You need to determine which channels (hue, luminance, and saturation) you will use to extract your key.
To set keying parameters:
- In the Colour menu, click Secondaries.
The Secondaries menu appears.
- Click the Keyer option box to toggle to the HLS Keyer.
The HLS Keyer appears in the Secondaries menu.
- To select the basis of a key, enable one, two, or all three of the channels. Channel selection depends what you want to base
your key on: chrominance, luminance, or a combination of both.
- To extract a key based on the hue of the selected colour range, enable Hue. To exclude hue from a key, disable Hue.
- To extract a key based on the luminance of the selected colour range, enable Lum. To exclude luminance from a key, disable
Lum.
- To extract a key based on the saturation of the selected colour range, enable Sat. To exclude saturation from a key, disable
Sat.
NoteChrominance is comprised of both the Hue and Saturation channels.
- Enable the Source Primary button to use primary grading results as the input to the keyer.
NoteWhen Src: Prim is disabled, the raw scan is used as the input to the keyer, effectively bypassing any input LUTs and primary
grading that has been applied to your shot.
- Enable the Log to Lin button. See Tools Settings.
- Adjust the Soften slider. See Tools Settings.
