Editing
Transform
Pregled
- Režim
Edit Mode
- Meni
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.
Савет
For precise control of the keyframe position and value, you can set values in the Active Keyframe of the Sidebar region.

Shift-Ctrl-M
Opens a pop-up allowing you to add modifiers to the active F-Curve. Settings for the modifier can be found in the tab.
Bake Sound to F-Curves
Pregled
- Meni
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

Copy/Paste
Pregled
- Meni
,

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
- 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
Paste keyframes from mirrored bones if they exist.
Duplicate

Decimate

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

The Reset to Default operator resets any property to its default value without the need of keyframing.
Clean Keyframes
Pregled
- Meni
- Shortcut
X
Clean Keyframes resets the keyframe tangents on selected keyframes to their auto-clamped shape, if they have been modified.

Clean Channels
Pregled
- Meni
- Shortcut
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.
Белешка
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
Pregled
- Meni
- Shortcut
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.

Shift-Alt-O
