Timeline Palette

Updated: 10/22/2024

In the timeline palette, you can create motions, play them back, etc.
This page mainly describes the screen layout of the palette.

See the “Displaying and Operating the Timeline Palette” page for basic operations of the timeline palette.

Timeline Palette Screen Layout

Number	Item	Details
A	Playback and timeline movement	Controls related to the playback of the created motion are located in this section.
B	Tracks and properties	This section displays the parameters and display options created in the Modeling View, as well as the properties of the entire track.
C	Timeline	Time, keyframes, timeline display options, etc. are displayed here. Note that the contents displayed in the [Dope Sheet] and [Graph Editor] are different.

Playback and timeline movement

Number	Item	Details
(1)	First frame	Move to the beginning of the Work Area. [Shift] + [Home]
(2)	Previous frame	Move back one frame. [Page Up]
(3)	Playback	Play back. [Enter]
(4)	Next frame	Move forward one frame. [Page Down]
(5)	Last frame	Move to the end point of the Work Area. [Shift] + [End]

Tracks and properties

Number	Item	Details
(1)	Track	The blue bars and area below are the tracks. Tracks are materials such as model files and audio files. Click the left-most triangular button to expand/collapse. (You can expand/collapse all property groups in a track using [Shift] + [Click].) Right-click on the bar to display the following menu. Duplicate Track: Duplicate tracks. Remove Track: Delete tracks. Edit Track Name: You can edit track names as desired. Use File Name: You can revert to the same name as the file name. Import Motion: A motion3.json file can be imported. Click the FA button to open the Form Animation View. See the “About Form Animation (FA)” page for details.
(2)	Property group	The areas indicated by light blue bars in the light theme and green bars in the dark theme are the property groups for that track. The left-most triangular button can be used to expand/collapse. (You can expand/collapse all elements in a property group using [Shift] + [Click].) The items that appear when the image is expanded are properties, such as [Angle X], [Deformer], and [Opacity]. Sliders and values for parameters are shown on the far right. Eye blinking: This will appear when the eye blinking setting is set on the model in the Modeling View. Set this if you want to control eye blinking in the SDK. See “Eye Blinking Setting” for detailed instructions. Lip-sync: This will appear when the lip-sync setting is set on the model in the Modeling View. Set this option if you want to control mouth movements in the SDK or if you want to automatically create lip-syncing from an audio file. See “Creating Scenes with Background Music and Audio” for detailed instructions. Live2D Parameters: The parameters for the model are displayed. This can be operated in the same way as the Parameter palette in the Modeling View. Parameter names can expand the display area. Live2D Parts Visibility: Opacity can be changed for each part. This can be used to switch between multiple patterns of arm parts. Placement & Opacity: You can edit the following items in models and images. [Position] [Scale X, Y] [Rotation] [Anchor Point] [Opacity] [Frame Step] [ArtPath Width Magnification]
(3)	Shy	Show/hide properties in the timeline palette. After clicking the Shy button on the left end of each property to turn it on (hidden), click the Shy button at the top to apply. See “Shy Function” for detailed instructions.
(4)	Freeze	Stop certain properties on the timeline palette to check motions, positions, etc. Click the Freeze button at the left end of each property to turn it on, then click the Freeze button at the top to apply it. See the “Freeze” page for detailed instructions.
(5)	Create new group	If you have a lot of material in use, you can create groups to store and organize your tracks.

Timeline

Dope Sheet display

Create an animation by setting keyframes on the time axis of the timeline.

Number	Item	Details
(1)	Current position (time)	The position of the indicator (11) is displayed in [minutes:seconds:frames].
(2)	Graph Editor	Toggles between Graph Editor display and Dope Sheet display.
(3)	Toggle between frames / timecode	Switch between “sec + frame display” and “total frame display” on the rounded number (7).
(4)	Toggle free / fixed cursor timeline navigation	Turn on to lock the indicator. Normally, clicking anywhere on the timeline will move the indicator to that position, but this feature allows keyframes, etc. to be selected regardless of the indicator’s current position.
(5)	Button to switch between markers and onion skin markers	Toggles between marker and onion skin marker display with this button. Marker: Onion skin marker:
(6)	Recording button for external application integration	Inserts a key in the timeline of the model track with the value of a parameter received from an external application. See “External Application Integration” for details.
(7)	Rounded Number	This is the rounded number of the timeline. It is displayed as “sec:frames” or “total frames.” This display can be switched between time display and frame count display using the toggle button (3). Markers can also be added. See “Marker function” for details.
(8)	Work Area	The area indicated by the blue bar is the Work Area.
(9)	Track	The area indicated by the blue bar is the track, and the green bar below it is the property group. The length of the blue bar indicates the starting and ending points of the displayed element. If a keyframe (10) is created for any of the properties, it will be marked.
(10)	Keyframe	This frame is the point of motion.
(11)	Indicator	The current position on the timeline. Time is indicated in (1).
(12)	Zoom in on the timeline	Reduce/expand the timeline. You can change the zoom level with the [-] and [+] buttons or the slider. The zoom level of the timeline can also be changed by [Alt] + [mouse wheel].
(13)	Adjustment of spacing	Adjust the keyframe spacing of the selection. You can specify a % value for the scale from the [Adjust Spacing] dialog box.
(14)	Grid display	Display vertical lines in the graph area. Line spacing can be selected from [No vertical grid], [Every frame], [Every 5 frames], [sec], or [Frame step].
(15)	Duration	The range up to this point is the duration and represents the length (scale) of the timeline. In the dark-colored area on the right side, duration is shown in “sec + number of frames” and “total frames.”
(16)	Palette Menu	Click to display the timeline palette menu.

See “Displaying and Operating the Timeline Palette” for detailed instructions.

Graph Editor Display

Switch to the [Graph Editor] to display the graph.
Selecting a parameter for which a keyframe is set allows you to edit it.
You can also select multiple parameters, each with a different color for the line.

Number	Item	Details
(1)	Selected parameters	The area highlighted in gray is the parameter being selected.
(2)	Keyframe	The dots are the keyframes.
(3)	Selected keyframes	Clicking on a keyframe to select it changes the shape of the point.
(4)	Resize	Restores the magnification of the curve.
(5)	Grid display	Display vertical lines in the graph area. None: No line is displayed. Every Frame: Displays a line per frame. Every 5 Frames: Displays a line every 5 frames. sec: Displays a line every second. Frame Step: Displays lines at intervals set in Frame Step. See “Frame Step” for detailed instructions.
(6)	Linear	Change the line after the selected keyframe to a straight line.
(7)	Auto smooth	Change the line after the selected keyframe to a curve.
(8)	Step	Interpolate the line after the selected keyframe with a vertical line aligned with the previous key.
(9)	Inverse step	Interpolate the line after the selected keyframe with a vertical line aligned with the previous key.
(10)	Bezier	Create Bezier handles on selected keyframes, allowing them to be edited into freeform curves.

See “Graph Editor” for detailed instructions.
