Frame Rate Converter
Convert frame counts and durations across frame rates.
Frames, time, and fps
Video runs at a fixed frame rate — 24 for film, 30 or 60 for most digital — and frame count is simply duration times fps. Ten seconds at 24 fps is 240 frames.
It helps when conforming footage shot at one rate into a timeline at another, where a mismatch means dropped or duplicated frames and audio that gradually drifts out of sync.
Why 23.976 exists
Broadcast rates like 29.97 fps come from NTSC timing, which is why frame math rarely lands on round numbers. Your values stay in the browser and are never uploaded.
Frequently Asked Questions
How does the frame rate converter work?
Time equals frames divided by frames per second. 240 frames at 24 fps equals 10 seconds.
When should I use this tool?
Use it for animation timing, video edits, sprite sheets, time-lapse planning, and production notes.
What is the main limitation?
Drop-frame timecode has special broadcast rules; this tool handles straight frame math.
Is this converter private?
Yes. It runs entirely in your browser, so your values are not uploaded or stored.
