    I'm having trouble finding the right words to explain in English: but to explain simply, you import a video and the workflow will automatically retrieve the last frame and the frame rate to generate a continuation of the video. Then the continuation is merged with the original.

    I'm having some problems running the workflow mostly on the upscaling part. always have error on low memory however the spec are GPU 5070 TI / 192 Memory ram xeon CPU 🄲at the moment in running the workflow with out scaling

    Your settings are too high or you are running too big of a model.

    Upscaling long videos requires a lot of VRAM

    @UmeAiRTĀ thank for the replay, I find out the problem. I was upscaling the video without limiting the framerate šŸ‘

    So, the "OG" output plays at the correct frame rate (16fps), but the EXT version is playing the new portion at double speed for some reason? I'm looking at the nodes and can't see where that is happening.

    Im having this exact problem

    @tyler273 playing around with it, on the Load Video node, manually setting 'force rate' to 16 seemed to do the trick.
