Getting Started > Content Editing, Composition & Playout

•A Sequences is a timeline based Playback Provider that is hosted by a Playback

•A Sequence contains a collection of Clip Containers (and cues), sorted on different tracks on a timeline

•A Sequence has a default Canvas, but every Clip Container can be assigned to a different Canvas or even Output

•A Sequence can be nested as clip container into another sequence - similar to what you know from subcompositions in other video compositing applications

Working with Sequences

Big Screenshot - Zeigt für das Topic wichtige UI-Element - ein großer und zusammenhänender Überblick soll gegeben werden.

Create a new Sequence

•via the main menu on top: Open "Create" and select "Sequence"

•via the Project Explorer: navigate to the Sequence Category, open context- menu with a right-click and select "Create..."

Clip Containers on Tracks

A Sequence contains different Clip Containers. Tracks help you to arrange Clip Containers and build your show.
Freely move Clip Containers between tracks.

productivity Too much tracks?
Scroll up and down vertical with your mouse wheel. Use + and - to zoom in or out into Playback Editor

background-knowledge Are tracks the same like layers which I already know from other media server software?
No! Tracks are just helpers to order your Clip Containers. Tracks can have some track based settings but there is no layer restriction like other software has. Tracks and Clip Containers are flexible objects - like you may already know from Video editing or compositing software

Change Length and Framerate

•By default, the length of each Sequence is set to 10 Minutes.

•You are able to change this length into Inspector Settings of your Sequence:
Select the Sequence into Project Explorer.
Focus it into an Inspector and set the Playback provider time into the settings tab there

Options in the Context menu

By a right-click with your mouse into the Playback editor, the context menu offers you different options to select clip Containers, create or insert new tracks or to create other items.

Access all items of a Sequence in Project Explorer

All tracks, Cues and clip containers are also accessible as child elements of your Sequence into Project Explorer
You are able to select them there to focus an item into Inspector or to delete.

productivity Lost Clip Containers
Searching for a Clip Container that is lost? Or to small to select into Playback Editor?
Just select it into Project Explorer and open the context menu.
The option "reset to clip length" reset the Container to its default value again.

Cues

Settings

Standard Mode

	Audio Offset	Defines a Audio Offset for your whole Sequence in milliseconds. All Audio is shifted from video for this offset Set to a value to compensate a general audio shift from video content Please note: There is also an option to set this offset per System
	AutoFade	Auto Fade Options and Settings. For each Clip Container into a Sequence there is an Auto Fade Wizard which automatically generates Keyframes to fade in/out video/audio. Set default settings for the whole Sequence here. Enable "Apply on new Clip" to add this Keyframes for each new Clip Container
	Content Drop Mode	Defines how defines how a selection of content that is dragged from Project Explorer into your Sequence will be arranged as Clip Containers. Options: Vertical (Default): As Clip Containers, each on a new track at the same timecode Horizontal: ext to each other on the same Track
	Default Canvas	Specifies the Canvas that is set as default for each new Clip Container into this Sequence. You can change this Canvas by drag and drop another Canvas with your Mouse from Project Explorer to this Property field.
	Default Cue Mode	Sets a default Cue Mode for this Sequence. Every new Cue which will be added to this Sequence will have this default mode
	Enabled	Enables or Disables rendering of the whole Sequence
	Playback Provider Time	Length: Defines the length of your Sequence. After a change of this value also the timeline length into Playback editor is adapted to this new value FPS: Defines the frames per second grid on the Playback Editor's timeline. This value only affects the user's timeline with starting points, cues, synchronization, etc. The rendering engine, however, pushes all frames of your content to your GPU.
	Template Clip	Set a Template for a Clip Container. For each new Content that will be added to the Sequence a new Clip Container based on this template will be created. Drag a Clip with your mouse from Project Explorer to this property field.
	User Properties	Enter some User Properties for this Sequence

warning Changing the sequence framerate may shift already existing cues!
When changing the frame rate of a sequence that already has cues in the timeline, all cues will be shifted to the next valid time code frame.
Depending on your changes, this recalculation may cause a minimal shift in cues - please inspect all your cue times after changing the framerate.

Shortcuts

•Each editor window in VERTEX has got a varying set of shortcuts that are automatically created and updated.

•Press the F1 Key to open a list of shortcuts corresponding to the current window/ editor in focus.

Focus Playback Editor and Press F1 Key.
A window with all available shortcuts for your Sequence opens.

Nested Sequence Content

•VERTEX allows you to use a Sequence as Content into another Sequence.

•This gives you as user the capability to make sub-compositions and use them as content into another sequence

•The capability and the performance limit of nesting depend on your hardware. In general: Nested sequences need more render performance as regular simple video content.

How To Create

There are two different ways to nest a Sequence into another one:

1.Drag a Sequence with your mouse from Project Explorer into the Playback Editor.
VERTEX creates a Clip Container for this Sequence and a Nested Sequence Content into the content section of your Project Explorer.
You can identify a Nested Sequence Content by the layer symbol

information Restrictions for Nesting
Currently and all kind of Devices are not supported for Nested Sequence Content.
We will work on this for future release.
A circular reference is not possible: Nested Sequence Content from a Sequence 1 cannot be used into Sequence 1.

2.Use the Context menu into Project Explorer and create a Nested Sequence Content
One created, this Nested Sequence Content is listed into the Content Section of your Project Explorer and can be used
as every other Content into a Clip Container of another Sequence

warning Performance
VERTEX is a real time software - please keep in mind that using nested sequence content costs you more System performance.
Each nested Sequence has impact on the Render Pipeline. The performance needs of the Render Engine increases with deeper nesting, repeated or multiple nesting.
