Production notes

What this result means

Convert a video duration to a frame count or frames back to duration at common and custom frame rates. Results are intended for planning and convenience; confirm critical values in your editing, encoding, or delivery system.

Useful for

  • Planning animation or VFX frame totals
  • Translating render frames into runtime
  • Checking timeline duration at a specific cadence

Assumptions

  • Duration-to-frame results are rounded to the nearest whole frame.
  • Fractional rates are calculated using their exact 1000/1001 values where selected.
  • The display is elapsed time, not drop-frame timecode.

Limits & checks

  • A media file may include variable frame rate timestamps.
  • Rounding can move a boundary by half a frame.
  • This does not account for handles, missing frames, or slate frames.

FAQ

Before the final export

How many frames are in one minute at 24 fps?

Exactly 1,440 frames.

Is 23.98 the same as 23.976?

23.98 is commonly shorthand, but the precise video rate is usually 24000/1001, about 23.976.

Why round duration to a frame?

A constant-frame-rate sequence cannot contain a fraction of a frame.
