What is the primary purpose of resizing an image or video?

  1. To adjust the dimensions for a specific purpose

  2. To improve the quality of the image or video

  3. To reduce the file size

  4. To enhance the colors and contrast


Correct Option: A
Explanation:

Resizing is primarily done to modify the dimensions of an image or video to fit a specific requirement, such as a social media post, a website banner, or a video player.

Which interpolation method is commonly used for upscaling images?

  1. Nearest Neighbor

  2. Bilinear Interpolation

  3. Bicubic Interpolation

  4. Lanczos Resampling


Correct Option: C
Explanation:

Bicubic Interpolation is a widely used interpolation method for upscaling images because it produces smoother and more detailed results compared to other methods.

What is the main disadvantage of downscaling an image?

  1. Loss of detail and sharpness

  2. Increased file size

  3. Distorted colors and contrast

  4. Slow processing time


Correct Option: A
Explanation:

Downscaling an image reduces its dimensions, which can result in the loss of fine details and a decrease in overall sharpness.

Which aspect ratio is commonly used for widescreen videos?

  1. 4:3

  2. 16:9

  3. 21:9

  4. 3:2


Correct Option: B
Explanation:

16:9 is the standard aspect ratio for widescreen videos, providing a wide viewing area and cinematic experience.

What is the recommended resolution for a Full HD video?

  1. 1280 x 720 pixels

  2. 1920 x 1080 pixels

  3. 2560 x 1440 pixels

  4. 3840 x 2160 pixels


Correct Option: B
Explanation:

Full HD (High Definition) video has a resolution of 1920 x 1080 pixels, which provides a high level of detail and clarity.

Which file format is commonly used for resizing and editing raster images?

  1. JPEG

  2. PNG

  3. GIF

  4. TIFF


Correct Option: A
Explanation:

JPEG (Joint Photographic Experts Group) is a widely used file format for resizing and editing raster images due to its ability to achieve high compression ratios while maintaining acceptable image quality.

What is the primary purpose of resizing a video?

  1. To adjust the dimensions for a specific platform or device

  2. To improve the video quality

  3. To reduce the file size

  4. To enhance the colors and contrast


Correct Option: A
Explanation:

Resizing a video is primarily done to modify its dimensions to fit a specific platform or device, such as a smartphone, tablet, or television.

Which interpolation method is commonly used for downscaling videos?

  1. Nearest Neighbor

  2. Bilinear Interpolation

  3. Bicubic Interpolation

  4. Lanczos Resampling


Correct Option: B
Explanation:

Bilinear Interpolation is a commonly used interpolation method for downscaling videos because it provides a balance between speed and quality.

What is the main advantage of upscaling a video?

  1. Increased detail and sharpness

  2. Reduced file size

  3. Improved colors and contrast

  4. Faster processing time


Correct Option: A
Explanation:

Upscaling a video can potentially increase the level of detail and sharpness, making it appear more visually appealing.

Which aspect ratio is commonly used for standard definition videos?

  1. 4:3

  2. 16:9

  3. 21:9

  4. 3:2


Correct Option: A
Explanation:

4:3 is the standard aspect ratio for standard definition videos, providing a square-shaped viewing area.

What is the recommended resolution for a 4K video?

  1. 1280 x 720 pixels

  2. 1920 x 1080 pixels

  3. 2560 x 1440 pixels

  4. 3840 x 2160 pixels


Correct Option: D
Explanation:

4K (Ultra High Definition) video has a resolution of 3840 x 2160 pixels, providing exceptional detail and clarity.

Which file format is commonly used for resizing and editing vector graphics?

  1. JPEG

  2. PNG

  3. GIF

  4. SVG


Correct Option: D
Explanation:

SVG (Scalable Vector Graphics) is a file format specifically designed for resizing and editing vector graphics, allowing for infinite scalability without loss of quality.

What is the primary purpose of resizing a raster image?

  1. To adjust the dimensions for a specific purpose

  2. To improve the image quality

  3. To reduce the file size

  4. To enhance the colors and contrast


Correct Option: A
Explanation:

Resizing a raster image is primarily done to modify its dimensions to fit a specific requirement, such as a social media post, a website banner, or a print layout.

Which interpolation method is commonly used for resizing vector graphics?

  1. Nearest Neighbor

  2. Bilinear Interpolation

  3. Bicubic Interpolation

  4. Lanczos Resampling


Correct Option: A
Explanation:

Nearest Neighbor is a commonly used interpolation method for resizing vector graphics because it preserves the sharp edges and lines of the original image.
