- Меню:
An F-Curve can be edited by transforming the locations of its keyframes.
- Переместить, Вращать, Масштабировать (move, rotate, scale)
Like other elements in Blender, keyframes can be moved, rotated, and scaled as described in Basic Transformations.
- Extend E
Lets you quickly move the selected keyframes that are on a certain side of the Playhead. This is handy if you need to, say, move all the keyframes after a certain time point to the right to make space for new ones.
To use this operator, first select some or all keyframes and place your mouse cursor to the left or right of the Playhead. Then, press E, move the mouse to move (only) the keyframes on that side of the Playhead, and press LMB to confirm (or RMB to cancel).
Совет
You can also change the Key Frame and Value properties in if you want to specify exact numbers.
While transforming keyframes, you can hold Shift to move them more slowly for better precision, or Ctrl to move them in coarse increments.

Clean Keyframes#
Ссылка
- Меню:
- Горячая клавиша:
X
Finds redundant keyframes among the selected ones and deletes them. A keyframe is seen as redundant if it has the same value as its neighbors – even if the curve segments around it aren’t flat.
Совет
This operator is likely to change the shape of the affected curves, so it’s best run after e.g. bulk keyframe insertion on all the bones of an armature (which creates useless keyframes on bones that haven’t moved) and before tweaking the curves by hand.
- Порог (threshold)
Value threshold. By increasing this, you can also delete keyframes that almost have the same value as their neighbors.
- Каналы (channels)
Cleans all the keyframes (even unselected ones) in the selected F-Curves. If a curve is left with only one keyframe, it’s deleted entirely.
Смешение (blend)#
Ссылка
- Меню:
- Горячая клавиша:
Alt-D
Adjusts the values of the selected keyframes by a certain percentage. Select a blending operator, move the mouse left or right to adjust the factor, and click LMB to confirm (or RMB to cancel).
Several blending operators work based on «neighboring keyframes.» This means that they divide the selected keyframes into contiguous groups, then reference the unselected keyframes immediately before and after each group.
Breakdown#
Ссылка
- Меню:
Sets the value of the selected keyframes to an interpolation of their neighbors.
- Коэффициент (factor)
At -1, the keyframes are set to the value of the left neighbor.
At 1, they’re set to the value of the right neighbor.
For other factors, they’re set to an interpolation between the two neighbor values, with 0 being right in the middle.
Blend to Neighbor#
Ссылка
- Меню:
Moves each selected keyframe towards the value of the left or right neighbor by a certain percentage.
- Смешение (blend)
When negative, each keyframe moves Blend percent to the value of the left neighbor.
When positive, they move to the right neighbor.
When zero, they keep their original values.
Blend to Default Value#
Ссылка
- Меню:
Moves the selected keyframes towards the property’s default value by a certain percentage.
- Коэффициент (factor)
How much to change the keyframes“ values, going from 0 (no change) to 1 (reset to the default value).
См.также
The Reset to Default operator resets any property to its default value without the need of keyframing.
Ослаблять (ease)#
Ссылка
- Меню:
Makes the selected keyframes follow an S-curve. While the slider is visible (so after activating the operator but before confirming with LMB), you can press Tab to toggle which of the following settings to edit:
- Curve Bend
A negative value gives more weight to the left side, while a positive value gives more weight to the right. A value of 0 results in a balanced curve.
- Острогранность (sharpness)
A low value results in an almost straight diagonal line, while a high value results in a steep rise/drop in the curve.
Blend Offset#
Ссылка
- Меню:
Moves the selected keyframes up or down – all by the same amount – until the first/last one matches the left/right neighbor.
- Offset Factor
At -1, the first selected key gets aligned to its left neighbor.
At 1, the last selected key gets aligned to its right neighbor.
At 0, nothing changes.
Blend to Ease#
Ссылка
- Меню:
Blends the selected keys to either an «ease in» or an «ease out» curve.
- Смешение (blend)
At -1, the keys will follow an «ease in» curve, with small value changes in the beginning and large changes towards the end.
At 1, the keys will follow an «ease out» curve, with large value changes in the beginning and small changes towards the end.
At 0, nothing changes.
Match Slope#
Ссылка
- Меню:
Blends the selected keys towards a straight line going through two keys just outside the current selection.
- Коэффициент (factor)
Negative values use the two keys to the left of the selection.
Positive values use the keys to the right.
At zero, nothing changes.
Push Pull#
Ссылка
- Меню:
Moves the selected keys towards, or away from, the straight line going through the first and last selected key.
- Коэффициент (factor)
At 0, the keys will lie on the straight line.
At 1, they keep their original values.
At 2, each key’s value will be twice as far from the straight line as before.
Shear Keys#
Ссылка
- Меню:
Shears the selected keyframes – that is, changes their value by an amount that increases as they get further away in time from a reference keyframe. By default, this reference keyframe is the leftmost selected one, but you can instead use the rightmost one by pressing D.
- Shear Factor
How much to shear. Negative values move keyframes downwards, while positive ones move them up.
- Направление (direction)
Whether to use the leftmost or the rightmost selected keyframe as a reference.
Scale Average#
Ссылка
- Меню:
Scales the selected keyframes vertically, using their average value as the pivot.
- Коэффициент (factor)
At 0, the keyframes will all have the average value.
At 1, they keep their original values.
At 2, each keyframe’s value will be twice as far from the average as before.
Scale from Neighbor#
Ссылка
- Меню:
Scales the selected keyframes vertically, using a keyframe just outside the selection as the pivot. By default, this is the neighbor to the left of the selection, but you can instead use the right one by pressing D.
- Коэффициент (factor)
Применяемый коэффициент масштабирования.
- Reference Key
Whether to use the left or right neighbor as the pivot.
Time Offset#
Ссылка
- Меню:
Shifts the values of the selected keyframes so that the resulting F-Curve appears to move in time. Works best with dense keyframes.
As the curve leaves the selected keyframes“ time range on one end, it wraps back in on the other, offset vertically so that the ends connect and there is no jump.
- Frame Offset (смещение кадра)
By how many frames to shift the F-Curve. The slider is limited to the range -10 … 10, but you can type larger numbers too.
Сглаживание (smooth)#
Ссылка
- Меню:
- Горячая клавиша:
Alt-S
Smooth (Gaussian)#
Ссылка
- Меню:
Smooths the selected keyframes using a Gaussian kernel. Click the menu item, move the mouse left or right to adjust the strength, and click LMB to confirm (or RMB to cancel).
- Коэффициент (factor)
How strongly the smoothing should be applied.
- Сигма
The shape of the gaussian distribution. Lower values mean a sharper curve, giving keys that are close to each other more weight. A high value behaves like a simple average filter.
- Filter Width
A wider filter looks at more keyframes, producing a smoother result. At a width of 1, the filter only looks at the keyframes to the immediate left and right for a weighted average.

Smooth (Legacy)#
Ссылка
- Меню:
- Горячая клавиша:
Alt-O
There is also an option to smooth the selected curves, but beware: its algorithm seems to be to halve the distance between each keyframe and the average linear value of the curve, which gives quite a strong smoothing! Note that the first and last keys seem to be never modified by this tool.
Butterworth Smooth#
Ссылка
- Меню:
Smooth the selected keyframes using a Butterworth filter. Click the menu item, move the mouse left or right to adjust the frequency, and click LMB to confirm (or RMB to cancel).
This filter is ideal for smoothing large amounts of data because it preserves the peaks of the animation. The downside is that it can introduce a ripple effect when the key values change rapidly.
- Frequency Cutoff
The lower the value, the smoother the curve. There is an implicit maximum at which the value no longer changes the curve, which is at half the sample rate. The sample rate in this case is the scene frame rate multiplied by the Samples per Frame of this operator.
- Filter order
Higher values mean the frequency cutoff is steeper.
- Samples per Frame
Before the filter is applied, the curve is resampled at this interval to avoid errors when there are uneven spaces between frames. If keys are on subframes, e.g. a 60fps file in a 30fps scene, increase this value to 2.
- Смешение (blend)
A value between 0 and 1 for blending between the original curve and the smoothed one.
- Blend In/Out
The number of frames at the start and end for which to blend between the original and smoothed curve. This can help reduce jumps in the animation at the selection border. At value 1, it only locks the first and last frames of the selection to their original values.
