resulting from incomplete suppression. While coring can improve some
keys, it can easily be over done. Coring thresholds much above black will
affect dark grays that are actually part of the foreground subject, making
the chroma key composite look unnatural.
Fringe is used to restore color to the gray portions of the foreground color
resulting from secondary suppression adjustments. This control is only
active when secondary suppression is on.
Shdw provides controls of shadows that fall on the backing. Shadow Clip and
Shadow Gain allow selecting the range of the luminance portion of the fore-
ground that produces a shadow. Shadow Density is an opacity control for the
shadow and adjusts how much shadow is added to the background.
Pattern Mix
The Kayenne system can combine the complex wipe pattern generators
(
Wipe 1 and Wipe 2 ), to create a wide variety of customized wipes.
To Create a Pattern Mix on Wipe 1:
1. Double press the Wipe 1 button in the Transition Module. This selects
Wipe 1 as the next transition type, and also opens the Wipes menu with
Wipe 1 delegated for control.
2. Select the Wipe 1 pattern to be used by touching the Ptn data pad in the
C1 Generator pane, and then selecting one of the displayed patterns.
3. Select the Wipe 2 pattern by touching the delegation button in the W2
column, and then select a displayed pattern different from Wipe 1.
4. Touch the Mix data pad located to the right of Ptn data pad. Additional
control buttons will appear at the bottom of the menu.
5. Delegate that ME for preview in the System Bar.
6. Press the Trans PVW button in the Transition Module, and move the lever
arm part way. This will display the Wipe 1 pattern on preview.
7. Touch the delegation button in the W1 column to delegate the menu to
control the Wipe 1 pattern generator.
8. Touch the Pattern Mix button so its indicator illuminates. The preview
monitor will now show the combined Mix 1 and Mix 2 pattern.
9. You can select the type of pattern mix with the Mix type buttons ( Mix ,
NAM + , NAM – ). The NAM buttons are used for And or Or pattern mixing.
10. You can also adjust the amount each wipe pattern contributes to the mix
with the
Ratio control. At 50%, each pattern contributes equally. At 25%,
the other pattern contributes only 25% to the final pattern.
