In a video digitization system, the frame rate is set incorrectly to 15 fps instead of 30 fps. What is the likely effect?
AVideo resolution will increase
BVideo will appear choppy or less smooth
CAudio quality will improve
DFile size will increase
Step-by-Step Solution
Solution:
  1. Step 1: Understand frame rate impact

    Frame rate controls how many images display per second; lower fps means fewer images and less smooth motion.
  2. Step 2: Identify the effect of halving fps

    Reducing from 30 to 15 fps causes choppiness, not resolution or audio changes.
  3. Final Answer:

    Video will appear choppy or less smooth -> Option B
  4. Quick Check:

    Lower fps = choppy video [OK]
Quick Trick: Lower frame rate makes video less smooth [OK]
Common Mistakes:
  • Thinking resolution changes with frame rate
  • Assuming audio quality is affected
  • Believing file size increases with lower fps
