How many frames are in 5 seconds at 24 fps?
120 frames
5 seconds of 24 fps footage holds exactly 120 frames. Frame numbering starts at zero, so they run from frame 0 to frame 119 — timecode 00:00:00:00 through 00:00:04:23.
How that is worked out
frames = seconds × fps
5 × 24 = 120 frames
Worth knowing
- The count scales with the clip: 2.5 seconds is 60 frames and 10 seconds is 240 frames.
- Each frame holds the screen for 41.667 ms at 24 fps, so trimming a single frame changes the running time by that much.
- The frames field of the timecode runs 00 to 23 before the seconds field moves, so the count ends at 00:00:04:23 rather than at a round number.
- Counting 120 timecode labels at 23.976 fps instead takes 5.005 real seconds, because that rate is 24 slowed by 1000/1001. Read the other way round, a real 5 seconds at 23.976 fps holds 120 frames.

Durations here are real seconds. Over 5 seconds the 1000/1001 NTSC slowdown is too small to change the count — 23.976 fps holds the same 120 frames as 24 fps — but the gap grows to a full frame within a minute.
