- SMOOTH MOVE EFFECT
• Smooth Move layer control the acceleration of the layer. The time
can be different between the opening and closing layer,
- WORKING WITH DSK (Chroma / Luma key)
• QuickVu allows to use a live source with green or blue (or any
color) background and to key it over another live input,
• Background is removed and replaced by another source,
• Title can be keyed (DSK) on Analog or Digital Sources.
To use keying, first select a source in the desired layer:
Layer button > source number button
Then in the main menu, select the Keying/Titling menu.
You now have several choices to key your sources. The Luma Key and the Chroma Key based on the Luma
pixel values and the Chroma pixel values and for both an additional Titling menu which can be useful to
choose the transparency value of your keying.
Keying/Titling menu > Type menu > Select your keying type
Once your keying mode is selected, the QuickVu provides you some keying advance setting:
For Luma Key:
• Luma Keying is used to key from a particular luminous intensity. It produces a hard edged key based on
intensity, which is most suitable for titling effects. You can choose to key things that are extremely dark or
extremely bright and keep everything in between, or invert to key only things that are of a medium intensity.
• The black and white levels define where to begin the keying. In the range 0 to 255, 0 represents no luminance,
or black and 255 represents full luminance, or white.
- Level Black: As the Black Level is changed from 0 to 255, things that are black are first keyed out, followed
by dark grey, then light grey, and so forth, until the entire picture is keyed out at 255.
- Level White: As the White Level is changed from 255 to 0, things that are white are first keyed out,
followed by light grey, then dark grey, and so forth, until the entire picture is keyed out at 0.
