AP-14 Week 4 Quiz

 AP-14 Week 4 Quiz | Cabrillo College

Question 1

Aperture on a camera lens controls:  

motion and amount of light  

depth of field and amount of light    

amount of light  

depth of field

 

Question 2

A larger aperture, think f/1.4 or f/2, has what effect on depth of field?  

depth of field is shallow, therefore subject in focus but background and forefround out of focus    

depth of field is deep, therefore subject in focus as well as background and forefround are in focus and detailed

 

 

Question 3

Shutter speed is broken into fractions of a second  

True    

False

 

Question 4

In video, a faster shutter speed makes moving objects more clear while a slower shutter speed makes moving objects more blurry.  

True    

False

 

Question 5

ISO controls:  

sensitivity to light    

depth of field  

motion  

amount of light entering camera

 

 

Question 6

Low ISO (100-400):

  

less sensitive to light, more digital noise (lower quality image)  

less sensitive to light, less digital noise (higher quality image)    

more sensitive to light, more digital noise (lower quality image)  

more sensitive to light, less digital noise (higher quality image)

 

Question 7

Frame rate (expressed in frames per second or FPS) is the frequency (rate) at which consecutive images called frames appear on a display. The term applies equally to film and video cameras, computer graphics, and motion capture systems.

  

True    

False

Question 8

Setting your shutter speed to be double that of your frame rate is a fantastic rule of thumb (ex: 24p at 1/50 shutter speed) unless you want to manipulate motion for artistic effect.

  

True  

False

 

Question 9

White Balance set in-camera is how cool (bluish) or warm (orange) your footage is recorded. Sometimes custom setting your white balance (measured with Kelvin Color Scale) in-camera is best for complicated mixed lighting, otherwise auto white balance will do.

 True    

False

 

 

Question 10

What is resolution?

Resolution is how many pixels a video has.

Resolution is a measure of the number of individual pixels a video contains both horizontally and vertically. Some common resolutions are 640x480 (standard definition), 1280x720 (high definition), 1920x1080 (full HD). These are typically referred to by their vertical dimension such as, 480p, 720p or 1080p. Many films and high budget television shows today are recorded at 4k (UHD, ultra high definition). 4K refers to one of two high definition resolutions: 3840 x 2160 pixels or 4096 x 2160 pixels. 4K is four times the pixel resolution, or twice the line resolution (2160p), of 1080p (1920 x 1080 pixels). I recommend for this class you record video at either HD (1280x720) or full HD (1920x1080). Resolution can be selected for artistic purposes that said.

 

Question 11

Which resolution is considered Full High Definition?

  

1920x1080 pixels    

1280x720 pixels  

4096x2160 pixels

 

Question 12

Keep audio recording levels as close as possible to:

  

-12db    

10db  

12db

Consistently going above -10db (towards 0db) doesn’t give you the “headspace” in post production to increase volume, as well as, staying around -12db ensures unforseen spikes in volume from talent or environmnet doesn't result in audio distortion. If you ever reach or exceed 0db you will "clip" the audio and create terrible sounding audio distortion. Staying around -12db is recommended as it gives you enough volume while allowing some "headspace" in post in case you need to raise volume.

 

Question 13

Explain what is RAW, Log, and Standard Video recording, as well as, explain their pros and cons.

Raw/Log is all the data from the camera. The Standard factory setting is a pre-selected rang of data; that saves time on editing and memory. The con to Standard is that it isn't as editable.

LOG is not all the data from the camera sensor, LOG is essentially a more sophisticated Standard Video file that has been tonally flattened and desaturated to make it have more dynamic range during post production, therefore it requires editing because out of camera it looks flat and lifeless.

 

Question 14

Should the internal mic of a DSLR or Smartphone be used to record audio when other external mics are available?

  

No   

Yes
