Deck Playback Control; The Crossfader; The Master Effect; Brightness/Contrast Control - Numark NuVJ Reference Manual

Deck Playback control:

Next to the bank selection display, there are a few controls which can be used to alter the playback of the
cells on that deck:
The top indicator is the playback position inside the current clip.
The bottom indicator controls the speed at which the clip is playing. The center represents a speed of
zero (the clip will be frozen). If the indicator is located in the right side region, the movie will be
played forward while if on the left side region, the movie will be playing backward. The further you
get from the center, the faster the movie will play.
interface, simply click inside the control to move the speed indicator to that point.
adjust the speed of playback using the SPEED sliders on the controller. A vertical bar in the speed
indicator shows the speed point where the movie is playing at nominal speed. When the speed is set
around the nominal speed, the speed indicator will turn red
Please note that the efficiency of playback at non-nominal speed
depends a lot on the type of movie and compression used for the clips.

playing after you release the mouse or the pad on the control surface. If it is deactivated, the cell will
stop playing as soon as you release the mouse/controller pad. You can also activate/deactivate the
mode using the LATCH button on the control surface.
The [SYNC] button engages a 'synchronized playback' mode for the clips.
adapts the movie speed to be 'in sync' with the BPM detected from the audio input. You can toggle
the sync mode from the controller using the dedicated button. When sync is engaged, movie speed
can still be altered by the speed sliders.
The [AUTO] button engages the automated mode for the deck.
automatically trigger cells from the current bank in a random fashion, following the BPM detected
from the audio input. This can be useful if you need a rest in the middle of a performance or simply
want to automatically blend visuals together.

The Crossfader:

The crossfader is located in a central position. Using either
the mouse or the slider on the controller, you can use the
crossfader to blend your movies together. If the fader is on
the far left side, only the output of deck A will be visible,
while if on the far right side, only the output of deck B will be
shown. In intermediate position, both A & B will be blended according to a 'transition' curve that can be
chosen. To select the transition curve, right-click the crossfader and select one of the available transitions.
The controller also features a FADER MODE switch on the front panel that allows selecting among 3 pre-
defined transition curves. For more information on defining the transitions used by the control surface, see
further in the Preferences section.

The Master Effect:

The master effect is an additional effect that can be applied to the
output of the image mix. The master effect can be selected either
from the software interface or from the MASTER FX knob on the
control surface. Each effect allows up to two parameters to be
tweaked with the PMTR1 and PMTR2 knobs on the control surface.
The FX LEVEL (Master FX Mix) knob allows setting the percentage
of the effected image that will go in the final output. You can also
completely bypass the master effect by pressing the MASTER FX
button on the controller.

Brightness/Contrast control:

Before the image is sent to the main output, you can adjust
its brightness and contrast. This allows you to adjust the
image to the room's lighting conditions or to compensate for
a loss/gain of brightness due to heavy image processing and
blending. The contrast and brightness settings can be
controlled either from the user interface or directly from the control surface with the CONTRAST and BRIGHT
knobs. If you don't use this feature, you can bypass it in the Preference dialog – this will save some CPU
power and could slightly improve performance.
