关键帧 ‣ 变换

An F-Curve can be edited by transforming the locations of the keyframes.

移动，旋转，缩放

Like other elements in Blender, keyframes can be moved, rotated, or scaled as described in Basic Transformations.

扩选

Moves keyframes relative to the current frame. If the mouse is to the left of the Playhead, this operator only affects the selected keyframes that are to the left of the Playhead. On the contrary, if the mouse is to the right of the Playhead, this operator only affects the selected keyframes that are to the right of the Playhead.

Tip

For precise control of the keyframe position and value, you can set values in the Active Keyframe of the Sidebar region.

The Decimate tool simplifies an F-Curve by removing keyframes that influence the curve shape the least.

模式

Controls which method is used pick the number of keyframes to use.

比率:

Deletes a defined percentage of keyframes, the amount of keyframes to delete is define by the Remove property.

边际误差:

Deletes keyframes which only allowing the F-Curve to change by a defined amount. The amount of change is controlled by the Max Error Margin which controls how much the new decimated curve is allowed to deviate from the original.

Clean Keyframes resets the keyframe tangents on selected keyframes to their auto-clamped shape, if they have been modified.

Tip

The modified curve left after the Clean tool is run is not the same as the original, so this tool is better used before doing custom editing of F-Curves and after initial keyframe insertion, to get rid of any unwanted keyframes inserted while doing mass keyframe insertion (by selecting all bones and pressing I for instance).

通道

Deletes the channel itself if it is only left with a single keyframe containing the default property value and it's not being used by any generative F-Curve modifiers or drivers.

间断

Moves the selected keyframes to an in between position relative to the adjacent keyframes. To use this operator, drag the mouse left or right to adjust the operator's Factor property.

系数

The amount to favor either the left or the right key. Values less than 0.5 favor the left keyframe, values greater than 0.5 favor the right keyframe, a value of 0.5 results in no change.

混合至邻帧

参考

菜单:

关键帧 ‣ 混合 ‣ 混合至邻帧

Transitions the current keyframe with the neighboring keyframes in the timeline. In order for this operator to work, there must be a keyframe before and after the current frame. To use this operator, drag the mouse left or right to adjust the operator's Blend property.

混合

The amount to favor either the left or the right key. Values less than 0.5 favor the left keyframe, values greater than 0.5 favor the right keyframe, a value of 0.5 results in no change.

混合到默认值

参考

菜单:

关键帧 ‣ 混合 ‣ 混合至邻帧

Transitions the current keyframe towards the property's default value. To use this operator, drag the mouse left or right to adjust the operator's Blend property.

混合

The amount to favor either the current key or the default value. A value of 0 represents the current key, a value of 1 represents the default value.

Aligns selected keyframes to follow an exponential path between the first and last keyframes. To use this operator, drag the mouse left or right to adjust the operator's Blend property.

混合

Changes the concavity of the curve. Values less than 0.5 cause keyframes to concave up, values greater than 0.5 cause keyframes to concave down, a value of 0.5 results in a straight line.

There is also an option to smooth the selected curves, but beware: its algorithm seems to be to divide by two the distance between each keyframe and the average linear value of the curve, without any setting, which gives quite a strong smoothing! Note that the first and last keys seem to be never modified by this tool.
