Slideshow Videos Technology & Digital Applications 3 — Questions and Answers
Question 1: What is 'bitrate' in the context of video files?
- The amount of data processed per second, affecting video quality and file size (Correct answer)
- The number of bits in a single video frame
- The speed at which the video uploads to a server
- The sampling rate of the audio track
Correct answer: The amount of data processed per second, affecting video quality and file size
Bitrate measures the amount of data (in bits) processed each second in a video file, with higher bitrates producing better quality but larger file sizes.
Question 2: Which cloud storage service is most commonly integrated with Google Slides for storing and sharing slideshow files?
- Google Drive (Correct answer)
- Dropbox
- OneDrive
- iCloud
Correct answer: Google Drive
Google Slides files are natively stored and synced through Google Drive, enabling real-time collaboration and easy sharing with others.
Question 3: When creating a slideshow video for social media, what resolution is recommended for Instagram Reels and TikTok?
- 1080 x 1920 pixels (vertical 9:16) (Correct answer)
- 1920 x 1080 pixels (horizontal 16:9)
- 1280 x 720 pixels (horizontal)
- 720 x 720 pixels (square)
Correct answer: 1080 x 1920 pixels (vertical 9:16)
Instagram Reels and TikTok are designed for vertical mobile viewing, making 1080x1920 (9:16 aspect ratio) the optimal resolution for these platforms.
Question 4: What does 'lossless compression' mean when saving image files for a slideshow?
- The file size is reduced without permanently discarding any image data (Correct answer)
- The image is compressed by permanently removing some pixel data
- The image is converted to black and white to reduce file size
- The resolution is halved to achieve a smaller file size
Correct answer: The file size is reduced without permanently discarding any image data
Lossless compression reduces file size using algorithms that can perfectly reconstruct the original data, unlike lossy formats such as JPEG which permanently discard some image detail.
Question 5: In Adobe Premiere Pro or similar video editors, what is a 'sequence' or 'composition'?
- A project container that holds all the clips, audio, and effects assembled for editing (Correct answer)
- A single exported video file ready for uploading
- A collection of stock footage assets
- A group of pre-made transition animations
Correct answer: A project container that holds all the clips, audio, and effects assembled for editing
A sequence (in Premiere) or composition (in After Effects) is the editing container where you arrange all media elements on the timeline to build your final video.
Question 6: What is the function of a 'Ken Burns effect' in slideshow video software?
- A pan-and-zoom animation technique applied to still images to add motion (Correct answer)
- A black-and-white filter inspired by documentary filmmaking
- A crossfade transition between two slides
- A method of syncing slide changes to music beats
Correct answer: A pan-and-zoom animation technique applied to still images to add motion
The Ken Burns effect applies slow panning and zooming movements to still photographs to create the illusion of motion and visual dynamism in a slideshow video.
Question 7: Which audio format provides the best quality for background music in a slideshow video while keeping file sizes manageable?
- AAC (Advanced Audio Coding) (Correct answer)
- WAV (uncompressed)
- MP3 at 96kbps
- MIDI
Correct answer: AAC (Advanced Audio Coding)
AAC offers superior audio quality compared to MP3 at the same bitrate and is the preferred format for video platforms like YouTube and Apple devices.
