Bulk operations for editing tracks and keyframes

This provides additional tools that can be used to precisely to offset or scale selected keyframes and tracks. For documentation on working with tracks and keyframes, please see the .
When the Keyframe Tools panel is active, a white bounding box is drawn around the selected keyframes for visual reference.
When ready, press Apply to process the selection.
This selects the type of operation to perform. Note that these changes are only applied to the current selection when the Apply button is pressed, and is undoable.
This is useful for making animation faster or slower. It multiplies the time of each keyframe by the value specified with some additional options.
Select the time you want to be the anchor point of the scale.
The amount to scale by. This number is multiplied with the keyframe time. For example, a value of 2 would be twice as slow (double the time), whereas a value of 0.5 would be twice as fast (half the time).
If enabled, the keyframe handles for Bezier curves are also scaled by the same amount. This is generally preferred to maintain the relative curves between keyframes.
If enabled, any selected events are also processed in the operation, or otherwise left unchanged.
This specifies the target or center value to scale by. A custom value can also be entered for further control.
This adds the specified amount to the keyframe values without changing the timing. Negative values can also be used to subtract value.
Applies smoothing to time and or values of selected keyframes. Smoothing is calculated as a an average of neighboring keyframes and may be applied multiple times for additional smoothing.
If enabled, the first and last keyframes remain unmodified.
If enabled, smoothing is applied to the keyframe values.
If enabled, smoothing is applied to the keyframe times, evening out the spacing between keyframes in time.
This slider determines the amount to smooth by and can be reduced for a more subtle effect.
Use this mode to apply randomization to selected track and keyframe times and/or values.
In the Time and Value +/- fields, enter the maximum amount of randomization offset, or set to 0 for no randomization.
Enable this option to randomize the start time of tracks only and maintain each track sections original lenght. Otherwise if this setting is off, randomizing time applies to both track start and end times.
Use this mode to simplify selected keyframes, reducing the number of keyframes overall to match the specified time interval, defined by a framerate, timestep, or duration.
If enabled, each interval step is snapped to the current grid measurement in time. Value snapping is not applied. Use Snap Time to ensure the new keyframes are aligned to the grid, otherwise if disabled the interval starts at the time of the first keyframe selected.
Resample is applied across the selected time range from the first to last keyframe in each channel keys are selected. The original keyframes selected are removed or replaced by new ones at the specified time interval. Any unselected keyframes remain unchanged.
This simplifies a curve by removing all keyframes except the maximal peaks and troughs. This is determined by calculating the direction the value is trending from one keyframe to the next, only keeping keyframes where the value direction reverses.
To open and close the Keyframe Tools panel, use the toggle button in the lower right corner of the mini inspector At least 1 keyframe or track must be selected.
To cancel without making any changes or when you are done using the tools, press the Keyframe Tools icon to close the panel.
Use this mode to add time defined in seconds. Negative values can also be used to shift keyframes and tracks earlier in time. Note that this changes the keyframe times directly and is unrelated to the value on channels and behaviors.
Sometimes bulk operations can cause keyframes to go out of the time range. If this happens the Timeflow may be adjusted as needed.
This mode is used to scale the values of keyframes, while leaving their timing unchanged. Typically this is used with the to increase or decrease the intensity or range of an animation.
To cancel or close the Keyframe Tools panel, simply click the icon
An alternate method to resample an entire channel curve is to use from the channel context menu.
After curve reduction, change the channel interpolation to for smooth curves.
