Clean Tracks

干净的足迹

The Clean Tracks command deletes neighboring Keys with the same value on a selected Track. Such Keys are redundant because no interpolation will take place between them and deleting the Keys will have no effect on the animation itself.

“清除轨道”命令将删除选定轨道上具有相同值的相邻键。这样的键是冗余的，因为它们之间不会发生插值，删除键将不会对动画本身产生影响。

At least three Keys must be involved in the removal process since the first and last Keys must remain.

由于第一个和最后一个钥匙必须保留，因此在移除过程中必须至少有三个钥匙。

Redundant Keys are created when an animation is imported and position, rotation or scale Keys are defined, even if they are set to 0 or another constant value. These Keys are not necessary in the Timeline view and also increase the file size unnecessarily - so get rid of them!

当导入动画并定义位置、旋转或缩放键时，即使它们被设置为0或其他常量值，也会创建冗余键。这些密钥在时间轴视图中是不必要的，并且不必要地增加了文件大小-所以摆脱他们！

Note that after the command is called up, the first key always contains the Interpolation step. Animated values will remain constant in the respective regions. This prevents over-shooting.

注意，在调用该命令之后，第一个键始终包含插值步骤。动画值将在各自的区域中保持不变。这样可以防止过度使用。
