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.
