Timeline

The Timeline editor, identified by a clock icon, is used for manipulating keyframes and scrubbing the playhead.

The Timeline.

The Timeline gives the user a broad overview of a scene's animation, by showing the current frame, the keyframes of the active object, the start and end frames of your animation sequence, as well as markers set by the user.

The Timeline includes Transport Controls, to play, pause, and skip through an animation sequence.

It also includes tools for manipulating Keyframes, Keying Sets, and Markers.

Main View

The main Timeline region displays the animation frames over time.

Here you can see the Keyframes (diamond shapes), Playhead (blue handle), Scrollbar (along the bottom),

Adjusting the View

The Timeline can be panned by holding MMB, then dragging the area left or right.

You can zoom the Timeline by using Ctrl-MMB, the mouse Wheel, or pressing NumpadMinus and NumpadPlus.

You can also use the scrollbars, located at the bottom or the right of the editor, to pan and zoom the view.

Playhead

The Playhead is the blue vertical line with the current frame number at the top.

Playhead.

The Playhead can be set or moved to a new position by pressing or holding LMB in scrubbing area at the top of the timeline.

The Playhead can be moved in single-frame increments by pressing Left or Right, or you can jump to the beginning or end frame by pressing Shift-Left or Shift-Right.

Frame Range

By default, the Frame Range is set to start at frame 1 and end at frame 250. You can change the frame range in the top right of the Timeline header, or in the Output Properties.

Keyframes

For the active and selected objects, keyframes are displayed as diamond shapes.

You can click to select one at a time, or select several by holding Shift, or by dragging a box around the keyframes. You can then move single keys by dragging them, and you can move multiple keys by pressing G and scale them with S.

Only Selected Channels can be enabled. Timeline ‣ View ‣ Only Selected Channels. For Armatures, this will display the object keyframes, and the keyframes for the active and selected pose bones.

Markers

See the Markers page for more information.

Header

Popovers

Playback Popover

The Playback popover contains options controlling the animation playback.

Sync Mode

3D View red FPS.

60:54.75

When you play an animation, the frame rate is displayed at the top left of the 3D View. If the scene is detailed and playback is slower than the set Frame Rate (see Dimensions Panel), these options are used to synchronize the playback.

No Sync

Do not sync, play every frame.

Frame Dropping

Drop frames if playback is too slow.

AV-sync

(Audio/Video Synchronization). Sync to audio clock, dropping frames if playback is slow.

Audio Scrubbing

If your animation has sound, this option plays bits of the sound wave while you move the playhead with LMB or keyboard arrows (like a moving playhead).

Mute Audio

Mute the sound from any audio source.

Subframes

Display and allow changing the current scene sub-frame.

Limit Playhead to Frame Range

Don't allow selecting frames outside of the playback range using the mouse.

Follow Playhead

Animation editors can be setup to always follow the time indicator as animation is being played back. Following will be done when animating and changing frame. When the cursor reaches the end of the screen, the next range of frames of the same width will be displayed.

Active Editor Only

While playing, updates the Timeline, if Animation Editors and All 3D Viewports disabled.

All 3D Viewports

While playing, updates the 3D View and the Timeline.

Animation Editors

While playing, updates the Timeline, Dope Sheet, Graph Editor, Video Sequencer.

Property Editors

When the animation is playing, this will update the property values in the UI.

Image Editors

The Image editor in Mask mode.

Sequencer Editors

While playing, updates the Video Sequencer.

Node Editors

While playing, updates the Node properties for the node editors.

Clip Editors

While playing, updates the Movie Clip Editor.

Keying Popover

The Keying popover contains options that affect keyframe insertion.

Active Keying Set

Timeline Keying Sets.

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 panels Properties ‣ Scene ‣ Keying Sets + Active Keying Set.

Insert Keyframes (plus icon)

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

Delete Keyframes (minus icon)

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

New Keyframe Type

Keyframe Types on insertion.

Auto-Keyframing Mode

This controls how the auto keyframe mode works. Only one mode can be used at a time.

Add & Replace

Add or replace existing keyframes.

Replace

Only replace existing keyframes.

Auto Keying Set (two keys icon)

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

Layered Recording

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

Cycle-Aware Keying

When inserting keyframes into trivially cyclic curves, special handling is applied to preserve the cycle integrity (most useful while tweaking an established cycle):

• If a key insertion is attempted outside of the main time range of the cycle, it is remapped back inside the range.
• When overwriting one of the end keys, the other one is updated appropriately.

Menus

View Menu

The View Menu controls what you see, and what it looks like.

Show Seconds Ctrl-T

Whether to show the time in the X axis and the Playhead as frames (based on the FPS) or as seconds.

Lock Time to Other Windows

It synchronizes the horizontal panning and scale of the current editor with the other editors (Graph, Dope Sheet, NLA) when this option is set. That way you always have these editors showing an identical part of the time you work on.

Show Frame Number Indicator

This will display the current frame or seconds on the Playhead.

Only Keyframes from Selected Channels

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

Cache

Show Cache

Show all enabled types.

Softbody, Particles, Cloth, Smoke, Dynamic Paint, Rigid Body.

Timeline Cache.

View All Home

Maximize the area based on the Animation Range.

View Frame Numpad0

Centers the Timeline to the Playhead.

Bind Camera to Markers Ctrl-B

This is used to switch cameras during animation. It binds the active camera to the selected markers. First select a camera. Then select the marker(s). Then use the tool.

Markers Menu

Markers are used to denote frames with key points or significant events within an animation. Like with most animation editors, markers are shown at the bottom of the editor.

Markers in animation editor.

For descriptions of the different marker tools see Editing Markers.

Header Controls

Timeline header controls.

1. Popovers for Playback and Keying, 2. Transport Controls, 3.Frame Controls

Transport Controls

These buttons are used to set, play, rewind, the Playhead.

Transport controls.

Jump to start (⏮) Shift-Ctrl-Down, Shift-Left

This sets the cursor to the start of frame range.

Jump to previous keyframe (⏪︎) Down

This sets the cursor to the previous keyframe.

Rewind (◀) Shift-Alt-A

This plays the animation sequence in reverse. When playing the play buttons switch to a pause button.

Play (▶) Alt-A

This plays the animation sequence. When playing the play buttons switch to a pause button.

Jump to next keyframe (⏩︎) Up

This sets the cursor to the next keyframe.

Jump to end (⏭) Shift-Ctrl-Up, Shift-Right

This sets the cursor to the end of frame range.

Pause (⏸) Alt-A

This stops the animation.

Frame Controls

Current Frame Alt-Wheel

The current frame of the animation/playback range. Also the position of the Playhead.

Preview Range (clock icon)

This is a temporary frame range used for previewing a smaller part of the full range. The preview range only affects the viewport, not the rendered output. See Preview Range.

Start Frame

The start frame of the animation/playback range.

End Frame

The end frame of the animation/playback range.

Keyframe Control

Auto Keyframe

Timeline Auto Keyframe.

The record button enables 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 Playhead 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. Other use cases are Fly/Walk Mode to record the walk/flight path and Lock Camera to View to record the navigation in camera view.

注釈

Note that Auto Keyframe only works for transform properties (objects and bones), in the 3D Views (i.e. you can't use it e.g. to animate the colors of a material in the Properties editor...).
