Apply a chromakey FX on the Deltacast source

• Select the layer Deltacast in the timeline and in the Editor tab add an Fx > Chromakey

Adjust the green color setting

• As a Primary color, it is better to choose a mean background color instead of a very light or dark one

*If you really have differente green colors in front of your camera such as a bright green and a bottle green, then it is possible to choose up to three colors using Secondary and Tertiary color.

Adjust the Luma weight setting.

• If the deltacast signal is an Uncompressed RGB, we recommend to set the Luma weight to 0%
• If the signal has a compressed color space such a YUV 4:2:2 or even YUV 4:2:0, then it creates aliasing and the Luma weight need to be set between 50 and 100%

Adjust the settings Threshold and Sharpness settings

• First of all, let’s check the draw mask option to show the transparency mask
• Start by lowing down the sharpness as much as possible but not too low

*A low sharpness is an efficient way to reduce aliasing.
However, a sharpness too low will make transparent objects that are required to be opaque and may induce more visible noise.

Use despil option to remove green from objects

if there are for example clothes of light colors within the scene, the background color has a tendency to “spill” onto them.
In order to remove this undesired behavior, you may use the despill option.

• Adjust this settings until it’s set properly as we did before for the transparency mask
• Choose the intensity of the despill (despill amount). 100% of despill means that the background color is completely removed where the mask is maximum.
  

*The despill option is completely independent from the transparency and does not add any transparency to the image. Despill setting only desaturate the green reflection.

Final adjustements with Smooth Masks option

• If the other parameters are not enough to get a satisfying unaliased mask, you can use the smooth masks option

Everything in a green should turn transparent and we should see behind the content of the 3D Camera_AR.

• Move the Pan, Tilt, Zoom of the real camera to see how well your 3D Camera is set compared to the real camera live feed.
