Down-projecting footage shot at 48 fps to 24 fps results in what effect when played back at standard speed?

• A. Slow motion
• B. Real-time playback
• C. Time lapse
• D. Freeze frame

Answer: (A)

Down-projecting from a higher capture frame rate to a lower playback rate makes motion appear slower. Shooting at 48 frames per second and playing back at 24 frames per second means each second of real time now requires two seconds of playback, so the action looks slowed down. This is the classic slow-motion effect you get when you use a high frame rate and then play it back at a standard, lower frame rate.
