c. slow motion is achieved by filming at a slower rate than is normal
Explanation:
Slow motion is achieved by filming at a faster frame rate and playing the video in a slower frame rate. When filming is done at a slower frame rate and played at a faster frame rate this is used to make a time lapse video.
Suppose you film something at 240000 frames per second and play it at 24 frames per second then the video will be (240000/24) 10000 times slower.
c. slow motion is achieved by filming at a slower rate than is normal.
Explanation:
Slow motion is the name given to the special film and video effect in which movements and actions in frame are seen over a longer duration than normal, giving the feeling that time itself is slowing down. Although the effect is noticeable only when projected, it can be prepared when shooting or processing images. To cause the slow motion effect, you need to capture frames at a faster rate than normal, and then play back frames at a slower than normal rate.
An aircraft lose altitude when flying from a region of higher temperature to a region of cooler temperature, hence making the reading on the altimeter to be high.
