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.

Channel ‣ Discontinuity (Euler) Filter
