Tutorial 6: Video

In a video camera, the sensor that picks up light is called a CCD. CCD stands for:

• color-coding data

• custom color descriptor

• chroma-calculation daemon

• charge-coupled device

• carbon crystal digitizer

A computer’s output on a CRT is calibrated to display an image:

• smaller than the actual monitor’s capability

• larger than the actual monitor’s capability

• exactly the same size as the actual monitor’s

• that adjusts automatically to the monitor’s capability

• of a fixed size; whether it is larger or smaller than the monitor’s capability depends on the monitor

Removing a residual magnetic field that distorts the colors on a television screen is called:

• tracking

• dubbing

• streaming

• flattening

• degaussing

A video signal transmitted with all the signals mixed together and carried on a single cable is called:

• RGB video

• composite video

• component video

• multiformat video

• chroma-key video

Which of the following is not a television signal format?

• MPEG

• NTSC

• PAL

• SECAM

• HDTV

Computer displays draw the lines of an entire frame in a single pass; this technique is called:

• streaming

• progressive-scan

• packing

• flattening

• overscan

The video technique that allows you to choose a color or range of colors that become transparent, allowing the video image to be visible behind those colors in the overlying image, is known by all of the following except:

• blue screen

• Ultimatte

• chroma key

• interlacing

• green screen

Which of the following is a multimedia container format?

• JPEG

• DVD-RW

• ComponentY

• Hi-8

• Ogg

Red or green should be avoided as cue colors because:

• they represent negative ideas in some cultures

• they do not blend well with other colors

• color-blind individuals cannot see them correctly

• they are associated with “stop” and “go”

• they remind people of Christmas

 Which of the following is not a good idea when creating titles (text) to be used in video?

• Fonts for titles should be plain, sans serif, and bold enough to be easily read.

• When you are laying text onto a dark background, use white or a light color for the text.

• Do not kern your letters too tightly.

• If you use underlining or drawn graphics, make sure your lines are only one pixel wide.

• Use a drop shadow to help separate the text from the background.
