Advanced Features

Background:

NuVJ allows the possibility to put a background clip that will be displayed if no clip is played on neither of
the two decks or if the [INSTA BLACK] button on the controller is pressed. The background clip is defined in
the Preferences dialog by going to File > Preferences, and can also be replaced 'on the fly' by drag and
dropping a clip on the master preview window. In the Preferences menu you can also activate the usage of
copy & blending modes (see further) between deck A and the background. This option is not activated by
default to avoid any confusion.

Cell parameters and advanced mixing:

When clicking on a cell with the mouse or triggering it with one of the pads, the cell parameter panel at the
bottom of the interface is updated to show settings for the selected cell. To edit a cell's parameters without
triggering it, simply click on the cell using the right mouse button. The parameter panel contains advanced
options that will allow you to take mixing and performances a step further. To illustrate these options, we'll
imagine mixing the two following images:
Deck A:
Deck B:

Copy modes:

Copy modes express the way cells from deck A & B are blended together in the mixer. Unless a special
option is set (see Preferences / Advanced), theses settings will be effective only when a cell is running on
deck B. This is because deck B is virtually considered to be 'on top' of deck A and copy modes define the
way B is 'merged' onto A.
The copy mode defines the mathematical operation used
to combine the pixel color from deck B with the pixel
color from deck A. Let's review them in order, from left to
right.
The default is the copy mode. In this mode, the cell on deck B will simply be mixed with the cell
on deck A, that is to say that the resulting output will be some pixel averaging of each image.
The addition mode is where pixels from B will be added to pixels of A. If this mode is selected
(as well as the subtraction, multiplication, maximum and minimum modes), the effect is maximal
when the mixing slider is all the way on the right.
The subtraction mode is where pixel colors from deck B are subtracted from deck A, resulting
into an 'inverse' blending of B into A.
The multiplication mode is where pixels from deck B are multiplied with the pixels from deck A.
The maximum mode selects pixels from either deck A or B, depending on which one has the
strongest luminance.
The minimum mode selects pixels from either deck A or B, depending on which one has the
lowest luminance.
Please Note:
color or visual selected in NuVJ. This means that you can use copy and
masking options to have the background visual be shown through deck A.
Deck A is also considered to be on top of the background
