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.

Bake Sound to F-Curves

Reference

Menu

Key ‣ Bake Sound to F-Curves

The Bake Sound to F-Curves operator takes a sound file and uses its sound wave to create the animation data.

Lowest Frequency

Cutoff frequency of a high-pass filter that is applied to the audio data.

Highest Frequency

Cutoff frequency of a low-pass filter that is applied to the audio data.

Attack Time

Value for the hull curve calculation that tells how fast the hull curve can rise. The lower the value the steeper it can rise.

Release Time

Value for the hull curve calculation that tells how fast the hull curve can fall. The lower the value the steeper it can fall.

Threshold

Minimum amplitude value needed to influence the hull curve.

Accumulate

Only the positive differences of the hull curve amplitudes are summarized to produce the output.

Additive

The amplitudes of the hull curve are summarized. If Accumulate is enabled, both positive and negative differences are accumulated.

Square

Gives the output as a square curve. Negative values always result in -1, and positive ones in 1.

Square Threshold

All values lower than this threshold result in 0.

Jump to Keyframes

Offset

No Offset

Pastes the keyframes in the location they were copied from.

Frame Relative

Pastes the keyframe relative to the current frame based on the locations of the keyframes relative to the current frame when they were copied.

Frame Start

Pastes the keyframes with the first keyframe of the copied set placed at the current frame.

Frame End

Pastes the keyframes with the last keyframe of the copied set placed at the current frame.

Type

Mix

Integrates the pasted keyframes in with existing keyframes only overwriting keyframes that share a frame.

Overwrite All

Removes all previous keyframes and replaces them with the pasted keyframes.

Overwrite Range

Overwrite keys in pasted range.

Overwrite Entire Range

Overwrite keys in pasted range, using the range of all copied keys.

Flipped

Decimate

Reference

Menu

Key ‣ Decimate (Ratio)

Menu

Key ‣ 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.

Slider Operators

Breakdown

Reference

Menu

Key ‣ Slider Operators ‣ Breakdown

Moves the selected keyframes to an in between position relative to the adjacent keyframes. 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 ‣ Slider Operators ‣ 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. 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.

Clean Keyframes

Reference

Menu

Key ‣ Clean Keyframes

단축키(hotkey)

X

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

F-Curve before cleaning.

Clean Channels

Reference

Menu

Key ‣ Clean Channels

단축키(hotkey)

X

Acts like the Clean Keyframes tool but will also delete 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.

참고

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).

Smooth Keys

Reference

Menu

Key ‣ Smooth Keys

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.
