We need to isolate the player in the video coming from your camera so your background doesn't

show up in your mixed reality video. MixCast Studio offers two ways to do this, both with their

own strengths.

Option 1: Chroma Keying

If you have a green screen or blue screen your best option is probably Chroma Keying. This

process removes a selection of colours from the background, resulting in only the player

appearing in the video.

1. Open the "Subject" menu

2. Change your isolation mode to Chroma Key

3. Click the eyedropper icon and then click and drag the dropper across the green area of your

screen

Tip: Use Ctrl-Z to undo your last click if you accidentally key the wrong colours

Tip: Use Spill Feathering to soften the edges of the key and reduce visual noise

Option 2: Static Subtraction

If you don't have a single-colour background, use Static Subtraction. This process takes a

snapshot of your background (without the subject present) and 'subtracts' it. When the subject

steps back in front of the camera they appear because they differ in colour and lightness from

the background behind them.

1. Open the "Subject" menu

2. Change your isolation mode to Static Subtraction

3. Leave the scene so only the background is shown on video and click Capture Background

4. Like Chroma Keying, use Feathering to soften the edges of the subtraction

Tip: Increase the time MixCast Studio samples the background to improve the subtraction

quality

Note: Tracked cameras are not supported when using static subtraction.
