    此节点由抖音博主：绘画小子 制作。

    增强视频动态，让首尾帧丝滑过渡！让首尾帧视频“动”得更自然、更干净！现在你可以用PainterFLF2V来制作顺滑的首尾帧视频，就像这样：

    Enhance video dynamics for smooth transitions between the first and last frames！Make first-last-frame videos move smoother & cleaner，Now you can use PainterFLF2V to create smooth first-and-last-frame videos, just like this:

    <table> <tr> <td><img src="image-6/wan2-2_00006.gif" alt="图1" width="684"></td> </tr> <tr> <td>motion_amplitude=1.3</td> </tr> </table>

    🎬 简介 | Intro

    PainterFLF2V 是对官方 WAN 首尾帧节点的“动态增强升级版”，你可以调节Motion Amplitude的数值，自定义视频的动态增强幅度。 通过反向结构斥力算法，一键消除慢动作与重影，同时保护颜色不失真。
    PainterFLF2V is the "dynamically enhanced upgraded version" of the official WAN first-last frame node. You can adjust the value of Motion Amplitude to customize the dynamic enhancement intensity of the video.
    Using inverse structural repulsion, it erases ghosting & sluggish motion while keeping colors intact.

    <table> <tr> <td><img src="image-6/1.gif" alt="图1" width="400"></td> <td><img src="image-6/2.gif" alt="图2" width="400"></td> </tr> <tr> <td>motion_amplitude=1.3</td> <td>motion_amplitude=1.3</td> </tr> </table>
