Page status (reviewing guidelines) Text Some parts need to be updated, wiki notes have been added below. Proposed fixes: none

The Timeline

The Timeline window, identified by a clock icon, is shown by default at the bottom of the screen.

The Timeline is not much of an editor, but more of a information and control window.

Here you can have an overview of the animation part of your scene

What is the current time frame, either in frames or in seconds, where are the keyframes of the active object, the start and end frames of your animation, markers, etc...

The Timeline has Player Controls, to play, pause the animation, and to skip though parts of the scene.

It also has some tools for Keyframes, Keying Sets, and Markers.

Timeline Elements

Time Cursor

Time Cursor

The Time Cursor is the green line, its used to set and display the current time frame.

The Time Cursor can be set or moved to a new position by pressing or holding LMB in the Timeline window.

The Time Cursor can be moved in steps by pressing Arrow left or Arrow right, or in steps of 10 frames by pressing ⇧ ShiftArrow up or ⇧ ShiftArrow down.

Keyframes

For the active and selected objects, keyframes are displayed as a yellow line.

For Armatures, the object keyframes and the pose bones keyframes are drawn.

Only Selected Channels can be enabled. Timeline > View > Only Selected Channels.

For Armatures, this will draw the object keyframes, and the keyframes for the active and selected pose bones.

Markers

Markers are the small triangles, with their name near them.

Markers are usually used to identify key parts of the animation.

Markers can be selected by pressing RMB or ⇧ ShiftRMB to select more.

This enables Frame Dropping from the Playback Menu.

V Keyframe Control

Timeline Auto Keyframe.

Auto Keyframe

The "Record" red-dot button enables something called Auto Keyframe: It will add and/or replace existing keyframes for the active object when you transform it in the 3D view.

For example, when enabled, first set the Time Cursor to the desired frame, then move an object in the 3d view, or set a new value for a property in the UI.

When you set a new value for the properties, blender will add keyframes on the current frame for the transform properties.

Auto Keying Set - Optional if Auto Keyframe enabled.

Auto Keyframe will insert new keyframes for the properties in the active Keying Set.

Note that Auto Keyframe only works for transform properties (objects and bones), in the 3D views (i.e. you cant use it e.g. to animate the colors of a material in the Properties window…).

Timeline Layered.

Layered - Optional while playback.

Adds a new NLA Track + Strip for every loop/pass made over the animation to allow non-destructive tweaking.

Timeline Keying Sets.

Active Keying Set

Keying Sets are a set of keyframe channels in one.

They are made so the user can record multiple properties at the same time.

With a keying set selected, when you insert a keyframe, blender will add keyframes for the properties in the active Keying Set.

There are some built in keying sets, 'LocRotScale', and also custom keying sets.

Custom keying sets can be defined in the in the panels Properties > Scene > Keying Sets + Active Keying Set.

Insert Keyframes

Insert keyframes on the current frame for the properties in the active Keying Set.

Delete Keyframes

Delete keyframes on the current frame for the properties in the active Keying Set.

User Preferences

Some related user preferences from the Editing tab.

Playback

Allow Negative Frames

Time Cursor can be set to negative frames with mouse or keyboard.

When using Use Preview Range, this also allows playback.

Keyframing

Visual Keying

When an object is using constraints, the objects property value doesnt actually change.

Visual Keying will add keyframes to the object property, with a value based on the visual transformation from the constraint.

Only Insert Needed

This will only insert keyframes if the value of the propery is different.

Auto Keyframing

Enable Auto Keyframe by default for new scenes.

Show Auto Keying Warning

Displays a warning at the top right of the 3D View, when moving objects, if Auto Keyframe is on.

Only Insert Available

With Auto Keyframe enabled, this will only add keyframes to channel F-Curves that already exist.
