    WAN VACE Auto Joiner β€” Seamlessly Join Multiple FLF2V Clips


    πŸ“ SHORT DESCRIPTION (for preview)

    Turn your short WAN 2.1/2.2 FLF2V clips into one long, seamless video with one click! No more ugly cuts between clips.


    πŸ“ MAIN DESCRIPTION

    🎬 THE PROBLEM

    You've generated beautiful video clips using WAN 2.1 FLF2V or WAN 2.2 FLF2V β€” but they're all separate 81-frame clips. Manually joining them creates visible seams where the clips meet.

    ✨ THE SOLUTION

    WAN VACE Auto Joiner uses VACE to intelligently blend transitions between your clips. Just put your videos in a folder, set up the workflow, and click Queue once. The workflow automatically:

    - Processes each transition through WAN VACE
    - Maintains visual consistency between clips
    - Outputs one seamless video

    🎯 PERFECT FOR

    - Long-form video creation (combine 5, 10, 20+ clips)
    - Story sequences with multiple scenes
    - Music videos with flowing visuals
    - Any multi-clip FLF2V workflow

    ⚑ EFFICIENCY

    For N videos, VACE runs exactly N-1 times. No wasted computation!

    - 4 clips β†’ 3 VACE runs
    - 8 clips β†’ 7 VACE runs
    - 20 clips β†’ 19 VACE runs

    hey thsi seems to work perfectly at 640x1120, but not any other size, it always says all video must be the same size, even if they all are the same, other than that size?

    If anyone is having this problem, delete the constant nodes that connect both height and width and just connect them directly to the wan node on the right inputs in thegroup to the right
