With the Keyer Framestore (KFS), you can mix, wipe, and use effects in conjunction with your keyed sources to create dynamic multi-key virtual sets. Each Keyer Framestore you add allows for an independent key with it’s own background and key settings. Use this guide for setting up and using the Keyer Framestore.
Once 3.4 or later software and the Keyer Framestore is installed, initiate a KFS by right-clicking in one of your soft buttons on the Program or Preview bus row, and choose Create Keyed Framestore. The KFS soft button can now be used in your Program/Preview bus rows as a source. (NOTE- You do not need to use the Key Bus to use the KFS card) By default the KFS will be set up as a Luma key using Program as the key source and color bars as a background. To unload the KFS, simply right-click on the KFS button in any bus row, and choose Unload Keyed Framestore. To make changes to your KFS, click on the Info button when a KFS is loaded in the bus rows.
The Framestore Keyer Settings panel (Figure 1.1) allows you to change the settings of your KFS in order to key out the proper portions of your signal. To access this panel, click on the Info button located below the KFS button in your bus rows. Here is how to adjust the settings:
Figure 1.1
The large Keyed Framestore button (figure 1.2) at the top of this panel allows you to select the KFS you are using. One card can support two KFS’s but will only allow cuts between them.. If you want to do multiple camera angles with transitions it is suggested that you have at least two cards.

In order to save your KFS settings, simply click and drag the Keyed Framestore window into a bin, and the setting is saved. To use a saved setting, simply click and drag the setting back into the Keyed Framestore window.
The Input/Key (Figure 1.3) window allows you to select the source you are wishing to apply the KFS setting to, including Program Out, and any source input installed in your GlobeCaster, Click in the window and choose the source desired.
The Chroma Keyer Settings (Figure 1.3) window shows you a visual representation of the KFS settings.
The Background (Figure 1.3) window allows you to assign a background images (.tfs format) to your KFS. Simply drag the image into this window. You can also drag and drop .TFS (GlobeCaster stills) onto the KFS Button on the Program or Preview row.
Clicking the Keyer Mode (Figure 1.3) button, next to the Chroma Keyer Setting window, allows to select the keyer mode. Choices include: Off, Normal, Mix, Add, Luma and Ext Alpha. (see page 54 of the Switcher Manual for definition of these options).

The Keyer Settings button allows you to chose either Luma or Chroma Key Settings, and gains you access to the Settings Control sliders below. Those sliders control: Key Hue, Key Sat (saturation), Width, Low Sat, Softness
- Key Hue: The color you are wishing to key out of the signal
- Key Saturation: The amount of the color you selected that is keyed out
- Width: The width of the color value
- Low Saturation: Not enabled.
- Softness: Softens the edges to create a smoother looking key.
It is recommended that you use these settings in this order:
- Width – (start with a value of 30)
- Key Sat - (50)
- Key Hue - (330 for blue, 240 for green)
- Softness - (10)
- Low Sat is not enabled.
The Garbage Matte (Figure 1.4) is a feature that allows for the removal of unwanted parts of the image, thus allowing for a cleaner key, particularly around the edged. The Garbage Matte window shows a visual representation of your Garbage Matte settings. Below this window are the Garbage Matte Control sliders. These control the Top, Bottom, Left, Right, HSoft (horizontal softness) and Vsoft (vertical softness).
- Horizontal Softness: Softens the edges of the Left and Right controls
- Vertical Softness: Softens the edges of the Top and Bottom controls
The Invert button will allow you to invert your Keyer Settings. The Fade setting controls a dissolve of the background when it is replaced by drag and drop. (you should see the background dissolve when there is a value in the fade setting)
