the one without “comfyui” in its name fixed the problem. It looks like a conflict issue.

    I followed the tutorial and my first video upscaled with the stock fp16 so I decided to try the gguf and installed a few of them but for some reason they are giving me back the same picture or video after 25 and 400s respectively. I tried switching back to the OG models but now everything is the same, set to 2160. I am very confused and went back to follow your process several times to see where I went wrong.
