Video records at a rate of how many FPS?
24
The shutter in most motion-picture cameras is a
focal plane type and is called a?
Rotary disk shutter.
The standard operating speed for 16mm cameras is?
24 fps.
To portray a subject in slow motion do you record a rate faster/slower then 24fps?
Faster
Motion-picture cameras are classified according to what?
The size (width) of the film they use.
The standard or normal
focal length lens for a 16mm camera is?
1 inch (25mm)
What camera technique should be
avoided because variable darkening of the image results.
Panning
With a motion-picture camera, the final exposure
adjustment is usually made only with the?
Aperture-
because fps rate of the camera determines the shutter
speed
What filters are often used in motion-picture work to help control exposure because
of the limited f/stop and shutter speed combinations
available on motion-picture cameras.
Neutral density filters (ND)
What are some of the advantages in motion video "Videeotape" recording?
-A videotape camera can record black and white
as well as color.
-No time-consuming film processing is required
and recordings can be played back immediately.
-When necessary videotape may be partially or
completely erased and used again for several
more recordings. It can be played back numerous
times and may be stored indefinitely.
-Videotape is edited or assembled more quickly
than film.
-Videotapes are duplicated and distributed easily
to other Navy activities.
What is background sound or “wild” sound. Sound that surrounds the scene or location,
received by the microphone and recorded onto magnetic
tape.
Ambient Sound
What is the ratio of the height to the width of the film or television frame. Three units high to four units wide (3:4).
Aspect Ratio
What is a Beam Splitter?
An optical device within a color
camera that splits the white light into three primary
colors: red, green, and blue.
What is a CCD?
CCD-Charged-coupled device, also called a chip.
A small, solid state (silicon resin) imaging device used
in a video camera instead of camera pickup tubes. Inside
the chip, image sensing elements translate the optical
image into a video signal.
A color standard used by the television industry for the alignment of cameras and videotape recordings.
Color Bars
A loss of part of the video signal, which appears as white glitches. Caused by dirty VTR heads or poor quality videotape.
Dropout
The level of amplification for a video or audio signals. Increasing the video gain increases the picture contrast
Gain
What are Heads?
A small assemble within an audio or video recording system, which can erase, record or playback
the signal in electromagnetic impulses.
Unwanted sounds or electrical interference in a audio or video signal. In the audio track, there is a
hiss or humming sound. In the video picture the
interference appears as “snow.”
Noise
The smallest single picture element with which an image is constructed. The light-sensitive
elements in a CCD (chip) camera.
Pixel
What are Composite (Y/C) and component?
Composite (Y/C) and component all refer to the way
the video signal is treated in the videotape recorder. A
composite video signal means that the luminance
information (“Y” signal), chrominance information
(“C” signal), and the sync information are combined
into a single signal (Y+C+sync)
What causes video drop out?
Videotape dropout occurs when a piece of magnetic
oxide or coating on the tape flakes off or is rough,
causing a “hole” or line of missing information in the
picture when it is viewed on the monitor.
When the electron beam first scans all odd-numbered
lines, from left to right When all odd-numbered lines
have been scanned, it makes up a field. One field
consists of mow many lines?
262.5 lines
When all
even-numbered lines are scanned a second field is
formed. The two fields make up a frame or one
complete television picture. A frame consists of mow many lines?
525 lines
A loss of part of the video signal, which appears as white glitches. Caused by dirty VTR heads or poor quality videotape.

525 lines
This charge-forming-and-scanning is a fast, continuous process. The complete camera tube screen(frame) is scanned how many times per second.
30 times
What are thefour separate
tracks on the tape?
video track
two audio tracks
control track
If what is too low, the recorded image looks grainy and flat.
Brightness level
What are some situations in which you should use manual
focusing?
-When the subject has finely detailed repetitive
patterns
-When one subject is close to the camera and
another is far away
-When the subjects are located behind screens,
nets, or frosted glass
-When objects pass between the camera and the
primary or intended subject
True or false. Situations where there is insufficient light, the subject is strongly backlit, or with subjects consisting of flat colors or little contrast (such as bulkheads or the sky), the autofocusing mode may
not function accurately.
True
When the Hi8 camera is set in the AUTO LOCK position, the shutter speed is set at the normal speed of?
1/60 second
One of the most commonly abused motion-media techniques is?
Panning
Moving a camera up and down vertically is called?
Tilting
Movement in front of the camera, usually that of the subject, is called?
Primary Movement
What in Tertiary movement?
A sequence of shots
from two or more cameras
When recording an event on motion media, there are
three basic shots or sequences you must use what are they?
Long shots (LS), medium shots (MS), and closeup shots (CU)
What is CONTINUITY?
A continuous, smooth, logical and coherent manner.
What screen direction movement shows subjects moving toward or away from the camera?
Neutral screen direction
What screen direction shows subjects moving in
one direction only?
