The '''Timeline''' window is the workspace of a composition. In it, effects are arranged in time and across layers, and playback is controlled from here. Everything you see in the '''Mapping''' field and in the '''3D View''' window is the state of the timeline at the moment where the time cursor currently stands.

This article describes the window itself: what is located where, what its buttons do, and how to navigate the time scale. For how to move and trim effects, see [[Arranging Effects in Time]]; for how to animate their parameters, see [[Keyframes and Effect Parameters]].

== How to open the window ==

By default, the '''Timeline''' occupies the bottom part of the program window, across its full width. If the window has been closed, enable it via the '''Window''' menu → '''Timeline''' — the item has a checkmark. Like any program window, the timeline can be dragged by its title bar to another location, made floating, or resized; window placement is saved in the workspace (see [[Workspace]]).

The timeline always shows a single composition — the one opened with a double click in the '''Compositions''' window. While no composition is open, the window is empty.

== What the window consists of ==

The window is divided vertically into two parts, with a movable border between them: drag it with the mouse to widen the list, or, conversely, give more space to the time scale.

On the left, top to bottom:

* a button panel — opening the '''Effects''' window and importing files;
* the name of the open composition and a button for its settings;
* the list of layouts and the effects contained in them.

On the right, top to bottom:

* the playback panel — start buttons, current time, composition duration;
* the time ruler and tracks: each row of the list on the left has its own track on the right;
* the preview strip — a narrow strip at the very bottom that sets the visible time span.

The rows on the left and the tracks on the right always line up exactly opposite each other: collapse a layout — its rows and their tracks disappear together; scroll the list — the tracks scroll along with it.

== Button panel ==

{| class="wikitable"
! Button !! What it does
|-
| '''Effects''' || Opens and closes the '''Effects''' window — the library from which effects are added to the composition. The button stays pressed while the window is open. See [[Библиотека эффектов]]
|-
| '''Import Image''' || Adds an image to the composition — it becomes a regular effect on the timeline
|-
| '''Import Video''' || Adds a video file or an image sequence (a folder with numbered frames). For a video file, an import window with parameters opens; a sequence is added immediately
|-
| '''Import Audio''' || Adds an audio track. It appears as a separate row in the list, and is drawn as a waveform on the scale — convenient for laying out effects to music
|}

Imported files are not embedded into the project — only the path to them is stored. If the project needs to be moved to another computer, collect it with the '''File''' → '''Collect Project''' command.

== Composition name and its settings ==

Below the button panel, the name of the open composition is shown — this makes it easier not to confuse which one you are currently working in.

The button to the right of the name opens '''Composition Settings''': the composition's parameters appear in the '''Properties''' window — duration, frame rate, looping, infinity, comment, and color filtering. For more, see [[Composition Settings]].

== List of layouts and effects ==

The list is organized as a tree. The top level is the composition's layouts, inside each layout are its effects, and inside an effect are its parameters.

* The '''triangle''' to the left of the name expands and collapses the row. Under a layout it shows the effects; under an effect, groups of its parameters with keyframe tracks. The program remembers the collapsed state of layouts separately for each composition and saves it in the project.
* The '''checkbox''' to the left of the name turns the element on and off. An unchecked box on an effect — the effect does not play and is not included in export; unchecked on a layout — the entire layout is silent.
* '''Name.''' Clicking a row selects the element and shows its parameters in the '''Properties''' window. Renaming — press '''F2''': type the new name and press '''Enter''' ('''Esc''' cancels the input).
* '''To the right of an effect's name''' are the blend mode list and the opacity control — how this effect is composited over the ones below it. See [[Режимы смешивания]].
* '''Order.''' Rows are reordered by dragging. The order sets the compositing: the one above is drawn on top of those below. Dragging also moves an effect to another layout — see [[Moving Effects Between Layouts]].
* '''Right-clicking''' an effect row opens a menu with the items '''Clone''' (a copy of the effect next to the original), '''Duplicate''', and '''Delete'''. Right-clicking a layout — '''Rename''' and '''Delete'''.
* '''Delete''' removes the selected effects. An accidental deletion is undone with '''Ctrl+Z'''.

The list scrolls with the mouse wheel and its own scroll bar; the tracks on the right scroll together with it.

== Playback panel ==

{| class="wikitable"
! Button !! What it does
|-
| '''Home''' || Puts the time cursor at the start of the composition and scrolls the scale there too. The '''Home''' key does the same
|-
| '''Play / Pause''' || Starts and pauses the composition. Key — '''Spacebar'''. When paused, the cursor stays in place
|-
| '''Stop''' || Stops playback and returns the cursor to the start
|-
| '''Step Back''' and '''Step Forward''' || Move the cursor exactly one frame. Useful for checking whether an effect starts exactly where intended
|-
| '''Current Time''' || Time in the format ''hours:minutes:seconds:frames''. You can enter a time manually into this field — the cursor will jump to the specified point. Below it is the current frame number
|-
| '''Loop''' || Once it reaches the end, the composition starts over. Unavailable when infinity is enabled
|-
| '''Duration''' || An underlined value showing the composition's duration. Clicking it opens the '''Set Duration''' window, where duration and frame rate are set
|-
| '''Infinity''' || The composition plays with no time limit; the duration value is not used in this case
|}

Some buttons can be hidden to save space. Right-click the playback panel — the menu lets you toggle '''Show Stop Button''', '''Show Home Button''', '''Show Step Buttons''', '''Show Opacity Master''', and '''Show Fixture Highlight Button'''. This setting is shared across the program and is remembered between launches.

== Opacity master and fixture highlighting ==

Two more tools are located on the right side of the playback panel.

The '''Opacity Master''' is an overall brightness slider for everything sent to the fixtures. The default value is maximum. It acts on top of all compositions and effects at once, so it is convenient for dimming the entire venue as a whole without touching the project. This slider has nothing to do with composition settings: color filtering is set separately for each composition (see [[Composition Settings]]).

'''Highlight Fixtures and DMX Data''' is a toggle button: while it is pressed, the selected fixtures are highlighted both in the program and on the actual venue, to help you understand which fixture in the project corresponds to which luminaire on site. The small button with an arrow next to it opens the highlight settings.

== Time ruler and time cursor ==

The top strip of the right side is the time ruler. Its labels change with the zoom level: at high zoom-in these are frames ('''12f'''), at normal zoom — seconds ('''5s'''), on long compositions — minutes ('''10m''') and hours ('''1h''').

The vertical orange line is the time cursor. It shows the moment of the composition that is currently drawn in the '''Mapping''' field and in the '''3D View'''.

* Click the ruler — the cursor jumps to that point.
* Without releasing the button, drag the mouse along the ruler — the composition will be "scrubbed" by hand.
* The cursor always lands exactly on a frame: you cannot land between frames.
* '''Ctrl + →''' and '''Ctrl + ←''' move the cursor by one frame, '''Ctrl + Shift + →''' and '''Ctrl + Shift + ←''' — by ten frames at once.

== Tracks ==

To the right of the list, on the time scale, each effect occupies its own bar: its left edge is the start of the effect, the right edge is the end. The bar under the mouse cursor lightens slightly; the selected one is noticeably lighter than the rest.

* Clicking a bar selects the effect and opens its parameters in the '''Properties''' window.
* '''Ctrl + click''' (or '''Shift + click''') adds the effect to the selection; clicking an empty area clears the selection.
* Right-clicking a bar opens a menu: '''Set time''' — exact entry of the start, end, and duration, '''Copy''' — copies the selected effects, '''Delete''' — deletes them.
* Dragging moves the bar in time, and dragging its edges stretches or shortens it. For details, see [[Arranging Effects in Time]].

For an expanded effect, parameter tracks are located below its bar — keyframes live on them, see [[Keyframes and Effect Parameters]].

== Zoom and navigating the scale ==

{| class="wikitable"
! Action !! How to do it
|-
| Zoom time in and out || '''Mouse wheel''' over the scale. The zoom changes relative to the pointer, so aim it at the area you need
|-
| Scroll the scale || Drag with the '''mouse wheel''' held down (or the right button): horizontally scrolls time, vertically scrolls the list
|-
| Show a specific span || The preview strip at the bottom of the window: the side handles set which part of the composition is visible on the scale, the middle one moves that span as a whole
|-
| Return to the start / to the end || The '''Home''' and '''End''' keys — the cursor and the scale jump to the start or the end of the composition
|}

The scale's zoom level is only a view setting: it affects neither the effects nor the export.

== Hotkeys ==

{| class="wikitable"
! Action !! Keys
|-
| Play / pause || '''Spacebar'''
|-
| Cursor to the start / end of the composition || '''Home''' / '''End'''
|-
| Step one frame forward / back || '''Ctrl + →''' / '''Ctrl + ←'''
|-
| Step 10 frames forward / back || '''Ctrl + Shift + →''' / '''Ctrl + Shift + ←'''
|-
| Snapping while dragging effects || hold '''Shift'''
|-
| Rename the selected list item || '''F2'''
|-
| Delete the selected effects || '''Delete'''
|-
| Undo / redo an action || '''Ctrl+Z''' / '''Ctrl+Shift+Z'''
|}

The full list of shortcuts is available in the program itself: '''Help''' → '''Hotkeys'''.

== If something can't be found ==

* '''The window is empty.''' No composition is open: go to the '''Compositions''' window and double-click the card you need.
* '''A layout's effects aren't visible.''' Its row is collapsed — expand it with the triangle to the left of the name.
* '''A bar you need isn't visible.''' It's most likely outside the visible time span: zoom out with the mouse wheel or drag out the preview strip's handles.
* '''The playback panel or its buttons disappeared.''' The '''Stop''', '''Home''', and step buttons, the opacity master, and fixture highlighting are toggled with a right click on the playback panel.
* '''The timeline window got closed.''' '''Window''' menu → '''Timeline'''.
