Slideshow Videos Technology & Digital Applications 4

Question 1

What is the primary advantage of using vector graphics (SVG) over raster images (JPEG/PNG) in digital slideshows?

Accepted Answer

Vector graphics scale to any size without losing quality

Answer

Vector graphics are defined by mathematical equations rather than pixels, so they can be scaled up to any size without becoming blurry or pixelated.

Question 2

In slideshow video creation, what does 'rendering' refer to?

Accepted Answer

The process of computing and generating the final video file from the project's raw elements

Answer

Rendering is the computational process where the software combines all layers, effects, transitions, and audio to produce the final playable video file.

Question 3

Which technology allows slideshow videos to stream smoothly over the internet by adjusting quality based on connection speed?

Accepted Answer

Adaptive Bitrate Streaming (ABR)

Answer

Adaptive Bitrate Streaming automatically switches between different quality levels of a video in real time based on the viewer's available bandwidth, reducing buffering.

Question 4

What does 'DPI' stand for and why does it matter when preparing images for slideshow videos?

Accepted Answer

Dots Per Inch; it affects print quality but screen output is determined by pixel dimensions

Answer

DPI (Dots Per Inch) is a print measurement; for screens and video, only pixel dimensions (e.g., 1920×1080) matter, so DPI settings do not affect how an image looks in a video.

Question 5

Which feature in PowerPoint and Google Slides allows you to record narration audio directly synchronized with slide transitions?

Accepted Answer

Record Slideshow / Record Presentation

Answer

The 'Record Slideshow' feature captures spoken narration and slide timings simultaneously, which can then be exported as a video with the audio already synced.
