Deletes the whole channel from the current action (i.e. unlink the underlying F-Curve data-block from this action data-block).
The X shortcut is area-dependent: if you use it in the left list part, it will delete the selected channels, whereas if you use it in the main area, it will delete the selected keyframes.
Un/Groups the selected channels into a collection that can be renamed by double clicking on the group name. For example, this helps to group channels that relate a part of an armature to keep the editor more organized.
Toggle/Enable/Disable Channel Settings
Shift-W, Shift-Ctrl-W, Alt-W
Enable/disable a channel’s setting (selected in the menu that pops up).
- Protect, Mute
Toggle Channel Editability
Locks or unlocks a channel for editing.
Change the extrapolation between selected keyframes.
Extrapolation defines the behavior of a curve before the first and after the last keyframes.
There are two basic extrapolation modes:
The default one, curves before their first keyframe and after their last one have a constant value (the one of these first and last keyframes).
Curves ends are straight lines (linear), as defined by the slope of their first and last keyframes.
Additional extrapolation methods (e.g. the Cycles modifier) are located in the F-Curve Modifiers.
Add F-Curve Modifier
Opens a pop-up allowing you to add modifiers to the active F-Curve. Settings for the modifier can be found in the tab.
- Hide Selected Curves H
Hides the selected curves.
- Hide Unselected Shift-H
Show only the selected curve (and hide everything else).
- Reveal Curves Alt-H
Show all previous hidden curves.
Expands or collapses selected channels.
This allows you to move selected channels up/down PageUp, PageDown, or directly to the top/bottom Shift-PageUp, Shift-PageDown.
Revive Disabled F-Curves
Clears ”disabled” tag from all F-Curves to get broken F-Curves working again.
Frame Selected Channels
Reset viewable area to show the selected channels. To frame the channel that is under the mouse cursor, use Alt-MMB.
- Include Handles
Include handles of keyframes when calculating extents.
- Use Preview Range
Ignore frames outside of the preview range.
Keys to Samples
This operator replaces an F-Curve with a set of sampled points at each full frame. It is a destructive process that removes the ability to edit the curve. The main use for this is to reduce the file size with large datasets. Samples are only 1/5th the size per key. The sampled points interpolate linearly on subframes.
Samples to Keys
This operator replaces a sampled F-Curve with keyframes, adding the ability to edit it. It will not recreate the curve as it was before, instead it will place 1 key at every frame.
Sound to Samples
The Sound to Samples operator takes a sound file and uses its sound wave to create the animation data. By default this data will not be editable, use Samples to Keys to get editable keyframes.
- 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.
Minimum amplitude value needed to influence the hull curve.
Only the positive differences of the hull curve amplitudes are summarized to produce the output.
The amplitudes of the hull curve are summarized. If Accumulate is enabled, both positive and negative differences are accumulated.
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.
The Bake Channels operator creates new keyframes on the F-Curves of channels that are selected in the channel box.
The range that will be baked. Defaults to the scene range or preview range.
Distance between keyframes. Can be used to bake on 2s or even bake to subframes.
- Remove Existing Keys
Boolean option that if enabled also removes keys outside the specified baking range.
- Interpolation Type
Choose which interpolation type new keys should have, e.g. Constant or Bezier.
- Bake Modifiers
If true bakes the effect of the modifier stack to keys and deletes the modifier stack. If false, modifiers get disabled before baking, so the resulting keys will behave as if the modifiers didn’t exist.
Discontinuity (Euler) Filter
This operator cleans up Euler rotation channels that suffer from Gimbal Lock. The channels of all three axes of euler rotation need to be selected for the operator to work.
