Blender动画关键帧比例缩放插件 Retime V1.0.3Retime可以同时选中多个关键帧，按照比例整体进行缩放It moves the items following the retimed items, so your animation stays tight and your markers stay useful.

You can edit while playing the animation, as it’s independent of playhead position.

It’s defined in frames, rather than scale percentage, so you work how you think.

It has options for customizing behavior just how you’d like, such as automatically adjusting total animation length.

支持的Blender版本：2.92, 2.93, 3.0, 3.1
