Overview
This lesson introduces GeoFocus. GeoFocus enables you to change the map cut–out. This can be achieved by editing the Geo focus info values, selecting a Geo favorite or using Edit mode. Furthermore, the transition from one map to another is discussed.
| Prerequisites: Lessons 01, 03, and 04 |
What Is GeoFocus?
GeoFocus
GeoFocus is the geographical position, Zoom and Aspect Ratio of the Segment’s view of the map.
Each Segment can have its own GeoFocus.
When adding a Geo referenced Subscene or Background Map, a Geo Layer is created and the GeoFocus activated. The initial values of the Segment are the same as the Geo referenced Subscene or Background Map.
Activate or deactivate GeoFocus
GeoFocus is activated using the GeoPin.
Click on the GeoPin checkbox to activate it or deactivate it:

If the GeoPin is not explicitly set, the Segment will inherit the GeoFocus values from the previous Segment containing an activated GeoPin.
If the map cut–out is not what you are expecting, look for an active GeoPin occurring earlier in your Playlist.
Several Geo Layers
You might have several Geo Layers in a Playlist. In this case, the GeoFocus applies to the first layer (topmost) that holds content for the segment. This is identified as the Target layer in the Geo focus info window. If there is no Geo Layer, GeoFocus does not apply.
| See lesson 04 for more info. |
Changing GeoFocus
You can change GeoFocus values:
- By manually changing them
- By changing them in Edit mode
To manually change GeoFocus values, click on the Geo focus info next to the GeoPin. Edit the Longitudinal, Latitudinal, Zoom and Aspect Ratio values as desired.
See Lesson 7.2 for an illustration of this:
Image description: Manually editing GeoFocus values
The Longitude and Latitude values define the position at the centre of the Screen.
The Zoom value defines how close–up the map will be shown (the higher the value, the closer the view).
The Aspect Ratio will stretch the map. The Aspect Ratio defines the relation of the x axis to the y axis. For HD broadcasts, the value is typically 1.778.
| Note: The Projection type can only be changed via the Geo Layer (see Lesson 4). |
Edit mode
It is also possible to change GeoFocus values by moving a map to a new position in Edit mode.
You can access Edit mode:
- By double-clicking on a segment thumbnail
- By clicking on the Edit mode button
In Edit mode, the GeoFocus modification icon needs to be selected to make changes to the GeoFocus values.

The GeoFocus modification icon is highlighted when selected:

Once activated, you can change GeoFocus by clicking and dragging the map to a new position. Use the mouse wheel to zoom in or out. Roll the wheel forward to zoom in, roll the wheel backwards to zoom out.
To quit Edit mode:
- Press the Escape key three times in quick succession
- Click the Exit icon located at the bottom right hand corner of the screen

Geo Favorites
Geo favorites are a feature enabling a presenter to save GeoFocus values.
To add a Favorite, click the Geo focus info button.
Then click the Add to favorites button (the floppy disk icon in the upper right–hand corner). Give the file a name and then click Save.

A thumbnail previewing the GeoFocus values is automatically created:

Click the Favorites button located next to the Geo focus info button to access your Favourites. Double click on a thumbnail to set the GeoFocus values.
Geo favorites are applied when selecting. Overwriting existing geo favorites will not affect playlists where it has been used
| Geo favorites are part of the DesignModel and can be reused in other Playlists. You can quickly and easily create a library of pre–sets in this way saving you time and effort. |
Geo Transition
Geo transition defines the time it takes to interpolate between one set of GeoFocus values and another set of GeoFocus values.
To interpolate the map from one cut out to the following, you need to set the transition time.
In the Geo focus info, you will find a transition-in in seconds which is the duration that will be used for zooming from the last map cut out to the one on the selected segment. Furthermore, it is possible to delay that transition, for example to fade out several objects first.
Lesson 7.8 illustrates this.
Image description: Setting the Transition-in value
In this example, the value is set to 3 seconds.
| Note: Transition–in values cannot be negative and must be shorter than the duration of the Segment. |
