Question 1

What switcher feature enables switcher manufacturers to keep the rows of buttons to a sensible minimum without curtailing the switcher's special-effects capacity?
A) clip controls
B) flip-flop controls
C) delegation controls
D) color controls
E) wipe controls

Accepted Answer

Delegation controls allow switcher manufacturers to minimize the number of button rows by enabling a single row to control multiple functions or sources, thus not limiting the switcher's special-effects capacity.

Question 2

What is included in the monitor bank?
A) a mix/effects bus
B) a program bus
C) a fader bar
D) delegation controls
E) a preview monitor

Accepted Answer

E

Question 3

Which of the following transitions requires the buses to be delegated to the wipe mode?
A) dissolve
B) horizontal split screen
C) superimposition
D) fade
E) cut

Accepted Answer

A horizontal split screen transition requires the buses to be delegated to the wipe mode because it involves a wipe effect that splits the screen into two parts.

Question 4

If you are setting up a key and you notice that the letters of the title you are using are tearing (breaking up), what switcher control would you use to correct the image of the title so that it is clear and sharp?
A) joystick
B) clipper
C) special-effects fader controls
D) delegation controls
E) chroma-key control

Accepted Answer

The clipper control is used to adjust the key signal's level, which can help in correcting the image of the title to make it clear and sharp by eliminating tearing or breaking up of the letters. This control essentially clips or cuts out the parts of the signal that are causing the issue, resulting in a cleaner key.

Question 5

If the picture breaks up during switching, what could the problem be?
A) the sources are not genlocked
B) the switcher button was not pressed hard enough
C) the transition was not previewed correctly
D) the program bus was used instead of the M/E bus
E) the camera shots are not matched

Accepted Answer

If the sources are not genlocked, it means that they are not synchronized to the same reference signal. This can cause the picture to break up during switching as the switcher may be attempting to switch between two sources that are not in sync with each other.

Question 6

What gel color must you use to neutralize the green background reflections on the foreground during a chroma key?
A) green
B) blue
C) magenta
D) cyan
E) yellow

Accepted Answer

Magenta is the complementary color to green, meaning it is directly opposite green on the color wheel. Using a magenta gel can help neutralize green reflections or spill in a chroma key setup.

Question 7

Posterization of a video image means that:
A) the brightness steps of the image are greatly reduced
B) the image shows only its outline
C) the image is digitally keyed into a poster
D) large block letters appear over the image
E) the brightness is greatly increased

Accepted Answer

Posterization refers to the effect of reducing the number of brightness steps in an image or video, resulting in a more stylized, graphic-looking image with large areas of flat color. This effect is often used in artistic or creative contexts, but can also be unintentional if the image is improperly compressed or processed.

Question 8

You already have up a name key identifying the guest. The director wants another key identifying the name of the program. Which controls would allow you to achieve such a "double key" effect?
A) downstream keyer
B) auto-transition
C) chroma-keyer
D) matte key
E) external key

Accepted Answer

D  E  A downstream keyer, matte key, and external key can all be used to layer additional graphics or text over a video feed, allowing for multiple keys such as identifying both a guest and a program.

Question 9

As you use a switcher to fade from black to camera 1, which switching mode do you assign the M/E buses?
A) program mode
B) preview mode
C) mix mode
D) effects mode
E) preset mode

Accepted Answer

Mix mode is used for transitions such as fading from black to a camera source, allowing for smooth blending between sources.

Question 10

What feature is necessary to have two different framed video sources on the screen at one time?
A) a dissolve
B) a fade
C) a wipe
D) DVE (digital video effects)
E) a key

Accepted Answer

DVE (digital video effects) allows for two different framed video sources to be displayed on the screen at one time through picture-in-picture or split-screen effects. A dissolve, fade, wipe, and key are all useful video effects but do not necessarily cater to the specific feature of having two different framed video sources shown simultaneously.
