Editing
Delete Channels
Reference
Menu:
Channel ‣ Delete Channels
Shortcut:
X
Deletes the whole channel from the current action (i.e. unlink the underlying F-Curve data-block from this action data-block).
Warning
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/Group Channels
Reference
Menu:
Channel ‣ Un/Group Channels
Shortcut:
Ctrl-Alt-G, Ctrl-G
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
Reference
Menu:
Channel ‣ Toggle/Enable/Disable Channel Settings
Shortcut:
Shift-W, Shift-Ctrl-W, Alt-W
Enable/disable a channel’s setting (selected in the menu that pops up).
Protect, Mute
Todo.
Toggle Channel Editability
Reference
Menu:
Channel ‣ Toggle Channel Editability
Shortcut:
Tab
Locks or unlocks a channel for editing.
Extrapolation Mode
Reference
Menu:
Channel ‣ Extrapolation Mode
Shortcut:
Shift-E
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:
Constant:
Constant extrapolation.
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).
Linear:
Linear extrapolation.
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
Reference
Menu:
Channel ‣ Add F-Curve Modifier
Shortcut:
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 Sidebar ‣ Modifiers tab.
Show/Hide
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.
Expand/Collapse Channels
Reference
Menu:
Channel ‣ Expand/Collapse Channels
Shortcut:
NumpadPlus, NumpadMinus
Expands or collapses selected channels.
Move
Reference
Menu:
Channel ‣ Move…
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
Reference
Menu:
Channel ‣ Revive Disabled F-Curves
Clears “disabled” tag from all F-Curves to get broken F-Curves working again.
Frame Selected Channels
Reference
Menu:
Channel ‣ Frame Selected Channels
Shortcut:
NumpadPeriod
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
Reference
Menu:
Channel ‣ Keys to Samples
Shortcut:
Alt-C
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
Reference
Menu:
Channel ‣ 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
Reference
Menu:
Channel ‣ 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.
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.
Bake Channels
Reference
Menu:
Channel ‣ Bake Channels
The Bake Channels operator creates new keyframes on the F-Curves of channels that are selected in the channel box.
Range
The range that will be baked. Defaults to the scene range or preview range.
Step
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
Reference
Menu:
Channel ‣ 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.
