控制柄平滑

Selects the method used to compute automatic Bézier handles (Automatic, Auto Clamped, Vector).

Yellow: *None*, Cyan: *Continuous Acceleration*. From left to right, four *Auto Clamped* keys, one *Vector*, and the rest are *Automatic*.

无

Only directly adjacent key values are considered when computing the handles. Vector handles are pointed directly at the adjacent keyframes.

This older method is very simple and predictable, but it can only produce truly smooth curves in the most trivial cases. Note the kinks in the yellow curve around the keys located between the extremes, and near the Vector handles.

持续加速

A system of equations is solved in order to avoid or minimize jumps in acceleration at every keyframe. Vector handles are integrated into the curves as smooth transitions to imaginary straight lines beyond the keyframe.

它产生开箱即用的更平滑的曲线，但必然意味着键值的任何变化都可能影响曲线的重要延伸的插值;尽管变化量随距离呈指数级衰减。任何带有自由、对齐或矢量手柄的键，以及带有 自动钳制 手柄的极端键都会阻止此更改传播。

The mode also tends to overshoot and oscillate more with fully Automatic handles in some cases (see the right end of the image above). So it is recommended to use Auto Clamped by default, and only switch to Automatic handles in places where this is desired behavior. That effect can also be reduced by adding in-between keys.

Tip

考虑到每种模式的共性与缺点，连续加速 应更适合有限的动画，动画使用少量插值关键帧，只需最少的手动润色。在高度润色的高键率动画的情况下，由于更广泛的修改传递造成的工作流中断，使用平滑可能会弊大于利。

插值

Mode for the Interpolation between the current and next keyframe.

插值

常量: 常量。

There is no interpolation at all. The curve holds the value of its last keyframe, giving a discrete (stairway) "curve". Usually only used during the initial "blocking" stage in pose-to-pose animation workflows.
线性: 线性。

This simple interpolation creates a straight segment, giving a non-continuous line. It can be useful when using only two keyframes and the Extrapolation extend mode, to easily get an infinite straight line (i.e. a linear curve).
贝塞尔: 贝塞尔。

The more powerful and useful interpolation, and the default one. It gives nicely smoothed curves, i.e. smooth animations!

Note

Remember that some F-Curves can only take discrete values, in which case they are always shown as if constant interpolated, whatever option you chose.

缓动（通过强度）

Different methods of easing interpolations for F-Curve segment. The "Robert Penner easing equations" (basically, equations which define some preset ways that one keyframe transitions to another) which reduce the amount of manual work (inserting and tweaking keyframes) to achieve certain common effects. For example, snappy movements.
