Adjust your blacks and your whites in the 2D Histogram node;
Refine your matte in the Matte Edge node;
Mask out troublesome areas of your matte in the GMask node;
Perform colour correction of the front clip in the Master Keyer node or the Colour Curves node;
View the result in the Result node.
Because it is node-based, you have a lot of flexibility with the Modular Keyer. You can:
Choose a different Start Mode to start with a different default keying pipeline. Options are:
Channel Keyer.
GMask. See
GMask (page 743).
HLS Keyer.
Luminance Keyer.
Master Keyer.
RGB Keyer.
RGBCMYL Keyer.
YUV Keyer.
IMPORTANT When you select another Start Mode, any work in progress will be lost and the selected keyer is loaded with
the default settings.
Add other effects nodes from the node bin to further refine your key.
NOTE All of the legacy keyers had a colour section available in the settings. This colour section of the legacy keyers is only carried
over to the Modular Keyer if the legacy keyer setup used the Master Keyer. If any other legacy keyer was used (RGB, Luminance,
etc.), the colour section is discarded when the setup is loaded. Also, motion blur data, from the GMask section of the legacy
keyers is not carried over to the Modular Keyer.
Setting Up the Nodes and Media to Pull a Key
To pull a key, you must first set up your composite in the Modular Keyer.
There are two ways to set up the composite in the Modular Keyer:
Through ConnectFX.
Through the Action Timeline FX.
To set up the composite in the Modular Keyer though Connect FX:
1 From the timeline, select your front clip segment.
2 Click FX and select Create ConnectFX.
You are taken to the ConnectFX view. The schematic is displayed and your front clip is connected to
the output node.
3 From the ConnectFX node bin, drag the Modular Keyer node between the front clip and the output
node and release it when the connection goes from red to yellow.
The front clip is connected to the front (red) input of the Modular Keyer node, which is connected to
the output node.
4 Double-click the back (green) input of the Modular Keyer node.
You are taken to the Viewing panel and the cursor becomes a green arrow, prompting you to select a
back clip.
