If you shoot at 24 fps and project at 24 fps, the motion is at normal speed.

• A. Slow motion
• B. Fast motion
• C. Normal speed
• D. Stop motion

Answer: (C)

Motion speed depends on how fast you capture frames versus how fast you project them. When the frame rate you shoot at matches the frame rate you project, the playback keeps the same timing as real life. So shooting at 24 frames per second and projecting at 24 frames per second means each second of action is shown as 24 frames, preserving real-time pace.

If the projection rate were slower than the capture rate, the motion would look slower (slow motion). If the projection rate were faster than the capture rate, the motion would look faster or choppier. Stop motion involves displaying still frames with noticeable pauses, which isn’t the case when the rates are equal.

So, matching 24 fps shooting and 24 fps projection yields normal speed.
