The ~sedna presenter application is comprised of two main applications: Presenter Creator and Presenter Player.

  • Presenter Creator is the content management component of the software suite. 
    • In this application, you'll create your digital signage by creating, structuring, and scheduling your content into projects 
    • ~Sedna Project files have the extension .presenter
    • The presenter project file you create will contain all of the assets and scheduling needed for playback

  • Presenter Player is the playback application for presenter project files.
    • This application plays the signage projects that you have created using Presenter Creator for viewers to see. 
    • Once the project has been published successfully from the Creator to the Player - the player does not require communication to the Creator.

Quick-Start and Workflow


Step 1: Import Assets into Presenter Creator

Method A: Importing by Drag and Drop

Simply drag media files from Finder onto the Presenter Creator interface. You can also drag and drop entire folders in this way.

Method B: Importing with the Open Dialog

Choose Add → Assets → Media → and the kind of file you want to import as an asset. Alternatively, you can click on the Cancel_Button button at the bottom of the assets panel. An open dialog appears where you can choose the files that you wish to add.

Larger files may take slightly longer to import and you can see their progress in the status display at the top of the interface.

Tip: You can create a Group in which to organize your Assets by clicking on the  Cancel_Button button and selecting "Group"


Step 2: Create Playlists or Arrangements

Playlist - a playlist defines the order of content as well as the start, end, and duration of each piece of content. Playlists only playback one piece of content at a time. 

Arrangement - an arrangement is a composition of content which allows control over position and layering of content on the screen. Arrangements allow playback of multiple pieces of content simultaneously. For Example - a text ticker at the bottom of the screen and video above. 

Note: Content can be assets imported or generated by presenter creator as well as other playlists, arrangements, videowalls, or multiscreen assets. There is no limit to the amount of playlists or arrangements you can create.

In this Quick-Start we will create a Playlist:

Click the Cancel_Button  Icon at the Bottom of the Arrangements & Playlists pane and select "Playlist" 

Click Yes to the prompt asking if you'd like to set this playlist as default content. Default content will is the content which will play 24/7. (Your playlist will loop automatically). We can change which playlist is default later by pressing the control key, clicking on the playlist, and selecting Default. You'll notice the playlist has small icon next to it of a flag, which indicates default content. 

Optionally - Content which is placed on the schedule in Step 3 will override default content. 

Drag Assets from the Assets Pane to the Playlist in the Center Pane. You can re-order content just by clicking on the row and dragging the content up or down. To delete content from your playlist - press the delete key. Deleting content from your playlist won't delete the content from your project. It will remain in the assets pane and thus in your project.

You'll notice when you click on content within the playlist, the Inspector pane changes on the right panel revealing multiple options. 

A few you might find helpful: 

  • Duration: You can adjust the duration manually by entering a time in this field or click the number to the right of Loop to define how many times this content should loop.
  • Crossfade: If you have a content you'd like to cross fade between, just press the command key to select the content and drag the crossfade slider to crossfade between the clips.
  • Fill Behavior: Content isn't always sized to the exact dimensions of your screen. Adjusting the Fill mode will help adjust and scale content to fit. 


Step 3: Schedule Content 

Continue to Step 4 if you wish your playlist to loop continuously every day. 

This Step is only required If you do not wish your playlist to loop continuously and wish to schedule a playlist for a specific time or day. 

Remember that the playlist you made in Step 2 will play when content is not explicitly scheduled since it is default content. 

Scheduling a playlist for a specific day 

Drag the playlist from the left "Playlists and Arrangements" pane to the day you wish the content to play. The following dialog appears - 

Click OK to schedule the playlist for one day or select Repeat and adjust the parameters. 

Scheduling a playlist for a specific time on a day 

Double click the date you wish to schedule the playlist and drag the playlist from the left "Playlists and Arrangements" pane to the time on the schedule in which you wish the content to play. You can adjust the start time and duration of the playlist by using the inspector or dragging the edges of the playlist on the schedule. 

An Example - By using multiple playlists on a schedule you could have a playlist for each part of the day such as a morning, afternoon, and evening playlist. Just create three playlists as you did in Step 2, name them, and drag them onto the schedule.

Want this schedule every day? 
Command + Click on the day you scheduled and select "Create Day Template" 


Under the Day Template Pane - Press Command and click on the Day Template you just created and select "Default" 

Now that the Day Template is default it will play every day unless specific content is scheduled on the calendar which overrides it. If you need to modify this default schedule, just double click on it under the Day Templates Pane in order to modify it in center of the application. 

To help understand the structure of scheduling it is important to observe that content explicitly scheduled on the calendar will override the default day template which overrides the default playlist. 

Step 4: Publish Presenter file to Presenter Players

 There a three options available to publish content- 

  • Player Targets - a connection is established directly between the creator and the player over a Local Area Network or VPN connection (such as LogMeIn Hamachi). It is recommended to have a wired ethernet connection in order to improve publishing time and reliability.
  • Web Targets - content is published to a web server on the internet and then pulled down by the players on a defined interval. 
  • Offline Update - the player is updated via USB stick with an update package (.prim3 file) prepared by the creator.

Adding a Player Target 
Note: This is a one-time setup; player will only have to be added once.
  1. Click the Project Settings Icon -    and then click on Targets. 
  2. Click on the  Cancel_Button button and select Bonjour
  3. Select your Player from the list. 
  4. Click OK
  5. Enter the Username and Password in-which the player in logged in as
  6. The player should now have a green icon beside its entry. Click Done. 

Publishing to a Player Target
  1. Click the   (Publish) icon in the upper right of the interface.
  2. Your project will now show the status dialog and cannot be edited during this process.
    • The first time your project is published it may take a while depending on the size. Subsequent synchronizations will only send changes to the player and thus will be much quicker.
