KEYING FEATURE
With the keying feature, you will be able to key easily a color
space or a specific luma on an input.
NeXtage 16 offers an individual keying for each input. Into
the input settings, find the keying menu:
YOU HAVE 3 WAYS OF USING THE KEYING:
- COLORKILLER: classic color keyer deleting a specific color space defined by user.
- LUMAKILLER: Luma color keyer deleting a black & white range.
- CREMATTE® : The new algorithm of color keying developed by Analog Way. This keying will per-
form advanced effects on transparent items, smooth edge and color correction.
- INVERT BUTTON: At any time you can choose to invert the actual keying using this button.
- DSK TITLING: After your keying, the DSL titling feature allows
you to play with the transparency of your deleted pixels. Ena-
bling this, simply adjust the opacity settings to make your
keyed pixels less or more dark.
HOW TO USE THE CHROMA KEYING:
Keying setup can be done either by setting directly color references and tolerances or by using the color grab
assistant. When using the assistant, select the color area you want to mask and click ADD AREA .
Color areas are cumulative, if the results are not satisfactory, click the Reset button and then grab another
area.
- Set it manually looking at the color change into Current color. If you want, you can quickly
select a color from a color panel, clicking on Import from RGB color.
- Manually: Set the Hue and luminance to choose the color
space you want to delete into your image.
Then click on the color itself to obtain the color panel.
Once your main color is chosen, you can define a degree of tolerance around this
color. The tolerance will define, around the main color, an area that will be keyed too.
