Duration: 60 seconds Frame rate: 29.97 frames per second Rounded frame count: 1798 Actual duration · seconds: 59.993327 Rounding difference · milliseconds: -6.67334
Questions & answers
What does Video Frame Count Planner calculate?
Calculate frame count and actual duration after whole-frame rounding.
Which units should I enter?
Duration uses seconds. Frame rate uses frames per second. Convert values to these units before calculating.
Which formula does it use?
Frames = round(duration × FPS); actual duration = frames/FPS.
What does the included example show?
Duration: 60 seconds; Frame rate: 29.97 frames per second. Result: Rounded frame count = 1798; Actual duration · seconds = 59.993327; Rounding difference · milliseconds = -6.67334.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
