Dante Level 1 - Chapter 5 - Basics of Digital Video

What is the aspect ratio commonly associated with high definition or HD video?

• 4:3

• 16:9

• 1.85 to one

• 3:2

What does anamorphic setting on a television adjust?

• The color balance

• The contrast ratio

• The aspect ratio

• The resolution

What is the main purpose of using letterboxing in videos?

• To enhance the audio quality

• To fill the unused space on the screen

• To combat flickering

• To maintain the original aspect ratio of the video

What is the difference between progressive and interlaced images?

• Progressive images are drawn in two fields, while interlaced images are drawn in a single frame

• Interlaced images are used to combat flickering, while progressive images are not

• Progressive images are more common today, while interlaced images were used in early television

• Interlaced images are more common today, while progressive images were used in early television

What is the result of using a theater projector's anamorphic lens?

• It decreases the resolution of the image

• It stretches the image to fill the screen

• It changes the color balance of the image

• It reduces the aspect ratio of the image

What does the first digit represent in the encoding descriptions of video pixels in a grid of four by two pixels?

• The brightness or the color information for the two by two pixel block

• The number of pixels in the first row with their own chroma or color information

• The number of pixels individually captured

• The number of encoding schemes available

Which of the following is true about the 4:4:4 color sampling scheme?

• It has its own color data for every pixel in the two by two pixel block

• It combines color and brightness information for two pixels

• It represents the number of pixels in the second row with their own color information

• It is used primarily for black and white video

What is the benefit of using high dynamic range or HDR in video?

• It allows for the encoding of video at higher frame rates

• It captures the human eye's capability of picking up incredible differences, from light to dark

• It reduces the overall brightness of an image

• It is only supported in Dante AV version 1.3 or lower
