1
What is split-screen video analysis?
Model answer
Split-screen analysis shows two clips side by side on one screen. A performer can be compared with an elite model or with an earlier attempt.
2
How can slow-motion replay help a high jumper?
Model answer
Slow motion reveals fast actions such as the take-off and the arch over the bar. Faults invisible at normal speed can then be corrected.
3
What is frame-by-frame analysis?
Model answer
Frame-by-frame analysis steps through footage one still image at a time. The coach can pause at key positions and measure joint angles.
4
What are the advantages of video analysis?
Model answer
Video footage can be replayed many times at any speed. Visual feedback is easy for learners to understand. Stored footage also builds a record of progress.
5
What are the disadvantages of video analysis?
Model answer
Good cameras and software can be expensive, and analysis takes time and expertise. A single camera angle can hide important detail.
6
How is video used in elite sport beyond coaching technique?
Model answer
Analysts use video to scout opponents and review team tactics. Officials use video replays to check decisions.
