WAN VACE Auto Joiner — Seamlessly Join Multiple FLF2V Clips

📝 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.

📝 MAIN DESCRIPTION

🎬 THE PROBLEM

You've generated beautiful video clips using WAN 2.1 FLF2V or WAN 2.2 FLF2V — 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 → 3 VACE runs
- 8 clips → 7 VACE runs
- 20 clips → 19 VACE runs
