    I didn't bother pixel-perfecting the nodes or lining them up neatly—as long as it’s clear what goes where and why, the rest doesn't really matter. Wasn't aiming for aesthetic perfection, and honestly, didn't have the time either! =)). Recommended page file size: at least 128 GB. Generating 5 seconds of 1920 by 1088 at 48 fps on 5060ti 16 + 64 ram takes about 500 seconds, 490-530 seconds of 1920 by 1088 at 24 fps on 5060ti 16 + 64 ram takes about 290-320 seconds =)) For optimal performance, NVMe speeds of 3000 MB/s to 3500 MB/s + . The best choice in terms of speed and quality | 0.5 | 16:9 | 1920 x 1088 | 9 | 3 |, perhaps it is still possible to optimize the process and finalize it, but there is no free time yet, it is even better to wait for the optimizations of the model and the associated nodes =))

    v3.0 I2V MiniMax H3 + LTX 2.5

    The upscaler has been ported to LTX 2.5
    Certain settings have been changed and optimizations added to accelerate the overall process
    Toggles are divided into groups, and options to quickly change step settings for upscale have been added
    for optimal processing, tailored for smooth video or with a higher tendency toward dynamics
    Settings for working with Lora for 4 steps have been factored in, with descriptions added for this specific Lora
    An option to crop and fit images directly inside the workflow has been added "for the lazy", with the new Crop (OreX) cropping functionality, aspect ratio tests were conducted in various options, such as 34:9 and 9:34, and different combinations rounded up to 32 pixels; in all options, the result was good.
    An example of an alternative model that works well in Ref2VA mode is provided
    as well as a toggle between I2VA and Ref2VA.
    Ref2VA uses a lightweight model that also performs quite well in I2VA
    it was tested with up to 3 references (image + audio + video) and the model handled it quite well.
