If you shoot 48 fps and project it at 24 fps, what will the result be?

• A. Slow motion
• B. Normal speed
• C. Time lapse
• D. Fast motion

Answer: (A)

When you capture at a higher frame rate than you play it back, the motion slows down. Here, you record 48 frames every second but project them at 24 frames per second. That means each real second yields 48 frames, but those frames are shown over 2 seconds of playback, so the action runs at half speed. That’s why the result is slow motion. Not normal speed because playback doesn’t match the capture rate. It isn’t time lapse or fast motion, which involve different relationships between how many frames are captured and how many are displayed.
