I used FUN VACE bf16 + Wan2.2 t2v fp16 to **Splice The Seams** (and nope, no 4-step acceleration LoRA).

* **Step 1:** Upload video 1 and video 2. They're only ever using **16 frames**.

* **Step 2:** Briefly describe the motion in your video.

* **Step 3:** Hit **Run**.

The final video you see is: **video 1 (16 frames) + VACE (17 frames) + video 2 (16 frames)**.

- I'll be posting more results on Twitter 👇.
