Timeline

The Timeline is one of the interface panels where you can place and visualize different elements chronologically. Each element is represented by a line called a "layer", which together form a layer stack.

Two Key Sections

The Timeline panel is split into two main sections:

You can adust the space these two sections take up by clicking on the separator and dragging it left and right.

Timeline controllers

Here is a breakdown of the first line of Timeline controllers:

Just below:

Mutiple Timelines and Viewers

You can display multiple Timelines at the same time by simply adding new panels to your workspace, using the Panels > Timeline > New timeline menu, in the top bar. You can move this new panel to the desired location and select the composition you want to look over from the list.

You can even display two or more Timelines that refer to the same composition. This way, you'll be able to look over different parts of the stack or different timing in the dope sheet.

Assigning Timelines to Viewers:

When two Viewers and two Timelines are displayed on the screen, it's important to determine which Timeline controls which Viewer. At the bottom of each Viewer there is a Timeline selector, as shown below:

The selector contains a list of all visible Timelines on screen. This lets you choose which Timeline's current time will define the image to be rendered in a specific Viewer.

Note:

The composition connected to a Timeline is not necessarily the same as the one connected to the Viewer using the selector at the top of the Viewer. This makes it possible to render the same composition in several formats at the same time, or to render several compositions driven by the same Timeline.

Populating the Stack:

In the Stack on the left, you can stack elements according to the principle of layer stacking.
To add new layers to the Stack, you can:

Selecting and Reordering layers:

Selecting layers is similar to the process of selecting files in your file browser, with some minor differences:

Note: The layer that appears brighter than the others is the Active Layer.

Selection Order:

When you press ctrl/cmd and click on layers, the selection order is retained. When you want to Copy/Paste or Duplicate a group of layers, the clicking order will define the stacking order of the new layers.
The same is true when using the shift key:

All layers in the current stack can be:

Note:

When you press ctrl/cmd + a, the selection order is defined from top to bottom. So, if you Copy/Paste these layers, the original stacking order will be retained.

Reordering layers:

Since Autograph is available on Windows, Mac, and Linux, it is important to accommodate all types of systems that do not have identical keyboard shortcut policies. Depending on the mouse or tablet used, certain combinations are sometimes easier to use on certain systems.
This is why several shortcuts are available for the same action:

Scrolling through the stack:

You can also use the scroll bar on the right.

Moving in the Dope sheet:

Warning:

Shortcuts in Autograph are contextual and dependent on mouse position. These shortcuts are valid when your mouse cursor is over the Timeline.

Modules and tools

The dope sheet is situated on the right part of the Timeline by default. This module lets you manage the timing of composition elements.

The right part of the Timeline may vary depending on the module used and the side panels.
Buttons at the top-right of the header allow you to switch from one module to another or display additional panels named Dock:

The buttons in this header are listed below, from left to right:

Multi Edit Mode selector is one of the tools attached to the dope sheet. Switching to the Curve editor module will display other tools on the left.

Filtering the Stack

The Stack contains many items, and unfolding hundreds of parameters can make navigation difficult. Autograph offers a filter system to easily access the most used parameters or reduce the number of layers displayed in the Stack.

Filtering layers by name:

At the bottom of the Stack, there is a field to define a string. If this string can be found in the name of a layer - whether it is at the beginning, middle, or end - this layer will always be visible. All layers that do not contain this string will be visually removed from the Stack, although Autograph will still use them for calculating images visible in the Viewer.

The string in the layer names will be highlighted in green:

Whenever a filter is active, whether it is the name search or the other filters described below, a red X appears at the bottom right of the stack.
Click on it or press alt/opt + f to remove any filter applied to the stack.

Note:

When using filters, you may also notice that some indexes are missing in the layer numbering on the left of the Stack. This is another indication that a filter is currently in use.

FILTERS SHORCUTS

After selecting a few layers in the Stack, you can apply filters to display only certain parameters for this selection. If nothing is selected, all layers will be affected. These filters may or may not be cumulative.
To add a filter to the existing ones, just press the shift key in the menu or use a shortcut. Without this key, adding a new filter will remove the previous ones.

Filtering layers containing keyframes:

By clicking on the diamond at the bottom right of the Stack, only the parameters containing keyframes will be displayed. The shortcut for this action is u.

Tip:Pressing the same key assigned to a filter twice will delete that filter. So, press u twice to show then hide keyframes. This tip applies to all filters.

Filtering layers by parameter type:

Next to the keyframe filter button, a drop-down menu gives you access to the transformation parameter filters as well as additional options.

Folding/unfolding layers and parameters

By pressing the shortcut e, you can fold or unfold the selected layers.

During this process, if you have previously unfolded specific parameters, such as a layer Source, Autograph will remember which parameters were unfolded. This way, you can fold a layer just to make more room in the Stack, then unfold it and return to the same viewing configuration.
