About the timeline

The timeline in Adobe Animate organizes and controls a document's content over time in layers and frames. Like a movie film, Animate documents divide lengths of time into frames. Layers are like multiple filmstrips stacked on top of one another, each containing a different image that appears on the Stage. The major components of the Timeline are layers, frames, and the playhead.

Timeline

The timeline shows where animation occurs in a document, including frame-by-frame animation, tweened animation, and motion paths. Controls in the layers section of the timeline let you hide, show, lock, or unlock layers, and display layer content as outlines. You can drag timeline frames to a new location on the same layer or to a different layer.

Modern Timeline

Timeline panel’s look and feel is enhanced including clear frame interval representation, better readability of frame and time marker, enhanced onion skinning, buttons for creating keyframes, blank frames and so on.

Camera

To enable or disable camera, click teh camera button.

Layer parenting view

It displays the parenting hierarchy of layers.

Layer depth

It creates a layer depth panel and allows you to modify the depth of active layer provided in the list. 

Note:

When an animation is played, the actual frame rate is displayed. This frame rate can differ from the document’s frame rate setting if the computer cannot calculate and display the animation quickly.

Onion skinning

Onion skinning has been revamped and made simpler. You can enable onion skinning by clicking on the onion skin button. Onion Skinning is further enhanced to selectively exclude (and include) frames by right click on any onion skin frame within the onion skin range. 

Onion skinning main

Do one of the following:

  • Click the Onion Skin button  to enable and disable onion skinning. When enabled, All frames between the Start Onion Skin and End Onion Skin markers (in the timeline header) are superimposed as one frame in the Document window.
  • Click and hold the mouse on the Onion Skin button  to view and select the options like selected range, all frames, anchor markers and advance settings.
  • Select the Onion skin icon  (the icon to the left of the Loop icon) in the timeline. 

Some of the onion skin parameters in this panel are existing features like outline mode, onion skin previous/future frame color preference, anchor markers.

  • Keyframe only mode: Render only keyframes in onion skin range, that is skip between frames of tween.
  • Starting Opacity: Opacity of first onion skin frame on either side of active frame.
  • Decrease by: Percentage delta decrease across every onion skin frame.
  • Constraints: Range of previous and next frames are same when constraints are enabled, unless, user edits the range from timeline.

For more information, see Using Onion skinning.

Changing the appearance of the timeline

By default, the timeline appears below the main document window. To change its position, detach the timeline from the document window and float it in its own window. You can dock it to any other panel of your choice. You can also hide the timeline.

To change the number of layers and frames that are visible, resize the timeline. To view extra layers when the timeline contains more layers than can be displayed, use the scroll bars on the right side of the timeline.

Dragging the Timeline

  • To move the timeline when it is docked to the document window, drag the title bar tab at the upper-left corner of the timeline.

  • To dock an undocked timeline to the application window, drag the title bar tab to the top or bottom of the document window.

  • To dock an undocked timeline to other panels, drag the timeline title bar tab to the location you choose. To prevent the timeline from docking to other panels, press control key while you drag. A blue bar appears to indicate where the timeline will dock.

  • To lengthen or shorten layer name fields in the timeline panel, drag the bar separating the layer names and the frames portions of the timeline.

Customizing the timeline view

  1. To display the Frame View pop‑up menu, click Frame View in the upper-right corner of the Timeline.

  2. Select from the following options:

    • To change the size of layers, select Large, Medium, or Short. (The Large frame-width setting is useful for viewing the details of sound waveforms.
    • To display thumbnails of the content of each frame scaled to fit the timeline frames, select Preview. This preview can cause the apparent content size to vary and requires extra screen space.
    • To move the Timeline Controls to the top or bottom, select Header Top or Header Bottom, respectively.
    • To zoom in and zoom out the Timeline, use the Timeline resize view slider bar.

Set layer opacity

Do one of the following:

  • To set the visibility to opacity, use shift+click the eye column in the timeline.
  • Double-click the layer’s icon (the icon to the left of the layer name) in the Timeline.
  • Right-click (Windows) or Control+click (Macintosh) the layer name and select Properties from the context menu. In the Layer Properties dialog box, select Visibility>Opacity.
  • Right-click (Windows) or Control+click (Macintosh) the layer name and select Show Others as Transparent.

Resize the timeline panel

  • If the timeline is docked to the main application window, drag the bar separating the timeline from the stage area.

  • If the timeline is not docked to the main application window, drag the lower-right corner (Windows) or the size box in the lower-right corner (Macintosh).

The blue playhead at the top of the timeline moves as a document plays to indicate the current frame displayed on the Stage. The timeline header shows the frame numbers of the animation. To display a frame on the stage, move the playhead to the frame in the timeline.

To display a specific frame when you are working with many frames, move the playhead along the timeline.

  • To go to a frame, click the frame’s location in the timeline header, or drag the playhead to the desired position.

  • To center the timeline on the current frame, click the Center Frame button at the bottom of the timeline.
  • Now, loop range can be created by just dragging over the loop section. It allows you to export the frames (as movie or video) in selected range.
  • With the loop option turned on in the timeline, you can also loop streaming audio within a range of frames along with other animations.

Viewing time along with frames

The timeline displays the time in seconds along with the frame numbers. This feature allows faster conversion from frames to time and also keeps you aware of the frames per second (fps) value you have set throughout the animation process. 

In the following screenshot, the timeline displays 20 frames per second (fps):

Managing animation speed

You can manage animation speed by scaling the frame spans, by animating based on time intervals, or you can extend and compress animations by using time controls. 

Scale the frame spans

You can change frames per second (fps) for your animation without having to change the animation speed. Use the Scale Frame Spans option as you change fps to keep the time intact.

Convert to Frame-by-Frame animation option is available in Modify menu. You can also assign your desired keys in keyboard shortcut dialog to perform these tasks. 

Extend or compress animations using timeline controls

Now, you can extend the frame duration of selected frames by entering desired number of frames in Expand frame span field. The duration of the selected frames are increased by the number entered in the Expand frame span.

You can extend or reduce time for the selected span on the timeline. Select the frame span and drag the right-side edge of the selected span on timeline, forward or backward. The frames within the timeline are adjusted automatically.

You can replicate your animations multiple times (x2, x3, and so on) by dragging the spans in timeline. You can also compress the frames to their normal position, after extending them. 

Select the frames in timeline, click, and drag the highlighted right-side edge of the selection.
