2025.02.11 - Added a functioning key for clear. Pressing the spacebar now acts as a clear key. Bug fixes and a total refresh of the UI. Now accepting donations via Cash App.
2022.01.25 - Added 25fps that was mysteriously absent from the previous version.
Originally written in 2007, Rob's Timecode Calculator performed simple calculations accurately, but had certain bugs that made it frame-inaccurate in certain situations. It now calculates dropframe and non-dropframe timecode much better, and so far, without bugs. And as an added bonus, there is now a tape that records all of your calculations until you clear the tape, or reload the page.
Thanks to David Heidelberger, and Andrew Duncan for their implementation of dropframe timecode conversion.
How to use: Enter in your timecode using your computer's keypad or by clicking the buttons above. All numbers entered are treated as timecode, except when multiplying or dividing. Timecode may be formatted as follows:
Your timecode will be corrected according to the framerate set above. So if you enter 0125+ and your framerate is set to 23.98, your timecode will be corrected to 00:00:02:01. When multiplying or dividing, the number entered following the operator will be treated as a number, not timecode. And besides, who needs to multiply timecode by timecode?
The memory keys function like those on a calculator, and the tape button will show you all of the calculations since the last time you cleared the tape. Memory and Tape text is stored in a local cookie. There are no trackers on this page and no personal info is being collected.
