|
you have increased it by one f-stop
|
|
|
What is the difference between composite and component video systems?
|
composite video systems use one wire to send a signal that consists of RGB and Y encoded together; easier to use but lower quality picture
component video uses three wires to send three signals: Y, and two color-difference signals, R-Y and B-Y |

What is the advantage of using a VU meter which has a 'heavy' needle?

There are two specific technical differences between a NTSC video system and a PAL system. What are they?

PAL uses 625 horizontal scan lines and runs at 25 fps |
|
|
If you have a monitor which can be switched to underscan, what does that mean?
|
the monitor is showing the full image recorded on the film or videotape; overscan means it is only showing that part of the image that would be visible on a television

|
5000 watts
|
|
|
What does the 1st AC do?
|
operates the follow focus, checks the gate for dirt, and manages the camera equipment
|
|
|
What does the script supervisor do?
|
maintains continuity and makes sure that all the scenes in the script are being shot according to the angles called for
|
|
|
What are the three basic lights used to illuminate the subject in the three-point lighting system?
|
key, fill, back
|
|
|
Tungsten-balanced lights are balanced to what color temperature?
|
3200 K
|
|
|
What kind of microphone must be supplied with a power source (like phantom power or a battery) to operate?
|
condenser mic
|
|
|
For any passage of sound (be it music, speech, or noise) the difference in volume between the quietest point and the loudest is called the _______.
|
dynamic range
|
|
|
What sampling rate do music CDs use?
|
44.1 kHz
|
|
|
What are three microphone pick-up patterns?
|
omnidirectional, cardioid, super-cardioid
|
|
|
What are the common video connectors?
|
UHF (thick protruding pin)
S-video (five-pin) BNC (pin recessed into cylinder) RF or f connector (thin pin) |
|
|
Is DVD a component format?
|
yes
|
|
|
What is an open-ended or two-point edit?
|
you mark the beginning of the clip and mark where to insert it in the sequence and let the computer decide when the clip will end
|
|
|
What is a film-style insert?
|
You attach one clip onto the end of the other and the following clips just roll back in time rather than being overwritten (also called insert, splice, or ripple edit)
|
|
|
What is a video-style edit?
|
You attach one clip onto the end of another and it overwrites whatever clip was originally following that first one (also called an overwrite or an overlay)

What is interlaced scanning?
|
the most popular system in which the camera scans every other line from bottom to top and then goes back to the top and scans all the lines it didn't get the first time. Each progressive scan is called a field. When two fields are shown in rapid succession, they make up one frame.

|
What does a peak reading meter do?
|

|
|
|
How does ALC (automatic level control) work?
|
it automatically chooses a predetermined recording level, but is slow to react to sudden changes in volume
|
|
|
What is equalization?
|
sound filtering done to minimize unwanted low-bass sounds like wind, traffic, and machinery
|
|
|
What is phase cancellation?
|
when you are using two mics to record sound and the peak of a sound wave reaches one mic slightly before or after it reaches the other, diminishing the strength and quality of the sound signal
|
|
