How to Select Your Key Source and Adjust Your Key Settings
The first step is to select your key source and adjust your key settings. Your key source is the video that you want to remove the background from and replace it with another video or image. Your key settings are the parameters that determine how the background is removed and how the edges are blended.
To select your key source, go to the Key Source section on the left side of the window. You will see two options: SDI Input and HDMI Input. Choose the option that matches the input that you have connected your key source to. For example, if you have connected your key source to SDI input 1, choose SDI Input.
To adjust your key settings, go to the Key Settings panel below the Key Source section. You will see four tabs: Chroma Key, Luma Key, Linear Key and Pattern Key. Choose the tab that matches the type of key that you want to use. For example, if you want to use a chroma key, which is a key based on color, choose Chroma Key.
Depending on the type of key that you choose, you will see different settings that you can adjust. For example, if you choose Chroma Key, you will see settings such as Key Color, Tolerance, Softness and Spill Suppression. You can use these settings to fine-tune your key by adjusting the color range, edge smoothness and color spill of your key source.
To adjust a setting, you can either drag the slider or enter a value in the box next to it. You can also use the eyedropper tool to pick a color from your key source by clicking on it. You can also use the invert button to invert your key by clicking on it.
As you adjust your key settings, you will see the result in the Preview section on the right side of the window. You can also see the result in the Output section if you have connected an external monitor to your output.
How to Select Your Fill Source and Adjust Your Fill Settings
The next step is to select your fill source and adjust your fill settings. Your fill source is the video or image that you want to replace the background of your key source with. Your fill settings are the parameters that determine how the fill source is blended with the key source.

Choose the option that matches the source that you want to use as your fill source. For example, if you want to use a still image as your fill source, choose Still Image.
To adjust your fill settings, go to the Fill Settings panel below the Fill Source section. You will see settings such as Opacity, Position, Size and Rotation. You can use these settings to fine-tune your fill source by adjusting its transparency, location, dimension and angle.
To adjust a setting, you can either drag the slider or enter a value in the box next to it. You can also use the buttons to reset, center or flip your fill source by clicking on them.
As you adjust your fill settings, you will see the result in the Preview section on the right side of the window. You can also see the result in the Output section if you have connected an external monitor to your output.

To preview your keyed output on your computer screen, go to the Preview section on the right side of the window. You will see a video window that shows your keyed output. You can also see a toolbar below the video window that lets you control the playback of your keyed output.
