    Wan 2.1 seamless loop workflow (i2v) - v1.2
    NSFW

    EDIT: tutorial video added to the examples of the 1.0 version, take a look.

    This is an i2v test workflow to generate seamless (or close) video using flow-two ComfyUI-WanStartEndFramesNative.

    It's not perfect. if you got better solution for seamless loop, i'm aware.

    details in the workflow.

    help: RuntimeError: output with shape [1, 14850, 5120] doesn't match the broadcast shape [2, 14850, 5120]

    it's pretty rare but sometime a random error can pop, can't find why, it's totally random.

    solution: increase or reduce the video length to the next or previous step and re-run.

    Description

    -adding sliders to control the output video fps and interpolation allowing a better speed and fluidity control. adding note on how to use.

    -correction of an issue, i've seen after the final interpolation, some frames miss between the last and the first frame, it's invisible with low interpolation but the gap increase with the final interpolation number and can create a jump, it's now good, the output video is perfect seamless.

    -the clean vram node was not connected on the 1.1, corrected.

    -be carreful, the "save output" button is now turned off by default in the final group to allow user to tune output settings without save every iterations, and the output video framerate is set to 60 fps.

    -minors improvements.
