About this tool
Frame rate arithmetic goes wrong in one specific way: 29.97 and 59.94 are not the same as 30 and 60. They exist because of the colour television standard and they drift against wall-clock time — about 3.6 seconds per hour — unless drop-frame counting is used. Editors handle it, but calculators and delivery specs often do not.
This calculator converts between frame counts, durations and rates, and flags the non-integer rates explicitly. It also names the deliverable each rate belongs to, which is useful when a specification says 25 fps and you need to know why.
Features
- Conversion between frame counts and durations
- Milliseconds per frame for timing work
- Explicit drop-frame warnings for 29.97 and 59.94
- Delivery guidance for each rate range
- Frames per minute for any rate
- Handles fractional frame rates correctly
Frequently asked questions
What is drop-frame timecode?
A counting convention that skips frame numbers to keep 29.97 fps timecode aligned with wall-clock time. It does not drop actual frames from the video — it only changes how the numbers are labelled. Without it, timecode drifts about 3.6 seconds per hour.
Which frame rate should I deliver?
24 fps for a cinematic look, 25 fps for European broadcast, 30 fps for general web video, 50 or 60 fps for sport and gameplay. Match the platform's specification when there is one.
How many frames are in a minute of 30 fps video?
1,800. At 25 fps it is 1,500, and at 24 fps it is 1,440 — which is why 24 fps is sometimes described as 1.44 kfpm.
Does a higher frame rate always look better?
Not always. Very high rates can make film content look unnaturally smooth, which is the effect people call the soap-opera look. Choose the rate that matches the intent of the material.
