Mode:

Edit Mode

Menu:

Key ‣ Transform

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

Move, Rotate, Scale

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

Extend

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.

팁

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

Copy/Paste

Reference

Menu:

Key ‣ Copy Keyframes, Key ‣ Paste Keyframes

단축키(hotkey):

Ctrl-C, Ctrl-V

Use Ctrl-C to copy selected keyframes and Ctrl-V to paste the previously copied keyframes. During the paste action, the Adjust Last Operation panel provides some options in how the paste is applied.

Offset

Duplicate

Reference

Shift-D

Duplicates the selected keyframes. You can reposition them by moving the mouse.

Delete

Reference

Menu:

Key ‣ Delete

단축키(hotkey):

X, Delete

Pressing X or Delete opens a pop-up menu from where you can delete the selected keyframes.

Handle Type

Reference

Menu:

Key ‣ Handle Type

단축키(hotkey):

V

Sets the handle type of the selected keyframes.

Interpolation Mode

Reference

Menu:

Key ‣ Interpolation Mode

단축키(hotkey):

T

Sets the interpolation mode between the selected keyframes.

Easing Type

Reference

Menu:

Key ‣ Easing Type

단축키(hotkey):

Ctrl-E

Sets the easing mode of the selected keyframes.

Density

Decimate

Reference

Menu:

Key ‣ Density ‣ Decimate (Ratio)

Menu:

Key ‣ Density ‣ Decimate (Allowed Change)

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

Mode

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

Ratio:

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

Error Margin:

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.

Sample Keyframes

Reference

Menu:

Key ‣ Density ‣ Sample Keyframes

단축키(hotkey):

Shift-Alt-O

Sampling a set of keyframes replaces interpolated values with a new keyframe for each frame.

F-Curve before sampling.

Clean Keyframes

Reference

Menu:

Key ‣ Density ‣ Clean Keyframes

단축키(hotkey):

X

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

팁

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).

Channels

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.

Blend

Reference

Menu:

Key ‣ Blend

단축키(hotkey):

Alt-D

Breakdown

Reference

Menu:

Key ‣ Blend ‣ Breakdown

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.

Factor

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.

Blend to Neighbor

Reference

Menu:

Key ‣ Blend ‣ Blend to Neighbor

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.

Blend

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.

Blend to Default Value

Reference

Menu:

Key ‣ Blend ‣ Blend to Neighbor

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.

Blend

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.

더 보기

The Reset to Default operator resets any property to its default value without the need of keyframing.

Ease

Reference

Menu:

Key ‣ Blend ‣ Ease

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.

Blend

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.

Smooth

Menu:

Key ‣ Smooth

단축키(hotkey):

Alt-S

Smooth (Legacy)

Reference

Menu:

Key ‣ Smooth ‣ Smooth (Legacy)

단축키(hotkey):

Alt-O

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.
