This workflow uses Wan2.1 VACE to turn any input video into a seamless loop.It feeds the last 15 frames of the input video, a X-30 frame blank segment, and the first 15 frames into VACE to generate a transition.Finally, it removes the overlapping 30 frames (15 from the end and 15 from the start) and merges the result with the original video for output.<img
