Graph Editor - Editing

Tools and menus for the F-Curves in the Graph Editor.

By default, when new channels are added, the Graph Editor sets them to Edit Mode. Selected channels can be locked by pressing ⇆ Tab.

Basic Tools

These are some basic tools to modify the curves and keyframes.

Transformations

Active Keyframe Panel.

Grab/Move selected keyframes G

Rotate selected keyframes R

Scale selected keyframes S

Additionally, for translation and scaling, you can lock the transformation along the X (time frame) or Y (value), as usual by pressing X or Y during transformation.

For precise control of the keyframe position and value, you can set values in the Active Keyframe of the Properties Region.

Cursor Value

Snap the selected keyframes to the Cursor.

Nearest Frame

Snap the selected keyframes to their nearest frame individually.

Nearest Second

Nearest Marker

Snap the selected keyframes to their nearest marker individually.

Flatten Handles

Clean Keyframes

Smoothing

(AltO or Key » Smooth Keys) There is also an option to smooth the selected curves , but beware: its algorithm seems to be to divide by two the distance between each keyframe and the average linear value of the curve, without any setting, which gives quite a strong smoothing! Note that the first and last keys seem to be never modified by this tool.

Sampling and Baking Keyframes

Sample Keyframes ⇧ ShiftO: Sampling a set a keyframes replaces interpolated values with a new keyframe for each frame.

Bake Curves AltC: Baking a curve replaces it with a set of sampled points, and removes the ability to edit the curve.
