- 30 fps (Correct answer)
- 10 fps
- 60 fps
- 15 fps
Correct answer: 30 fps
30 frames per second strikes the balance between smooth motion and manageable file size, making it the standard for eLearning screen capture recordings.

- To make video content accessible to deaf or hard-of-hearing learners (Correct answer)
- To reduce video file size
- To replace the script file
- To track video completion in the LMS
Correct answer: To make video content accessible to deaf or hard-of-hearing learners
Closed captions display synchronized text of spoken audio, ensuring learners who are deaf, hard of hearing, or in sound-sensitive environments can access video content.
Question 6: Which audio sample rate is standard for professional eLearning narration recordings?
- 44.1 kHz (Correct answer)
- 8 kHz
- 22 kHz
- 96 kHz
Correct answer: 44.1 kHz
