How many frames are in 10 seconds at 25 fps?
250 frames
10 seconds of 25 fps footage holds exactly 250 frames. Frame numbering starts at zero, so they run from frame 0 to frame 249 — timecode 00:00:00:00 through 00:00:09:24.
How that is worked out
frames = seconds × fps
10 × 25 = 250 frames
Worth knowing
- The count scales with the clip: 5 seconds is 125 frames and 20 seconds is 500 frames.
- Each frame holds the screen for 40 ms at 25 fps, so trimming a single frame changes the running time by that much.
- The frames field of the timecode runs 00 to 24 before the seconds field moves, so the count ends at 00:00:09:24 rather than at a round number.

Durations here are real seconds. Over 10 seconds the 1000/1001 NTSC slowdown is too small to change the count — 23.976 fps holds the same 240 frames as 24 fps — but the gap grows to a full frame within a minute.
